STON.fi, one of the leading AMM protocols on The Open Network ($TON), announced this $TON-native representations of Bitcoin ($BTC) and Ethereum ($ETH) are now available within the ecosystem in a completely non-custodial DeFi format.

$BTC And $ETH are represented on $TON issued as packaged assets $TON-native format, each fully backed 1:1 by the underlying tokens and managed via smart contracts. Ethereum is available as a packaged version $ETH (WETH), while Bitcoin can be accessed through cbBTC, a Bitcoin-backed token issued by Coinbase and fully backed by $BTC on a one-on-one basis. This structure allows both assets to be used in decentralized applications within $TON ecosystem without direct interaction with their own blockchains.
Through STON.fi, users can stake WETH and cbBTC anywhere $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 time. $TON-native token, which drives liquidity throughout the ecosystem. Omniston integrated applications gain instant access to WETH and cbBTC liquidity, enabling swaps between hundreds $TON-based dApps without additional integrations and expanding the reach of available DeFi strategies within the ecosystem.
“To take $BTC And $ETH inside $TON DeFi is about expanding real-world utility, not just asset coverage,” said Slavik Baranov, CEO of STON.fi Dev. “This launch allows users to actively use Bitcoin and Ethereum within $TON ecosystem instead of passively holding them. By making these assets usable in $TON-native DeFi, we strengthen the overall depth of the ecosystem.”
If $TON continues to evolve as a blockchain tightly integrated with Telegram – a messenger used by hundreds of millions of people every day – accessing key crypto assets directly within Telegram native and $TON-based applications have become a natural part of the ecosystem’s evolution. Bitcoin and Ethereum are at the core of the global crypto economy, and their availability is here to stay $TON gives users direct access to these assets within the apps they already use, without leaving the ecosystem, through a decentralized and permissionless infrastructure.
