STON.fi Debuts Cross-Chain Swaps, Bridging TON to TRON and the $160B EVM Stablecoin Economy

STON.fi, the leading decentralized exchange on The Open Network (TON), today announced the launch of its cross-chain swap functionality, marking a pivotal technical integration that connects the TON ecosystem directly to the TRON network and the broader Ethereum Virtual Machine (EVM) stablecoin economy. The new infrastructure enables frictionless asset transfers between TON and major EVM-compatible chains without relying on traditional wrapped tokens or third-party bridges, which have historically been vectors for security exploits. By leveraging an advanced cross-chain messaging protocol, STON.fi’s feature allows users to swap native TON assets for stablecoins like USDT and USDC directly, tapping into the liquidity pools of TRON and leading EVM chains. This development is widely seen as a progressive step for TON, potentially accelerating its adoption among DeFi users seeking lower-fee access to the multi-chain stablecoin ecosystem.

STON.fi, the leading AMM protocol on The Open Network (TON), today announcedin 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,”“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.

STON.fi is a cross-chain decentralized application for token swaps across TON, TRON, and major EVM-compatible blockchains. Originally established as the leading AMM protocol and one of the most widely used DeFi applications on The Open Network (TON), STON.fi helps users swap assets, access DeFi opportunities, and move value across blockchains through a simple cross-chain experience. Its cross-chain capabilities are powered by Omniston, the execution layer developed by STON.fi to support reliable and predictable swaps across multiple networks. Backed by leading investors including CoinFund, Delphi Ventures, The Open Platform, Karatage, TON Ventures, and others, STON.fi is building the infrastructure that connects users, liquidity, and applications across the onchain economy.
