Custodian integration for native and web wallets

This document provides instructions for integrating TON Connect into wallets and other custodian services for iOS, Android, macOS, Windows, Linux, and Web platforms. TON Connect is the standard wallet connection protocol for The Open Network (TON) blockchain, similar to WalletConnect on Ethereum. It enables secure communication between wallets and decentralized applications, allowing users to authorize transactions while maintaining control of their private keys.

TON Connect bridge

The TON Connect bridge serves as a transport mechanism for delivering messages between applications (dApps) and wallets. It enables end-to-end encrypted communication where neither party needs to be online simultaneously.

Setup options

Option 1: On-premise solution

Custodians can run the TON Connect Bridge themselves. This approach provides full control over the infrastructure and data. For this option, you can deploy the official TON Connect Bridge implementation. You will need to:

Set up a dedicated bridge instance following the repository documentation
Create a DNS entry pointing to your bridge
Configure your infrastructure (load balancers, SSL certificates, etc.)
Maintain the bridge and provide updates

Option 2: SaaS solution

TON Foundation can provide a Software-as-a-Service (SaaS) solution for custodians who prefer not to maintain on-premise infrastructure. To request access to the SaaS solution, contact the TON Foundation business development team. This managed service includes:

Hosted bridge infrastructure
Maintenance and updates
Technical support
Service level agreements

Bridge endpoints and protocol

The TON Connect Bridge protocol uses these main endpoints:

SSE Events Channel — For receiving messages:

GET /events?client_id=<to_hex_str(A1)>,<to_hex_str(A2)>,<to_hex_str(A3)>&last_event_id=<lastEventId>
Accept: text/event-stream

Message Sending — For sending messages:

POST /message?client_id=<sender_id>&to=<recipient_id>&ttl=300
body: <base64_encoded_message>

There, client_id and sender_id are the public keys of the wallet’s session in hex. To read more about the bridge protocol, please refer to the TON Connect Bridge documentation.

TON Connect protocol

TON Connect enables communication between wallets and dApps. For custodian wallets, the integration has these core components:

Establishing secure sessions with dApps
Handling universal links in the browser
Managing wallet connections
Listening for messages from connected dApps
Disconnecting from dApps

Setting up the protocol

We recommend using the @tonconnect/protocol package to handle the TON Connect protocol. But you can also implement the protocol manually.

npm install @tonconnect/protocol

Refer to the @tonconnect/protocol documentation for more details.

Session management and encryption

The foundation of TON Connect is secure communication using the SessionCrypto class:

import { SessionCrypto, KeyPair, AppRequest, Base64 } from '@tonconnect/protocol';

// Receive dApp public key from the connection link 'id' parameter
// This value is decoded from hex to Uint8Array
const dAppPublicKey: Uint8Array = hexToByteArray(dAppClientId);

// Create a new session - this generates a keypair for the session internally
const sessionCrypto: SessionCrypto = new SessionCrypto();

// Encrypt a message to send to the dApp
// Parameters:
// - message: The string message to encrypt
// - dAppPublicKey: The dApp's public key as Uint8Array
const message: string = JSON.stringify({
  event: 'connect',
  payload: { /* connection details */ }
});
const encryptedMessage: string = sessionCrypto.encrypt(
  message,
  dAppPublicKey
);

// Decrypt a message from the dApp
// Parameters:
// - encrypted: The encrypted message string from the dApp
// - dAppPublicKey: The dApp's public key as Uint8Array
const encrypted: string = 'encrypted_message_from_dapp';
const decryptedMessage: string = sessionCrypto.decrypt(
  Base64.decode(encrypted).toUint8Array(),
  dAppPublicKey
);
const parsedMessage: AppRequest = JSON.parse(decryptedMessage);

// Get session keys for storage
// Returns an object with `publicKey` and `secretKey` as hex strings
const keyPair: KeyPair = sessionCrypto.stringifyKeypair();

// Store these securely in your persistent storage
const storedData = {
  secretKey: keyPair.secretKey,
  publicKey: keyPair.publicKey,
  dAppClientId: dAppClientId
};

// Later - restore the session using stored keys
// Parameters:
// - secretKey: Hex string of the secret key
// - publicKey: Hex string of the public key
const restoredSessionCrypto: SessionCrypto = new SessionCrypto({
  secretKey: storedData.secretKey,
  publicKey: storedData.publicKey
});

Refer to the SessionCrypto implementation and Session documentation for more details.

