eth_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be processed in Radius.

NOTE

The gas estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and system performance.

Parameters

• from: 20 bytes - Address the transaction is sent from.

• to: 20 bytes - Address the transaction is directed to.

• gas: Hexadecimal value of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.

• gasPrice: Hexadecimal value of the gasPrice used for each paid gas.

• maxPriorityFeePerGas: Maximum fee (in wei) the sender is willing to pay per gas above the base fee. See EIP-1559 transactions.

• maxFeePerGas: Maximum total fee (base fee + priority fee, in wei), the sender is willing to pay per gas. See EIP-1559 transactions.

• value: Hexadecimal of the value sent with this transaction.

• data: Hash of the method signature and encoded parameters. See Ethereum contract ABI specification.

• block parameter: A string representing a block number, block hash, or one of the string tags latest, earliest, pending, safe, or finalized. See the default block parameter.

Returns

A hexadecimal of the estimate of the gas for the given transaction.
