View ChartChainlink is a decentralized oracle network and blockchain middleware that communicates off-chain data to blockchains. Its oracles securely enable computations both on and off the blockchain, supporting hybrid smart contracts and cross-chain interoperability. Chainlink's oracle network allows blockchains to connect to off-chain data and computation resources. Through a decentralized oracle network (DON), Chainlink brings off-chain data and computation resources to smart contracts, and through CCIP it enables messaging across blockchains and with traditional financial systems.
Chainlink introduced the Cross-Chain Interoperability Protocol (CCIP) in 2023 to enable communication between applications across blockchains and traditional financial systems. CCIP 2.0 launched on October 7, 2026, adding institutional Cross-Chain Verifiers and compliance controls. CCIP has secured over $84 billion in total cross-chain token value, with $15 billion migrating in four months.
Chainlink has also integrated several technical components. In 2018 it integrated Town Crier, a trusted execution environment-based blockchain oracle connecting the Ethereum blockchain with web sources that use HTTPS. In 2020 it integrated DECO, a Cornell project co-created by Ari Juels that uses zero-knowledge proofs to allow users to prove information is true to a blockchain oracle without revealing sensitive information, and launched its Proof-of-Reserve (PoR) system to help cryptocurrency projects and tokenized-asset issuers verify asset backing.
According to CoinMarketCap, institutions and infrastructures adopting Chainlink include Swift, DTCC, Euroclear, J.P. Morgan, Mastercard, the Central Bank of Brazil, UBS, SBI, Fidelity International, and ANZ.
LINK is an ERC-20 token on Ethereum, with the contract address 0x5149…f986ca (shown in truncated form on CoinMarketCap), verifiable on etherscan.io. The LINK token runs on Ethereum, which uses a proof-of-stake operating protocol. Additionally, Chainlink is an open-source project, enabling anyone to view and contribute to the project's code.
Chainlink was created in 2017 by Sergey Nazarov and Steve Ellis, who co-authored a white paper with Cornell University professor Ari Juels; the network officially launched in 2019 to address an issue known as 'the blockchain oracle problem'. Oracles are network entities that handle traffic between two non-compatible systems. The blockchain oracle problem affects all blockchains because they are essentially closed systems that cannot push or pull data to or from outside systems.
Blockchain protocols cannot permit this ability as it would compromise the security that blockchains are renowned for. Additionally, oracles enable data from external sources to trigger smart contracts, which is not something that blockchains are designed to do.
CCIP has secured over $84 billion in total cross-chain token value, with $15 billion migrating in four months. Transaction Value Enabled (TVE) stands at $36,415,397,882,658 as of October 6, 2026.
It has a maximum supply of 1 billion LINK, with a current circulating supply of approximately 748.09 million LINK (about 74.81% of the total).
In some ways, the Chainlink network complements the Ethereum network and other blockchains. It can facilitate secure communication between Ethereum projects and various off-chain data sources. LINK is an ERC-20 token on Ethereum (ERC677 retains all the functionality of an ERC-20 token) and can be stored in any ERC-20 wallet.
Ethereum tokens can be used for purchases, to facilitate smart contracts, and to pay validators for operating the Ethereum network. In contrast, LINK is the utility and governance token of Chainlink, used to pay node operators, staked by community participants to support the network's cryptoeconomic security, and supported by a fee model in which offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve. LINK is a fixed-supply token that pays for and secures an oracle network, not a gas token for a chain, with total supply capped at 1 billion LINK.
LINK can be purchased on several major exchanges and can also be stored in any ERC-20 wallet. Community participants can stake LINK to support the network's cryptoeconomic security. The Ethereum contract address is 0x5149…f986ca, which readers can verify on etherscan.io.
