TON Teleport Project

TL;DR: TON Teleport Project (TTP) is a cross‑chain bridge that lets users move $BTC between the Bitcoin blockchain and TON using lock‑and‑mint and burn‑and‑release mechanisms. The bridge operates without a centralized custodian, aiming for transparent and decentralized token swaps.

Overview#

TON Teleport Project (TTP) is a tool on The Open Network that enables secure cryptocurrency exchanges between TON and other blockchains, most notably Bitcoin. It is positioned as a network bridge that removes the need for centralized intermediaries.

The bridge’s primary goals are:

Enhanced connectivity between blockchains
Transparent, on‑chain transaction auditability
Decentralized control with no external authority
Integration of Web3 services into a unified network

How TTP Transfers $BTC#

Peg‑in (Bitcoin → TON)

The user sends $BTC to a designated Bitcoin address.
After the Bitcoin transaction is confirmed and the $BTC is locked, an equivalent amount of $BTC tokens is minted on the TON network.
These TON‑$BTC tokens can be used in TON dApps, DEXs, or later exchanged back to Bitcoin.

Peg‑out (TON → Bitcoin)

The user burns the TON‑$BTC tokens.
The bridge releases the original $BTC on the Bitcoin blockchain to the user’s address.

Both processes rely on smart contracts that lock assets on the source chain and mint or release equivalents on the destination chain.

Transaction Types#

Lock‑and‑Mint

Tokens are locked on the source blockchain and newly minted on the receiving blockchain. TTP acts as the intermediary that holds the locked assets and issues the corresponding tokens.

Burn‑and‑Release

An extension of Lock‑and‑Mint where minted tokens are burned on the destination chain, triggering the release of the original assets on the source chain.

Burn‑and‑Mint

Tokens are burned on one receiving blockchain and minted on another, allowing cross‑bridge transfers without affecting assets locked on the original source chain. For example, $BTC on Ethereum can be burned and re‑issued on TON.

Alternative TON Bridges#

TONBANKCARD – a TON bridge allowing up to 100 TON per transaction with minimal fees.
Rubic – a cross‑chain aggregator that provides SDKs for building DEXs and NFT bridges.
Utyabswap – a simplified service for transferring tokens from various blockchains to TON.

A comprehensive list of TON bridges is available on the TON App.

Security Considerations#

While network bridges like TTP solve interoperability challenges, they inherit security risks from the connected blockchains and the bridge’s smart contracts. Any vulnerability in a source or destination chain, or in the bridge’s contract code, can compromise the assets being transferred.
