Hylo is a decentralized finance (DeFi) protocol built on the Solana blockchain that introduces a dual-token system: hyUSD, a decentralized stablecoin backed by liquid staking tokens (LSTs), and xSOL, a synthetic asset providing long-term leveraged exposure to SOL.
Hylo Referral Code — DSEZE0 and Mint xSOL and hyUSD and earn upto 17% yield on your stable coins.
The protocol is fully permissionless, non-custodial, and autonomous, avoiding traditional finance dependencies and real-world assets.
Designed for scalability, composability, and yield efficiency, Hylo leverages staking derivatives to create a self-contained monetary system native to Solana, with built-in risk management and slippage-free liquidity mechanisms.
Its goal is to redefine how stable value and leverage are accessed in decentralized markets.
Why is Hylo Important in the Current DeFi / Solana Landscape?
The DeFi landscape — particularly on Solana — is maturing rapidly, but still grapples with key limitations:
Overreliance on centralized stablecoins like USDC.Short-term leverage products with high funding volatility.Fragmented, risky collateral sources.Poor integration of staking yield in DeFi primitives.
Hylo addresses all of these pain points in one integrated, protocol-native system
Stablecoins without CeFi dependency: Hylo’s hyUSD avoids fiat or off-chain assets entirely, solving a major systemic risk in Solana DeFi: dependence on USDC and similar custodial coins.Leverage built for conviction, not speculation: xSOL offers long-term exposure to SOL with built-in yield and without the constant liquidation or funding-rate risk typical in perpetuals.LSTs as core collateral: By using a basket of Solana LSTs (e.g., mSOL, jitoSOL), Hylo turns network staking yield into a sustainable financial primitive — essentially acting as on-chain bonds.Slippage-free liquidity: All minting and redemption happen against the protocol itself, maintaining deep liquidity and removing reliance on AMM or third-party markets.Protocol-level autonomy: No fund managers, oracles, or external price feeds control value flows — Hylo is engineered for composability and decentralization from day one.
In short, Hylo is not just another stablecoin or leverage tool — it’s an independent, yield-aware financial system for Solana-native users.

Hylo represents a next-generation DeFi protocol that reimagines stable value and leverage for a decentralized, yield-aware future — without relying on traditional finance, centralized stablecoins, or volatile leverage instruments. By integrating liquid staking, synthetic assets, and autonomous protocol economics, Hylo builds a resilient, Solana-native foundation for the next evolution of decentralized money.
Introduction to Hylo
Background of DeFi on Solana
Solana has rapidly emerged as a leading smart contract platform, prized for its high throughput, low fees, and parallel transaction processing — an ideal environment for decentralized finance (DeFi) innovation. Over the last few years, Solana has cultivated a vibrant DeFi ecosystem including DEXs (like Orca and Jupiter), lending protocols (MarginFi, Solend), and liquid staking solutions (Marinade, Jito, Blaze).
Despite its growing maturity, Solana DeFi still inherits several structural problems from broader DeFi:
Overreliance on centralized stablecoins
The majority of value in Solana DeFi is denominated in centralized stablecoins like USDC, introducing counterparty risk, regulatory exposure, and off-chain fragility. In short, the foundation of many “decentralized” apps remains centralized at the core.Leverage products are short-term and speculative
Perpetual futures dominate leveraged exposure in DeFi, but they are often unsuitable for long-term conviction due to liquidation risk, funding fees, and volatility. Most tools cater to traders, not long-term investors.Poor integration of staking yield
Solana’s native staking yield is underutilized in core financial primitives. Although LSTs exist, few protocols use yield productively within money markets or stablecoin systems.Fragmented and liquidity-reliant architectures
Many DeFi protocols rely heavily on external AMMs, liquidity incentives, or oracle pricing, creating complex interdependencies and attack vectors.
Solana has the infrastructure to support the next generation of DeFi, but it still lacks foundational protocols that:
Use on-chain-native collateral (not off-chain dollars)Enable productive use of staking yieldOffer composable, long-duration leverageOperate in a fully autonomous, self-contained manner
This is where Hylo enters the picture.
What Pain Points Does Hylo Aim to Solve?
Hylo’s architecture directly targets and resolves the following DeFi shortcomings:
1. Dependence on Centralized Stablecoins
Most DeFi protocols on Solana rely on USDC, a fiat-backed, centralized stablecoin issued by Circle. This introduces:
Censorship riskRegulatory exposureCustodial trust assumptionsIncompatibility with DeFi’s decentralization ethos
Hylo Solution
hyUSD, Hylo’s stablecoin, is backed 100% by on-chain collateral — a diversified basket of liquid staking tokens (LSTs). No fiat. No real-world custodians. No off-chain oracles.
