What is Chitin Cert?
Chitin Cert serves as the dedicated credential layer of the Chitin Protocol, enabling the issuance of verifiable credentials to any agent or wallet on Base L2. Each certificate is minted as a non-transferable NFT, ensuring a permanent and tamper-proof record stored on Arweave. This system is a vital component for developers looking to expand their Openclaw Skills with identity anchoring and verifiable history.
By providing a cryptographically secure way to prove capabilities and accomplishments, Chitin Cert allows for the creation of a trustless reputation layer. Whether you are certifying autonomous agents or human contributors, the platform ensures that every credential is authenticated by a registered issuer and is publicly verifiable via API or on-chain data.
Chitin Cert Use Cases
- Issuing milestones and achievement awards for decentralized hackathons or project wins.
- Certifying technical capabilities and verified skills for autonomous AI agents.
- Recording compliance, security audits, and regulatory approvals as permanent on-chain records.
- Establishing partnership endorsements and collaboration records between decentralized entities.
How Chitin Cert Works
- Issuer Registration: The entity signs a specific challenge message with their wallet to register as a trusted issuer.
- API Key Generation: A secondary signed message is used to generate a secure API key for programmatic certificate issuance.
- Certificate Minting: The issuer sends a request to the API to mint a certificate, which creates a non-transferable NFT on Base L2 and stores metadata on Arweave.
- Identity Binding: Certificates can optionally be linked to a Chitin Soul (SBT) or an ERC-8004 passport for deeper identity integration.
- Public Verification: Any third party can query the API or check the blockchain to verify the validity, issuer, and recipient of the certificate.
Chitin Cert Setup
To begin using this as part of your Openclaw Skills, you must first register as an issuer. This requires a wallet signature to prove ownership.
Step 1: Register Issuer
curl -X POST https://certs.chitin.id/api/v1/issuers \
-H "Content-Type: application/json" \
-d '{
"address": "0xYOUR_WALLET",
"name": "Your Organization",
"signature": "0x...",
"message": "Chitin Certs: Register issuer 0xyour_wallet at 1740000000000",
"timestamp": 1740000000000
}'
Step 2: Generate API Key
curl -X POST https://certs.chitin.id/api/v1/auth \
-H "Content-Type: application/json" \
-d '{
"issuerId": "YOUR_ISSUER_ID",
"name": "production-key",
"signature": "0x...",
"message": "Chitin Certs: Generate API key for YOUR_ISSUER_ID at 1740000000000",
"timestamp": 1740000000000
}'
Chitin Cert Data Schema & Taxonomy
Chitin Cert categorizes credentials into specific types to maintain a clean taxonomy within the Openclaw Skills directory:
| Type | Application |
|---|---|
| achievement | Milestones and major accomplishments |
| capability | Verified technical skills and abilities |
| compliance | Regulatory and security audit approvals |
| infrastructure | Deployment and uptime verifications |
| audit | Third-party code or process reviews |
Each certificate record includes tokenId, txHash, arweaveTxId, and metadata fields such as recipientAddress, evidence URLs, and optional expiresAt timestamps.
Chitin Cert Advanced Features
- Batch Issuance: Support for minting up to 100 certificates in a single transaction for high-volume operations.
- Soul-Linking: Deep integration with ChitinSoulRegistry to bind credentials to a permanent digital identity.
- Webhook Support: Real-time notifications for
cert.mintedevents to trigger automated downstream workflows. - MCP Server Integration: Native support for AI assistants to issue and verify certificates directly through standardized tool calls.
