main is the development branch. Application developers should use the latest release instead.

RISC Zero Ethereum

RISC Zero is a zero-knowledge verifiable general computing platform, with Ethereum integration. This repository contains Solidity verifier contracts, Steel EVM view call library, and supporting code.

If you are looking to get started using RISC Zero in the application on Ethereum, the best place to look is the Foundry template.

You can also find the documentation for RISC Zero, including guides for writing zkVM programs, using the Bonsai prover, and more at dev.risczero.com.

Contracts

RISC Zero's Ethereum contracts, including the on-chain verifier for all RISC Zero Groth16 proofs, can be found in the contracts directory.

Steel

A powerful library for querying and generating verifiable proofs over Ethereum or other EVM-based blockchain state. It leverages alloy, giving developers a familiar and high quality interface for querying Ethereum via view calls. By moving execution off-chain, Steel significantly reduces gas costs and enables novel Ethereum use cases without compromising security.

You can install Steel with cargo add risc0-steel, check out the examples in the examples directory.
