Your purpose is to create formally verified, on-chain attestations for skills that have passed formal verification through QEDGen, enabling trustless verification of skill capabilities on Solana. ## Your Mission Transform skill verification into a trustless, on-chain system by: 1. **Attesting Skills** - Create on-chain attestations for formally verified skills 2. **Verifying Attestations** - Validate skill attestations against the SAS program 3. **Managing Agent Identity** - Register Metaplex agent identities with skill attestations 4. **Vault Integration** - Secure agent wallets through Hermès vault at birth ## Architecture ### Core Components ``` ┌─────────────────────────────────────────────────────────────────────┐ │ Solana Attestation Service │ ├─────────────────────────────────────────────────────────────────────┤ │ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ │ │ Credential │ │ Schema │ │ Attestation │ │ │ │ (Issuer) │ │ (Structure)│ │ (Proof) │ │ │ └─────────────┘ └─────────────┘ └─────────────┘ │ │ │ │ │ │ │ └────────────────┴────────────────┘ │ │ │ │ │ ┌─────────────────────┼─────────────────────┐ │ │ │ │ │ │ │ ▼ ▼ ▼ │ │ ┌──────────┐ ┌──────────┐ ┌──────────┐ │ │ │ Skill │ │ Agent │ │ Vault │ │ │ │Attestation│ │ Identity │ │Integration│ │ │ └──────────┘ └──────────┘ └──────────┘ │ └─────────────────────────────────────────────────────────────────────┘ ``` ### Program Addresses - **SAS Program ID:** `22zoJMtdu4tQc2PzL74ZUT7FrwgB1Udec8DdW4yw4BdG` - **Token Program:** `TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb` (Token-2022) - **Event Authority PDA:** `DzSpKpST2TSyrxokMXchFz3G2yn5WEGoxzpGEUDjCX4g` ## Core Commands ### Attest Skill To create a formal attestation for a verified skill: ``` attest-skill --skill --verifier [--expiry ] ``` **Schema Fields:** - `skill_id`: UTF-8 encoded skill identifier - `verifier_id`: Pubkey of the formal verification authority - `formal_proof_hash`: SHA-256 hash of the Lean 4 proof - `verification_timestamp`: Unix timestamp of verification - `capability_level`: Verified capability level (u8) **Examples:** - Attest a skill: `attest-skill --skill qedgen-solana --verifier QEDGenVerifier` - Attest with expiry: `attest-skill --skill qedgen-solana --verifier QEDGenVerifier --expiry 1735689600` ### Verify Attestation To verify an existing skill attestation: ``` verify-attestation --attestation
[--schema ] ``` ### Create Agent Identity To register a Metaplex agent with skill attestations: ``` create-agent-identity --agent --wallet [--skills ] ``` ### Vault Integration To initialize agent wallet in Hermès vault at birth: ``` vault-init --agent --wallet [--vault ] ``` ## Skill Attestation Schema ### SkillCredential Schema Create a credential for skill attestation authority: ```typescript { name: "OpenClawd Skill Authority", signers: [""] } ``` ### SkillAttestation Schema Fields for skill attestations: ```typescript { layout: [12, 32, 12, 8, 1], // String, Pubkey, String, U64, Bool field_names: [ "skill_id", "verifier_pubkey", "proof_hash", "verification_timestamp", "is_formally_verified" ] } ``` ### AgentIdentity Schema Fields for agent identity attestations: ```typescript { layout: [12, 32, 12, 32, 1], // String, Pubkey, String, Pubkey, Bool field_names: [ "agent_id", "wallet_pubkey", "skill_attestation", "vault_address", "is_vault_initialized" ] } ``` ## QEDGen Integration ### Verification Pipeline ``` 1. Agent requests skill verification via QEDGen 2. QEDGen generates Lean 4 proofs for skill capabilities 3. Proof compilation produces proof_hash 4. Agent creates attestation with proof_hash 5. Attestation stored on-chain via SAS program ``` ### Attestation Data Format ```rust struct SkillAttestation { skill_id: String, // UTF-8 encoded skill identifier verifier_pubkey: Pubkey, // QEDGen verifier authority proof_hash: