Also 421611 => "arbitrum_testnet"

BTW, I'm using uniswap-python on arbitrum, and I had to monkey patch_get_tx_params and remove the "gas" parameter, otherwise I was receiving "insufficient funds for gas". Perhaps it's something specific to my setup, but I thought that it might be useful for others if they also face such problem.

I've checked some uni swaps on arbitrum and it turns out txn requires gas spendings ~1m but_get_tx_param has hardcoded 250k limit. So I'm quite sure it isn't about your setup.

Yes, I can testify: 1,078,834
I wasn't sure that it's not something specific to my case. I'm curious why it's different from L1 gas usage.

Perhaps the gas parameter could be removed entirely from_get_tx_params? Perhaps we should useestimate_gas instead?

Could it be because each LP position is smaller, and this impacts gas efficiency? (just guessing) Edit: Nevermind, answers herehttps://developer.offchainlabs.com/docs/arbgas

Merging this for now, we'll deal with any issues in future PRs.

Uniswap3 suggest doing 1.2 * estimateGas. I can make a PR if you want.

@romanbsd That would be appreciated :)
