Compile the contracts

npx hardhat compile

Test the contracts

Measure code coverage

npx hardhat coverage

Run tests

Using the gas reporter:

REPORT_GAS=true npx hardhat test

Running the tests in parallel

npx hardhat test --parallel

Compile the contracts

npx hardhat compile

Deploy the contracts

You can deploy in the localhost network following these steps:

  1. Start a local node
npx hardhat node
  1. Deploy the Ignition module
npx hardhat ignition deploy ./ignition/modules/CredentialRegistry.ts --network localhost
  1. Run an interact script
npm run interact

This runs the script in scripts/interact.ts which has an example code on how the register and verify methods work.

Verify the contracts

When you deploy to a testnet or mainnet, you probably want to verify the contract at the same time for which you can do:

npx hardhat ignition deploy ignition/modules/CredentialRegistry.ts --network base_sepolia --deployment-id base_sepolia_deployment --verify

Contract Info

  • CredentialMetadata Struct: Holds information about a registered credential.
  • Mappings: Stores issuer-to-credential IDs, recipient DID-to-credential IDs, credential type-to-credential IDs, and issued/received credential counts.
  • registerCredential Function:
    • Checks if the credential ID is already registered.
    • Stores the credential metadata.
    • Updates issuer, recipient, and type-based mappings.
    • Emits a CredentialRegistered event.
  • Getter Functions:
    • getCredentialsByIssuer: Retrieves credentials issued by a specific address.
    • getCredentialsByRecipient: Retrieves credentials associated with a recipient DID.
    • getCredentialsByType: Retrieves credentials of a specific type.
  • verifyCredential Function:
    • Checks if the credential ID exists.
    • Uses verifyEvmDid for Ethereum-based DIDs (optional for other DID methods).
    • Emits a CredentialVerified event if the signature is valid.
  • verifyEvmDid Function:
    • Extracts the address from the DID (assuming Ethereum DID format).
    • Calculates the message hash as expected by the contract (including the Ethereum Signed Message prefix).
    • Recovers the signer's address using ecrecover.
    • Compares the recovered address with the recipient address and returns it if valid.
