P2P escrow · TON blockchain · Telegram Mini App

Deal with strangers.
Skip the leap of faith.

Vantox locks the buyer's payment and the seller's file in an on-chain vault, then releases both at once when the deal's conditions are met. The exchange is enforced by code — not by trusting the person on the other side.

The protocol

One deal, six checkpoints

From first click to release, every phase is controlled by the V.S.E. Protocol. Neither side can skip a step — and neither side has to trust the other.

The seller creates the deal

Price and description, done in seconds inside Telegram. The seller shares a deal link — or Vantox detects the negotiation directly in a Telegram group.

The buyer pays into the vault

USDT or GRAM, locked on the TON blockchain. The seller can see the funds are real — but can't touch them. Neither can we.

The seller uploads the file

Encrypted with AES-256 before it leaves the seller's device. Not even the Vantox team can open what's inside the vault.

Automatic threat scan

Every file is checked against the VirusTotal threat database. If something looks suspicious, the buyer sees a clear warning before deciding anything.

The buyer verifies timed window

The buyer confirms everything checks out. If they simply never respond, the deal doesn't hang forever — after the time window, release proceeds automatically.

Simultaneous release

Funds go to the seller, the file goes to the buyer — at the same moment, by protocol rule. Every completed deal generates a PDF receipt automatically.

Something looks wrong?

Either side can flag a problem at any point before the deal completes. A flagged deal pauses the automatic release so it can be reviewed manually — you're never left to argue it out alone.

Two ways to deal

Sell for crypto, or swap file for file

Sale

A digital asset in exchange for USDT or GRAM. Payment waits in the vault; the file is encrypted, scanned and held until both sides have met the deal's conditions. Then both are released at once.

Up to $150 → $1 flat fee Above $150 → 1.5% Paid by the buyer — the seller receives the full agreed price.

Swap

File for file, no money involved. Each side deposits its file into the vault; the same encryption and scanning apply to both, and the two are released simultaneously — an even trade, enforced by code.

Any swap → $1.50 flat fee Split between the parties, or covered by one side — whatever they agree. Same vault, same protection — for both files.

Native to Telegram

Where the deal already happens

Most P2P deals for digital goods are negotiated in Telegram chats — and then break down at "okay, who goes first?". Vantox answers that question without anyone leaving the app.

  • Nothing to install. The Mini App opens inside Telegram — no downloads, no browser wallets, no copying addresses by hand.
  • Deal detection in groups. When two people negotiate in a Telegram group, Vantox can pick up the deal right there.
  • A PDF receipt for every deal. Once a deal completes, both sides get an automatic receipt with the details — useful for your records.
  • AI support, 24/7. @VantoxSupportBot is live around the clock, already answering.
Security

Verify, don't trust

The full picture — threat model, encryption, scan policy and dispute handling — lives on the security page. The short version:

An on-chain vault, not a middleman

Funds are held by the protocol on TON. Nobody at Vantox decides when to release them — code does, when conditions are met.

Encrypted before upload

Files are AES-256 encrypted on your device, before they reach our servers. Only the authorized recipient can decrypt them.

A scan that warns you

Files are checked against VirusTotal before delivery. If something is flagged, you see it clearly — and the choice stays yours.

What we don't claim

No scan catches everything, and we don't inspect the legitimacy or quality of what's being sold. The scan informs — it never blocks a download, and the decision to download is always yours. Vantox protects the exchange: payment and delivery happen together, fairly, or not at all.

Fees

Flat, public, no surprises

Sale — up to $150 $1 flat
Sale — above $150 1.5%
Swap — file for file $1.50 flat
On sales, the buyer always pays the fee — the seller receives the full agreed price. On swaps, the $1.50 fee can be split between the parties or paid entirely by one side — whatever the two agree.
