eth_call on BNB Chain

Executes a message call against the EVM without creating a transaction — the backbone of every contract read (balanceOf, totalSupply, etc.). Returns the call's return data.

Runs against a chosen block's state with no gas paid; override from/value/block to simulate a sender or a past state. It surfaces the contract's revert reason, which is how you catch errors like 'insufficient allowance' before sending a real tx.

Contract calls on BNB Chain

eth_call behaves as on any geth-lineage chain. With ~0.75 s blocks, "latest" changes faster than your request round-trip — pin a block number when making multiple related reads.

Parameters

[callObject, blockNumber|tag]

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider(