2. Short-Term, Liquidation-Prone Leverage
DeFi leverage is dominated by perpetuals or isolated margin platforms. These:
Require constant managementAre vulnerable to liquidationDisincentivize long-term positions due to funding volatility
Hylo Solution
xSOL provides persistent, synthetic leverage on SOL without liquidation risks or funding fees. Built for long-term holders, not short-term traders.
3. Yield Waste in Collateral Systems
Protocols like MakerDAO require users to overcollateralize with idle assets, which don’t earn yield. Solana, with its native staking yield, offers a better design surface.
Hylo Solution
Collateral in Hylo is made up of yield-bearing LSTs. The protocol design captures this staking yield to support:
Peg stabilitySustainable protocol revenueOptional user yield via hyUSD+ vaults
4. Reliance on Third-Party Liquidity and Oracles
Many protocols depend on external AMMs (e.g., Orca pools) for liquidity and on price oracles (e.g., Pyth, Switchboard) for collateral valuation — both are potential points of failure.
Hylo Solution
Hylo’s minting and redemption logic is self-contained. There is:
No reliance on liquidity poolsNo slippage at mint/redeemNo external oracles — value calculations are entirely internal, based on pre-defined protocol math
Hylo enters the DeFi scene not as a derivative of existing models, but as a first-principles rethink of decentralized money. By eliminating fiat dependencies, extracting staking yield from collateral, and embedding composable leverage into its protocol layer, Hylo positions itself as a foundational money layer for Solana.
Its self-contained architecture, zero-slippage liquidity, and long-term asset strategies provide a sustainable and decentralized alternative to the current stablecoin-leverage-perp trifecta dominating DeFi.
Hylo Overview
Hylo is a decentralized finance protocol native to the Solana blockchain that offers two core financial primitives:
hyUSD — a decentralized stablecoin backed by liquid staking tokens (LSTs).xSOL — a tokenized product offering long-term leveraged exposure to SOL.Mint hyUSD and xSOL using this link.
Unlike traditional DeFi platforms that depend on centralized stablecoins or price oracles, Hylo builds a self-contained, permissionless system that functions like an on-chain “central bank” for Solana — complete with mint/redeem mechanics, collateral optimization, and embedded staking yield.
Hylo is engineered to be more than a set of DeFi tools — it is a composable, yield-native monetary layer that aligns capital efficiency with decentralization.
Mission and Guiding Principles
Hylo’s mission is to establish a fully autonomous, Solana-native financial system that is sustainable, composable, and maximally decentralized. This vision is governed by four core principles:
1. Solana-Native
“We build performant products meant to compose, scale, and evolve with Solana DeFi.”
Hylo is built exclusively for Solana, optimizing for its:
High throughputLow feesParallel execution (via Sealevel runtime)
This enables fast, cost-efficient, and low-latency DeFi primitives that seamlessly integrate with the broader Solana ecosystem, including liquid staking protocols (like Jito, Marinade) and DeFi venues (like Jupiter, Kamino, Meteora).
2. Decentralized
“We do not rely on real world assets for collateral.”
Hylo is free of dependencies on:
Fiat-backed stablecoins (e.g., USDC)Real-world assets (RWA)Centralized custodians
Instead, it uses LSTs as fully on-chain collateral, effectively turning staking yield into a decentralized “bond” market for backing stable value and synthetic assets.
3. Permissionless
“Our protocol is autonomous and self-contained.”
Hylo does not require:
IntermediariesKYCAdministrative access
Anyone with a Solana wallet can mint hyUSD, leverage into xSOL, or earn passive yield, without ever trusting a third party. The system operates purely through immutable smart contracts.
4. Secure
“Stability is maintained with financially incentivized risk management mechanisms.”
Hylo prioritizes safety through
Conservative collateral ratiosReal-time value-at-risk (VaR) modelingSeparation of risk between stablecoin and leverage poolsNo reliance on AMMs or third-party price feeds
The result is a risk-contained, slippage-free liquidity model that can sustain itself even in volatile markets.
Design Philosophy
Hylo’s architecture is shaped by three foundational insights about DeFi’s challenges:
1. Stablecoins must be truly decentralized
Most DeFi stablecoins on Solana (e.g., USDC-backed) inherit counterparty and regulatory risk. Even MakerDAO’s DAI is increasingly reliant on real-world assets.
🔧 Hylo uses only on-chain LSTs to back its stablecoin, avoiding fiat and off-chain trust assumptions.
2. Leverage should match long-term conviction, not short-term speculation
Perpetual futures (perps) dominate leverage in DeFi, but are unsuitable for long-term investors due to:
Liquidation riskVolatile funding ratesPoor capital efficiency
🔧 xSOL offers durable, automated leverage with no funding or liquidation, aligning with HODL-style investing rather than trading.
