STON.fi Crosses the Chains, Lets Stablecoins Hop TON-to-TRON Without the Bridge Burn 🔗

STON.fi, the leading automated market maker on The Open Network, launched cross-chain swaps on July 21, 2026, giving users a self-custodial route to move stablecoins between TON, TRON, Ethereum, Base, BNB Chain, Polygon, Avalanche, Arbitrum, and Robinhood Chain through a single interface. The feature connects TON to major stablecoin ecosystems that together account for more than $300 billion in total market capitalization, with TRON and Ethereum ranked as the two largest stablecoin networks.

The cross-chain swap flow is coordinated by Omniston, STON.fi's execution layer, which links source and destination chains without relying on centralized exchanges, traditional bridges, or wrapped assets. When a swap is confirmed, Omniston matches the order with independent liquidity providers, known as resolvers, that supply the asset on the destination chain. Settlement is handled through linked Hashed Timelock Contracts on both chains using the same cryptographic condition, so both sides complete together or the transaction does not complete at all. Most swaps are reported to settle in 15 to 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."

Before confirming, users see the asset and amount they are expected to receive on the destination chain. If the swap cannot be completed, funds are returned rather than left stuck or partially executed. The product is positioned to give TON users access to liquidity across TRON and EVM networks while giving TRON and EVM users a direct path into TON-native assets, wallets, DeFi protocols, and Telegram-native applications.

With cross-chain swaps now live, STON.fi has expanded beyond a chain-specific DeFi protocol into a product built around user intent, aiming to make multi-chain stablecoin movement predictable from pricing through settlement.
