STON.fi, the leading AMM protocol on The Open Network (TON), today announced the launch of cross-chain swaps in the STON.fi app, giving users a direct way to move stablecoins between TON, TRON, Ethereum, Base, BNB Chain, Polygon, Avalanche, Arbitrum, and Robinhood Chain through a unified, self-custodial interface. 

The launch connects TON to major liquidity and application ecosystems across crypto. As a result, users can move capital between stablecoin markets, TON-native assets, DeFi protocols, and Telegram-native applications without relying on centralized exchanges, bridges, or wrapped assets.

Stablecoins have become one of crypto’s most important markets, with more than $300 billion in total market capitalization, led by TRON and Ethereum as the two largest stablecoin networks. Through cross-chain swaps, STON.fi connects TON with major stablecoin ecosystems in both directions: TON users gain access to liquidity across networks, while TRON and EVM users get a more direct path into TON-native assets, wallets, DeFi protocols, and Telegram-native applications — all through one self-custodial experience without managing bridges, wrapped assets, routing decisions, or settlement uncertainty.

Omniston, the execution layer developed by STON.fi, coordinates the full swap process between source and destination chains. More than a routing or liquidity aggregation system, it is designed to help cross-chain stablecoin flows complete predictably, from pricing to settlement.

“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.”

For users, the key benefits are speed and predictability. Most swaps complete in 15–40 seconds, allowing users to swap assets between any supported chains without the longer wait times often associated with cross-chain transactions. When a swap is confirmed, Omniston connects the order with independent liquidity providers, known as resolvers, that supply the asset on the destination chain. The transaction is executed through linked Hashed Timelock Contracts (HTLCs) — smart-contract escrows on both chains that use the same cryptographic condition — so both sides of the swap complete together or the transaction does not complete at all. Before confirming, users see the asset and amount they are expected to receive. If the swap cannot be completed, funds are returned instead of being left stuck, partially executed, or unclear.

With cross-chain swaps now live, STON.fi is moving beyond a chain-specific DeFi protocol toward a product built around user intent. As stablecoin liquidity, consumer applications, and DeFi markets spread across networks, users need easier ways to move value without giving up self-custody or managing the infrastructure behind each transaction. For TON and the broader crypto market, the launch introduces a more practical access layer between major liquidity networks, application ecosystems, and the wider onchain economy.
