The problem Private On Chain Line of Credit using ZKP solves

Allow financial institutions to start providing their services in public blockchain networks.
At present they are wasting resources in private/permissioned blockchain solutions.
Once privacy is added to public blockchains through ZKPs, enterprises can start providing their services directly on-chain while mantain some information private.

This project is a first step with a simple financial product towards this direction.

It is a Line of Credit where:

• the terms and conditions remain private between the client and the financial institution.
• the client can submit a proof on-chain and withdraw (24/7) any stablecoin directly on-chain and use it instantly
• without human intervention
