Build From Source

Dependencies

dep	version
Node.js	>=v14.0.0

Building

Install dependencies:

npm ci

Build and run tests:

npm run build
npm test

Deployed Contract Addresses

You can find the addresses of the currently deployed contracts in the deployment files:

• Mainnet - TBD
• Goerli - deployments.goerli.json

*Note: the contracts may have source code different from the current master branch head. Refer to the code verification on Etherscan or Sourcify for a look at their verified source code.

Scripts

There are several provided scripts to help with contract management. Before running the scripts, make sure your environment variables are correctly configured. You can optionally create a .env file to set these variables (see .env.example). The following is a list of the common variables to set:

• ETHERSCAN_API_KEY - Etherscan API key (required for code verification steps)
• CONTRACTS_RPC_URL - Overrides the default script used network RPC URL when set
• CONTRACTS_DEPLOYER_KEY - Overrides the default script used network accounts when set
• CONTRACTS_GAS_PRICE - Overrides the default script used network gas price when set

Deploy All

npm run script-deploy

Deploys ALL contracts including proxy contracts. This is most useful when running a local network that you wish to deploy the full contract set to for testing.

Upgrade All

npm run script-upgrade

Upgrades ALL contracts with new implementations. This is only possible if the current owner of the contracts is also the default deployer for the network. This is most useful when running a local network that you wish to upgrade the full contract set to for testing.

Deploy Implementations

npm run script-deploy-impl

Deploys new implementation contracts. This is most useful in preparation for proposing a contract upgrade where the proxy contract owner is a multisig.

Verify Source

npm run script-verify-source

Verifies the contract source code on Etherscan and Sourcify. This is only possible on recognized public networks (goerli, mainnet) and requires a deployment file either added manually under the deployments directory or auto generated after the deploy/upgrade scripts. This is useful to run in case there was an issue verifying the source during the deploy or updgrade scripts.

Verify Address

npm run script-verify-address

Verifies the given contract address source code on Etherscan and Sourcify. This is useful to test if a proposed upgrade implementation exactly matches the expected code currently in the repository or on a specific branch of the repository. It also publicly verifies the source code of the given contract on Etherscan and Sourcify in the process. Note that this script checks the bytecode at the address against the repository first before uploading to Etherscan so you would see an error in regards to that first before anything about publicly verifying.

Contributing

Code must pass tests with 100% coverage as well as be formatted and linted.

npm run coverage
