Chainlink Staking shipped in production in late 2022, evolved into v0.2 in 2023, and reached v0.3 in 2024 — adding cross-chain participation and meaningful operator economics. Staking LINK directly into a Chainlink Staking pool is operationally simple but capital-illiquid: the LINK is locked for the duration of the staking commitment, and the holder gives up the ability to use the capital for anything else in the meantime. stake.link is the liquid-staking layer that sits on top of native Chainlink Staking and gives LINK holders a transferable receipt token (stLINK) that accrues staking rewards while remaining usable across DeFi. This article walks through how the protocol actually works in 2026.
Two clarifications upfront. First, stake.link is not a fork of Chainlink Staking — it is a smart-contract layer that participates in native Chainlink Staking on behalf of stLINK holders, batching their deposits and unstakes, routing through operator pools, and issuing the stLINK receipt token. The underlying staking economics, slashing parameters, and reward sources are Chainlink's; stake.link adds liquidity, composability, and operator routing. Second, 01node is one of the operators in the stake.link curated set — we have been part of the protocol since launch. We will return to operator selection later in the piece.
What you actually deposit, and what you get back
The user-facing flow is one transaction. A LINK holder approves the stake.link staking contract for the amount they want to stake, then calls the deposit function. The contract pulls the LINK, queues it for entry into native Chainlink Staking through one of the operator pools, and mints stLINK to the user at the prevailing exchange rate. The exchange rate at any given moment is the protocol's total backing LINK divided by total stLINK in circulation; it is greater than 1.0 by an amount that reflects accumulated staking rewards since launch.
stLINK is an ERC-20 token. It is not a rebasing token — the balance in your wallet does not change as rewards accrue. Instead, the exchange rate between stLINK and LINK rises over time as the underlying staked LINK earns rewards. One stLINK at launch redeemed for one LINK; one stLINK in mid-2026 redeems for somewhat more than one LINK, with the exact premium reflecting the time-weighted average reward rate net of the protocol fee. This accumulating-value design is the same model used by rETH (Rocket Pool) and several other liquid staking tokens; it integrates more cleanly with DeFi lending and AMM pools than a rebasing model does.
Withdrawing is asymmetric. Deposits are immediate if there is capacity in the operator pools. Withdrawals queue against the Chainlink Staking unstake window — currently 28 days on v0.3 — because the underlying LINK has to actually exit native Chainlink Staking before stake.link can release it to the user. In practice, the protocol maintains a small liquid buffer that handles same-day exit for small amounts, and queues larger amounts through the unstake window. For institutional-scale exits, the 28-day expectation is the binding number.
The pool architecture: Priority, Community, Operator
stake.link routes LINK through three structured pools, each with a distinct role in the protocol's economic and operational design.
- The Priority Pool is the entry queue. When native Chainlink Staking pool capacity is constrained (which it has been at multiple points since v0.2 launched), deposited LINK enters the Priority Pool and earns rewards based on a fair queue position rather than first-come-first-served racing. This was an explicit design decision after the chaos of the v0.1 launch, where deposits filled the pool in seconds and most users got nothing. Priority Pool position is determined by stake size, time in queue, and other parameters the protocol governance has tuned across versions. - The Community Pool holds the LINK that has successfully entered native Chainlink Staking through the community-stake side of the protocol. This is the larger of the two stakeable sides and represents the majority of stake.link's TVL. Community Pool LINK earns the community-stake reward rate, which is lower than the operator-stake rate but available to anyone. - The Operator Pool holds the LINK delegated to specific Chainlink node operators (us, plus the other 14 operators in the stake.link network at time of writing). Operator-pool LINK earns the operator reward rate, which is higher than the community rate but is subject to the operator-side slashing rules. stake.link's design is what allows ordinary stLINK holders to participate in operator-side rewards indirectly — the protocol's exchange rate aggregates the rewards from both pools.
The split between Community and Operator pools is one of the protocol-economic choices that makes stake.link materially more interesting than a single-pool liquid staking design. It captures the spread between the two Chainlink reward rates in a way that a one-side-only protocol cannot.
stLINK in DeFi: where the composability shows up
The reason to hold stLINK rather than to stake LINK directly is that stLINK remains usable in DeFi. The composability matters most in three contexts.
First, lending markets. stLINK can be supplied as collateral on Aave, Spark, and several Chainlink-ecosystem lending protocols. The holder earns Chainlink staking rewards through the accruing stLINK exchange rate, plus lending yield from supplying the token, plus the option to borrow against the collateral for additional capital efficiency. The blended yield on an stLINK position can meaningfully exceed pure LINK staking, with the trade-off being smart-contract risk across the additional protocol layer.
Second, AMM liquidity pools. stLINK / LINK and stLINK / ETH pools on Uniswap V4 and Curve provide swap liquidity for users who want to enter or exit stLINK outside the 28-day withdrawal queue. The pools price stLINK against the underlying LINK with a tight spread that reflects the unstake-window time-value-of-money and the protocol's accumulated reward rate. LPs earn swap fees, with the trade-off being impermanent loss exposure during periods when the stLINK/LINK ratio moves rapidly.
Third, structured yield products. Several DeFi protocols accept stLINK as the underlying for yield-bearing strategies, automated re-staking flows, and leveraged staking positions. These add additional smart-contract risk layers and are not appropriate for every holder; they are the most extreme expression of the capital-efficiency thesis that drove liquid staking in the first place.
