Liquid Staking Tokens: stETH, rETH, and cbETH Compared

Liquid staking tokens (LSTs) are tokenised representations of staked ETH that provide staking yield while remaining tradeable and usable as DeFi collateral — with Lido's stETH (largest, rebasing, ~33% of staked ETH), Rocket Pool's rETH (decentralised, non-rebasing), and Coinbase's cbETH (institutional, non-rebasing) being the three dominant options with distinct decentralisation and yield profiles.

Why Liquid Staking Tokens Exist

Ethereum staking requires 32 ETH minimum for direct validator operation (currently ~$100,000+), and staked ETH has a withdrawal queue that can take days to weeks during high unstaking demand. Liquid staking protocols solve both problems: they pool user ETH deposits, operate validators on their behalf, and issue liquid tokens that represent the staked position. These tokens can be traded immediately at any time, used as collateral in DeFi, and — critically — deposited into DeFi yield strategies that simultaneously earn staking yield plus DeFi yield. Liquid staking tokens have become DeFi's most important collateral asset class, with combined TVL exceeding $50B across the major protocols.

stETH (Lido Finance)

stETH is the largest liquid staking token by far, representing approximately 30–33% of all staked Ethereum — giving Lido a dominant and controversial position in Ethereum's validator set. When users deposit ETH into Lido, they receive stETH at a 1:1 ratio. As Ethereum staking rewards accumulate, stETH balances automatically increase (rebasing) — if you hold 10 stETH and the protocol earns 3.5% annual rewards, you will hold approximately 10.35 stETH after one year without any additional action. This rebasing mechanism makes stETH intuitive (your balance increases directly) but creates complications for DeFi integrations (contracts that receive rebasing tokens must handle the continuously changing balance).

wstETH (Wrapped stETH): To address DeFi compatibility issues, Lido introduced wstETH — a non-rebasing wrapper where the token price increases over time (reflecting accumulated rewards) instead of the balance. wstETH is used in most DeFi integrations — it is the primary Lido token used as collateral on Aave, Compound, and Morpho Blue, and as a Curve/Uniswap V3 liquidity pair base asset.

Yield: stETH/wstETH yields the net Ethereum staking APY minus Lido's 10% fee (split between node operators and the Lido DAO treasury). During periods of moderate staking activity, stETH yields approximately 3.2–4.0% APY. Lido's scale and validator diversity generally produce execution yields close to the Ethereum network average.

Lido's decentralisation concern: Lido's 30%+ share of staked Ethereum raises concerns about Ethereum network decentralisation — a single entity controlling that proportion of validators has meaningful influence over the chain. The Ethereum Foundation and core developers have repeatedly highlighted this as a systemic risk. Lido's governance has implemented measures (curated validator set, distributed among ~40 professional node operators) but the concentration concern remains a legitimate consideration when evaluating stETH vs more decentralised alternatives.

rETH (Rocket Pool)

Rocket Pool operates as a permissionless, decentralised liquid staking protocol — anyone can become a node operator by running a validator with 8 ETH of their own capital and 24 ETH of pooled user deposits, receiving rETH and additional RPL token rewards. The permissionless validator set (thousands of individual node operators rather than a whitelisted set) gives Rocket Pool meaningfully stronger decentralisation properties than Lido — making rETH the preferred choice for users who prioritise Ethereum decentralisation or are concerned about Lido's network concentration.

Non-rebasing mechanics: rETH does not rebase — instead, its exchange rate to ETH increases over time as rewards accumulate. 1 rETH becomes worth 1.05 ETH after a year at 5% yield, then 1.10 ETH the following year. This non-rebasing model is tax-advantaged in some jurisdictions (the exchange rate appreciation may be treated as capital gains on disposal rather than income on receipt) and is DeFi-compatible without requiring a wrapper token.

Yield: Rocket Pool node operators run their own validators and face direct slashing risk for their 8 ETH stake, which creates a stronger incentive for operational excellence than protocols where slashing risk is pooled. rETH yields are competitive with stETH, typically slightly higher due to Rocket Pool's node operators being more performance-focused, but fluctuate based on protocol-level economics including RPL staking requirements.

Liquidity limitation: rETH's liquidity depth is significantly smaller than stETH/wstETH — Rocket Pool's smaller TVL means rETH/ETH Uniswap V3 pools have less depth, potentially causing larger slippage on large rETH/ETH swaps. For large position sizes, stETH's superior secondary market liquidity is a practical advantage.

cbETH (Coinbase Wrapped Staked ETH)

cbETH is Coinbase's liquid staking token — issued when users stake ETH through Coinbase's retail staking product or Coinbase Prime (institutional). cbETH accumulates staking rewards as exchange rate appreciation (non-rebasing, similar to rETH mechanics). Coinbase charges a 25% fee on staking rewards — significantly higher than Lido (10%) or Rocket Pool (~15% effective), reducing cbETH's net yield relative to alternatives.

When cbETH makes sense: For Coinbase users who already have ETH on the platform and want the simplest possible staking experience without technical complexity, cbETH is entirely appropriate — the yield is lower than alternatives but the UX friction is near zero. For institutional clients using Coinbase Prime for custody, cbETH provides regulated, insured custody combined with staking yield — a combination that smaller protocols cannot match for compliance-sensitive institutions.

Risks: cbETH carries Coinbase counterparty risk beyond the smart contract risks of stETH and rETH. Regulatory action against Coinbase's staking product (the SEC's initial attempts to classify Coinbase staking as an unregistered securities offering demonstrated this risk), exchange insolvency, or operational failures are risks that do not apply to decentralised protocols in the same way.

DeFi Integration: Using LSTs as Collateral

The most powerful use case for LSTs: depositing wstETH or rETH as collateral on Aave or Morpho Blue to borrow USDC or ETH. This allows users to earn staking yield on their ETH while simultaneously accessing liquidity through borrowing — using borrowed stablecoins for expenses or investment without selling the underlying ETH position. The "stETH loop" strategy extends this: deposit wstETH as collateral, borrow ETH, swap borrowed ETH for stETH, deposit as additional collateral — increasing the staked ETH position and staking yield at the cost of leverage risk. Loop strategies amplify returns during normal market conditions but significantly increase liquidation risk if ETH price falls sharply or if the wstETH/ETH peg were to break.

Summary

Liquid staking tokens have transformed Ethereum staking from a locked, capital-inefficient activity into a composable building block of the DeFi yield stack. stETH (Lido) offers the deepest DeFi liquidity and lowest fees at the cost of network concentration concerns. rETH (Rocket Pool) prioritises decentralisation through permissionless node operation at slightly lower liquidity depth. cbETH (Coinbase) offers the simplest user experience and regulated institutional custody at the highest fee rate. The choice between them should be driven by individual priorities: DeFi yield maximisation (stETH/wstETH), Ethereum network health advocacy (rETH), or maximum operational simplicity and regulatory compliance (cbETH).
