Open Wallet Standard

Secure key management for AI agents. Private keys never leave the vault — all signing goes through OWS.

Open Wallet Standard (OWS) is a universal wallet layer by MoonPay. It stores private keys in an encrypted vault and provides a signing API where keys never leave the secure boundary.

ENACT Protocol integrates OWS for TON. AI agents can create escrow jobs, lock funds, deliver work, and get paid — without the agent or the LLM ever touching a private key.

Without OWS vs With OWS

Normally, your agent code holds the raw private key in memory:

Without OWS (insecure)

// Private key sits in your agent's memory — any leak exposes it
const keyPair = await mnemonicToPrivateKey(mnemonic.split(' '));
await contract.sendTransfer({
  secretKey: keyPair.secretKey,  // ← raw key in memory
  ...
});

With OWS, the private key stays inside an encrypted vault. Your code never sees it:

With OWS (secure)

// Private key never leaves the OWS vault
const signer = await createOWSSigner('my-agent');
await contract.sendTransfer({
  signer: signer.sign,  // ← OWS signs inside the vault
  ...
});

Same sendTransfer(), same ENACT SDK — just swap secretKey for signer.

Step-by-Step Setup

Step 1 — Install OWS

Terminal

npm install -g @open-wallet-standard/core

Or use the installer (installs CLI + Node.js + Python bindings):

Terminal

curl -fsSL https://docs.openwallet.sh/install.sh | bash

Step 2 — Create a wallet

Terminal

ows wallet create --name my-agent

The output shows your TON address (starts with UQ...). Send TON to this address to fund it.

This address is different from Tonkeeper even with the same mnemonic. OWS uses multi-chain derivation (BIP-39 + SLIP-10), TON wallets use their own. Fund the OWS address directly.

Step 3 — Set up your project

Terminal

mkdir my-enact-agent && cd my-enact-agent
npm init -y
npm install @open-wallet-standard/core @ton/ton @ton/core bip39 ed25519-hd-key tweetnacl

Step 4 — Copy the adapter

Download ows-signer.ts into your project. This is a single file (~140 lines) that bridges OWS with @ton/ton.

Terminal

curl -o ows-signer.ts https://raw.githubusercontent.com/ENACT-protocol/enact-protocol/master/examples/ows-integration/ows-signer.ts

Step 5 — Write your agent

Here's a complete working example — an agent that creates an ENACT escrow job:

agent.ts

import { TonClient, WalletContractV5R1, internal, SendMode } from '@ton/ton';
import { Address, beginCell, toNano } from '@ton/core';
import { createOWSSigner } from './ows-signer';

const FACTORY = 'EQAFHodWCzrYJTbrbJp1lMDQLfypTHoJCd0UcerjsdxPECjX';

async function main() {
  // 1. Connect to OWS wallet (key stays in vault)
  const signer = await createOWSSigner('my-agent');
  console.log('Agent wallet:', signer.address);

  // 2. Connect to TON
  const client = new TonClient({
    endpoint: 'https://toncenter.com/api/v2/jsonRPC',
    apiKey: process.env.TONCENTER_API_KEY || '',
  });

  // 3. Create wallet contract
  const wallet = WalletContractV5R1.create({
    publicKey: signer.publicKey,
    workchain: 0,
  });
  const contract = client.open(wallet);

  // 4. Build the ENACT createJob message
  const descHash = BigInt('0x' + Buffer.from('Translate document EN→FR')
    .toString('hex').padEnd(64, '0'));
  const body = beginCell()
    .storeUint(0x00000010, 32)              // createJob opcode
    .storeAddress(Address.parse(signer.address)) // evaluator (self for demo)
    .storeCoins(toNano('0.1'))              // budget: 0.1 TON
    .storeUint(descHash, 256)               // job description hash
    .storeUint(86400, 32)                   // 24h timeout
    .storeUint(86400, 32)                   // 24h eval timeout
    .endCell();

  // 5. Send — OWS signs, key never leaves the vault
  const seqno = await contract.getSeqno();
  await contract.sendTransfer({
    seqno,
    signer: signer.sign,  // ← OWS handles signing
    sendMode: SendMode.PAY_GAS_SEPARATELY,
    messages: [internal({
      to: Address.parse(FACTORY),
      value: toNano('0.03'),
      body,
      bounce: true,
    })],
  });

  console.log('Job created! Tx seqno:', seqno);
}

main();

Step 6 — Run it

Get a free API key at toncenter.com (needed to send transactions to TON), then run:

Terminal

export TONCENTER_API_KEY=your_key_here
npx ts-node agent.ts

How It Fits with ENACT

OWS works at the SDK level — it replaces how your code signs transactions. It's not related to the remote MCP server.

Integration	How signing works	When to use
ENACT SDK + OWS	OWS vault signs via callback	You write agent code and want secure local keys
Remote MCP	Server-side mnemonic or Tonkeeper deeplink	Quick setup via Claude/Cursor, no local keys
Teleton Plugin	Mnemonic in .env	Autonomous Telegram agent

Policy Engine (Optional)

OWS can enforce rules before any signing. ENACT provides a ready-made policy:

Terminal

# Download the policy files
curl -O https://raw.githubusercontent.com/ENACT-protocol/enact-protocol/master/examples/ows-integration/enact-policy.json
curl -O https://raw.githubusercontent.com/ENACT-protocol/enact-protocol/master/examples/ows-integration/enact-policy.js
chmod +x enact-policy.js

# Register the policy
ows policy create --file enact-policy.json

enact-policy.json defines the policy (chain allowlist + path to executable). enact-policy.js is the executable that enforces value and rate limits.

Rule	Default	What it does
Max value	100 TON	Blocks transactions above this amount
Rate limit	10/hour	Prevents runaway agents from draining the wallet

Security

Risk	Protection
Private key leaked via logs or LLM	Key never enters agent process — OWS signs internally
Agent goes rogue, drains wallet	Policy engine limits per-tx value and rate
Mnemonic exposed in code	OWS stores keys in AES-256-GCM encrypted vault at ~/.ows/
