Viem Version

2.46.1

Current Behavior

// 1. Import modules.
import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';

// 2. Set up your client with a desired chain & transport.
const client = createPublicClient({
  chain: mainnet,
  transport: http('http://localhost:8545'),
});

const start = async () => {
  const blockNumber = await client.getBlockNumber();

  const block = await client.getBlock({ blockNumber });

  const balance = await client.getBalance({
    address: '0x8D97689C9818892B700e27F316cc3E41e17fBeb9',
    blockTag: { blockHash: block.hash } // <<- type error
  });

  console.log(blockNumber, block.hash, balance);
};

start().catch((e) => console.error(e));

Expected Behavior

// 1. Import modules.
import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';

// 2. Set up your client with a desired chain & transport.
const client = createPublicClient({
  chain: mainnet,

  const block = await client.getBlock({ blockNumber });

  const balance = await client.getBalance({
    address: '0x8D97689C9818892B700e27F316cc3E41e17fBeb9',
    blockTag: { blockHash: block.hash } // this should be possible with EIP-1898
  });

  console.log(blockNumber, block.hash, balance);
};

start().catch((e) => console.error(e));
