STON.fi Launches Cross-Chain Swaps, Connecting TON with TRON and EVM Stablecoin Economic Ecosystem

STON.fi — the leading AMM protocol on The Open Network (TON) — today announced the official launch of its cross-chain swap feature, providing users with a unified self-custodial interface for directly transferring stablecoins between TON, TRON, Ethereum, Base, BNB Chain, Polygon, Avalanche, Arbitrum, and Robinhood Chain.

This launch connects TON with major liquidity and application ecosystems. Users can freely move capital between stablecoin markets, TON-native assets, DeFi protocols, and Telegram-native applications without relying on centralized exchanges, cross-chain bridges, or wrapped assets.

Stablecoins have become one of the most important sectors in the crypto market, with a total market cap exceeding $300 billion, with TRON and Ethereum being the two largest stablecoin networks. Through cross-chain swapping, STON.fi establishes two-way connectivity between TON and the mainstream stablecoin ecosystem: TON users can access multi-network liquidity, while TRON and EVM users can more directly reach TON-native assets, wallets, DeFi protocols, and Telegram-native applications — all within a unified self-custodial experience, without managing cross-chain bridges, wrapped assets, routing decisions, or settlement uncertainties.

Omniston is STON.fi's proprietary execution layer, responsible for coordinating the entire swap process between the source and target chains. It is more than just a routing or liquidity aggregation system; it aims to ensure predictable completion of cross-chain stablecoin flows from pricing to settlement.

Slavik Baranov, CEO of STON.fi Dev, stated: "Users don't think in terms of blockchains — they think about what they want to do. Our goal is to make cross-ecosystem transfers as simple as swapping within a single network. Omniston handles all the complexity, letting users focus on the outcome, not the underlying infrastructure."

For users, the core advantages are speed and predictability. Most swaps complete within 15 to 40 seconds, allowing users to exchange assets across any supported chain without the long wait times typical of cross-chain transactions. Once a swap is confirmed, Omniston matches the order with an independent liquidity provider (a resolver), who supplies the asset on the destination chain. The transaction executes via associated Hash Time-Locked Contracts (HTLCs) — smart contract escrow mechanisms using the same cryptographic conditions on both chains — ensuring that both legs of the swap complete simultaneously, or the entire transaction is nullified. Before confirmation, users can see the expected asset and amount. If the swap cannot be completed, funds are returned, with no risk of stuck, partially executed, or ambiguous states.

With the launch of cross-chain swapping, STON.fi is evolving from a single-chain DeFi protocol into a product built around user intent. As stablecoin liquidity, consumer applications, and DeFi markets expand across various networks, users need a more seamless way to transfer value without giving up self-custody or managing the infrastructure behind each transaction. For both TON and the broader crypto market, this launch introduces a more practical access layer between major liquidity networks, application ecosystems, and the wider on-chain economy.
