How to Gate Private Telegram Groups with TON Soulbound Tokens (SBTs)

Quick Summary:

• Manual invite links to private event Telegram groups leak within hours, flooding private communities with spammers and unverified guests.
• By gating Telegram groups with Soulbound Tokens (SBTs) on the TON blockchain, community access is permanently tied to verified real-world event attendees.
• ONTON provides an automated bot pipeline that handles token issuance, single-use chat invitation, and automated expulsion upon ticket cancellation.

The Problem with Static Telegram Invite Links

Event organizers and DAO community leads understand the pain of managing exclusive attendee chats:

1. Link Leaks: An attendee shares the "VIP Event Chat" link into a public group, resulting in hundreds of unauthorized lurkers.
2. Admin Burnout: Community managers spend hours manually reviewing wallet screenshots or cross-checking ticket numbers against Telegram usernames.
3. No Exit Mechanism: When an attendee cancels their ticket or is ejected for violating code-of-conduct, organizers have no programmatic way to remove them from all related sub-channels.

Why Soulbound Tokens (SBTs)?

A soulbound-token (SBT) is a non-transferable NFT anchored to a specific wallet. Unlike standard ERC-721 or Jetton tokens that can be purchased on secondary markets or loaned to third parties:

• An SBT cannot be sold or transferred to another address.
• It acts as an irrevocable cryptographic reputation and attendance credential.
• When minted upon ticket purchase, it guarantees that the person in the Telegram group is the exact verified attendee.

1. Zero-Gas Wallet Binding

Using ton-connect, the attendee binds their TON wallet (Tonkeeper, Telegram Wallet, MyTonWallet) inside the ONTON Telegram Mini App during ticket registration.

2. On-Chain SBT Issuance

The smart contract deploys an immutable SBT record containing:

• eventId: Unique identifier of the conference or meetup.
• tier: General Admission, Speaker, VIP, or Sponsor.
• timestamp: Block time of purchase.

3. Telegram Single-Use Join Request

ONTON's bot creates an ephemeral Telegram chat invite link configured with creates_join_request=True. When the user clicks join, the bot verifies the wallet signature and approves the join request in real time.

Step-by-Step Setup for Organizers

1. Add @theontonbot as Admin to your Telegram Group: Grant permissions to invite users via link and ban users.
2. Link Event in Mini App: Open @theontonbot/event and choose "Connect Community Chat".
3. Select Gating Rules:
   • Require General Admission SBT.
   • Require VIP SBT for exclusive breakout topic chats.
4. Publish Event: All registered attendees now receive instantaneous, secure entry.
