Lido manages tens of billions of dollars in staked ETH\u200a\u2014\u200ayet most developers don\u2019t actually understand how it\u00a0works.<\/p>\n
At first glance, it seems simple: deposit ETH, receive stETH, earn\u00a0rewards.<\/p>\n
But under the hood, nothing is actually\u00a0simple.<\/p>\n
There is no single transaction that completes staking.
There is no direct path from deposit to validator.<\/p>\n
Instead, Lido operates as a multi-stage, oracle-driven system<\/strong>\u200a\u2014\u200awhere user actions only initiate<\/em> processes, and the system completes them asynchronously.<\/p>\n Understanding this architecture is the key to understanding how modern DeFi systems are really\u00a0built.<\/p>\n Most DeFi protocols are user-driven<\/strong>:<\/p>\n – You swap \u2192 state updates immediately But Lido doesn\u2019t work like\u00a0this.<\/p>\n In Lido:<\/p>\n – Deposits are delayed The system is not driven by users\u200a\u2014\u200ait is driven by\u00a0oracles.<\/p>\n This is what makes Lido fundamentally different.<\/p>\n When a user deposits ETH into\u00a0Lido:<\/p>\n – They immediately receive stETH Instead:<\/p>\n – ETH sits in a buffer In other words: deposit is decoupled from staking execution<\/strong><\/p>\n Here\u2019s the most important thing to understand:<\/p>\n In Lido, users don\u2019t execute the system\u200a\u2014\u200aoracles\u00a0do.<\/p>\n All critical updates happen through periodic oracle\u00a0reports:<\/p>\n – Validator balances This means:<\/p>\n Nothing is finalized at the moment of user interaction Withdrawal in Lido is not\u00a0instant.<\/p>\n It happens in three\u00a0stages:<\/p>\n request \u2192 finalize \u2192\u00a0claim<\/p>\n Between request and\u00a0claim:<\/p>\n – Validators must exit Withdrawal is not a function call\u200a\u2014\u200ait\u2019s a lifecycle<\/p>\n After breaking down the system, several important patterns\u00a0emerge:<\/p>\n Oracle-driven execution <\/em> Strong decoupling <\/em> Asynchronous settlement<\/em> Modular architecture <\/em> Lido is not just a staking protocol.<\/p>\n It is an asynchronous settlement system for Ethereum\u00a0staking<\/strong>.<\/p>\n This article only covers the high-level architecture.<\/p>\n I\u2019ve written a complete deep dive covering:<\/p>\n – Deposit flow Full documentation: GitHub: How Lido Works Under the Hood: A Deep Dive into Ethereum\u2019s Largest Staking Protocol<\/a> was originally published in Coinmonks<\/a> on Medium, where people are continuing the conversation by highlighting and responding to this story.<\/p>","protected":false},"excerpt":{"rendered":" Lido manages tens of billions of dollars in staked ETH\u200a\u2014\u200ayet most developers don\u2019t actually understand how it\u00a0works.

– You lend \u2192 balance updates instantly<\/p>\n
– Withdrawals are asynchronous
– Validator exits are decoupled from user\u00a0actions<\/p>\n1. Deposit Is Not What You\u00a0Think<\/em><\/strong><\/h3>\n
– But the ETH does NOT go into a validator<\/p>\n
– Deposits are executed later in batches
– Allocation is handled by StakingRouter<\/p>\n2. The Real Engine:\u00a0Oracle<\/em><\/strong><\/h3>\n
– Rewards
– Withdrawals
– System accounting<\/p>\n
Everything is settled later, in\u00a0batches<\/p>\n3. Withdrawal Is a Process, Not an\u00a0Action<\/em><\/strong><\/h3>\n
– ETH must return from the consensus layer
– Oracle must finalize the\u00a0request<\/p>\nKey Design\u00a0Insights<\/strong><\/h3>\n
<\/strong> State updates happen in cycles, not transactions<\/p>\n
<\/strong> Deposit \u2260 staking \u2260 exit \u2260 withdrawal<\/p>\n
<\/strong> Everything is eventually consistent<\/p>\n
<\/strong> Router coordinates, modules\u00a0execute<\/p>\nFull Technical Breakdown<\/strong><\/h3>\n
– Oracle system
– Withdrawal mechanism
– Fee model
– Exit bus\u00a0oracle<\/p>\n
