# eth_estimateGas

# `eth_estimateGas`

Returns an estimate of gas needed to execute a transaction. The transaction is not sent.

note

For more accurate gas estimation on Linea, use [`linea_estimateGas`](/api/reference/linea-estimategas) instead. It returns the gas limit, base fee per gas, and priority fee per gas in a single call, accounting for Linea's L1 data-submission costs.

## Parameters

-   `transaction`: _[required]_ Transaction call object (same fields as [`eth_call`](/api/reference/eth-call)).
-   `blockParameter`: _[optional]_ Hexadecimal block number, or `latest`.

## Returns

Hexadecimal value of the estimated gas.