3. Yield must be integrated, not wasted
Collateral in most DeFi protocols sits idle. Solana’s LSTs are natively yield-bearing, yet most protocols fail to harness this.
🔧 Hylo channels LST yield into:
Protocol revenuePeg maintenanceOptional yield vaults (hyUSD+)
Collateral Pool: A Basket of LSTs
At the heart of Hylo lies its Collateral Pool, made up of a diversified basket of LSTs on Solana:
mSOL (Marinade)JitoSOL (Jito Labs)bSOL (BlazeStake)(Others may be added via governance or protocol evolution)
This LST basket supports both hyUSD and xSOL and provides:
Yield-backed collateralizationCollateral diversity to mitigate validator or protocol-specific risksOn-chain composability for secure and efficient liquidity
Each LST accrues staking rewards, which are:
Used to offset systemic riskOffered as yield to hyUSD holders (if opted in)Partially redirected to protocol revenue
The protocol also uses dynamic weighting and accounting to ensure no single LST dominates the basket, enhancing resilience and decentralization.
Background Context
Hylo’s architecture stems from foundational research into three domains:
USDC, USDT, and similar assets dominate DeFi but pose regulatory, custodial, and censorship risks.Their off-chain nature violates DeFi’s core ethos.Hylo rejects this model entirely.
Projects like DAI, LUSD, and UXD attempt decentralization but face scalability and composability issues.Many use volatile collateral or rely heavily on oracles.Hylo offers a yield-native, oracle-free, collateral-efficient alternative.
Leverage in DeFi is designed for short-term trading.Long-term investors are underserved due to funding volatility and risk of liquidation.Hylo introduces xSOL to serve SOL believers with durable, passive exposure.
Core Products
Hylo introduces two flagship products: hyUSD, a decentralized stablecoin, and xSOL, a leveraged asset tracking SOL. These are built atop a carefully designed protocol that integrates staking yield, minimizes risk, and rewards users through the XP (Experience Points) System.
4.1 hyUSD — The Stablecoin
How Hylo Works?
hyUSD is a dollar-pegged stablecoin minted against a basket of liquid staking tokens (LSTs) on Solana, such as:
mSOL (Marinade)jitoSOL (Jito Labs)bSOL (BlazeStake)
Users deposit these LSTs into the protocol’s Collateral Pool to mint hyUSD. The system maintains full collateralization using the real-time protocol-defined value of each LST — not via external oracles.
Unlike USDC or other fiat-backed stablecoins, hyUSD is entirely on-chain, decentralized, and yield-native.
Collateral: A Yield-Backed Basket
The LST basket acts as both collateral and a yield engine. These LSTs accrue staking rewards, which flow into the protocol to:
Enhance peg stabilityEnable optional yield to hyUSD holders (via opt-in hyUSD+ vaults)Fund protocol revenue
This collateral system is diverse and risk-balanced, with weighting mechanisms to prevent overexposure to a single staking provider.
Stability Mechanism
Hylo ensures peg stability through
Minting and redemption logic: Users can always mint hyUSD against LSTs or redeem it for LSTs at fair protocol-defined values, ensuring zero-slippage liquidity.Value-at-Risk (VaR) framework: Prevents over-minting and ensures system solvency.Built-in incentives: Leverages yield, redemption pressure, and protocol fees to align behaviors and peg.
There is no dependency on oracles, external AMMs, or real-world price feeds, which is a major innovation in reducing systemic risk.
Use Cases
Stable Payments
hyUSD can be used for stable on-chain payments with no counterparty risk.Yield Farming
Users can opt into hyUSD+ vaults to earn yield from LST rewards, turning hyUSD into a yield-bearing stablecoin.Composability
As a Solana-native, fully collateralized stablecoin, hyUSD can be integrated intoLending markets (e.g., MarginFi, Solend)LP positions (e.g., Kamino vaults)DEX routing (via Jupiter, Orca)
4.2 xSOL — Leveraged SOL Exposure
Design and Mechanics
xSOL is a synthetic token that provides long-term leveraged exposure to SOL. Unlike perpetual futures or margin trading platforms, xSOL does not rely on funding rates, liquidation engines, or external price oracles.
It is minted by depositing hyUSD into the protocol, which simulates leverage by increasing SOL exposure through internal logic — backed by LSTs.
How It Achieves Leverage
When users mint xSOL, their deposited hyUSD is converted into additional LST collateral, increasing exposure to SOL while keeping the protocol overcollateralized.
Key features
Built-in leverage factor, determined by protocol parameters and LST performance.Staking rewards from the collateral continue to accrue in the background.No margin calls, liquidations, or perp-style volatility.
