Dig into Ethereum transactions and reveal their secrets; kinda like having Etherscan in your code.

) and adds that ABI as wellNote: due to storage limitations of popular Ethereum providers, you won't get revert reasons for most transactions more than 128 blocks in the past unless you use an Infura archive node (see https://infura.io/docs/ethereum/add-ons/archiveData)
