Usage
import { Multicall } from 'klaytn-multicall';
const caver = new Caver(...);
const multicall = new Multicall({ provider });
const staking = new caver.klay.Contract(...);
const calls = [
staking.methods.balanceOf(
'0x7777777141f111cf9f0308a63dbd9d0cad3010c4',
),
staking.methods.rewardsOf(
'0x7777777141f111cf9f0308a63dbd9d0cad3010c4',
),
];
await multicall.aggregate(calls)
.then((console.log));

// Queries KLAY balance of address

Customization
You can inject contract address of your custom implementation, too:
new Multicall({
provider,
multicallV2Address: '0xd11dfc2ab34abd3e1abfba80b99aefbd6255c4b8',
});
multicallV2Address defaults to 0xd11dfc2ab34abd3e1abfba80b99aefbd6255c4b8(Multicall2 deployed in Cypress).
