Staking is a key mechanism that aims to bring a new layer of cryptoeconomic security to Chainlink.
Staking provides Chainlink ecosystem participants with the opportunity to earn rewards for increasing the security guarantees and user assurances of oracle services by backing them with staked LINK tokens. Chainlink Staking initially launched with v0.1 and is evolving with the upcoming v0.2 upgrade.

Frequently asked questions
Staking Overview
Staking Overview
What is the v0.2 upgrade to Chainlink Staking?
What is the v0.2 upgrade to Chainlink Staking?
Building upon the foundation established by the Chainlink Staking v0.1 release in December 2022, the v0.2 upgrade expands Chainlink Staking into a fully modular, extensible, and upgradable Staking platform. This upgrade focuses on the following key goals:
Greater flexibility for Community and Node Operator Stakers by introducing a new unbonding mechanism for withdrawing staked LINK from Staking v0.2.
Improved security guarantees for Chainlink oracle services secured by staking through the slashing of staked LINK from Node Operator Stakers.
Seamless future upgradability through the creation of a modular architecture that can support future improvements and addition, such as the expansion to more services.
Dynamic rewards mechanism that supports new sources of staking rewards in the future, such as user fees, particularly as staking expands to secure more services.
Staking v0.2 will involve a three-phase launch sequence.
Phase 1: Priority Migration
On November 28, 2023 at 12PM ET, v0.1 stakers have the exclusive opportunity to migrate their v0.1 stake and accrued LINK rewards to v0.2 or withdraw. The Priority Migration period will last for nine days, where v0.1 stakers can choose to migrate all or a portion of their v0.1 stake and rewards. If choosing to migrate a portion, then all non-migrated v0.1 stake or rewards will be automatically withdrawn. If a v0.1 staker takes no action, then their staked LINK and rewards will remain in v0.1 and no longer earn rewards.
Given that the v0.2 pool is larger than the v0.1 pool, and accounting for accrued rewards, v0.1 stakers have guaranteed access to v0.2 if they participate in the Priority Migration phase. Once the Priority Migration period ends, v0.1 stakers can still migrate or withdraw during Early Access and General Access; however, entry to v0.2 will not be guaranteed due to the capped pool size.
Note that v0.1 stakers are only eligible to migrate an amount equal to the sum of their staked LINK and any LINK rewards accumulated in v0.1 during the Priority Migration phase. v0.1 stakers who want to stake more LINK, up to the per-address cap, have the opportunity during later entry periods.
The Priority Migration period for v0.1 stakers was extended to nine days to provide additional time for existing v0.1 stakers to migrate their staked LINK and rewards to v0.2.
Phase 2: Early Access
After the Priority Migration period ends, on December 7, 2023 at 12PM ET, LINK token holders who meet at least one predefined criterion on the updated Early Access Eligibility List will have the opportunity to stake LINK in v0.2 up to a total of 15,000 LINK. Similar to the Early Access period during v0.1 launch, being on the eligibility list provides an opportunity to stake in v0.2 but does not serve as a guarantee of entry given the capped pool size. The Early Access entry period will last for four days.
Similar to Priority Migration, the Early Access period for v0.1 stakers was extended to four days to provide additional time for eligible stakers to participate in Staking v0.2.
After Early Access ends, on December 11, 2023 at 12PM ET, the v0.2 staking pool will open to General Access, at which point anyone will have the chance to stake up to the per-wallet maximum, provided that the v0.2 pool has not yet been filled.
Chainlink ecosystem participants, including token holders and node operators, can stake their LINK and participate in securing the Chainlink Network. Learn more about the v0.2 upgrade to Chainlink Staking in the following blog Introducing the Chainlink Staking Platform.
How much LINK can I stake?
How much LINK can I stake?
Community Stakers can stake a minimum of 1 LINK and up to a maximum of up to 15,000 LINK during Early Access and General Access on a per-address basis. Note that entry to v0.2 during these phases is not guaranteed due to the capped pool size. Node Operator Stakers can stake a minimum of 1,000 LINK and a maximum of up to 75,000 LINK.
Will my staked LINK in v0.1 be automatically migrated to v0.2?
Will my staked LINK in v0.1 be automatically migrated to v0.2?