How operator selection actually works
Inside the Operator Pool, stake.link does not pick operators arbitrarily. The protocol delegates to a curated set of Chainlink node operators selected on the basis of operational history, slashing record, node performance, geographic and infrastructure diversity, and community standing. The operator set is updated through stake.link governance as the protocol evolves; the current set is published in the protocol documentation and verifiable on-chain.
Each operator runs Chainlink oracle infrastructure that secures the v0.3 staking pool. Operator-side rewards are higher than community-side because operators are also providing the underlying oracle work that Chainlink Staking is designed to compensate; operator-side slashing risk is also higher because operators can be slashed for the oracle-protocol-level failures that pure community stakers cannot.
For stLINK holders, the practical implication is that the safety of the operator-pool portion of their exchange rate depends on the operational discipline of the specific operators in the curated set. An operator with sloppy slashing protection, weak monitoring, or shared infrastructure with cloud-correlated failure modes is a real risk to the protocol's total reward rate. The trust that stLINK holders place in stake.link is, in large part, trust in stake.link's operator selection.
01node has been a Chainlink Node Operator since 2020 and one of the operators in the stake.link curated set since the v0.2 integration. The infrastructure backing that position is the bare-metal architecture we describe at /blog/why-bare-metal-matters and /blog/on-validator-setup-seven-years-later: dual-DC Tier III in Bucharest, YubiHSM-backed keys, AS41536 with our own BGP, eBPF-based monitoring, and a six-year zero-slashing record.
Where the slashing surface actually sits
There are three distinct slashing-or-loss surfaces in an stLINK position. Understanding all three is the difference between a holder who knows what they are exposed to and a holder who is hoping for the best.
The first is Chainlink Staking protocol-level slashing. v0.3 has explicit slashing parameters for operator-side participation; community-side stakers face proportional impact if the pool's underlying performance is degraded. The slashing parameters and the events that trigger them are documented in the Chainlink Staking documentation; stake.link inherits these parameters directly.
The second is stake.link smart-contract risk. The protocol's contracts have been audited by Trail of Bits, OpenZeppelin, and others; the audits are public and the major findings have been remediated. That said, smart-contract risk is never zero — a previously undiscovered bug in the deposit, withdraw, or operator-routing logic could in principle affect stLINK holders. The protocol's governance has the ability to upgrade contracts; the upgrade authority and timelocks are part of the published architecture.
The third is DeFi-integration risk when stLINK is used as collateral or in AMM pools. This risk is not inherent to stake.link or to Chainlink Staking — it is the risk of the specific lending market or AMM the holder chose to use. It is also the most underappreciated of the three, because it compounds with the other two: a slashing event on Chainlink Staking that materially drops the stLINK exchange rate can cascade into liquidations across the lending markets where stLINK is deposited as collateral.
Holders concerned about slashing surface should think about all three layers explicitly when sizing their stLINK position. Holders who are using stLINK primarily as a liquidity-preserving wrapper for LINK staking, with no DeFi integration on top, face only the first two surfaces and are reasonably insulated from the third.
The state of the protocol in 2026
stake.link's TVL has grown steadily through the v0.2 and v0.3 cycles. The current public metrics show ~6.5M LINK staked through the protocol across the 15 operators in the curated set, distributed between the Community and Operator pools, with stLINK in circulation backed by that staked LINK plus accumulated rewards. The protocol fee is a small percentage of the rewards generated, which funds protocol development, the operator network, and the security budget.
Operationally, the protocol has handled multiple Chainlink Staking version transitions without disruption to stLINK holders — the upgrade flow is designed so that the underlying staking pool can change without invalidating the stLINK token. v0.3's cross-chain participation expanded the set of networks stake.link can route through; future Chainlink Staking versions are expected to continue this trajectory.
For new entrants in 2026, the practical question is no longer "should I use a liquid staking layer or stake LINK directly". The capital efficiency case for liquid staking has been settled across multiple cycles. The practical question is "which liquid staking layer", and the answer depends on operator transparency, audit history, DeFi integration depth, and the holder's own comfort with the specific protocol architecture. stake.link is the dominant LINK liquid staking layer by TVL and by operator quality; the alternatives are smaller and operationally less proven.
How 01node is positioned
We have been a Chainlink Node Operator since September 2020 and a Chainlink Channel Partner since the channel programme launched. We were part of the stake.link operator set from the v0.2 integration onwards and remain one of the operators in the curated set. The infrastructure backing our stake.link participation is identical to the infrastructure backing every other chain we validate — AS41536 in Bucharest, dual-DC Tier III, YubiHSM-backed keys, Web3Signer slashing protection on the Ethereum-resident contracts, AMD EPYC compute, ECC RAM, enterprise NVMe storage. The architecture is documented in detail at /blog/on-validator-setup-seven-years-later.
For LINK holders evaluating stLINK, we would suggest the following structural framing. First, understand which of the three slashing surfaces you are actually exposed to. Second, look at the operator set and the operator transparency — operators that publish their architecture, hardware, and compliance posture are operators that have made the operational commitment that justifies trusting the slashing surface they introduce. Third, size the position in proportion to your understanding of the smart-contract risk; do not treat liquid staking as a free yield enhancement. Our compliance posture is at /security; the on-chain receipts for our Chainlink Node Operator status are at /operator-credentials; the previous coverage of our stake.link partnership is at /blog/stakelink-chainlink-liquid-staking and /blog/01node-x-stake-link-strategic-partnership-for-chainlink-link-liquid-staking.
