The Chainwire announcement says most swaps complete in 15–40 seconds through Omniston, linking TON with stablecoin liquidity on networks including Ethereum, Base, BNB Chain and Polygon.
STON.fi said it has launched cross-chain swaps in its app, letting users move stablecoins through a self-custodial interface across TON, TRON, Ethereum, Base, BNB Chain, Polygon, Avalanche, Arbitrum and Robinhood Chain. The company said the rollout is meant to connect TON with major liquidity and application ecosystems, allowing users to move capital between stablecoin markets, TON-native assets, DeFi (blockchain-based financial applications) protocols and Telegram-native applications without centralized exchanges, bridges or wrapped assets. STON.fi said its Omniston execution layer coordinates the swap process between source and destination chains, with most transactions completing in 15–40 seconds. The system uses resolvers (independent liquidity providers) and linked Hashed Timelock Contracts, or HTLCs (smart-contract escrows with timed conditions), so both sides of a trade settle together or not at all. STON.fi framed the launch as a step beyond a chain-specific DeFi product toward a user-intent model as stablecoin liquidity and onchain applications spread across multiple networks.
