Overview

Noir Pay v0

Built on Light Protocol

Noir Pay will be directly built ontop of the Light Protocol SDK and provide users with a beautifully simple private payments solution via our frontend. Have you ever thought about privately paying via Solana Pay. This repo represents a fork of the light protocol program which is built as a single unfractured shielded pool for SPL tokens. This purpose of this fork is to work on local optimisations and bug testing as contribution towards the Light Protocol SDK.

DISCLAIMER: THIS SOFTWARE IS NOT AUDITED. Do not use in production!

Testing the Program

First clone the repo locally.

git clone https://github.com/Lightprotocol/light-protocol-program.git

Then run these commands in order, it is important that you run the tests one after the other as this is how the functional flow of zk-PROOFs work. You cannot withdraw funds that no proof was ever generated for.

cd ./program && cargo test-bpf deposit_should_succeed
./program && cargo test-bpf withdrawal_should_succeed

Please note this will only currently work on Linux/Mac OSX environment's due to the need for the Solana Rust BPF Toolchain. - I have tested it from within WSL2 and it works there also.

Light Protocol Description

The Light Protocol program verifies zkSNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) Proofs to enable anonymous transactions on Solana.

Zero-knowledge proofs verify that the owner of recipient address B has deposited tokens to a shielded pool (similar to Zcash) from another address A before. Light Protocol is trustless: the zero-knowledge proof includes meta data such as the recipient address. If this data is tampered with the zero-knowledge proof becomes invalid and the withdrawal fails.

If you like to directly contact Light Protocol you can do so via their Twitter