No, the smart contracts for Chainlink Staking v0.1 and v0.2 are non-custodial by design, meaning no entity other than the staker themselves can withdraw or migrate their staked LINK from one version to the next. v0.1 stakers will need to provide explicit approval to migrate their staked LINK and/or rewards to v0.2 by signing an onchain transaction.
Staking v0.2 features an expanded total pool size of 45,000,000 LINK to increase the accessibility of Chainlink Staking to a more diverse audience of LINK token holders. The pool size represents an 80% increase from the pool cap of v0.1 and would account for over 8% of the current circulating supply of LINK. The capped 45,000,000 LINK pool will consist of a 40,875,000 LINK allotment for community members, with the remainder allocated to Chainlink node operators currently servicing Chainlink Data Feeds.
The expanded pool size of v0.2 reflects the goal of increasing the security guarantees and user assurances provided around in-scope oracle services over time, while maintaining a security-conscious approach to the expansion of Staking. Furthermore, the capped pool size also supports the network’s economic sustainability before new sources of staking rewards, such as user fee rewards, are made available to LINK stakers. Over time, the pool size cap is expected to increase, particularly as Chainlink Staking continues to evolve to support additional Chainlink services.
The reward rate calculation for v0.2 has been rearchitected to incentivize a fully-filled Staking pool and improve support for new sources of staking rewards in the future (e.g., user fees). While v0.1 has a fixed reward rate (i.e., a single rate for all Community Stakers regardless of pool fill rate), v0.2 introduces a variable reward rate.
The variable reward rate results from the fact that a fixed amount of rewards in total are made available to the staking pool per unit of time, regardless of how much aggregate LINK is staked in the pool. Therefore, stakers won’t have a fixed reward rate, but rather the rate of reward will be variable based on how full the pool is and the amount of rewards made available per unit of time (creating an effective floor rate at a specific pool size limit and fixed reward amount). If the pool isn’t full, the same amount of rewards will be made available proportionately to a reduced number of stakers, resulting in a higher reward rate, and vice versa.
This change in reward rate calculation was required given that the source of rewards in Chainlink Staking in the future is expected to increasingly shift towards being derived from external sources of rewards (e.g. user fees), which may be a variable amount.
Assuming an entirely filled community pool, the community stake portion of the v0.2 pool at launch will feature a base floor reward rate of 4.5% per year in LINK for helping secure the Chainlink Network. From those annualized rewards, 4% of Community Staker rewards will be automatically directed to Node Operator Stakers as a Delegation Reward. The result is an effective base floor reward rate of 4.32% on an annualized basis for Community Stakers in v0.2 at launch. As noted previously, the actual amount of rewards made available to stakers will depend on how full the pool is, with a higher effective reward rate if the pool is less than full.
This base floor reward rate was determined based on the need to balance the network’s economic sustainability over time, while ensuring stakers are fairly rewarded for their work securing the network. It is expected that emissions-based rewards will trend eventually toward zero as external sources of staking rewards, such as user fees, grow to sustainably support the network’s cryptoeconomic security staking layer.
The node operator stake portion of the v0.2 pool will feature the same 4.5% base floor reward rate but will be supplemented by Delegation Rewards from Community Stakers and made available to Node Operator Stakers proportionally based on the amount each operator stakes.
v0.1 stakers are only eligible to migrate an amount equal to the sum of their staked LINK and any LINK rewards accumulated in v0.1 during the Priority Migration phase. v0.1 stakers who want to stake more LINK have the opportunity during later entry periods, provided the pool has not yet been filled.
Note that all existing v0.1 stakers will be automatically eligible for Early Access due to their participation in prior versions of Chainlink Staking, where additional LINK can be staked up to the new per-staker maximum of 15,000 LINK. For example, a v0.1 staker who migrates 7,000 staked LINK and 300 LINK in earned rewards to v0.2 then has the opportunity to stake up to an additional 7,700 LINK for a total of 15,000 LINK during the Early or General Access periods.
Can I stake more LINK on the same address?
Can I stake more LINK on the same address?
