Lido Review: Liquid Staking at Scale, and Its Costs

How stETH actually works

Ethereum staking has always had one awkward property: your ETH stops being usable. It secures the network and earns rewards, but you cannot sell it, cannot post it as collateral, and cannot react quickly if you change your mind. For a long-term holder that is tolerable. For anyone else it has been the main reason not to stake at all.

Lido's answer is a token. You deposit ETH into the protocol, which stakes it across a set of professional node operators, and you receive stETH in return. The stETH balance rebases upward as rewards accrue — your wallet simply shows more of it over time — and the token can be traded, lent or used as collateral while the underlying ETH remains staked.

The mechanism is elegant and the execution has been reliable. stETH is now accepted across most of DeFi, which means a staked position can simultaneously back a loan, sit in a liquidity pool or be sold instantly rather than waiting in Ethereum's exit queue.

There is no company holding your ETH. There is a smart contract, a DAO governing it, and a set of node operators running the validators. That is a genuinely different risk profile from a custodial exchange — not automatically safer, but different in ways worth understanding.

Lido rates in full

A 10% fee, in context

Lido charges a flat 10% of staking rewards. That is the entire fee structure: one number, published, applying to everyone, with no tiers and no conditions.

Set against exchange staking, the comparison is stark. Coinbase takes roughly 25% to 35% of gross rewards. Kraken's commission reaches 30% on some assets. Both are staking into the same Ethereum consensus mechanism and collecting the same underlying reward. The difference in what reaches you is entirely fee.

On a 20 ETH position at a 4% gross network rate, a 10% fee costs 0.08 ETH a year and a 33% commission costs 0.264 ETH. Over five years that gap approaches a full ETH — from identical exposure, identical protocol and identical risk to the underlying asset.

The concentration question

This is the most frequently raised criticism of Lido and it deserves a careful answer rather than either dismissal or alarm.

Lido controls a large share of all staked ETH — large enough that it has been an active, ongoing governance discussion within the Ethereum community about validator set decentralisation. The concern is not that Lido will misbehave. It is that a single protocol controlling a very large fraction of validators is a structural property nobody would choose to design deliberately.

For your individual position, this is not a direct risk in any immediate sense. Your stETH is not more likely to lose value because Lido is large. Lido operates through a distributed set of professional node operators rather than a single entity, and the protocol has governance mechanisms intended to manage exactly this.

Where it matters is if you stake partly because you care about Ethereum's health. In that case, where you stake is part of the decision, and Rocket Pool's permissionless node operator model is a deliberate alternative that trades a few tenths of a percentage point of yield for a meaningfully more distributed validator set. That is a reasonable trade and we would not argue against anyone making it.

When stETH trades below ETH

The second caveat is more immediately practical. stETH is a claim on staked ETH, not ETH itself, and the two can diverge.

In calm conditions they trade essentially at parity — arbitrageurs keep them aligned because stETH can be redeemed for ETH through the withdrawal process. During periods of stress, when many holders want out simultaneously and the Ethereum exit queue lengthens, stETH has traded at a discount. Sellers accept a small haircut to get liquidity now rather than wait.

Historically those discounts have been modest and temporary. They have also been real, and there is one situation where they matter a great deal: if you have posted stETH as collateral for a loan, a discount moves you towards liquidation on a position you thought was fully hedged. That is the specific scenario to understand before using stETH in a leveraged strategy.

For a straightforward hold-and-earn position, a temporary discount is an inconvenience rather than a loss — you simply do not sell into it.

Verdict

Lido scores 4.2 out of 5 and is the highest-scoring DeFi protocol in our database alongside Aave. The proposition is simple and it works: deposit ETH, receive stETH, earn 3.8% to 4.1% while the token stays tradable and usable as collateral across most of DeFi. The fee is a flat 10% — published, unconditional, and a third of what major exchanges charge for the same underlying reward. There is no custodian who can freeze your withdrawal, and the yield source is verifiable on-chain rather than taken on trust. Two things keep the score from going higher. Lido's share of staked ETH is large enough to be a live governance concern within the Ethereum community, which is a real consideration for anyone who stakes partly to support network health. And stETH is not ETH — during market stress it has traded at a discount, which matters most for anyone using it as loan collateral. For a long-term ETH holder comfortable with a wallet, this remains the best-shaped staking product available.

The facts, on one page

Licence and registration details are as published by the provider and, where possible, checked against the relevant public register. Registration of a firm does not mean a regulator has approved, endorsed or guaranteed its earn products — in the EU, MiCA authorisation specifically does not extend to crypto lending programmes. Verify current status on the FCA register or the relevant authority for your jurisdiction.

What Lido is not

It is not a regulated financial institution. It is an open protocol, not a licensed firm, and no authority supervises it. Its front-end restricts some jurisdictions while the underlying contracts remain permissionless. The European Commission has explicitly named DeFi and staking as gaps beyond MiCA's original scope, with a consultation running to 30 September 2026 — so there is no framework covering this today and none imminent.

It is also not a place to put ETH you might need to explain to a support desk. There is no support desk. A mistyped address, a malicious approval or a lost seed phrase is permanent, and no amount of protocol quality compensates for a user error.

For someone comfortable with those realities, Lido is the best-shaped ETH product available: close to the full network reward, a published flat fee, full liquidity retained, and a yield source you can verify yourself on-chain. For someone who is not, the honest answer is that paying a third of your rewards to an exchange is a legitimate price for account recovery, and nobody should be pushed into self-custody they are not ready for.
