Chainlink CRE workflows for the SAVE Proof of Reserves framework. Contains both the attestation and verification workflows.
Pre-configured with mHYPER as default example. To use with another token, update fundManager.tokenName and the relevant proofId/claimType in the config.
Listens for NewClaim events on the SaveRegistryWithClaim contract, verifies claim data via Vlayer TLS Notary proof, creates a signed attestation with structured claims, and pushes it on-chain.
Flow: NewClaim event → Fetch from IPFS → Vlayer verification (BFT consensus) → Build claims → Sign attestation → Upload to IPFS → setAttestation on-chain
Listens for AttestationSet events, fetches and decompresses the attestation from IPFS, re-verifies the TLS Notary proof via Vlayer, validates all claims, and pushes a verification hash on-chain.
Flow: AttestationSet event → Fetch from IPFS → Vlayer re-verification (BFT consensus) → Validate claims → Upload verification → setVerification on-chain
The config templates come pre-filled with mHYPER POR values:
| Field | Value |
|---|---|
| Registry | 0x2D6e9F608807436DE5D9603B00Abe3FEd1Bc809d (mainnet) |
| ProofId | 0xAC9A528065AFB4290AB62FB0EE1A9110D48ED834454D2D04AB369B4832BBDA7A |
| Fund manager email | mhyper@hyperithm.com |
| Token name | mHYPER |
To adapt for another token, change the proofId in topics, fundManager.tokenName, fundManager.expectedEmail, and the claim type hash.
- Chainlink CRE CLI
- Bun runtime
- An Ethereum RPC endpoint
- IPFS node with Kubo RPC API (Basic Auth) — or modify the code to use Pinata
- Vlayer API access (contact Vlayer for
client_idandauth_token) - Your wallet must be authorized on the registry:
- Attestation:
setAttestor(proofId, address) - Verification:
authorizeVerifiers(proofId, [address])
- Attestation:
cd cre/attestation # or cre/verification
