# eth\_maxPriorityFeePerGas - Celo

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

This method returns the current max priority fee per gas (tip) for EIP-1559 transactions on the Celo network. This is used to incentivize faster transaction inclusion.