Target Users
Long-term SOL bullsDeFi users with high conviction in SOL but who want amplified exposure without constant managementUsers seeking non-custodial, passive leverage that compounds with staking yield
Risk Profile and Use Cases
While xSOL avoids the downsides of traditional leverage (like liquidation), it is still exposed to SOL’s price volatility. Users must understand that:
xSOL amplifies both gains and losses of SOL.It’s best suited for long-horizon strategies, not short-term trades.Redeemable back into hyUSD at protocol-defined fair value.
Use cases include
Portfolio exposure managementLeveraged DeFi farming (pair with hyUSD)Passive high-beta strategies for advanced investors
4.3 Hylo XP System — Incentives for Participation
Hylo includes a points-based incentive layer called the XP System — designed to reward early adopters and long-term protocol participants.
💠 What is Hylo XP?
XP stands for Experience PointsIt tracks user engagement across Hylo’s productsXP is non-transferable and tied to wallet activity
While not explicitly tied to a token yet, XP is widely anticipated to have future utility (e.g., token distribution, governance rights, exclusive access).
How to Earn XP
XP is earned by
Holding hyUSDHolding hyUSD+ (yield-bearing vault version)Holding xSOL
Each product offers a base payout rate, calculated based on:
Dollars heldTime held
For example
Holding $1,000 in hyUSD for 30 days earns more XP than holding $100.Yield vaults and leveraged products may receive higher multipliers due to added risk or protocol utility.

Strategic Advantages of Hylo
Hylo’s architecture is not just novel — it is strategically designed to eliminate key weaknesses in traditional and decentralized finance systems. Its core competitive edge lies in its self-contained design, innovative liquidity model, and advanced risk management, all implemented without relying on external oracles or AMMs.
5.1 Protocol Mechanics
(Minting, Redemption, Price Oracles)
Minting and Redemption Logic
Hylo uses internal protocol logic to determine minting and redemption values for both hyUSD and xSOL. These operations are slippage-free and oracle-independent, built to maintain user trust and capital efficiency even under volatility.
🔹 Minting hyUSD
Users deposit a basket of LSTs (e.g., mSOL, jitoSOL, bSOL).The protocol assigns internal values to these LSTs (based on exchange rates and protocol rules).In return, users receive hyUSD equal to a discounted value of their deposit (to ensure overcollateralization).
🔹 Redeeming hyUSD
Users can always redeem hyUSD for a proportional share of LSTs at fair protocol value, with no slippage.
🔹 Minting xSOL
Users deposit hyUSD, which the protocol uses to simulate a leveraged long SOL position by minting xSOL backed by excess LST exposure.
🔹 Redeeming xSOL
Users can burn xSOL to receive the protocol-defined equivalent value in hyUSD.
✅ Key Differentiator: All pricing is done internally, without dependence on external oracles like Pyth or Switchboard. This minimizes oracle attack vectors and censorship risk.
5.2 Liquidity Model
(Slippage-Free, AMM-Less)
Hylo offers a native, self-contained liquidity model, making it one of the few DeFi protocols that:
Does not rely on AMMs (e.g., Orca, Raydium).Offers slippage-free minting and redemption.Doesn’t require constant rebalancing or external LP incentives.
🔹 Key Characteristics
✅ Strategic Benefit: This model is immune to low-liquidity conditions, frontrunning, and MEV extraction, and offers a superior user experience for high-volume users.
5.3 Risk Management Mechanisms
(Incentives, Liquidations, Rebalancing)
Hylo employs a sophisticated, financially-incentivized risk management framework designed to maintain:
Peg stabilityCollateral integritySystem solvency
1. Overcollateralization with Yield
All minted hyUSD and xSOL are overcollateralized using yield-bearing LSTs.Yield helps offset risk and build buffer reserves, reducing reliance on liquidations or backstops.
2. Value-at-Risk (VaR) Modeling
The protocol uses Value-at-Risk analysis to determine safe collateralization thresholds.Mints and redemptions are restricted or adjusted dynamically based on real-time protocol health.If VaR increases (e.g., due to LST depeg), the system slows or halts issuance to protect solvency.
3. Risk Separation Between hyUSD and xSOL
The protocol segregates risk between
hyUSD (stablecoin layer)xSOL (leveraged exposure)
These systems share collateral infrastructure but do not cross-subsidize each other, preventing contagion between products.
4. Redemption Incentives
Users are incentivized (via arbitrage) to redeem hyUSD or xSOL when prices drift from fair value.Since redemptions always occur at internal value, arbitrageurs help restore peg without external coordination.
5. No Liquidations (for Users)
Unlike perps or CDP-based models (e.g., MakerDAO), Hylo has no forced liquidation mechanism.All systemic protection comes from conservative collateral rules, yield, and dynamic mint/redeem logic.
