🐐 Description

This repository acts as a Proof of Concept for the application that is the final product of this project. The Goals of the whole project, which are explained down below, are ambitious. To make sure our goals are within reach of the team and to make sure the existing ecosystem and technologies are matured enough, this Proof of Concept was built to implement each use-case in a minimal way.

🚀 Unique Features

Free transactions

Send, receive or do whatever you want with your stablecoins, for free. (Additional tokens included)

Fully banking compatible

Don’t be cut off. Use SEPA and Wiretransfer, without owning Fiat. Debitcards are in the planning.

No Know-How required

You don’t know anything about blockchains? That's not necessary. We abstract all the complicated stuff away.

✅ Goals of this Prototype

1. Fully non-custodial wallet
2. High Security by relying on Multi Party Computation (Based on Unbounds C++ MPC Library)
3. Use of known and established handling such as in mobile banking apps
4. No requirements of new know-how by users
5. Complete gasless (free) transfers of stablecoins (including various other tokens)
6. Full interoperability between the blockchain and traditional banking part - but without having to own FIAT (utilizing Circle)
7. Absolute transparency through building in public (open source github repository)

🔝

⚒️ Goals for the Future

1. Audit Security
2. Streamline USDC/Polygon features via new UI
