Liquid Staking Derivatives in DeFi: Using Staked Tokens as Collateral
How tokens like stETH and rETH let your staked ETH keep earning while also backing a loan — and the risks that come with it.
Locking up ETH to stake it used to mean giving up access to that capital entirely. Liquid staking derivatives changed that by handing you a tradable token in return for your stake — one you can still put to work elsewhere in DeFi. This article explains how these tokens function as collateral and what to watch for before using them that way.
What Liquid Staking Derivatives Actually Are
When you stake ETH through a protocol like Lido or Rocket Pool, you receive a liquid staking token — stETH or rETH — that represents your staked position and keeps earning rewards in the background. Instead of sitting locked and idle, that token stays liquid: you can trade it, lend it, or supply it to a lending market. This is why liquid staking has grown into one of the largest categories in DeFi by value locked.
A liquid staking token lets your ETH do two jobs at once — earning staking rewards while also being usable as capital elsewhere in DeFi.
How Staked Tokens Work as DeFi Collateral
Platforms like Aave accept certain liquid staking tokens as collateral, letting you borrow against your staked position without unstaking it first. This means your ETH keeps earning staking rewards while also backing a loan or unlocking additional liquidity.
Depeg Risk to Understand First
Liquid staking tokens are designed to track the value of the underlying staked asset, but they trade on the open market and can briefly slip below parity during periods of stress. In leveraged positions, even a small depeg can trigger liquidations, so collateral value should never be assumed to move perfectly in step with the underlying asset.
Depegs are usually brief, but in a leveraged position even a small, temporary gap between a liquid staking token and its underlying asset can trigger forced liquidation.
Choosing Collateral: What Determines Liquid Staking Token Quality
Not every liquid staking token is treated the same by lending markets. Tokens with deeper liquidity and more predictable redemption paths, like stETH, tend to be accepted more widely as collateral than smaller or newer tokens. Before supplying any liquid staking token to a lending protocol, it’s worth checking its liquidity depth, redemption mechanism, and how the protocol’s oracle prices it, since these factors directly affect liquidation risk.
According to Ethereum.org, staking rewards on the network are earned continuously by validators, and liquid staking tokens are built to pass those rewards through to holders.
Conclusion
Liquid staking derivatives let you keep earning staking rewards while putting that same capital to work as collateral elsewhere in DeFi. That capital efficiency is powerful, but it comes with depeg and liquidation risks worth understanding first.
