Lido's wrapped stETH (wstETH) is a token created by depositing stETH into the stETH wrapper. It enables easier integrations with DeFi protocols like Uniswap and ARCx. The amount of stETH in your balance changes daily due to staking rewards, making it a rebasable token. This daily token balance change is reflected in integrated DeFi platforms such as Curve and Yearn. However, platforms like UniSwap, 1inch, and SushiSwap are not designed for rebasable tokens, which may result in a loss of daily staking rewards if stETH is provided as liquidity. To address this, Lido allows you to wrap your stETH into wstETH, which maintains a fixed balance of stETH. Instead of updating daily, wstETH uses an underlying share system to reflect earned staking rewards. Here's an example: You wrap 100 stETH into 99.87 wstETH, continue earning rewards on your wstETH, and when you unwrap it, you receive 101 stETH. wstETH enables seamless integrations across the DeFi space, contributing to the growth of stETH in various Ethereum protocols.
