Institutional Wallet
A wallet for enterprises: fine-grained, adjustable permissions for employees
Demo
About
An institutional wallet that lets organizations control what employees do with organizational funds, while keeping the organizational wallet secure. Institutional funds are kept secure by Privy. Substreams are used to monitor for unauthorized transactions on-chain and alert if that happens.
How it's made
Under the hood, this is Privy + Substreams. Admins can add employees to policy groups, which are threshold-one key quorums in privy. The actual secret key is kept secure by privy. Sign-in is currently done with Google + email OTP. Nonetheless, substreams are used to monitor for unauthorized/unexpected transactions, which would indicate that the private key was still somehow stolen. In that case, admins are alerted. To monitor across native tokens, ERC-721, and ERC-1155, I created and published a new Substream: https://substreams.dev/packages/institutional-wallet-custody-evm/v0.1.0. The Substream was deployed using one prompt (and a bunch of detailed project description files + the SKILLs).
