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

Parameters

address

string

REQUIRED

The address of the smart contract from which the bytecode will be obtained

blockNumber

string

REQUIRED

The block number as a string in hexadecimal format or tags. The supported tag values include earliest for the earliest/genesis block, latest for the latest mined block, pending for the pending state/transactions, safe for the most recent secure block, and finalized for the most recent secure block accepted by more than 2/3 of validators. safe and finalized are only supported on Ethereum, Gnosis, Arbitrum, Arbitrum Nova, and Avalanche C-chain. On Avalanche C-Chain, pending resolves to the last executed block when api-resolve-pending-to-last-executed is true (the default).

Returns

result

string

The bytecode from a given address returned as a string
