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

Parameters

transaction

object

The transaction call object:

from

string

The address from which the transaction is sent

to

string

REQUIRED

The address to which the transaction is addressed

gas

integer

The integer of gas provided for the transaction execution

gasPrice

integer

The integer of gasPrice used for each paid gas encoded as hexadecimal

value

integer

The integer of value sent with this transaction encoded as hexadecimal

data

string

The hash of the method signature and encoded parameters. For more information, see the Contract ABI description in the Solidity documentation.

blockNumber

string

The block number in hexadecimal format or the string latest, earliest, pending, safe or finalized. On Avalanche C-Chain, pending resolves to the last executed block when api-resolve-pending-to-last-executed is true (the default).

Returns

quantity

string

The estimated amount of gas used