During the Priority Migration phase, v0.1 stakers are only eligible to migrate an amount equal to the sum of their staked LINK and any LINK rewards accumulated in v0.1. Those who migrate their v0.1 stake during Priority Migration and want to stake more LINK have the opportunity during later entry periods, provided the pool has not yet been filled.
Additional LINK can be staked by v0.2 participants during Early Access and General Access, provided the pool is not full and the staker has a remaining allotment above zero. However, staking additional LINK on an address that is already staking LINK in v0.2 will reset your ramp-up period for rewards, extending the time it takes for locked rewards to become fully claimable to 90 days. Locked Rewards will not be forfeited. For stakers who migrate during Priority Migration and stake more during the opening of Early Access, nine days of locked rewards accrued would become fully claimable in 90 days instead of 81 days. During General Access, consider staking any additional LINK from a new address to avoid resetting your ramp-up period, assuming pool space availability.
At any point in time, stakers can initiate a withdrawal of their staked LINK from v0.2, which begins a 28-day cooldown period. Once the cooldown period is complete, a seven-day claim window begins where staked LINK can be withdrawn. If the staked LINK is not withdrawn during the claim window, the LINK automatically re-enters v0.2. Therefore, if a staker changes their mind after initiating a withdrawal of their staked LINK, they do not have to take any action.
Staked LINK continues to accrue rewards during both the cooldown and claim window periods, up until any staked LINK is withdrawn. Note that withdrawing staked LINK via the unbonding mechanism may incur penalties on accrued rewards, depending on how long a staker has participated in v0.2.
The unbonding mechanism plays a key role in the security assurances provided with Chainlink Staking, namely by supporting the stability of the staking pool over extended periods of time and ensuring that there will be a sufficient amount of staked LINK available in the system to be slashed if a valid alert is raised (i.e., preventing withdraws before slashing can occur).
Are there penalties for withdrawing my staked LINK in v0.2?
Are there penalties for withdrawing my staked LINK in v0.2?
Withdrawing staked LINK via the unbonding mechanism may incur penalties on accrued rewards, depending on how long a staker has participated in v0.2.
Attributed Rewards are earned by stakers during their participation in staking, which are composed of Claimable Rewards and Locked Rewards. Claimable Rewards can be withdrawn by stakers at any time without penalty. Locked Rewards turn into Claimable Rewards over a period of time known as the ramp-up period. The ramp-up period is a 90-day period, tracked individually for each staker, that starts at 0% when a staker first stakes and linearly increases to 100% of the possible reward rate. The percentage of claimable Attributed Rewards is proportional to the amount of time spent in the ramp-up period.
For example, if a staker has progressed through 50% of their ramp-up period, then 50% of their Attributed Rewards become available as Claimable Rewards. After a staker has progressed through 100% of their ramp-up period, all previously earned Attributable Rewards are made available as Claimable Rewards, while any additional Attributable Rewards earned moving forward will automatically take the form of Claimable Rewards.
If a staker completes a withdrawal of any amount of their staked LINK, their ramp-up period will reset to 0% and any Locked Rewards earned will be forfeited back to the rewards pool and become available for all stakers in the same category (i.e., a Community Staker’s Forfeited Rewards can then be earned by all Community Stakers). After a withdrawal of staked LINK, a staker will need to go through the full ramp-up period again in order for Attributed Rewards to fully turn into Claimable Rewards.
Note that Claimable Rewards can be withdrawn at any point in time by a staker without resetting their ramp-up period progress. For Node Operator Stakers, the ramp-up period only applies to the base rewards on their staked LINK, but not for auto-delegation rewards from Community Stakers.
Are the penalties for withdrawing rewards from v0.2?
Are the penalties for withdrawing rewards from v0.2?
No, Claimable Rewards can be withdrawn at any point in time by a staker without resetting their ramp-up period progress. For Node Operator Stakers, the ramp-up period only applies to the base rewards on their staked LINK, but not for auto-delegation rewards from Community Stakers.
Token holders will be able to stake their LINK using the staking.chain.link webpage. Read this blog or watch this video for a step-by-step tutorial on how to stake your LINK in v0.2.
In order to stake LINK, you’ll need to have LINK tokens on Ethereum in a self-custodial wallet, where you can connect to Chainlink Staking v0.2’s frontend interface using a Web3 wallet such as MetaMask. Your wallet will also need to contain ETH to pay for Ethereum network transaction fees.
