What it does
STON.fi combines TON liquidity pools with Omniston swap aggregation across TON, TRON and EVM networks. Its app separates ordinary swaps from cross-chain routes. Wallets and applications can integrate the same quote and settlement tools through APIs and developer libraries.
A larger fee reservation is not necessarily the final network charge. STON.fi reserves extra native gas tokens for a TON transaction and returns the unused amount after execution. Keep enough for that reservation, even if the asset being exchanged is a stablecoin.
In Swap, choose You pay and You get, then enter an amount on either side. The other field recalculates. Inspect the effective rate, minimum receipt, slippage and reserved network cost before Confirm swap and wallet approval. The resulting explorer link lets you check the transaction. Omniston routes the exchange through available liquidity.
For a supported cross-chain route, open Cross-chain, choose the paying and receiving networks and tokens, then review the quoted result. A TON-to-EVM route needs compatible wallets on both sides. Sign with the wallet on the sending chain and follow settlement until the tokens appear on the receiving chain. An initial token approval may also be needed.
The default TON pool trading fee is 0.3%, but pools are configurable within a 0% to 1% range. The pool page shows its current rate; this is separate from network costs. Cross-chain quotes have their own route-specific costs.
The interface terms require the local age of majority and exclude sanctioned persons and jurisdictions where use is prohibited. Liquidity pools and farming have separate position mechanics from a token swap.
