Cours de Lido Wrapped stETH

Lido's wrapped stETH (wstETH) is stETH which is deposited into the stETH wrapper to create a new token called wstETH. You can wrap your stETH here. Wrapping stETH creates a DeFi-compatible version of the stETH token which allows for easier integrations with DeFi protocols including Uniswap and ARCx. Due to the nature of Lido, the amount of stETH on your balance is not constant - it changes daily as staking rewards come in. This is what's known as a rebasable token. In the case of stETH, this is reflected through a daily token balance change to reflect your earned rewards. This rebase works across integrated DeFi platforms like Curve and Yearn. This means that if you are to stake your stETH across these protocols to earn additional yields, you will continue to benefit from daily stETH staking rewards as well. UniSwap, 1inch and SushiSwap are not designed for rebasable tokens and as a result you risk losing out on a portion of your daily staking rewards through providing stETH as liquidity across these platforms. As some DeFi protocols - e.g. Uniswap - require a constant balance mechanism for tokens, Lido let's you "wrap" your stETH into wstETH to keeps your balance of stETH fixed. Instead of updating daily, wstETH uses an underlying share system to reflect your earned staking rewards. For Example:

• You wrap 100 stETH to 99.87 wstETH.
• You continue to earn rewards on your wstETH.
• When you unwrap your wstETH, you receive 101 stETH.

wstETH allows for seamless integrations across the DeFi space, facilitating the growth of stETH as a key piece of many unique Ethereum protocols. To wrap your ETH, visit stake.lido.fi/wrap.