If I hold LINK tokens in a hardware wallet, how can I stake?
If I hold LINK tokens in a hardware wallet, how can I stake?
Many Web3 wallets, such as MetaMask, allow you to connect to hardware wallets as an additional layer of security. Refer to the official support documentation of your Web3 wallet and hardware wallet providers for best practices around using wallets in tandem.
If you have any additional questions, please follow up with your hardware wallet manufacturer.
Which Web3 wallets are supported for staking LINK?
Which Web3 wallets are supported for staking LINK?
Chainlink Staking currently supports widely-used Web3 wallets including MetaMask, Coinbase Wallet, and WalletConnect-enabled wallets. Smart contract wallets are also supported. Refer to the official support documentation of the above Web3 wallet providers for more information on connecting to Web3-enabled websites.
Why doesn’t MetaMask work on Brave Browser?
Why doesn’t MetaMask work on Brave Browser?
The Brave Wallet in the Brave web browser may conflict with the MetaMask browser extension, if installed. In order to resolve this issue when using MetaMask on Brave, the Brave Wallet must be disabled or a different web browser must be used.
Is Chainlink Staking Proof of Stake?
Is Chainlink Staking Proof of Stake?
No, Proof of Stake is a consensus mechanism used by some blockchain networks to validate blocks of transactions. Staking within decentralized oracle networks aims to achieve a fundamentally different goal from staking within blockchains—that is, the creation of reliable and tamper-resistant oracle reports that accurately reflect the state of the external world.
Staking is a core initiative of Chainlink Economics 2.0 that brings a new layer of cryptoeconomic security to the Chainlink Network. Staking enables ecosystem participants, such as node operators and community members, to back the performance of oracle services with staked LINK and earn rewards for helping secure the network.
In v0.2, Community Stakers can raise alerts regarding the performance of oracle services secured by Staking. v0.2 will launch with support for the ETH/USD Data Feed on Ethereum, where valid alerts can be raised by Community Stakers if there’s been more than three hours of downtime, with 20 minutes priority for alerting by Node Operator Stakers. Future iterative upgrades to Staking can include the expansion of Chainlink Staking to secure additional oracle services (e.g., CCIP) by adding new alerting conditions modules.
Staking in v0.2 will require an onchain transaction on Ethereum mainnet. Users should be aware of the dynamics around blockchain network resource availability.

Can my staked LINK be slashed?
Can my staked LINK be slashed?
The v0.2 upgrade to Chainlink Staking offers increased cryptoeconomic security by supporting the ability to slash a portion of staked LINK by Node Operator Stakers who help power oracle services secured by Staking. When a valid alert is raised and a slashing condition is met, these Node Operator Stakers will see a portion of their staked LINK slashed as a penalty for failing to meet performance requirements. At launch, Node Operator Stakers serving the ETH/USD Data Feed on Ethereum will be slashed 700 LINK each if a valid alerting condition is met. For raising a valid alert, the alerter will be rewarded 7,000 LINK.
Over time, the conditions around alerting and slashing amounts are expected to evolve, particularly as Chainlink Staking expands to support more oracle services. In v0.2, Community Stakers will not be at risk of slashing, with such a change requiring a migration to a new Staking version. Additionally, Node Operator Stakers only serving oracle services not secured by staking will not be at risk of slashing.
The Staking v0.2 smart contracts have undergone multiple audits from a number of independent and industry-leading auditors. The codebase also underwent a time-limited competitive audit program on the Code4rena platform.
Is Staking v0.2 non-custodial?
Is Staking v0.2 non-custodial?
Yes, the Chainlink Staking smart contracts in v0.2 will remain non-custodial, meaning stakers always have complete control over their staked LINK, which cannot be withdrawn by any other entity. Any future migration from v0.2 to a new Staking version will continue to involve a manual migration from stakers, similar to v0.1.
Can the v0.2 contracts be upgraded?
Can the v0.2 contracts be upgraded?
For any iterative upgrade to the modular Chainlink Staking v0.2 codebase that materially impacts stakers, such as the modification of slashing conditions, upgrades will be announced proactively such that stakers can choose to initiate and complete a withdrawal of their staked LINK before the upgrade is completed onchain.