Hylo’s strategic design offers robust decentralization, composability, and risk isolation — core differentiators from legacy DeFi protocols. By rejecting the standard reliance on external liquidity, centralized oracles, and volatile leverage, Hylo positions itself as a next-generation financial primitive for a decentralized Solana economy.
Earn High Yield with hyUSD
Source: Earning Yield with hyUSD
What Is hyUSD? (Quick Recap)
hyUSD is Hylo’s decentralized stablecoin, backed 100% by a basket of Solana-based liquid staking tokens (LSTs). It is:
Pegged to $1Fully collateralized and oversecuredOracle-free and slippage-freeYield-native (thanks to LSTs)
But hyUSD is more than a passive stable asset — it offers active yield opportunities through the Stability Pool.
6.1 Earning Yield: The Stability Pool
What Is the Stability Pool?
The Stability Pool is Hylo’s central risk absorption and stabilization mechanism. It’s where users deposit hyUSD to:
Earn high protocol rewardsSecure the system against volatilityBackstop the protocol in rare adverse conditions
This is not just a yield farm — it’s a core part of Hylo’s design for sustainability and user-aligned incentives.
How Does It Work?
When you deposit your hyUSD into the Stability Pool, you are:
Providing protocol-layer insurance: If another user’s position becomes undercollateralized, a portion of your hyUSD may be used to absorb the bad debt.In return, you earnProtocol rewards (from leverage fees, redemption fees, and system revenue)Staking yield indirectly (since you’re backing the LST collateral)XP (Experience Points) — Hylo’s points system that may offer future benefits
💡 Stability Pool participants are first in line to receive protocol rewards, making this the highest-yielding use case for hyUSD holders.
Why Do Yields Tend to Be High?
Compensated Risk: You are taking on a calculated form of smart contract and systemic risk (e.g., in case of collateral shortfall). The protocol compensates you generously.LST Yield Flow: The LSTs backing hyUSD continue to generate staking yield, and a portion of that is recycled into rewards.No Middlemen or AMM dependency: All flows are internal to the protocol, making capital more efficient.
6.2 Tokenomics & Incentive Design
As of now, Hylo does not have a native token, but the XP system serves as a precursor to future token-based rewards or governance rights.
🔹 Incentive Alignment
6.3 Revenue Streams of the Protocol
Hylo is designed to generate sustainable, on-chain revenue, without inflationary token emissions or reliance on real-world assets.
🔹 Key Revenue Streams
Staking Yield from LSTsYield generated from collateral LSTsShared between protocol, Stability Pool participants, and yield vaultsMint/Redeem SpreadSmall spread fees collected when users mint or redeem hyUSD/xSOLDesigned to minimize slippage while supporting the systemLeverage Margin Fees (xSOL)Fees for minting xSOL capture economic upside from leverage demandVault Performance Fees (opt-in)hyUSD+ vault participants may pay a portion of yield as fees
These revenue streams enable the protocol to:
Pay out rewardsBuild reservesMaintain peg and systemic solvency
6.4 Sustainability of Peg and Leverage
Hylo’s design emphasizes long-term solvency and yield-based peg defense, rather than fragile arbitrage models or oracle-based interventions.
✅ Peg Sustainability via
Redemption arbitrage: Users can redeem hyUSD for LSTs, which restores peg if hyUSD trades below $1.Yield reserves: Accumulated staking rewards create protocol-level buffers.Stability Pool coverage: Helps absorb undercollateralized positions in black-swan scenarios.
✅ Leverage Sustainability via
No liquidations: xSOL doesn’t rely on liquidations, avoiding cascade effects.Yield-enhanced leverage: The underlying LSTs generate staking yield, easing the cost of leverage.VaR controls: Value-at-Risk models cap xSOL issuance to safe levels, preserving solvency.
Hylo’s Stability Pool is a powerful DeFi primitive that turns passive stablecoin holders into protocol co-insurers — rewarded with outsized returns for supporting systemic health. With no inflationary emissions, no reliance on liquidity mining, and native yield built into its collateral design, Hylo sets a new standard for sustainable stablecoin yield.
Security & Audits

7.2 Risk Mitigation Strategies
Hylo’s architecture is built from first principles to minimize systemic and technical risks. Below are its key mitigation measures:
A. No Oracle Dependency
Hylo does not use external price oracles (e.g., Pyth or Switchboard) to determine asset prices or trigger liquidations.
