Install

yarn install

Test

Testing uses the Hardhat framework

To run all tests

yarn test

To run individual test files, use

npx hardhat test <PATH_TO_TEST>

Deployment

Hardhat does not support native deployments. To aid in deployment, hardhat-deploy is being used. You can see the deployment scripts in the /deploy directory.

To run deploys

npx hardhat deploy

This will run all deployments.

Scripts have also been created to run deployments and add supporting function calls. For example, DeployAndAddTracer.js runs the FullDeploy.js file and then creates a Tracer market with this deployment.

To run a specific script, run

npx hardhat run <PATH_TO_SCRIPT>

Migrations

TODO PATCH THIS WITH HARDHAT

To deploy to Kovan

1. Add a file called kovan.secret, including only your Kovan RPC endpoint.
2. Add a file called mnemonic.secret, including only the mnemonic of the account which you want to deploy from. This account must have enough KETH.
3. Add a file called priv_key.secret, including the private key of the account which you want to deploy from (the same as from step 2).
4. Change numAccounts in the migrations-ts/2_deploy_contracts.ts.
5. Run yarn compile:migrations && yarn migrate --reset --network kovan.

• This may take a while, depending on how big numAccounts is.
• The private keys of the newly generated accounts are output to ./private_keys.txt

To deploy to development (localhost)

1. Run ganache-cli -l 80000000000
2. In a separate window, run yarn compile:migrations && yarn migrate --reset --network development
3. There will be errors when trying to read from different files required for Kovan deployment. You can safely ignore these.
