Layer 3 bidirectional payment channel solution on top of Layer 2


We are building a service that allows the creation of unidirectional payment channels on top of existing Layer 2 solutions. Furthermore, it focuses on really intuitive UX, meaning it takes care of sending the off-chain signatures in a simple yet secure way to the other party. It is a way for users to make instant and secure transactions by sending all of their transactions off-chain (expect the opening and the closing of the channel) showcase

How it's made

The project built its own custom payment channel solution written in solidity and deployed to the Matic Mumbai Testnet and is fully integrated with Polygon We used React for the front-end and using special libraries like web3-react and ethers there to explore the available solutions AWS was used for the backend to improve the UX of the app (in an optional way so our project is still completely decentralized)
