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:
wasm
and zkey
filesVerifier.sol
See the source projects for full documentation and configuration
yarn
to install dependencies
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
.
yarn circom:prod
for production builds (using Date.now()
as entropy)
