Describe the problem:
Arbitrum transactions are overestimating the amount of ETH used as gas for transactions. Looking at the raw data, it looks like Koinly is taking the “gas price bid” from arbiscan, rather than the “gas price used”. This leads to an overstimation of losses and possibly issues with finding cost basis in later transactions
Which exchange/wallet is this regarding?
How did you import data into this wallet?
Arbitrum Wallet integration
What have you tried to fix this so far?
I tried correcting the Fee field, but Koinly does not allow you to change the ETH fee, only the USD value
