Metamask Snap used to get human-readable transaction description from Sourcify
npm install sourcify-snap!Screen-Recording-2022-12-20-at-7
MetaMask Snaps is a system that allows anyone to safely expand the capabilities of MetaMask. A _snap_ is a program that we run in an isolated environment that can customize the wallet experience.
This snap uses Sourcify to get information about the contract with which the transaction is about to happen and provides a human-readable description of what is about to happen in the transaction.
> Warning
> The human-readable description of the funciton is generated from the NatSpec comment on the function. So don't trust it blindly!
> Note
> The site has a example tx inside packages/site/pages/index.tsx
