ChainLink Token (Chainlink) (LINK) is the native token of the Chainlink oracle network, an infrastructure layer that delivers external data feeds and cross-chain messaging to smart contracts.
LINK is deployed on Ethereum (native/canonical deployment) and also exists as officially bridged representations on more than 60 other chains, including BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, and Solana. The network is categorized as an Oracle protocol. The token contract was deployed on 2017-09-16, and the underlying Chainlink network went live in June 2017.
Chainlink's core value lies in operating a decentralized oracle network that generates on-chain economic activity through fees for data and cross-chain services.
Over the trailing 30 days ending 2026-08-30, the network generated approximately $4.46 million in protocol fees and $4.48 million in revenue across roughly 3.5 million on-chain contract transactions. Its Cross-Chain Interoperability Protocol (CCIP) is being adopted for institutional use cases, including powering Coinbase's tokenized U.S. equities and Wyoming's state-issued stable token, extending LINK's utility beyond price-feed delivery.
LINK functions as a utility token that pays node operators for delivering data feeds and cross-chain messages, rather than as a governance token with on-chain voting rights.
Holders can stake LINK through the Chainlink Staking program (v0.2, launched Q4 2023) as Community or Node Operator stakers, earning rewards for supporting network security; node operators face slashing of staked LINK for service failures.
LINK has a fixed maximum supply of 1,000,000,000 tokens, with no further minting possible.
Net emission is disinflationary: the supply cap is fixed at genesis, and circulating supply grows only as previously allocated (non-public-sale) tokens unlock over time, gradually approaching the 1 billion cap rather than expanding it.
LINK launched via a 2017 initial coin offering (ICO), raising $32 million from approximately 2,649 contributors at about $0.0914 per token. The ICO ran from September 19 to October 19, 2017.
The token's on-chain contract was deployed on 2017-09-16, shortly before the ICO closed, while the broader Chainlink network had already launched in June 2017 — meaning the network's founding predates both the token deployment and the ICO.
LINK is deployed as an ERC-20 token on Ethereum, which secures the network through proof-of-stake consensus.
Chainlink also maintains official bridged/wrapped representations of LINK on more than 60 additional chains, including BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, and Solana, functioning as multi-chain mirrors of the same Ethereum-native asset rather than separate tokens.
The Chainlink oracle network itself operates through independent, staked node operators that report data off-chain and settle on Ethereum, adding a network-level security layer distinct from Ethereum's own consensus.
Chainlink was co-founded in 2017 by Sergey Nazarov, who serves as CEO of Chainlink Labs, and Steve Ellis, who serves as CTO of Chainlink Labs.
Nazarov and Ellis co-authored the original Chainlink whitepaper together with Cornell University professor Ari Juels. The team is publicly identified, not anonymous or pseudonymous.
Chainlink Labs, formerly known as SmartContract.com, is the primary corporate developer that builds and maintains the core Chainlink software.
A separate non-profit, the Chainlink Foundation, oversees ecosystem grants and aspects of decentralization policy independently of Chainlink Labs' commercial development work.
Chainlink does not use fully on-chain, token-holder voting governance; instead, strategic and development direction is set by Chainlink Labs, with decentralization introduced through staking.
Under Staking v0.2 (launched Q4 2023 with an initial pool of 45,000,000 LINK), Community and Node Operator stakers gain a reputation- and stake-weighted voice in network operations, and node operators can be slashed for security failures.
The Chainlink Foundation separately manages ecosystem grants and decentralization policy, with influence gradually shifting from the founding team toward stakers and node operators.
Recent Chainlink development has centered on expanding adoption of CCIP (Cross-Chain Interoperability Protocol) across institutional and public-sector use cases.
Chainlink's core protocol has been audited by multiple third-party firms, including Quantstamp, SigmaPrime, Callisto, and OpenZeppelin, alongside independent researcher Nick Johnson.
CCIP has undergone dedicated reviews: Code4rena competitive audits in May 2023 and November 2024 (the latter with a $235,000 USDC prize pool), and a Cyfrin audit of CCIP v1.5. Chainlink has stated that CCIP holds ISO 27001 and SOC 2 Type 2 certifications.
No major hack of the core oracle network was identified. Holder concentration is comparatively elevated: the top 10 addresses hold roughly 32% of circulating supply as of 2026-08-31.
