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 target of contract if any (i.e. a Proxy) 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)
