STON.fi Opens TON DeFi to Bitcoin and Ethereum

STON.fi, one of the leading AMM protocols 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.