As an additional security measure, all onchain security-critical configuration changes and upgrades to Chainlink Staking v0.2 must pass through a timelock smart contract featuring a time delay of up to a few weeks, with critical configuration changes taking the longest (longer than the unbonding period). This timelock mechanism allows the community to review and choose to opt out of such changes before they are implemented onchain. Only emergency functions that are designed to protect stakers and certain ministerial functions, such as adding rewards, can be called without a time delay. However no configuration changes or upgrades can be deployed without going through the timelock.

When can I withdraw from v0.1?
When can I withdraw from v0.1?
Upon the launch of v0.2 Priority Migration on November 28, 2023 at 12PM ET, v0.1 stakers will have the ability to migrate all or a portion of their v0.1 staked LINK and rewards to v0.2 or withdraw to their own wallets. Note that stakers who withdraw their staked LINK from v0.1 do not need to go through a cooldown period, as the unbonding mechanism is a new feature introduced in v0.2.
Given that the v0.2 pool is larger than the v0.1 pool, and accounting for accrued rewards, v0.1 stakers have guaranteed access to v0.2 if they participate in the Priority Migration phase. Once the Priority Migration period ends, v0.1 stakers can still migrate or withdraw during Early Access and General Access; however, entry to v0.2 will not be guaranteed due to the capped pool size.
How do I migrate my v0.1 staked LINK from v0.2?
How do I migrate my v0.1 staked LINK from v0.2?
On November 28, 2023 at 12PM ET, v0.1 stakers have the exclusive opportunity to migrate their v0.1 stake and accrued LINK rewards to v0.2 or withdraw. The Priority Migration period will last for nine days, where v0.1 stakers can choose to migrate all or a portion of their v0.1 stake and rewards. Once the Priority Migration period ends, v0.1 stakers can still migrate or withdraw during Early Access and General Access; however, entry to v0.2 will not be guaranteed due to the capped pool size. Migration will take place on staking.chain.link. Read this blog or watch this video for a step-by-step tutorial on how to migrate your v0.1 staked LINK to v0.2.
No, the migration process involves a single transaction where staked LINK and rewards are transferred directly from the v0.1 staking pool contract to the v0.2 staking pool contract. Note that migration is only available if there is sufficient space in the pool and is only guaranteed during the nine-day Priority Migration period.
Can I migrate or stake from a different address during Priority Migration or Early Access?
Can I migrate or stake from a different address during Priority Migration or Early Access?
Upon the launch of v0.2, existing v0.1 stakers have the option to migrate to v0.2 using the same address they originally staked with, with guaranteed access during Priority Migration, or withdraw their staked LINK and rewards to their wallet. Ownership of staked LINK, in either v0.1 or v0.2, cannot be transferred to a new address, but instead must be unstaked to transfer. Early Access eligibility cannot be transferred to a different address.
If I withdraw my v0.1 staked LINK during Priority Migration, can I still migrate to v0.2?
If I withdraw my v0.1 staked LINK during Priority Migration, can I still migrate to v0.2?
Only active v0.1 stakers are able to migrate to v0.2. v0.1 stakers who withdraw during Priority Migration will have the opportunity to stake once Early Access opens, however access will not be guaranteed given the limited pool size. Only v0.1 stakers who choose to migrate to v0.2 during Priority Migration will have guaranteed access to v0.2.
What happens to my v0.1 staked LINK if I do not migrate to v0.2?
What happens to my v0.1 staked LINK if I do not migrate to v0.2?
Staking v0.1 will become inactive upon the launch of v0.2 and will no longer emit rewards. Stakers in v0.1 can choose to migrate or withdraw their v0.1 staked LINK and rewards at any point in time after the launch of v0.2, however, access to v0.2 won’t be guaranteed after the Priority Migration Period ends.
Note that the smart contracts for Chainlink Staking v0.1 and v0.2 are non-custodial by design, meaning no entity other than the staker themselves can withdraw or migrate their LINK. v0.1 stakers will need to provide explicit approval to migrate or withdraw their staked v0.1 LINK and rewards by signing an onchain transaction.