Why this matters
Prevents oracle manipulation (a common attack vector in DeFi)Removes single points of failureEnsures pricing remains stable, even during network congestion or downtime
Instead, Hylo uses internally computed exchange rates based on:
Known staking rates of LSTsProtocol-defined mathValue-at-Risk (VaR) controls
B. Depeg Protection & Stability Management
To protect against hyUSD depegging, Hylo employs a multi-layered defense system
Redemption ArbitrageIf hyUSD trades < $1, users are incentivized to redeem it 1:1 for LSTsArbitrageurs restore peg naturally through market incentives
2. Overcollateralization
All minted hyUSD is backed by more than $1 of LSTsDynamic collateral ratios maintain solvency during volatility
3. Stability Pool Backstop
Depositors absorb bad debt in exchange for high rewardsSystemic risk is distributed and financially incentivized
4. VaR Constraints
Protocol calculates real-time risk and halts minting or rebalancing if thresholds are exceeded
C. Leverage Control & xSOL Risk Separation
xSOL carries inherent risk due to its leveraged nature, but Hylo isolates and contains this risk via:
Separate collateral pools for hyUSD and xSOLCapped leverage ratios to prevent runaway exposureNo liquidations — avoids cascading failures and forced sellingStaking yield offset — reduces net leverage cost
7.3 Decentralization Tradeoffs
While Hylo maximizes on-chain autonomy, some early-stage decentralization tradeoffs are acknowledged:
Current Tradeoffs
Future Goals
Progressive decentralization via on-chain governanceCommunity whitelisting of new LSTs or assetsSmart contract immutability post-audit maturity
Hylo’s approach to security is rooted in proactive architecture design, not just reactive auditing. By eliminating oracles, ensuring transparent code, and isolating risk at every layer, it sets a high bar for systemic safety in Solana DeFi. Its public audit, zero-slippage internal mechanics, and decentralized peg mechanisms ensure user trust — even in volatile markets.
Comparison with alternatives
Hylo stands apart from traditional crypto-collateralized stablecoins like MakerDAO’s DAI by offering an entirely on-chain, oracle-free system backed solely by Solana liquid staking tokens (LSTs).
Unlike DAI, which increasingly relies on real-world assets and price oracles, Hylo uses LSTs to generate native staking yield, supports overcollateralization through internal math, and avoids liquidations altogether.
Its stablecoin, hyUSD, can be minted or redeemed without slippage, offering superior capital efficiency and decentralization.
Compared to UXD Protocol — another Solana-native stablecoin — Hylo offers a simpler, more sustainable architecture that doesn’t rely on complex delta-neutral positions or perpetual futures.
UXD depends on perpetual markets and oracles to maintain peg stability, exposing it to systemic risk. In contrast, Hylo maintains peg stability using collateral buffers, a Stability Pool, and yield-backed reserves, all while remaining oracle-independent and frictionless to interact with.
When stacked against Ethereum-based LST-backed protocols like Lybra and Ethena, Hylo delivers similar yield-bearing benefits but with stronger user control and a more modular design.
Where Lybra uses rebasing mechanics to distribute yield passively, Hylo allows users to opt in via hyUSD+, avoiding forced dilution.
It also ensures that redemptions remain slippage-free and transparent, and is positioned as the Solana-native alternative with similar economic advantages and fewer dependencies.
Hylo’s leverage token xSOL offers a major innovation over trading-centric protocols like Drift, MarginFi, or Kamino.
These platforms provide short-term leverage via perps or margin with liquidation risk and variable funding rates, whereas xSOL enables passive, long-term SOL exposure without liquidation, perpetual fees, or user intervention.
This makes Hylo uniquely suited for long-term DeFi users looking for stable value and sustainable leverage in one integrated platform.
Technical Addendum
Hylo’s architecture is built on a set of deterministic equations that govern how hyUSD and xSOL are minted and redeemed.
These formulas use internal valuations of liquid staking tokens (LSTs) and enforce strict collateralization ratios, allowing users to interact with the protocol in a slippage-free, oracle-independent manner.
For example, the amount of hyUSD minted is directly tied to the total USD value of LST collateral divided by a safety ratio, while the price of xSOL reflects the leveraged exposure to SOL over its supply. This transparent, math-based design makes user interactions predictable and secure.
To manage risk, Hylo implements a Value-at-Risk (VaR) framework, which calculates potential losses under extreme conditions (like an LST depeg).
This risk modeling is used to limit minting, cap leverage, and maintain collateral health, acting as a preemptive safeguard instead of relying on liquidations.
This ensures the system remains solvent and the hyUSD peg is protected, even in volatile market conditions.
Hylo is already integrated across the Solana ecosystem. Users can access it via popular wallets like Phantom, Backpack, and Solflare.
While Hylo’s minting and redemption are protocol-native and AMM-less, liquidity for hyUSD is beginning to form on platforms like Orca and Meteora. Additionally, hyUSD and xSOL are designed to be composable across Solana lending protocols, yield optimizers, and DEXs, enabling a wide range of DeFi strategies.
