// (add custom chain in ./ponder.address.ts)
// mainnet (default), ethereum3, polygon
const chain =
	(process.env.PONDER_PROFILE as string) == 'polygon'
		? polygon
		: (process.env.PONDER_PROFILE as string) == 'ethereum3'
		? ethereum3
		: mainnet;

const CONFIG = {
	[mainnet.id]: {
		rpc: process.env.RPC_URL_MAINNET ?? mainnet.rpcUrls.default.http[0],
		startBlockA: 18451518,
		startBlockB: 18451536,
