STON.fi, the leading AMM protocol on The Open Network (TON), announced that TON-native representations of Bitcoin (BTC) and Ethereum (ETH) are now available within the ecosystem in a fully non-custodial DeFi format. The integration gives TON users direct access to the two largest crypto assets, including the ability to swap them and provide liquidity, while maintaining full control over their funds.

BTC and ETH are represented on TON as wrapped assets issued in TON-native format, each fully backed 1:1 by the underlying tokens and managed through smart contracts. Ethereum is available as wrapped ETH (WETH), while Bitcoin is accessible via cbBTC, a Bitcoin-backed token issued by Coinbase and fully collateralized with BTC on a one-to-one basis. This structure allows both assets to be used across decentralized applications within TON ecosystem without interacting directly with their native blockchains.

Through STON.fi, users can deploy WETH and cbBTC across TON DeFi, including swapping and providing liquidity via WETH/USDt and cbBTC/USDt pools. At the same time, Omniston, STON.fi’s liquidity aggregation protocol, enables swaps to WETH and cbBTC from any TON-native token, routing liquidity across the ecosystem. Applications integrated with Omniston instantly gain access to WETH and cbBTC liquidity, enabling swaps across hundreds of TON-based dApps without additional integrations and expanding the range of available DeFi strategies within the ecosystem.

“Bringing BTC and ETH into TON DeFi is about expanding real utility, not just asset coverage,” said Slavik Baranov, CEO of STON.fi Dev. “This launch enables users to actively use Bitcoin and Ethereum inside TON ecosystem rather than holding them passively. By making these assets usable in TON-native DeFi, we’re strengthening the overall depth of the ecosystem.”

As TON continues to develop as a blockchain closely integrated with Telegram — a messenger used daily by hundreds of millions of people — access to major crypto assets directly within Telegram-native and TON-based applications has become a natural part of the ecosystem’s evolution. Bitcoin and Ethereum sit at the core of the global crypto economy, and their availability on TON allows users to access these assets directly within the apps they already use, without leaving the ecosystem, through decentralized and permissionless infrastructure.
