If you are new to Base, you have probably seen tokens like cbETH or wstETH show up in a swap interface next to ETH. These are not just another pair of tokens. They represent staked ETH, and understanding what that means helps you tell the difference between a simple trade and a position with its own separate risks.
Swapping is a one time trade
When you swap on a decentralized exchange, you are exchanging one token for another at the current market rate, paying a small fee, and the transaction settles. Once it confirms, the trade is done. Nothing continues to happen in the background. If you swap USDC for ETH, you hold ETH, full stop.
Staking is different: it is a position, not a trade
Staking is how Ethereum's proof of stake network operates. Validators lock up ETH and use it to help propose and confirm blocks. In exchange for doing that work correctly, they earn rewards paid in ETH. If a validator behaves dishonestly or goes offline for extended periods, part of its stake can be slashed, meaning some ETH is forfeited as a penalty.
Running your own validator has historically required 32 ETH and reliable infrastructure, which is out of reach for most individual users. That is the problem liquid staking was built to solve.
What a liquid staking token is
Liquid staking lets you deposit any amount of ETH into a staking protocol, which pools it with deposits from many other users, runs validators on their behalf, and issues you a token that represents your share of the staked ETH plus the rewards it earns over time.
Two examples you will see on Base:
cbETH (Coinbase Wrapped Staked ETH). When you stake ETH through Coinbase, you receive cbETH, which is bridged to Base and tradable there. Its exchange rate against ETH increases gradually as staking rewards accrue, so cbETH is typically worth more than 1 ETH and the gap grows over time. You can verify the token contract on BaseScan.
wstETH (Wrapped staked ETH, from Lido). Lido is a staking protocol that issues stETH on Ethereum mainnet. wstETH is the wrapped, non-rebasing version designed for use in DeFi and on other networks, including Base, where you can confirm its contract on BaseScan. Like cbETH, its value relative to ETH rises as staking rewards accumulate.
In both cases, holding the token means holding a claim on staked ETH and its rewards, without running a validator yourself.
Why someone would swap into a liquid staking token
The appeal is that you keep exposure to ETH's price while the underlying stake earns rewards, and you are not locked out of using that value. Liquid staking tokens can typically still be swapped, used as collateral, or provided to a liquidity pool, unlike ETH staked directly and rigidly through a validator. That flexibility is the whole point of the "liquid" in liquid staking.
Risks that are specific to staking, not just to swapping
A liquid staking token is not the same risk profile as holding ETH outright. Before acquiring one, it is worth understanding what you are exposed to:
Smart contract and protocol risk. Your ETH is held and managed by the staking protocol's contracts. A bug or exploit in that protocol could affect the value of the token you hold, separate from anything happening to ETH itself.
Depeg risk. The token's price on the open market can temporarily trade below its underlying redemption value, especially during periods of high sell pressure or low liquidity. The token is still backed by staked ETH, but the market price you can actually sell at may not reflect that immediately.
Slashing risk. If the validators behind the protocol are penalized for misbehavior or downtime, that loss is generally distributed across all holders of the token, reducing its value slightly.
Withdrawal and redemption mechanics. Converting a liquid staking token back to plain ETH may go through the issuing platform (for example, Coinbase for cbETH) or through the protocol's own unstaking queue (for example, Lido for stETH), rather than always being instant. Swapping the token for ETH on a DEX is usually faster, but you get the market price, not necessarily the exact underlying value.
A practical way to think about it
If you swap USDC for ETH, you now hold ETH and your only exposure is ETH's price. If you swap USDC for cbETH or wstETH, you hold a claim on staked ETH plus accrued rewards, and you have added the protocol and market risks described above on top of ETH's price exposure. Neither choice is automatically right or wrong. They are simply different things, and it is worth knowing which one you are actually holding.
As always, verify any token contract address on BaseScan before trusting it, and never treat a similar looking ticker as proof that a token is the genuine, audited version of a liquid staking asset.
