{<h3>Predict the next base fee</h3>}
OP Mainnet adjusts the base fee based on the amount of gas used in the previous block.
If the previous block used more than 5m gas (of the 30m gas limit), then the base fee will increase by up to 10%.
If the previous block used less than 5m gas, then the base fee will decrease by up to 10%.

{<h3>Select a base fee per gas</h3>}

Using the current base fee per gas and the amount of gas used in the previous block, you can predict the next base fee per gas.
If you are highly sensitive to the base fee, you may want to select a base fee per gas that is either 10% higher or 10% lower than the previous base fee.
However, you may run the risk that your transaction will not be included in a block quickly.
If you are less sensitive to the base fee, you may wish to simply use a large multiple of the previous base fee (e.g. 2x).

## Selecting the priority fee

You can also use the [`eth_feeHistory`](https://docs.alchemy.com/reference/eth-feehistory) JSON-RPC method to retrieve historical priority fee data.
You can then use this data to predict a reasonable priority fee for your transaction.

Alternatively, you can rely on Tenderly's [`tenderly_gasPrice`](https://docs.tenderly.co/node/rpc-reference/optimism-mainnet/tenderly_gasPrice?mtm_campaign=ext-docs&mtm_kwd=optimism) to get real-time gas predictions with 3 levels of likelihood for transaction inclusion.
