shell-contracts

Smart contracts for shell.

Development

Install dependencies:

yarn

Compile all artifacts and generate typechain types:

yarn build

Run unit tests:

yarn test

Run unit tests showing gas usage by function and deploy costs:

REPORT_GAS=1 yarn test

Run unit tests and report coverage:

yarn test:coverage

If you have shell-subgraph and shell-frontend repos as sibling directories to this one, you can copy built ABIs to the appropriate location in those repos:

./copy-pasta-abis.sh

Deployment

Copy .env.example to .env and override the default values before deploying.

Deploy a contract (eg, ShellFactory):

yarn deploy --network rinkeby --contract ShellFactory

This will output the deployed contract address in the console and update the ./tasks/deployments.json file.

NOTE: The contract will automatically be verified on etherscan

Deploying Implementations

To deploy a token model / implementation and register it with the corresponding shell factory:

yarn deploy:implementation --network rinkeby --contract ShellERC721 --implementation erc721-v1

This will deploy and verify the contract, as well as call the register method on the factory. This won't work if factory ownership has been transferred to a non-dev wallet.

To register an existing deployment:

yarn register --network rinkeby --address 0x123..123 --implementation erc721-prototype

Verification

The deploy task will automatically verify contracts generally.

This can occasionally fail. If it does, verify manually:

yarn verify --network rinkeby $CONTRACT_ADDRESS

Verification may fail if run too quickly after contract deployment.

If you are verifying for polygon or mumbai networks, set the POLYGON env var:

POLYGON=1 yarn verify --network polygon $CONTRACT_ADDRESS

If you are verifying for the arbitrum or arbitrum-rinkeby network, set the ARBITRUM env var:

ARBITRUM=1 yarn verify --network arbitrum $CONTRACT_ADDRESS

If you are verifying for the fantom network, set the FANTOM env var:

FANTOM=1 yarn verify --network fantom $CONTRACT_ADDRESS

Publishing
