Linting smart contracts

1. solhint "contracts/**/*.sol"

Deploying

Adding completely new instances for a first time

1. deploy both:
   • VerifierRegistryStorage.sol
   • VerifierRegistry.sol
2. validate code for both contracts, use truffle-flattener to help:
   • truffle-flattener ./contracts/VerifierRegistryStorage.sol > all_storage.sol
   • truffle-flattener ./contracts/VerifierRegistry.sol > all.sol
3. connect storage:
   • go to storage contract and call initStorageOwner()
   • to verify that you connected storage properly, go to registry contract and call any read method - if its throw, means you failed with initiation of storage.
4. add it to the ContractRegistry:
   • call ContractRegistry.add() providing your contract address.
   • verify process by calling ContractRegistry.contractByName() to see if contract is registered.

Example:

const ContractRegistry = artifacts.require('ContractRegistry');
const contractRegistry = await ContractRegistry.at(config.ContractRegistry.address);
await contractRegistry.add(VerifierRegistry.address);
