LINK Token Contracts for the Chainlink Network

LINK Token Contracts

The LINK token is an EIP20 token with additional ERC677 functionality.

The total supply of the token is 1,000,000,000, and each token is divisible up to 18 decimal places.

To prevent accidental burns, the token does not allow transfers to the contract itself and to 0x0.

Security audit for v0.4 version of the contracts is available here.

Installation

The project contains v0.4 contracts that were used for LINK Ethereum Mainnet deployment in 2017. For deployments moving forward, we use the updated v0.6 contracts which use a more recent version of solc and the OpenZeppelin token standards. These updates include a minor ABI change around approval/allowance naming.

yarn install
