💧Liquid Staking: stETH, rETH and the Risks of Re-Staking
Summary
Liquid Staking Tokens (LSTs) let you earn staking rewards while keeping liquidity to use capital in DeFi. They support $50B+ in TVL but introduce systemic risks the ecosystem is still learning to manage.
How an LST works
Deposit 1 ETH in Lido, receive 1 stETH — an ERC-20 token representing your staked ETH plus accumulated rewards. Lido distributes ETH across 30+ professional validators, charges 10% commission, delivers rest as daily rebase increasing your stETH balance. You can use stETH in Aave as collateral, swap to USDC on Curve, or provide stETH/ETH liquidity — all while earning ~3.5% staking APY. Rocket Pool (rETH) works similarly but decentralized, with node operators staking 8 ETH + 2.4 ETH in RPL as bond.
Depeg risk: stETH ≠ guaranteed ETH
1 stETH does NOT always equal 1 ETH in market. Normal conditions: 0.998-1.001 ratio, but stress events deviate: June 2022 (Celsius/3AC crisis) stETH fell to 0.94 ETH (~6% depeg), forcing mass Aave liquidations. Cause: fixed redemption ratio only valid post Shanghai/Capella upgrade (2023+); before that, unstaking took months. Today with withdrawals active, peg is more robust, but spot panics can still create 1-2% depeg. If you use stETH as leveraged collateral on Aave/Spark, a 3% depeg combined with ETH drawdown can liquidate you even while "still positive" in ETH terms.
Re-staking with EigenLayer: the new frontier
EigenLayer lets you re-stake your LST to secure additional services (oracles, bridges, DA layers) for extra rewards (LRTs like ezETH, weETH, rsETH). Aggregate APY: 5-12% real yield + airdrop farming. BUT: same ETH now backs multiple services — if ONE fails (slashing), you lose ETH proportionally. Opposite of diversification. LRTs add another smart contract risk layer over LSTs. Current rule: experiment with small amounts (<5% portfolio in LRTs), avoid as collateral until ecosystem matures (2-3 more years), and distrust >15% APY re-staking protocols — they farm emissions, not real yield.
Key takeaways
- LSTs (stETH, rETH) provide staking yield + liquidity to use in DeFi
- 1 stETH ≠ 1 ETH guaranteed — historical depegs up to 6% in crisis
- Lido dominates with ~30% of total ETH staking — centralization risk
- Re-staking (EigenLayer) compounds APYs but also slashing risks
- LRTs are experimental: <5% of portfolio until ecosystem matures
Pro tip
For conservative ETH yield: stETH or rETH direct = ~3.5% APY, low risk. To maximize: stack stETH→Aave→borrow USDC→stables farm = 8-12% real yield. For degen: LRTs + EigenLayer = 15%+ with cumulative slashing risk. Choose your position on the risk/reward curve consciously.
