📜 Usage

Testing

Run Mocha to test the contracts:

yarn test

You can also generate a test coverage report:

yarn test:coverage

Or a test gas report:

yarn test:report-gas

Deploy contracts

Deploy the Semaphore.sol contract without any parameter:

yarn deploy:semaphore

or deploy it by providing the addresses of the contracts/libraries on which it depends:

yarn deploy:semaphore --semaphoreVerifier <address>

Note
Run yarn deploy:semaphore --help to see the complete list.

If you want to deploy your contract in a specific network you can set up the DEFAULT_NETWORK variable in your .env file with the name of one of our supported networks (hardhat, localhost, goerli, arbitrum). Or you can specify it as an option:

yarn deploy:semaphore --network goerli
yarn deploy:semaphore --network arbitrum

If you want to deploy contracts on Goerli or Arbitrum, remember to provide a valid private key and an Infura API in your .env file.
