eth_gasPrice - Base

Example code for the eth_gasPrice JSON-RPC method. Complete guide on how to use eth_gasPrice JSON-RPC in GetBlock Web3 documentation.

The eth_gasPrice method returns the current gas price on the Base network in wei. This value represents the L2 execution fee component. Note that Base transactions also incur an L1 data fee for posting transaction data to Ethereum mainnet.

Parameters

None
