Decentralized exchange protocol STON.fi, the leading automated market maker on The Open Network (TON), has officially launched cross-chain swap functionality within its app. The new feature allows users to move stablecoins directly between TON and eight other networks: TRON, Ethereum, Base, BNB Chain, Polygon, Avalanche, Arbitrum, and Robinhood Chain.
The integration bridges TON to the broader stablecoin economy, which has a combined market cap exceeding $300 billion, according to the announcement. Users can now shift capital from stablecoin markets on TRON or EVM-compatible chains into TON-native assets, DeFi protocols, and Telegram-native applications without relying on centralized exchanges, traditional bridges, or wrapped tokens.
Under the hood, swaps are powered by Omniston, an execution layer developed by STON.fi. Omniston coordinates the entire process—from pricing to settlement—using Hashed Timelock Contracts (HTLCs). These smart-contract escrows on both source and destination chains ensure an atomic swap: either both legs complete successfully, or the transaction fails and funds are returned. STON.fi claims most swaps finalize in 15–40 seconds.
“People don’t think in terms of blockchains — they think in terms of what they want to do,” said Slavik Baranov, CEO of STON.fi Dev. “Our goal is to make moving between ecosystems feel as simple as swapping within one network. Omniston handles the complexity so users can focus on the outcome, not the infrastructure.”
The move positions STON.fi beyond a single-chain DeFi protocol, evolving toward a product built around user intent. By removing infrastructure management from the end-user experience, STON.fi aims to make cross-chain value transfer as seamless as a simple token swap. The launch is expected to deepen liquidity and expand the utility of the TON ecosystem, while giving TRON and EVM users easier access to TON-based applications and Telegram’s vast user base.
