Email Wallet Monorepo

This is a monorepo for the Email Wallet project, which includes several components:

• Circuits
• Utils
• Relayer
• Prover

Components

Circuits

Contains the zero-knowledge circuits used in the Email Wallet system.

Utils

Utility functions and helper modules for the project.

Relayer

The relayer component of the Email Wallet system.

Prover

A fast prover implementation for generating zkSNARK proofs.

Getting Started

To build the prover, run the following command:

yarn build:prover

Building rapidsnark with GPU support

You'll need NVIDIA GPU drivers and CUDA toolkit installed. Following is for debian based systems.

Note: docekr desktop on Linux and Mac does not support GPU passthrough. You'll need to use docker engine on Linux for GPU passthrough.
