Proposal to add wstETH

Proposal to add wstETH as an uncapped collateral to Interest Protocol.


wstETH is the wrapped version of stETH developed by Lido to facilitate DeFi transactions with the stETH token. Staked Ethereum is a rebase token, so it accrues staking rewards daily. This is a problem for protocols like Uniswap that require a constant known balance of tokens in their liquidity pools. If one were to provide liquidity in stETH in a Uniswap pool they risk losing out on a portion of their rewards.

“Wrapping” the stETH token in the Lido wrapper contract allows a holder to keep their amount of stETH fixed. The wrapper uses a share system to reflect staking rewards upon un-wrapping.

Due to the nature of wstETH it also comes with a tax benefit. Instead of paying income tax on the daily income from rebasing, a wstETH holder can consider the unwrapping of the token to claim rewards as capital gains. From a tax accounting perspective this greatly simplifies things.

The nature of wstETH makes it a highly secure asset, since it is effectively stETH (which is already used as collateral), simply in a wrapper that changes the reward distribution mechanism.

Hi hi - Could a moderator please remove the IP Improvement Proposals tag on this post? Thanks.


Bumping for visibility. Would be curious to see some more discussion on this, since I’m not personally up to speed on the differences of stETH vs wstETH as having different values as a collateral.
