Choosing the Best Liquid Staking Token for Stacking Yield in DeFi

By Chanuka Geekiyanage Jul 13, 2026

A liquid staking token (LST) is what you receive when you stake ETH through a platform like Lido, Rocket Pool, or Coinbase. The real decision is not whether to use an LST. It's which LST to hold and how many layers of yield to stack on top of it before risk outweighs reward.

Pick the wrong token, and you can face depeg losses, liquidation risk, or exposure to a single point of failure. In May 2022, stETH traded as low as 0.94 ETH during the Terra collapse, a 6% discount that liquidated leveraged positions across Aave. This article breaks down how to compare LSTs, how many layers make sense, and when stacking stops being worth the risk.

Comparing the Top Liquid Staking Tokens

Not all LSTs carry the same risk profile, even though they all track ETH staking rewards. The three factors that matter most are decentralization, liquidity depth, and historical peg stability.

Token	Protocol	Decentralization	Liquidity (DEX depth)	Peg Stability
stETH	Lido	Lower (large validator concentration)	Highest, deepest Curve and Uniswap pools	Depegged briefly in 2022, recovered
rETH	Rocket Pool	Higher (permissionless node operators)	Moderate	Stable, rarely deviates past 0.5%
cbETH	Coinbase	Centralized (custodial)	Moderate	Stable but carries counterparty risk

Lido dominates TVL and liquidity, which makes stETH easiest to exit during stress. Rocket Pool trades some liquidity for a more decentralized validator set, which lowers correlated slashing risk. Coinbase's cbETH is easiest for beginners, but reintroduces the custodial risk that staking is supposed to remove.

How to Evaluate an LST Before Using It

Experienced DeFi users check four things before depositing into any LST, not just the advertised APY. Skipping this check is the most common mistake new stakers make.

Liquidity depth: Check the size of the stETH/ETH or rETH/ETH pool on Curve. Thin pools mean bigger slippage if you need to exit fast.
Validator decentralization: A protocol with a handful of large operators carries more correlated slashing risk than one with hundreds of independent nodes.
Audit history: Confirm the smart contracts have multiple independent audits and a live bug bounty, not just one report from launch.
Peg history: Look at how the token behaved during past market stress, since that tells you more than any current chart.

If a token fails two or more of these checks, treat it as higher risk regardless of its yield.

Building a Stacking Strategy Without Overextending

Stacking means using your LST again in a lending market or liquidity pool to earn a second or third yield source. Each layer adds return, but it also adds a point of failure that can wipe out gains from the layers below it. For details on how token mechanics change what you can safely stack, see the Rebasing vs Non-Rebasing Liquid Staking Tokens Explained guide.

A common three-layer stack looks like this: stake ETH on Lido for stETH, deposit stETH into Aave as collateral, then borrow USDC and deploy it into a stablecoin vault on Yearn. Each layer compounds yield, but a liquidation in the middle layer cancels out the top layer's gains. Most experienced users stop at three layers because gas costs and liquidation risk grow faster than the marginal yield past that point.

Risks and Tradeoffs of Stacking LSTs

Stacking multiplies both reward and risk, and the two do not scale evenly. A single weak layer can erase the benefit of the entire stack.

Depeg risk: If the LST trades below its underlying asset value, any position using it as collateral can face liquidation even though the staking rewards themselves are unaffected.
Smart contract risk: Every additional protocol in the stack is another codebase that could contain an exploit, and the risk compounds with each layer.
Liquidity risk: Exiting a three-layer stack during a market crash often costs more in slippage and gas than the yield earned from stacking in the first place.

Before treating any LST as collateral, review the Risks of Using Liquid Staking Tokens as Collateral to understand how liquidation thresholds actually work.

Decision Framework: Which LST and How Many Layers

The right choice depends on your risk tolerance, not just the highest advertised APY. Use this framework to match your setup to your experience level.

Choose stETH if: you need the deepest liquidity and want the easiest exit during volatility.
Choose rETH if: you prioritize decentralization and are comfortable with slightly lower liquidity.
Choose cbETH if: you want simplicity and already trust Coinbase as a custodian.

Stack one layer if: you are new to DeFi or want minimal liquidation exposure.
Stack two to three layers if you actively monitor collateral ratios and can react to market moves.
Avoid stacking past three layers if you cannot check your positions daily, since cascading liquidations move fast.

Common Mistakes to Avoid

Beginners and even intermediate users repeat the same errors when stacking LSTs. Avoiding these mistakes matters more than chasing extra yield.

Ignoring the LST's discount to its underlying asset when using it as loan collateral.
Stacking three or more layers without checking the liquidation threshold of each protocol involved.
Concentrating an entire portfolio in one LST issuer instead of splitting exposure across Lido, Rocket Pool, and others.

Best Platforms for Each Use Case

Different platforms fit different stacking goals. Matching the platform to your strategy reduces unnecessary risk.

Best for beginners: Coinbase's cbETH, since it requires no DeFi interaction beyond holding the token.
Best for liquidity and exit speed: Lido's stETH, thanks to its deep Curve and Uniswap pools.
Best for decentralization-focused users: Rocket Pool's rETH, due to its permissionless validator network.
Best for stacking into stablecoin yield: Aave paired with Yearn vaults, a combination widely used for the borrow-and-redeploy strategy.

Real Example: A Three-Layer Stack in Practice

Say you stake 10 ETH on Lido and receive 10 stETH. You deposit that stETH into Aave and borrow 12,000 USDC against it at a 70% loan-to-value ratio. You then deposit that USDC into a Yearn stablecoin vault, earning roughly 5% APY, on top of the 3-4% ETH staking yield and Aave's variable borrow cost. If ETH drops sharply and stETH's discount widens past your liquidation threshold, Aave liquidates your collateral before you can react, which is exactly what happened to overleveraged stETH positions in mid-2022.

Conclusion

Choosing an LST is a risk decision, not just a yield decision. stETH offers the best liquidity, rETH offers stronger decentralization, and cbETH offers simplicity at the cost of custodial trust. Stack conservatively, check liquidation thresholds at every layer, and treat any strategy beyond three layers as expert-only territory.

FAQs

1. Which liquid staking token is safest to use as collateral?

rETH is often considered safer for collateral due to Rocket Pool's decentralized validator set, though stETH's deeper liquidity makes it easier to exit during stress.

2. How many layers should a beginner stack?

Beginners should stick to one layer, simply holding the LST, until they understand liquidation mechanics and gas costs.

3. What causes an LST to depeg?

Depegs usually happen during mass sell-offs or liquidity crunches, as seen when stETH traded below ETH parity during the 2022 Terra collapse.

4. Is Coinbase's cbETH riskier than Lido's stETH?

cbETH carries custodial risk since Coinbase controls the underlying stake, while stETH is fully on-chain but has less decentralized validation.

5. When should someone avoid stacking altogether?

Avoid stacking if you cannot monitor your positions daily, since cascading liquidations across layers can happen within hours during a market crash.
