Ethgate
Ethgate is a library for making batched calls to Ethereum compatible calls.
This library is very experimental. Even documented features might not work.
Usage
import { Contract as EthersContract } from '@ethersproject/contracts';
import { InfuraProvider as EthersInfuraProvider } from '@ethersproject/providers';
import { EthgateChain } from 'ethgate';
const ethersMainnetProvider = new EthersInfuraProvider('homestead');
const mainnet = new EthgateChain(ethersMainnetProvider, 1);
const ensRegistryContract = new EthersContract(
'0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e',
ensRegistryContractInterface,
);
const names = ['resolver.eth', 'cardpunks.eth', 'alicanc.eth'];
const results = await Promise.all(
names.map(async (name) => {
const namehash = hashEnsName(name);
const [recordExists, owner, resolver] = await Promise.all([
mainnet.call(ensRegistryContract, 'recordExists(bytes32)', [namehash]),
mainnet.call(ensRegistryContract, 'owner(bytes32)', [namehash]),
mainnet.call(ensRegistryContract, 'resolver(bytes32)', [namehash]),
]);
return { recordExists, owner, resolver };
}),
);
// You now have the results and only one RPC call has been made!
