To use the eth_getBalance method on the Avalanche C-Chain, ensure that the end of your URL includes ext/bc/C/rpc.

Parameters

address

string

REQUIRED

The address (20 bytes) to check for balance

blockNumber/tag

string

REQUIRED

The block number in hexadecimal format or the string latest, earliest, pending, safe or finalized (safe and finalized tags are only supported on Ethereum, Gnosis, Arbitrum, Arbitrum Nova and Avalanche C-chain), see the default block parameter description in the official Ethereum documentation. On Avalanche C-Chain, pending resolves to the last executed block by default. When api-resolve-pending-to-last-executed is false, this method rejects pending.

Returns

result

string

The value of the balance of the specified address in hexadecimal value, measured in wei
