Show reverse-engineered ABI

[ulyanas]

WhatsABI tool can guess a contract's ABI and detect proxies from an Ethereum bytecode, even if it's unverified.

Using this tool we can show guessed ABIs for unverified contacts.

UI:

• Show reverse-engineered ABI methods
• Show unknown functions in the end (probably we need UI mockup here)
• Show message:

MyAccount turned on:

The ABI used here was reverse-engineered using whatsabi. It may contain errors.
You can upload your own ABI instead. It will remain private.

Upload link: <chain url>/account/custom-abi

MyAccount turned off:

The ABI used here was reverse-engineered using whatsabi. It may contain errors.
