Drill

If you are using a blockchain without mempool access such as Arbitrum, drill tool can allow you to still be the first to perform an action.

Drill works in a very simple way, it sends out transactions in quick succession until it is turned off. This "spam" tactic can allow you to achieve same-block ordering even without mempool access.

You can either set an interval at which transactions will be sent, or check the wait until previous confirmed box, which will send the next transaction only after the last one has confirmed.

it is important that you set your gas correctly when using this tool, as fees can add up quickly if improperly set. It is recommended that you set the maxPriorityFeePerGas to a very low value rather than {auto}, to be sure you are not wasting any wei if the gas price on chain is near zero, as is sometimes the case on Arbitrum.
