What is stETH?
stETH (staked ETH) is a liquid staking token issued by Lido.fi, representing ether (ETH) that's been staked in Ethereum's proof-of-stake (PoS) consensus mechanism. Unlike traditional staking where assets are locked, stETH maintains liquidity while earning staking rewards.
How Lido.fi Enables Liquid Staking
Lido.fi provides liquidity solutions for staked PoS assets across five blockchains:
- Ethereum (~4% APY)
- Solana (~6% APY)
- Kusama (~12% APY)
- Polygon (~7% APY)
- Polkadot (~16% APY)
Technical Mechanism:
- Users deposit ETH into Lido's smart contract
- Receive stETH tokens 1:1 as redeemable certificates
- stETH accrues staking rewards automatically
- Tokens remain tradable on secondary markets

The stETH/ETH Peg Mechanism
Normally, arbitrage maintains the 1:1 peg:
- If stETH trades below ETH, buyers profit by redeeming through Lido
- If stETH trades above ETH, users mint new stETH by staking
Exception: The Ethereum Merge created temporary redemption limitations, preventing normal arbitrage until post-merge.
The Celsius Network Crisis
In June 2022, stETH experienced prolonged depegging due to:
- Celsius Network's hidden $2B shortfall from earlier hacks
- 73% of their ETH being locked in stETH/ETH2
- Forced stETH sell-off to meet customer redemptions
The AAVE Time Bomb
AAVE's stETH lending pool contained 1.4M stETH ($20B+) with peculiar characteristics:
- 0% APY
- 0% utilization rate
Funds used for recursive lending:
- Stake ETH → get stETH
- Deposit stETH → borrow ETH
- Repeat to build leverage
This created systemic risk of mass liquidations if stETH depegged significantly.
Arbitrage Opportunities
Current market conditions present unique chances:
- Buy stETH at discount (e.g., 0.5 ETH)
- Wait for Ethereum merge completion
- Redeem 1:1 for 100% profit
Risk Factors Considered:
| Risk Type | UST Comparison | stETH Reality |
|---|---|---|
| Backing | Algorithmic | 100% ETH |
| Redemption | Market-based | Post-merge |
| Volatility | High | Temporary |

FAQs
Q: Is stETH safer than UST?
A: Yes, stETH is fully backed by ETH rather than algorithmic formulas.
Q: When can stETH be redeemed 1:1?
A: Immediately after Ethereum completes its merge transition.
Q: What's the worst-case scenario?
A: Temporary price dislocation, but no permanent loss of peg.
Q: How does AAVE factor into this?
A: Their recursive lending positions could force sell stETH during depegs.
Q: Is now a good time to buy stETH?
A: For long-term holders, discounts represent attractive entry points.
Q: What happens if Lido fails?
A: stETH holders would still have claims on the underlying ETH.
Key Takeaways
- stETH depegging is temporary and merge-dependent
- Current discounts offer asymmetric return profiles
- Systemic risks exist but differ fundamentally from algorithmic failures
- Arbitrage opportunities require precise timing
- Always assess blockchain upgrade timelines
