ETHover

Ethereum Account Address Hover Info and Actions

Marketplace

Hover over an ethereum address and:

• Open it in etherscan (or whatever you configure)
• Show address balance in hover (mainnet) (note: might be rate-limited, configure your API key in settings)
• Download the bytecode and disassemble it.
  • With hover info on instructions
  • Representation of data as ASCII and resolving 4bytes to funcsigs, Color code reflects the type of instruction: stack, memory, storage, arithm., logic, system, environment, …
• Download the bytecode and show it.
  • With hover info
  • Click to see instruction boundaries
  • Color coded bytes to reflect type of instruction)
• Show verified contract source (etherscan.io)
• Show reconstructed contract source from eveem.org
• Show reconstructed contract source from evm.js
• run vscode-decompiler to decompile it manually using panoramix (eveem.org) locally

Currently enabled for the following filetypes

• TypeScript
• JavaScript
• Markdown
• Solidity

Let me know if you want to enable this extension for more filetypes.

vscode-ethover's Issues

support for bsc/other eth-like chains?

works to some extent already by changing block explorer address, but would be nice to be able to work with multiple chains too

Failing to retrieve evm.js reconstructed source code

Selecting evm.js from the hover options results in no contract code being returned. Instead, it seems to hang and load indefinitely.

Windows 10.0.18363
VSCode 1.47.2

Support Retrieving Verified Contracts Unflattened

Currently when hovering on an address and clicking on "VerifiedContract" it retrieves the source code of the Smart Contract deployed at that address, but in case the Smart contract is composed of multiple files it outputs a flattened version of the Smart Contract.

it would be nice to either retrieve all the files in a folder or alternatively to give the user an option to choose between flattening or not

enable for python filetypes

Hi,

I wonder if you could enable this extension for python. It would be useful with https://github.com/eth-brownie/brownie, a python development and testing framework for smart contracts.

Cheers.

"enable for this file" command

while it's nice it's available for js, ts etc, it would also be useful when viewing log files and so on. one-time command seems like a better tradeoff than trying to guess the file formats

Support proxy contracts / ability to execute view functions on verified contracts

I was trying to view the source of a contract, but his contract uses the EIP-1967 proxy pattern, so I couldn't view the underlying logic.

There are two potential features I can think of to enable viewing of the underlying logic (which is why this issue covers two feature requests):

1. Natively support proxy contracts, with a separate option on hover to view the source underlying implementation. Not sure how big the scope is here since there's at least EIP-1967 and EIP-1167, and possibly others
2. Allow view functions to be called and if the result is an address, allow it to be actionable

Enable the extension for Vyper files

It would be good for the extension to be active for Vyper file type (.vy) as those often contain Ethereum addresses.

Please add the new opcodes