Bridge communication

TON Connect uses a bridge service as a relay for messages between dApps and wallets:

// Bridge URL for your wallet
const bridgeUrl = 'https://bridge.[custodian].com/bridge';

// Sending messages to the bridge
// Parameters:
// - fromClientId: Your wallet's client ID (public key of the wallet's session in hex)
// - toClientId: The dApp's client ID (public key of the dApp's session in hex)
// - encryptedMessage: The encrypted message to send
// - ttl: Time to live in seconds (optional, default is 300 seconds)
async function sendToBridge(fromClientId: string, toClientId: string, encryptedMessage: string) {
  await fetch(`${bridgeUrl}/message`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      client_id: fromClientId,
      to: toClientId,
      message: encryptedMessage,
      ttl: 300
    })
  });
}

// Listening for messages from the bridge
// Parameters:
// - clientId: Your wallet's client ID (public key of the wallet's session in hex)
// - lastEventId: The last event ID received from the bridge (optional, but should be used if you want to resume listening for messages from the same point)
function listenFromBridge(clientId: string, lastEventId?: string) {
  const url = lastEventId
    ? `${bridgeUrl}/events?client_id=${clientId}&last_event_id=${lastEventId}`
    : `${bridgeUrl}/events?client_id=${clientId}`;

  return new EventSource(url);
}

Refer to the bridge API documentation for more details.

Handling TON Connect links for new connections

When a user opens a connection link in your browser wallet, this flow begins:

// This code runs when a URL like this is opened:
// https://wallet.[custodian].com/ton-connect?v=2&id=<client_id>&r=<connect_request>&ret=<return_strategy>
// Parameters in the URL:
// - v: Protocol version (2)
// - id: The dApp's client ID (hex-encoded public key of the dApp's session)
// - r: URL-encoded connect request object
// - ret: Return strategy for the dApp (may be ignored for custodian)

import { ConnectRequest, ConnectEventSuccess, SessionCrypto, KeyPair, ConnectManifest, TonAddressItem, TonProofItem, CHAIN, Base64 } from '@tonconnect/protocol';

window.addEventListener('load', async () => {
  if (window.location.pathname === '/ton-connect') {
    try {
      // 1. Parse the connection parameters from the URL

      const requestEncoded: string | null = searchParams.get('r');

      if (!version || !dAppClientId || !requestEncoded) {
        console.error('Invalid TON Connect URL: missing required parameters');
        return;
      }

      // Decode and parse the request
      const request: ConnectRequest = JSON.parse(decodeURIComponent(requestEncoded));

      // Check if the ton_addr is requested in the connection request, if not, throw an error
      const tonAddrItemRequest: TonAddressItem | null = request.items.find(p => p.name === 'ton_addr') ?? null;

      if (!manifest) {
        console.error("Failed to load app manifest");
        return;
      }

      const userApproved = await confirm(`Allow ${request.manifestUrl} to connect to your wallet?`);
      if (!userApproved) {
        return; // User rejected the connection
      }

      // 3. Create a new session for this connection, this generates a keypair for the session internally
      const sessionCrypto = new SessionCrypto();

      // 4. Get the user's wallet data from custodian API

      const walletStateInit = 'te6cckEBBAEA...PsAlxCarA=='; // Replace with actual wallet's state init from custodian API

      // 5. Create the connect event
      const connectEvent: ConnectEventSuccess = {
        event: 'connect',
        id: 0, // The id field is 0 for connect events

Listening for messages from connected dApps

After establishing connections, you need to listen for messages from connected dApps:

// This function sets up listeners for all active sessions
// Note: this is a simplified example, in a real wallet there can be multiple sessions per one connection
function setupAllSessionListeners() {
  // Get all active sessions
  for (let i = 0; i < localStorage.length; i++) {
    const key = localStorage.key(i);
    if (key && key.startsWith('tonconnect_session_')) {
      const sessionId = key.replace('tonconnect_session_', '');
      const sessionData = JSON.parse(localStorage.getItem(key));

      setupDAppMessageListener(sessionId, sessionData);
    }
  }
}

// Set up a listener for messages from a specific dApp

  }

  // Delete the session
  localStorage.removeItem(`tonconnect_session_${sessionId}`);
}

Refer to the DisconnectEvent documentation for more details.

TON Connect signing

The signing process is a critical component when integrating TON Connect with custodians. Two key cryptographic operations are required: Transaction signing and TON Proof signing.

Transaction signing

For transaction signing implementation, you can refer to the @ton/ton library where wallet integrations are implemented. Please note that this serves as a reference implementation to understand how to achieve transaction signing:

This library provides examples and utilities for TON blockchain operations, but custodians will need to adapt these patterns to work with their specific signing infrastructure and APIs.

TON Proof implementation

For implementing the necessary functionality, two key resources are available:

TON Proof specification

This document provides the complete specification for address proof signatures
Describes the required format and cryptographic requirements

TON Proof verification example

This example demonstrates verification of ton_proof (not signing)
Useful for understanding the proof structure and validation logic

Reference implementations

For practical examples of TON Connect signing implementations, you can review these wallet integrations:

These implementations demonstrate how different wallets handle TON Connect signing operations and can serve as reference points for custodian implementations.