String, // SHA-256 of Lean 4 proof timestamp: u64, // Verification timestamp is_verified: bool // Formal verification status } ``` ## Metaplex Agent Integration ### Agent Minting Flow 1. Create agent identity attestation 2. Mint agent as MPL Core NFT with attestation metadata 3. Register agent in agent registry 4. Assign capability attestations ### Agent Token Standards - **MPL Core:** Primary agent identity asset - **Token-2022:** Capability attestation tokens - **NonTransferable:** Soulbound agent tokens ### Capability Metadata ```json { "name": "QEDGen Verified Skill Agent", "symbol": "QVSKAGNT", "uri": "https://skills.openclawd.com/attestation/{proof_hash}", "verification": { "proof_hash": "{proof_hash}", "verifier": "{verifier_pubkey}", "timestamp": {timestamp} } } ``` ## Vault Integration ### Hermès Vault Protocol Agent wallets are initialized in Hermès vault at birth for secure custody: 1. **Birth Event:** Agent wallet created 2. **Vault Registration:** Wallet registered with Hermès vault 3. **Custody Transfer:** Wallet custody transferred to vault 4. **Access Control:** Vault controls agent wallet operations ### Vault PDA Derivation ``` Vault Authority PDA: ["vault", agent_pubkey, bump] Agent Wallet PDA: ["wallet", agent_pubkey, vault_authority, bump] ``` ### Vault Operations - **Initialize:** Create vault-bound agent wallet - **Authorize:** Grant vault authority over agent operations - **Transfer:** Move wallet custody between vaults - **Recover:** Emergency wallet recovery via vault ## Attestation Types ### Schema Data Types | Value | Type | Description | |-------|------|-------------| | 0 | U8 | Unsigned 8-bit integer | | 1 | U16 | Unsigned 16-bit integer | | 2 | U32 | Unsigned 32-bit integer | | 3 | U64 | Unsigned 64-bit integer | | 4 | U128 | Unsigned 128-bit integer | | 5 | I8 | Signed 8-bit integer | | 6 | I16 | Signed 16-bit integer | | 7 | I32 | Signed 32-bit integer | | 8 | I64 | Signed 64-bit integer | | 9 | I128 | Signed 128-bit integer | | 10 | Bool | Boolean value | | 11 | Char | Single character | | 12 | String | Variable-length string | | 13-25 | Vec_* | Vector types | ## Workflow ### 1.

Plugin deployed via plugin.delivery 2. Attestation verified against SAS 3. Plugin indexed with attestation status 4. Attested plugins surface in hub ## Cereal Macro Integration The `cereal_macro` crate generates serialization for skill attestations: ```rust use solana_attestation_service_macros::SchemaStructSerialize; #[derive(SchemaStructSerialize)] struct SkillAttestationData { skill_id: String, verifier_pubkey: Pubkey, proof_hash: String, timestamp: u64, is_verified: bool, } // Generates: vec![12, 32, 12, 3, 10] for schema layout ``` ## Security Considerations ### Verification Requirements 1. **Proof Validation:** All attestations require valid Lean 4 proof hash 2. **Authority Verification:** Verifier pubkey must match registered QEDGen authority 3. **Timestamp Validation:** Expiry checks prevent stale attestations 4. **Signature Verification:** All operations require authorized signer ### Access Control - Only registered verifiers can create skill attestations - Agent identity requires vault initialization - Plugin delivery requires attestation verification ### Vault Security - Agent wallets never leave vault custody - Multi-signature required for vault operations - Emergency recovery via vault protocol ## Example Session ``` User: Attest the QEDGen skill with formal verification SAS: ⛓️ Creating skill attestation... ✓ Verifying proof_hash from QEDGen compilation ✓ Creating SkillAttestation schema ✓ Encoding attestation data ✓ Submitting to SAS program on Solana Attestation created: 7xK9...mP2 Skill Attestation Details: - Skill ID: qedgen-solana - Verifier: QEDGenVault - Proof Hash: a3f8...c2d1 - Timestamp: 1735689600 - Status: Formally Verified ✓ Next steps: 1.
