Liquid Staking Explained: How stETH and Friends Actually Work

Staking ETH the traditional way means running a validator with 32 ETH and accepting that your capital is tied up. Liquid staking removes both barriers: deposit any amount into a protocol, it stakes for you across professional validators, and you receive a liquid staking token (LST) — stETH being the best-known — that represents your stake and keeps earning rewards while remaining fully usable in DeFi.

The core mechanism

1. You deposit ETH into the protocol's contract.
2. The protocol distributes it to vetted node operators who run validators.
3. You receive an LST 1:1 against your deposit.
4. Staking rewards (consensus issuance + priority fees + MEV) flow back, growing your position — minus a protocol fee, commonly around 10% of rewards.
5. Exit anytime: swap the LST on a DEX instantly, or redeem through the protocol's withdrawal queue.

Rebasing vs. reward-bearing tokens

LSTs come in two accounting styles, and the difference matters for taxes and DeFi integrations:

• Rebasing (stETH): your token balance increases daily; one token stays ≈1 ETH.
• Reward-bearing (rETH, wstETH, cbETH): your balance stays fixed while each token's redemption value in ETH climbs over time.

Reward-bearing tokens integrate more cleanly with lending markets and LP pools, which is why wrapped stETH (wstETH) exists.

Why it took over DeFi

Liquid staking is consistently among the largest DeFi categories by TVL (see the live rankings) because it stacks yields: the base staking rate plus whatever you do with the LST — collateral for borrowing, liquidity in ETH/LST pools (minimal impermanent loss since the assets are correlated), or deposits into vault strategies.

The risks

• Smart-contract risk — the staking contract itself, plus every DeFi layer you stack on top.
• Depeg risk — LSTs can trade below their redemption value during panics; stETH dipped several percent in 2022 stress. If you never sell during the dip, this is mark-to-market pain, not realized loss — but leveraged LST positions get liquidated by exactly these dips.
• Slashing — misbehaving validators lose stake; losses are socialized across the pool. Rare, but nonzero.
• Centralization — one protocol controlling a huge share of staked ETH is a systemic concern for Ethereum itself; spreading stake across providers is healthier for everyone.

Restaking: the sequel

Restaking protocols (EigenLayer-style) let staked ETH also secure additional services for extra yield — and extra slashing conditions. It's the same trade as always: more yield, more stacked risk. Understand each layer before adding it.

Bottom line

For most ETH holders, liquid staking is the most sensible base yield in DeFi: real rewards from network issuance rather than token printing. Prefer the largest, longest-audited providers, mind depeg risk if you use leverage, and don't stack more layers than you can explain to someone else.
