circom-starter

A basic circom project using Hardhat and hardhat-circom. This combines the multiple steps of the Circom and SnarkJS workflow into your Hardhat workflow.

By providing configuration containing your Phase 1 Powers of Tau and circuits, this plugin will:

1. Compile the circuits
2. Apply the final beacon
3. Output your wasm and zkey files
4. Generate and output a Verifier.sol

Install

yarn to install dependencies

Development builds

yarn circom:dev to build deterministic development circuits.

Further, for debugging purposes, you may wish to inspect the intermediate files. This is possible with the --debug flag which the circom:dev task enables by default. You'll find them (by default) in artifacts/circom/

To build a single circuit during development, you can use the --circuit CLI parameter. For example, if you make a change to hash.circom and you want to only rebuild that, you can run yarn circom:dev --circuit hash.

Production builds

yarn circom:prod for production builds (using Date.now() as entropy)
