Thank you for your interest in contributing to RISC Zero! We welcome contributions from everyone.
If you have any questions about contributing, or about the project in general, please ask in our Discord channel.
To run the test suite, the following dependencies are needed:
Once installed, run:
git lfs install
git lfs pull
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
The RISC Zero toolchain must match the version of crates you are compiling.
When testing and running examples within this library, you can install cargo-risczero
from source:
cargo install --force --path risc0/cargo-risczero
Otherwise, if using a stable version branch, you can install cargo-risczero
through the standard flow:
curl -L https://risczero.com/install | bash
rzup install
Optionally, you can specify which version of cargo-risczero
to install with:
rzup install --version $VERSION
NOTE: It is only important that you install
cargo-risczero
with a matching version of thezkvm
crate when interacting with the proof system as a separate, pre-built process (ExternalProver
), which is currently the default. If you are using theprove
feature on therisc0-zkvm
crate for the host, this will compile the proving system into the host binary.
xtask wasm tools (if testing browser-verify)
cargo xtask install
cargo xtask gen-receipt
