Gas fee consumption on Base VS mainnet

Hi all,

We launched a project on mainnet recently and experienced an issue around excess ETH above max wallet in transactions being consumed as gas.

Examples:

Contributing factors: - very high gwei pricing at time of launch - max wallet 0.25% on launch - low initial liquidity - high gas usage by transactions (due to contract complexity)

Results were that those that attempted to send more ETH than max wallet was worth resulted in the remaining ETH in the transactions being consumed as gas.

We are going to migrate to Base in order to significantly lower all transaction costs. I am trying to determine if this issue will follow us to Base on relaunch.

Things that will be different on relaunch: - higher initial liquidity - max wallet now 2% - no whitelist launch so less people botting launch with unlimited gas limits

In my testing on Base Sepolia, TX's that exceed max wallet all fail.

Just hoping to get some insight into these transactions as the result was obviously not ideal for the project.

My impression is that this issue will not follow us to Base, simply due to gwei pricing. Even if the transaction consumes the gas limit, this will still only be a couple of dollars.

Any opinions or insight would be awesome. Cheers.
