Defined in: src/chains/index.ts:107

Looks up a supported chain by its numeric chain ID.

The returned chain’s id is narrowed to SupportedChainId.

Parameters

chainId

number

The numeric chain ID to look up.

Returns

The matching KawaseChain.

Throws

If chainId is not supported.

Example

import { getChain } from "kawasekit";

const chain = getChain(80002); // Polygon Amoy
console.log(chain.name);
