Agent Passport Specification

The Sovereign Identity Standard for Autonomous Agents

1. Overview

In V3.1, Sovereign Swarm moves from a custom registry program to Solana Token-2022 native extensions. An “Agent Identity” is now a Non-Transferable (Soulbound) NFT minted directly to the agent’s wallet.

This approach ensures:

Composability: Any DeFi protocol can check amount > 0 to verify identity.
Portability: Identity travels with the wallet, recognized by all wallets/explorers.
Enforcement: Transfer Hooks on the Passport itself can prevent key rotation if compromised.

2. Technical Standard (Token-2022)

The Passport is a Mint Account with the following extensions enabled:

Extension	Purpose
Non-Transferable	Makes the token “Soulbound”. It cannot be moved from the agent’s wallet.
Metadata Pointer	Points to on-chain metadata (Status, Tier) and off-chain proofs.
Permanent Delegate	Allows the Jurisdiction (DAO) to burn/revoke identity in case of Constitutional Violation.

3. Metadata Schema

The Passport stores critical jurisdictional data directly in the Token Extensions metadata:

On-Chain Fields

Field	Type	Description
`name`	String	Agent’s legal/governance name
`jurisdiction_status`	String	`Active`, `Suspended`, `Blacklisted`
`kya_tier`	String	`Verified`, `Institutional` (See KYA_SPEC)
`operator_did`	String	DID of the liable human operator (optional/ZK)
`policy_id`	Pubkey	Address of the Insurance Policy (Risk Vault)

Off-Chain (Arweave)

Full “Articles of Incorporation”
Operator contact details (encrypted)
Capability Manifest (what code is running)
Source Code Hash (Git SHA)

4. Lifecycle

A. Incorporation (Minting)

Agent generates a fresh Solana Keypair.
Operator submits incorporate transaction with:
- Metadata (Name, Operator DID)
- $GRID Stake (if applicable)
Protocol mints 1 Passport Token to Agent Wallet.
Token is permanently locked to that wallet.

B. Verification (Gating)

DeFi protocols or other Agents check for the Passport:

// Check if wallet holds the Sovereign Passport
if passport_balance == 1 && metadata.status == "Active" {
    allow_interaction();
} else {
    block_interaction();
}

C. Sanction (Suspension)

If the Constitutional Arbitration or Parametric Trigger detects a violation:

Protocol calls update_metadata(status="Suspended").
Transfer Hooks on the $GRID Token refer to this Passport.
If Passport.status == Suspended, the agent cannot move funds.

5. Why Token-2022?

Legacy identity systems (like V2.3) used custom programs that required custom SDKs to read. By using Token-2022, the Agent Passport is visible in:

Phantom / Solflare
Solana Explorer
Squads Multisig

It makes the agent a first-class citizen of the Solana blockchain.
