What Are Liquid Staking Tokens (LSTs)? Understanding stETH and wstETH
Liquid Staking Tokens (LSTs) are the "receipts" you get when you stake ETH—they let you earn interest while still using the assets freely in DeFi. stETH and wstETH are two different representations of the same staked position: your stETH balance grows daily (like a savings account), while your wstETH balance stays fixed but each token becomes worth more (like a fixed-share fund). Let's break it down from the fundamentals to real-world use.

First, understand what problem "liquid staking" solves
Under Ethereum's Proof-of-Stake consensus, staking ETH to earn yield requires locking up at least 32 ETH, and withdrawals face a waiting period (roughly a few days to a week). That's too high a barrier for retail users, and once funds are locked, they're inaccessible.
Liquid staking protocols like Lido solve this: you deposit ETH, the protocol stakes it with node operators on your behalf, and gives you an equivalent amount of LST (liquid staking token). This LST is your "staking receipt"—you hold it, you earn staking rewards, and you can sell it at any time or use it as collateral in DeFi.
Checkpoint for understanding: grasp the core value of LSTs—earning staking yield without locking your capital.
The two ways LSTs track rewards
LSTs record interest in two different ways, which is key to understanding the difference between stETH and wstETH:
① Rebase (growing balance) The number of LSTs in your wallet automatically increases as interest accrues. For example, you have 1 today; a year later, you might have 1.04, while each token's value stays roughly 1:1 with ETH.
② Value-accumulating (fixed balance) The number of LSTs you hold never changes, but each token's value gradually rises over time. For instance, you exchange 1 ETH for 1 LST today; a year later, that 1 LST can be redeemed for 1.04 ETH.
Understanding stETH — the rebase token with a growing balance
stETH is the default LST issued by Lido, using a rebase mechanism. In simple terms:
- You stake 1 ETH, you receive 1 stETH.
- Every day, after Lido receives staking rewards, your stETH balance automatically increases (for example, tomorrow it might be 1.0001 stETH).
- The price of stETH tracks ETH closely (1 stETH ≈ 1 ETH).
What's the problem? Many DeFi protocols and cross-chain bridges don't support rebase tokens whose balances change on their own, because smart contracts typically treat token balances as fixed values. Depositing stETH directly into a lending protocol might lead to miscalculation of your collateral value with each balance update.
Checkpoint for understanding: know that stETH is the "auto-increasing quantity, price anchored near 1 ETH" token.
Understanding wstETH — the version with a rising price but fixed balance
wstETH (Wrapped stETH) is a wrapped version of stETH, built specifically to solve the problem that rebase causes in DeFi.
- Your wstETH balance never changes—deposit 100, and a year later you still hold 100.
- However, the amount of ETH each wstETH can redeem gradually increases (1 wstETH grows from being "worth 1.01 ETH" to "worth 1.05 ETH").
- Rewards are not distributed by minting more tokens; they make each token more valuable.
How to switch: At any time on the Lido website, you can wrap stETH into wstETH at the current exchange rate, not a 1:1 ratio. Most cross-chain bridges and DeFi protocols recommend only bridging/depositing wstETH, because a fixed balance is much easier for systems to handle.
Checkpoint for understanding: know that wstETH is the "fixed balance, rising unit value over time" version, the preferred format in DeFi scenarios.
Which one should you use? — Let the use case decide
| Use case | Recommended token | Reason |
|---|---|---|
| Long-term holding, minimal management | stETH | Balance grows automatically, simple and intuitive |
| Depositing into Aave or other lending protocols | wstETH | Fixed balance makes collateral ratio calculation easy |
| Bridging to L2s like Arbitrum or Base | wstETH | Most bridges have limited support for rebase tokens |
| Providing liquidity on Curve | stETH | Curve's stETH/ETH pool is a classic use case |
Checkpoint for understanding: be able to choose the appropriate version based on your actual use case, not just pick one at random.
Risk reminders
- stETH and ETH are not always 1:1: During the Terra collapse in May 2022, stETH on Curve briefly dropped to 0.935 ETH (a 6.5% deviation), triggering cascading liquidations. In extreme market stress, LSTs can temporarily depeg.
- Lido node operator concentration risk: Around 31% of staked ETH is concentrated in the Lido protocol. Issues with node operators (such as slashing penalties) could affect the entire LST ecosystem.
- Cross-chain bridge risk: When you bridge wstETH to another chain, you depend on the security of that bridge. If the bridge is attacked, your wstETH on the destination chain could become worthless IOUs.

Next steps
Open the Lido website, connect your wallet, and you'll see two entry points: „Stake ETH" and „Wrap". For now, just observe without acting: check how many stETH 1 wstETH currently converts to, and compare whether wstETH prices differ across chains like Arbitrum or Base. Once you understand the mechanics, you can decide whether to deposit ETH directly for stETH, or wrap your existing stETH into wstETH to use in DeFi.
