[PRESS RELEASE – San Francisco, United States, December 21st, 2025]
Self-Custody Wallet Eliminates Cross-Chain USDT Friction with Integrated Swaps, Bridges, and Anti-Scam Protection
Gem Wallet, a fully open-source self-custody wallet, today announced a comprehensive USDT infrastructure spanning 10+ blockchains, addressing the fragmented stablecoin experience that has plagued crypto users. With USDT now exceeding $140B in market capitalization, users face mounting challenges moving value across Tron (TRC20), Ethereum (ERC20), Solana, BNB Chain, TON, and other networks.
The Challenge: Cross-Chain USDT Functionality Remains Fragmented
Despite USDT’s ubiquity, sending stablecoins across chains remains costly, complex, and increasingly dangerous. Users must navigate:
Multiple wrapped versions of USDT across different chains
High gas fees on Ethereum (ERC20) vs. cheaper alternatives like Tron (TRC20)
Growing address poisoning attacks targeting USDT holders
Fragmented bridge and swap solutions
Complex fiat on/off-ramps with limited geographic coverage
The Solution: Unified USDT Infrastructure
Gem Wallet consolidates the entire USDT lifecycle into a single self-custody interface:
Security-First Approach
Address poisoning protection automatically flags suspicious transactions
Fully open-source codebase for complete transparency (https://github.com/gemwalletcom/)
Biometric authentication on mobile devices
User-controlled private keys (true self-custody)
True Multi-Chain USDT Support
Native support across 10+ blockchains including Tron, Ethereum, Solana, BNB Chain, and TON
Smart asset search automatically locates USDT balances across all supported chains
Unified interface eliminates chain-switching complexity
Cost-Optimized Transfers & Trading
Integration with 10+ decentralized swap providers (THORChain, Near Intents, Uniswap, Across Protocol)
User-controlled network fee settings
Automatic routing to lowest-cost swap options
USDT bridging with transparent fee comparison
Global Fiat Access
Seamless on/off-ramp through MoonPay, Paybis, and Transak
120+ countries supported
30+ payment methods including Apple Pay and Google Pay
Direct USDT purchases without intermediate steps
Why This Matters Now
“USDT has become the backbone of crypto liquidity, but users are forced to become chain experts just to move their stablecoins,” said Max Costa, Chief Marketing Officer at Gem Wallet. “We’re seeing hundreds of millions lost to address poisoning attacks, while users pay unnecessary fees bouncing between bridges and exchanges. Gem Wallet brings enterprise-grade USDT management to everyday users while maintaining complete self-custody.”
The address poisoning protection alone addresses a threat that has cost users over $100M in 2024, with attackers sending small amounts from similar-looking addresses to poison transaction histories.
