Interep Solidity smart contracts.

Please, visit our web app or our documentation website for more details.

Clone this repository and install the dependencies:

git clone https://github.com/interep-project/contracts.git
cd contracts
yarn # or `npm i`

Copy the .env.example file and rename it .env.

Compile the smart contracts with Hardhat:

yarn compile

Lint the Solidity or the TypeScript code:

yarn lint:sol
yarn lint:ts
# or yarn lint to lint both.

And check if the code is well formatted:

yarn prettier

Run the Mocha tests:

yarn test

Generate the code coverage report:

yarn test:coverage

See the gas usage per unit test and average gas per method call:

yarn test:report-gas

Deploy a Semaphore verifier contract with depth = 20:

yarn deploy:verifier # The resulting address will have to be used in the next step.

Deploy the Interep contract with one Semaphore verifier:

yarn deploy --verifiers '[[20, "0x5FbDB2315678afecb367f032d93F642f64180aa3"]]'

If you want to deploy contracts 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, ropsten, kovan, arbitrum). Or you can specify it as option:

yarn deploy --verifiers '[[20, "0x06bcD633988c1CE7Bd134DbE2C12119b6f3E4bD1"]]' --network kovan
yarn deploy --verifiers '[[20, "0x5FbDB2315678afecb367f032d93F642f64180aa3"]]' --network localhost

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

Run a Hardhat Network in a stand-alone fashion:

yarn start

Deploy a Semaphore verifier and the Interep contract:

yarn deploy:verifier --network localhost
yarn deploy --verifiers '[[20, "0x5FbDB2315678afecb367f032d93F642f64180aa3"]]' --network localhost

You can omit --network localhost if your DEFAULT_NETWORK env variable is equal to localhost.
