Not long ago STONfi launched cross-chain swaps. TON, Ethereum, Base, BNB Chain, Polygon are now connected inside one interface. It looks simple: choose a pair, press swap, get tokens in another network. But behind this simplicity lies a problem rarely discussed: the same tokens have different prices in different networks.

Take USDT. On $GRAM it may have one price, on Ethereum a slightly different one, on Base a third. The difference is usually tiny, but it exists. And when you make a cross-chain swap, it is not enough to just find the best course inside one network. You need to match courses in two different networks at the same time, account for transfer fees, and make sure the transaction goes through at the expected price.

Omniston solves this through RFQ, request for quotes. The protocol does not just look at current prices in pools, it requests specific offers from market makers ready to execute a swap between networks. They set their rates accounting for all risks, and Omniston picks the best one.

But even here there is a catch. While you confirm the swap, the rate may shift. Especially with volatile tokens rather than stablecoins. That is why cross-chain on STONfi currently works mainly with USDT, USDC, and pUSD. These are tokens with minimal divergence between networks, where slippage is predictable.

Over time as liquidity between networks deepens, the price difference will shrink. But for now cross-chain is not magic, it is complex logistics that works because Omniston does not just find a price, it coordinates the entire process from request to finalization.
