Is chain link an erc20 token

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 smallest denomination of LINK is called a Juel, and 1,000,000,000,000,000,000 (1e18) Juels are equal to 1 LINK. This is similar to Wei, which is the smallest denomination of ETH.

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.

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.

BNB Chain

Mainnet

Important

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

Polygon (Matic)

Mainnet

MATIC is used to pay for transactions on Polygon mainnet. You can use the Polygon Bridge to transfer tokens to Polygon mainnet and then use Polygon Gas Swap to swap supported tokens to MATIC.

ERC-677 LINK on Polygon

The LINK provided by the Polygon (Matic) Bridge is not ERC-677 compatible, you cannot use it with Chainlink services. However, you can convert LINK to the official ERC-677 compatible LINK token by using the Chainlink PegSwap service.