Though Hylo currently operates without a native governance token, it encourages early user engagement through the XP system, a points-based rewards model that may unlock future governance or token incentives.
The team has signaled a roadmap toward progressive decentralization, with governance of protocol parameters and collateral pool composition eventually migrating to a DAO.
In the meantime, the community is active across Telegram and X (Twitter), providing transparency and regular updates on development progress.

Strengths & Innovations
LST-Based Stability
hyUSD is fully backed by a basket of yield-bearing liquid staking tokens (LSTs) like mSOL, jitoSOL, and bSOL.This design captures on-chain staking yield and avoids exposure to centralized or fiat-backed collateral.
Zero Slippage Liquidity
All minting and redemption of hyUSD and xSOL occurs directly with the protocol at deterministic, formula-based prices.No AMMs or external markets are required, resulting in slippage-free user experience and predictable pricing.
No Reliance on Real-World Assets or Custodians
Hylo operates without fiat collateral (e.g., USDC) or real-world assets (RWAs).Eliminates custodial risk, regulatory exposure, and off-chain dependency, enhancing decentralization and trustlessness.
Oracle-Free Architecture
All valuations and system logic are computed internally, removing reliance on external price oracles.This protects against oracle manipulation, latency issues, and downtime risk.
Risk Management Highlights
Source: Additional Risk Management
Value-at-Risk (VaR) Modeling
Real-time risk metrics are used to cap new minting and rebalance collateral when systemic risk rises.Ensures protocol remains solvent even during market stress.
Isolated Risk Pools
hyUSD and xSOL are backed by the same LST basket but managed separately.This prevents contagion between stablecoin and leverage functions.
Automatic Rebalancing Triggers
If specific LSTs in the basket become risky or underperform, Hylo can rebalance collateral exposure based on protocol logic.Maintains overall health of the LST basket.
Emergency Circuit Breakers
Hylo includes automated fail-safes to pause operations like minting or redemption in extreme volatility, preventing collapse.
Mathematical Boundaries for Exposure
All key parameters — like maximum leverage, mint caps, and collateral weights — are defined via equations, not governance votes or manual intervention.
Challenges
1. Smart Contract Risk
As with all DeFi protocols, Hylo is exposed to potential vulnerabilities in smart contract code.While it has undergone audits (e.g., by OtterSec), there is always non-zero risk of bugs, exploits, or unintended behavior.Any fault in minting, redemption, or collateral accounting logic could impact user funds or protocol solvency.
2. Oracle Risk (Mitigated but Relevant)
Hylo avoids traditional external oracles, reducing direct dependency.However, internal logic still relies on predefined exchange rates and assumptions about LST performance.If LSTs (e.g., mSOL, jitoSOL) depeg or malfunction, the protocol must rely on internal safeguards like Value-at-Risk limits and Stability Pool buffers to maintain solvency.
3. Liquidity Fragmentation
Since Hylo uses a protocol-native, AMM-less model, most liquidity is concentrated within the system.External trading venues (like Orca or Jupiter) may face limited depth initially, causing fragmentation between primary and secondary markets.This could impact user experience or limit composability in early stages.
4. Regulatory Considerations
Hylo avoids fiat and RWA exposure, reducing regulatory entanglements.However, as a stablecoin and leverage provider, it may still face scrutiny around synthetic assets, stablecoin issuance, or decentralized governance in some jurisdictions.A lack of a governance token currently shields it, but future decentralization plans may require careful legal structuring.
5. Adoption Barriers
New users must understand complex concepts like LSTs, xSOL leverage, and Stability Pools.The absence of a governance token may reduce short-term user speculation or liquidity incentives.Competing protocols with higher liquidity, centralized backing, or token rewards may attract more users unless Hylo continues to scale awareness, utility, and integrations.
Roadmap & Future Outlook / Protocol Revenue
What’s Next for Hylo
Transition to DAO governance: Hylo plans to decentralize protocol control gradually — transferring collateral pool parameters, reward emissions, and risk settings to community governance structures. At launch, these remain managed by the founding team but will evolve into on-chain governance rocks over time.Expanded support for LST diversification: Adding new liquid staking token types (beyond mSOL, jitoSOL, bSOL) through controlled onboarding will deepen collateral resilience.Cross-chain composability: Future phases may enable cross-chain bridges or integrations with other LST ecosystems or chains to expand user access.Deeper integration into Solana DeFi stack: Expect synergies with lending protocols (Solend, MarginFi), LP strategies, DeFi dashboards, and yield aggregators to unlock broader utility.
Although the documentation doesn’t release a public timeline, community updates suggest these progressive upgrades are planned for the medium term.
