@brainai/satp-v3

Solana Agent Token Protocol V3 — TypeScript SDK

On-chain identity, reputation, reviews, attestations, and validation for AI agents on Solana.

Install

npm install @brainai/satp-v3 @solana/web3.js

Quick Start

import { SatpV3Client, resolveAgent, trustTier } from '@brainai/satp-v3';

// Initialize client
const client = new SatpV3Client('https://api.devnet.solana.com');

// Resolve agent → on-chain PDA
const pda = resolveAgent('agent_brainforge');
console.log('PDA:', pda.toBase58());

// Check if agent exists on-chain
const exists = await client.agentExists('agent_brainforge');

// Get full agent summary
const summary = await client.getAgentSummary('agent_brainforge');
console.log(summary);
// { exists: true, pda: PublicKey, reviewCount: 3, linkedWalletCount: 1 }

DID Resolution

import { resolveDid } from '@brainai/satp-v3/did';

const didDoc = await resolveDid('did:agentfolio:agent_brainforge', {
  rpcUrl: 'https://api.devnet.solana.com'
});

PDA Derivation

All PDA seeds match the on-chain programs exactly:

import {
  deriveGenesisPda,
  deriveLinkedWalletPda,
  deriveReviewPda,
  deriveAttestationPda,
  deriveNameRegistryPda,
  deriveMintTrackerPda,
  deriveReputationAuthorityPda,
  deriveValidationAuthorityPda,
} from '@brainai/satp-v3';

const [genesisPda, bump] = deriveGenesisPda('agent_brainforge');
const [namePda] = deriveNameRegistryPda('brainForge');

Utilities

import {
  reputationPct, verificationLabel, trustTier, isBorn,
  isAttestationValid, attestationTypeLabel,
  escrowStatusLabel, escrowRemaining, isEscrowExpired
} from '@brainai/satp-v3';

// Reputation score → percentage
reputationPct(genesisRecord); // "45.50"

// Verification level → label
verificationLabel(3); // "Enhanced"

// Trust tier from score
trustTier(350); // { tier: "L4", label: "Established" }

// Attestation validation
isAttestationValid(attestation); // true if verified + non-revoked + non-expired
attestationTypeLabel("github"); // "GitHub Identity"

// Escrow utilities
escrowStatusLabel(EscrowStatus.Active); // "Active"
escrowRemaining(escrow); // lamports remaining
isEscrowExpired(escrow); // true if past deadline

Trust Profile (one call → full picture)

const profile = await client.getTrustProfile('agent_brainforge');
// {
//   exists: true,
//   pda: PublicKey,
//   verificationLevel: { level: 3, label: "Enhanced" },
//   attestationSummary: { total: 5, verified: 4, valid: 3, uniqueTypes: ["github", "kyc"] },
//   reviewCount: 12,
//   linkedWalletCount: 2
// }

Transaction Builders (NEW in 3.5.0)

Build unsigned transactions for all SATP V3 instructions. Sign with any wallet adapter.

import { SatpV3Builders, LAMPORTS_PER_SOL } from '@brainai/satp-v3';

const builders = new SatpV3Builders('https://api.devnet.solana.com');

// Create an agent identity
const tx = await builders.createIdentity({
  agentId: 'agent_mybot',
  name: 'MyBot',
  description: 'An autonomous trading assistant',
  category: 'finance',
  capabilities: ['trading', 'analysis'],
  metadataUri: 'https://example.com/meta.json',
  creator: walletPublicKey,
});
// Sign and send: await connection.sendTransaction(tx, [walletKeypair]);

// Create an escrow (client pays agent for work)
const { transaction, escrowPda, nonce } = await builders.createEscrow({
  client: clientWallet,
  agentWallet: agentWallet,
  agentId: 'agent_mybot',
  arbiter: arbiterWallet,
  amount: 1_000_000_000n, // 1 SOL
  description: 'Build a trading bot',
  deadline: Math.floor(Date.now() / 1000) + 86400, // 24h
});

// Agent submits work proof
const submitTx = await builders.submitWork({
  escrowPda,
  agent: agentWallet,
  workProof: 'https://github.com/org/repo/pull/42',
});

// Client releases funds
const releaseTx = await builders.releaseEscrow({
  escrowPda,
  client: clientWallet,
  agent: agentWallet,
});

// Create a review
const reviewTx = await builders.createReview({
  agentId: 'agent_mybot',
  reviewer: reviewerWallet,
  rating: 5,
  reviewText: 'Excellent work, fast delivery!',
});

// Create an attestation (KYC, GitHub, etc.)
const attTx = await builders.createAttestation({
  agentId: 'agent_mybot',
  issuer: issuerWallet,
  attestationType: 'github',
  proofData: 'https://github.com/user',
  expiresAt: Math.floor(Date.now() / 1000) + 365 * 86400, // 1 year
});

Parse raw on-chain account data into typed TypeScript objects:

import {
  deserializeGenesis,
  deserializeLinkedWallet,
  deserializeReview,
  deserializeAttestation,
  deserializeEscrow,
  tryDeserialize,
} from '@brainai/satp-v3';

// Fetch raw data and deserialize
const raw = await client.getGenesis('agent_brainforge');
if (raw) {
  const genesis = deserializeGenesis(raw.data);
  console.log(genesis.agentName);         // "brainForge"
  console.log(genesis.verificationLevel); // 3
  console.log(genesis.isActive);          // true
}

// Batch-safe: tryDeserialize returns null instead of throwing
const reviews = await client.getReviews('agent_brainforge');
const parsed = reviews
  .map(r => tryDeserialize(deserializeReview, r.data))
  .filter(Boolean);
