Staked Ether (stETH) is a type of cryptocurrency token that represents Ether (ETH) that has been locked or “staked” to help secure and run the Ethereum blockchain. It was created by Lido, a decentralized finance (DeFi) protocol, to make it easier for people to stake their ETH without locking it away completely.
stETH first launched in 2020, just before Ethereum transitioned from the old proof-of-work (PoW) system to the newer proof-of-stake (PoS) system. With stETH, you can deposit your ETH into a smart contract on the Lido platform and receive an equal amount of stETH in return.
This stETH can then be used just like regular ETH—it can be traded, borrowed, sold, or used in other DeFi services—while your original ETH continues to earn staking rewards in the background.
How stETH Works: Understanding the Basics of Staking
To fully understand stETH, you first need to know how staking works on Ethereum. When Ethereum switched to the proof-of-stake system in September 2022, it introduced a new way of validating transactions and securing the network.
In proof-of-stake, Ethereum holders (ETH owners) can become validators by locking up their ETH as a stake. This staked ETH acts as a security deposit—it encourages validators to behave honestly. If a validator acts dishonestly or breaks the rules, part or all of their staked ETH can be taken away (this is called “slashing”).
Validators help process transactions, create new blocks, and keep the blockchain secure. In return for their service, they earn rewards in ETH. However, while ETH is staked, it becomes illiquid—meaning you can’t use or trade it until it’s unstaked, which can take time.
Why stETH Was Created
Staking on Ethereum directly requires a minimum of 32 ETH, which many small investors simply don’t have. Even if you join a staking pool (where ETH from many users is combined), your ETH is still locked and can’t be used elsewhere.
That’s where Lido Finance and stETH come in.
With Lido, you can stake any amount of ETH—even less than 1 ETH—and receive stETH in return. This token represents your staked ETH but remains liquid. You can trade, lend, or use stETH in DeFi apps while still earning staking rewards on your underlying ETH.
Think of stETH like a derivative or a financial contract: it gives you access to the value of the original asset (ETH) without actually holding it directly.
How stETH Can Be Used
stETH is built to act like ETH in most cases, but it also unlocks new financial possibilities. Here are the main ways people use it:
- Liquidity Pools:
You can combine stETH with ETH in a liquidity pool, allowing people to swap between the two. This helps with unstaking, as you can exchange your stETH for ETH when needed—though the rates may vary. - Lending and Borrowing:
Some lending platforms like Aave allow you to use stETH as collateral. You can even “wrap” stETH—essentially pairing it with another token—to create even more complex financial tools. Keep in mind that this adds extra layers of risk. - Yield Farming:
You already earn yield (staking rewards) from your ETH. But with stETH, you can also re-invest it into platforms like Harvest Finance to earn additional returns—a process known as double-yield farming. - Derivatives and Options:
Lido and other platforms are working on advanced financial tools like put/call options and insurance derivatives, giving investors more ways to manage risk and profit from stETH.
What Happened When stETH and ETH Prices Went Out of Sync?
In early 2022, during a major crypto market downturn, stETH’s price dropped below the price of regular ETH. Although stETH is supposed to represent staked ETH, its price depends on market demand. This price drop caused panic among investors and added to the market chaos.
By late 2022, the prices of ETH and stETH became nearly equal again. It’s important to note that stETH was never meant to perfectly match ETH in price like a stablecoin matches the dollar. Instead, it’s a 1:1 token exchange—you get one stETH for each ETH you stake—not a guaranteed 1:1 value.
Some crypto analysts pointed out that stETH losing parity with ETH wasn’t like a stablecoin failure—because stETH isn’t a stablecoin. Instead, it’s designed to give stakers liquidity, and despite the price dip, it continued to work as intended by letting users trade their staked assets.
Can You Swap stETH for ETH?
Yes, you can exchange your stETH back into ETH through certain crypto exchanges or decentralized swap platforms. When you do this, you are basically unstaking your ETH—giving up your stETH and getting ETH you can immediately use.
This feature makes stETH extremely valuable for people who want to stake ETH but don’t want to lock it away for long periods.
Can You Sell stETH?
Absolutely. You can sell stETH just like other tokens, either to another user or on a cryptocurrency exchange. But keep in mind—by selling stETH, you’re also giving up your staked ETH and the rewards it would have earned. Also, the price might differ slightly from ETH depending on market conditions.
Final Thoughts: Why stETH Matters
stETH is a smart solution for Ethereum stakers who want both staking rewards and flexibility. It was introduced to solve the liquidity problem created when ETH was locked up for staking, especially after Ethereum’s switch to proof-of-stake.
By turning staked ETH into a usable token, stETH opens up new opportunities in DeFi—like lending, trading, and yield farming—without needing to unstake your ETH.
While price fluctuations can happen, the token continues to serve its main purpose: making Ethereum staking more accessible and liquid for everyday investors.
