Eth-Reveal
Dive into Ethereum transactions from the CLI or via a module.
Use it live in Codepen: https://codepen.io/justinjmoses/full/vwexLj
Features
- Decodes method calls, function parameters and logs (with formatted dates and numbers) using ABI from Etherscan (if any)
- Looks for
targetof contract if any (i.e. aProxy) and adds that ABI as well - Shows errors and revert reasons
Note: 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)
