Verifiable Credential Verifier AVS

This is a proof of concept for a Credential Verifier built as an EigenLayer Actively Validated Service (AVS).

Key features and goals:

• Clients (subjects, issuers, etc.) can verify JWT credentials, establishing their verification on chain and enhancing the issuers' reputation.
• AVS operators verify credentials off-chain and pass necessary data to the AVS contract, where the credential signature is checked against the issuer's public key (converted to an Ethereum address equivalent).
• Further data about the issuer, subject and credential can be written on chain.
• A public track record of issuer claims can be established.

Development

Requirements

• Foundry

Setup and Run

1. Install Dependencies:

   ./bin/install_dependencies.sh

2. Start Anvil: In a separate terminal window, run:

   anvil

3. Deploy Contracts and Register Operator:

   ./bin/deploy_and_register.sh

4. Run Operator:

   npx tsx operator/index.ts

5. Create a Task: Once the setup is complete, you can create a task by running:

   npx tsx operator/createTask.ts

Updating the TypeScript ABI

If updating CredentialVerifierServiceManager.sol, update the TypeScript ABI after running forge build.

Make sure jq is installed locally, then run:

./bin/update_service_manager_abi.sh
