Problem
In, #4559 we noticed that truffle was displaying incorrect transaction fees when using Arbitrum. This has to do with complexity that exists for their L2 that makes
transaction.gasPriceunreliable compared toreceipt.effectiveGasPrice. However, this isn't a problem that we need Arbitrum-specific code to support becausegasPricehas been officially deprecated in favor ofeffectiveGasPricepost-EIP-1559 anyway.Solution
When reporting transactions fees, set the gas price to
receipt.effectiveGasFeeif it exists, otherwisetransaction.gasPriceTo do
Check that this works on different versions of ganache, EIP-1559 & legacy transactions, Arbitrum & Ethereum.