Protocol Revenue Streams

Staking yield from LSTs: A core recurring income source — yield generated by the basket of collateral LSTs is shared between protocol revenue, Stability Pool rewards, and hyUSD+ vault holders.Mint & Redeem Spreads: Tiny fees applied on every minting or redemption of hyUSD and xSOL, designed to be minimal yet economically supportive of peg maintenance.Leverage issuance fees: Users paying to mint xSOL contribute to the protocol’s revenue via leverage spread mechanics.Vault performance fees (optional): Yield-bearing hyUSD+ vaults may carry performance fees to support sustainable operation.
According to recent analytics dashboards, Hylo has already earned tens of thousands of USD in protocol revenue
DeFi Landscape Outlook
As one of the only Solana-native, LST-backed stablecoin and synthetic leverage platforms, Hylo is well-positioned for long-term growth:
Growing demand for decentralized, oracle-free stablecoins: Hylo displaces fiat dependency in Solana DeFi by offering hyUSD — a truly on-chain stable value system.Natural fit for SOL-centric users: Enthusiasts seeking long-term leveraged exposure to SOL without liquidations or funding volatility may increasingly adopt xSOL.Ecosystem composability: hyUSD’s seamless integration into lending, liquidity pools, and yield strategies provides a compelling use case as Solana DeFi matures.XP-to-token potential: The XP points system primes the protocol for future token governance and utility rewards, boosting community engagement and growth incentives.
Strategic Summary
Roadmap Focus: Transition to on-chain governance, broader LST participation, cross-chain composability, and deeper integration into Solana DeFi stacks.Revenue Model: Based on yield from LST collateral, protocol fees on minting/redeeming, leverage issuance fees, and optional vault performance fees — currently generating early protocol income in the low-to-mid tens of thousands.Outlook: Positioned as a foundational protocol for decentralized stable value and long-term leverage built natively on Solana — Hylo stands to gain traction as user preference shifts away from centralized stablecoins and volatile perpetuals.
Conclusion
Hylo represents a major innovation in decentralized finance on Solana, delivering a protocol-native stablecoin (hyUSD) and long-term leverage product (xSOL) backed entirely by yield-bearing liquid staking tokens (LSTs).
It sets itself apart by eliminating reliance on fiat, centralized custodians, or oracles — creating a self-contained financial system with slippage-free operations, native staking yield, and robust risk management through internal logic and Value-at-Risk modeling.
The ideal users for Hylo include long-term SOL investors, DeFi builders, and liquidity providers seeking yield and composability.
For investors, xSOL offers durable leveraged exposure without funding fees or liquidation risk. Stablecoin users can opt into yield through the Stability Pool, earning rewards while strengthening the system. Builders benefit from hyUSD’s oracle-free pricing and protocol-native liquidity, making it easy to integrate into lending, swaps, and DeFi strategies.
Hylo’s XP-based rewards system incentivizes early participation and aligns users with the protocol’s long-term growth — priming it for future governance and potential token-based models.
Its roadmap focuses on decentralization, deeper ecosystem integration, and cross-chain reach, positioning it as a resilient cornerstone of Solana’s DeFi future.
Final verdict: Hylo is one of the most forward-thinking and technically sound protocols in the Solana ecosystem.
Its blend of LST-backed stability, composable leverage, oracle-free architecture, and real yield makes it not just a DeFi tool, but a foundational layer for decentralized, permissionless value creation on-chain.
FAQs
What is Hylo and why is it different from USDC or DAI?
Hylo is a decentralized finance protocol on Solana offering two main products: hyUSD, a stablecoin backed by liquid staking tokens (LSTs), and xSOL, a token providing long-term leveraged exposure to SOL. Unlike centralized stablecoins like USDC, hyUSD is fully on-chain and not backed by fiat or real-world assets.
Compared to DAI, Hylo removes oracle risk, doesn’t rely on overcollateralization with idle assets, and captures native staking yield from Solana — making it more decentralized, efficient, and yield-generating by design.
How can I earn yield with Hylo?
You can earn high yield by depositing hyUSD into the protocol’s Stability Pool. This helps backstop the system during volatility and, in return, you earn rewards from staking yield, leverage fees, and protocol revenues.
You can also opt in to hyUSD+, a vault that passively collects yield from the LST collateral. It’s a way to make your stablecoin work for you — without relying on farming or external liquidity pools.
Is Hylo safe to use?
Hylo has been audited by OtterSec, one of Solana’s top security firms, and implements robust risk management tools like Value-at-Risk (VaR) modeling, slippage-free mint/redeem logic, and isolation between stablecoin and leverage assets.
While no protocol is risk-free, Hylo avoids many common vulnerabilities by not relying on price oracles, centralized custodians, or AMMs — making it one of the most thoughtfully designed systems in Solana DeFi.
