LINK Token Contracts

Suggest Edits

LINK tokens are used to pay node operators for retrieving data for smart contracts and also for deposits placed by node operators as required by contract creators.

The LINK token is an ERC677 token that inherits functionality from the ERC20 token standard and allows token transfers to contain a data payload. Read more about the ERC677 transferAndCall token standard.

Other EVM Compatible Chains

LINK is native to Ethereum, so to use LINK on other chains, it must be bridged. This guide explains how to bridge and swap tokens to other chains.

Binance Smart Chain

Mainnet

Important

The LINK provided by the Binance Bridge is not ERC-677 compatible, so cannot be used with Chainlink oracles. However, it can be converted to the official LINK token on BSC using Chainlink's PegSwap service.

Polygon (Matic)

Important

The LINK provided by the Polygon (Matic) Bridge is not ERC-677 compatible, so cannot be used with Chainlink oracles. However, it can be converted to the official LINK token on Polygon (Matic) using Chainlink's PegSwap service
