stLINK vs wstLINK: What’s the Difference?

What is stLINK?

stLINK is the primary liquid staking token issued by stake.link when you deposit LINK into the protocol. It is a rebasing ERC-20 token — meaning your wallet balance increases automatically (approximately every two days) as Chainlink staking rewards accrue. You never need to claim or manually compound rewards; the balance simply grows.

stLINK maintains a 1:1 base peg with LINK. One stLINK always represents at least one LINK of underlying value, and over time represents more as rewards accumulate. The protocol holds all deposited LINK in official Chainlink staking pools (both the Community Pool and the Node Operator Pool) and rebases stLINK balances to reflect the aggregate yield.

Because stLINK rebases, it is ideal for users who want a straightforward staking experience: deposit LINK, hold stLINK, and watch the balance grow. It is also compatible with the Curve stLINK/LINK pool, where liquidity providers earn both trading fees and Chainlink staking rewards on their position.

What is wstLINK?

wstLINK (Wrapped stLINK) is a non-rebasing ERC-20 wrapper around stLINK. When you wrap stLINK into wstLINK, your balance stays constant — but each token represents a larger and larger amount of underlying LINK over time as the exchange rate compounds with accrued rewards. Instead of your balance growing, the value of each token grows.

This design solves a fundamental DeFi compatibility problem. Many lending markets, bridges, and DEXs struggle with rebasing tokens because balance changes break accounting assumptions — protocols need to know exactly how many tokens are held at any given moment. wstLINK gives them a stable, predictable unit while preserving full reward accrual.

wstLINK is the preferred form of staked LINK for DeFi interactions: it is accepted as collateral in Morpho lending markets, can be bridged cross-chain via Chainlink CCIP (to Arbitrum, Base, and Polygon), and is traded on Camelot DEX and Folks Finance. If you plan to put your staked LINK to work beyond simply holding, wstLINK is almost always the right token.

Key Differences

The fundamental distinction is how rewards are expressed. stLINK uses a rebasing mechanism — your balance increases approximately every two days. wstLINK uses an appreciation mechanism — your balance stays flat but the exchange rate between wstLINK and LINK increases over time. Both approaches deliver identical economic returns; they are two different representations of the same underlying staking position.

Neither token is strictly better than the other — they serve different purposes. The choice depends entirely on what you plan to do with your staked LINK. Holding passively? stLINK. Deploying into DeFi or bridging cross-chain? wstLINK.

When to Use Each

The table below summarizes the recommended token for each common use case. These recommendations reflect how each protocol actually handles the tokens — not opinion.

If you are primarily a long-term holder with no immediate plans to use DeFi, stLINK is the simplest and most intuitive choice — rewards compound automatically and are immediately visible in your wallet balance. If you are an active DeFi user who wants to earn additional yield on top of Chainlink staking rewards, wstLINK unlocks that entire ecosystem.

Many advanced users hold both: stLINK for the portion they want to keep liquid and visible, and wstLINK for the portion deployed as Morpho collateral or bridged to L2. You can always convert between them, so these are not permanent decisions.

How to Wrap / Unwrap

Converting between stLINK and wstLINK is instant and costs only gas — there are no protocol fees, no slippage, and no waiting period. The contracts handle the conversion at the current exchange rate and settle in the same transaction.

To wrap stLINK into wstLINK: the contract divides your stLINK amount by the current exchange rate to determine how many wstLINK to mint. To unwrap wstLINK back to stLINK: the contract multiplies your wstLINK amount by the current exchange rate. The math is always symmetric — you receive the economically equivalent amount in either direction.

When bridging via CCIP, you do not need to wrap manually first. The WrappedTokenBridge contract accepts stLINK on the source chain, wraps it to wstLINK atomically, and bridges the wstLINK to the destination chain in a single transaction. This makes the cross-chain experience seamless even if you hold stLINK.

The Exchange Rate

The wstLINK/stLINK exchange rate is the core mechanism that makes the non-rebasing wrapper work. It tracks exactly how many stLINK each wstLINK token represents, and it increases monotonically as rewards accrue.

Under normal conditions, the exchange rate never decreases. It can only increase (as rewards are distributed) or stay flat (if no rewards have accrued in a given period). The only scenario where the rate could theoretically decrease is a Chainlink staking slashing event — but as of writing, slashing has never occurred in 3+ years of stake.link protocol operation.

This one-way ratchet property is what makes wstLINK safe to hold long-term. Protocols that accept wstLINK as collateral or liquidity can rely on the token's value not declining due to rebase mechanics. Combined with zero slashing history and five independent security audits, wstLINK carries a well-established risk profile suitable for DeFi collateral use.

You can always view the live exchange rate on the stakedotlink.money dashboard — it reflects the current ratio between total staked LINK (including accumulated rewards) and total stLINK supply. As this rate rises, each wstLINK you hold silently becomes worth more LINK.
