"What's needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party." — Satoshi Nakamoto

This sentence changed everything.

It's where it all started. The idea that kicked off Bitcoin. Roman Nguyen, CTO of RSquad, opened his talk at The Gateway — the loudest, most crowded TON conference of the year.

Not just as a tribute — but as a foundation for something new.

Inspired by Bitcoin’s original vision. Built for TON.
TON Teleport BTC lets you move BTC to TON without intermediaries.
No bridges. No custodians. Just smart contracts and math.

Let’s break down how it works, why it matters, and what makes it different from everything that came before.

Peg-in: Getting BTC to TON

From a user perspective, it’s simple: Send BTC. Wait. Get tgBTC on TON.

At first glance, it looks like a classic bridge. But the key difference? A little bit of magic inside — a light client. A set of smart contracts living inside TON that synchronizes Bitcoin state. Basically, Bitcoin block storage inside TON.

Anyone can send Bitcoin blocks to this light client. No need to trust intermediaries — the light client checks everything itself. If someone tries to send invalid data, the light client simply rejects it. No way to cheat the system.

Once the block is verified, you send your Bitcoin transaction directly to the Teleport smart contracts. Teleport checks if your transaction is included in a confirmed block. If yes, it processes your transaction piece by piece — pulling all needed data like sender, receiver, and so on. If everything matches, you get tgBTC on TON.

This is what makes TON Teleport BTC different from classic bridges that rely on some external observer saying, "Hey, Bitcoin moved, please mint tokens." Here, it's all verified directly from the Bitcoin blockchain.

Peg-out: Getting BTC back

Burn tgBTC on TON. Specify the recipient's Bitcoin address. Wait for confirmations. Receive BTC back.

Sounds simple. But here’s the catch: Bitcoin doesn’t support light clients like TON does.

So how do you unlock BTC? Enter TON validators.

Validators don’t verify Bitcoin transactions directly. Instead, they wait for a confirmed burn event on TON. Once that's verified, they sign the Bitcoin transaction prepared by the smart contracts and send it back to Teleport.

Validators stay decentralized. No one controls the funds alone.

Cryptography powering TON Teleport BTC

ON Teleport BTC uses modern cryptographic tools like DKG (Distributed Key Generation) and FROST (Flexible Round-Optimized Schnorr Threshold Signatures).

• DKG allows validators to generate a key together without anyone holding the full key.
• FROST helps to aggregate their signatures efficiently, reducing Bitcoin transaction costs.

Validators rotate. Keys rotate. The system stays secure.

On trust and decentralization

Some people might say:

"Wait, validators sign the transaction — isn’t that custodial?"

Well, think about Uniswap on Ethereum. Is it trustless? Technically, yes — smart contracts handle everything. But if Ethereum validators stopped processing your transactions, what then?

Every blockchain relies on its consensus. Bitcoin relies on miners. Ethereum on validators. TON on its own validators.

TON Teleport BTC doesn't introduce new trust layers. It just relies on TON's existing consensus and smart contracts.
