Why should I implement instant swaps into my dApp?

Instant swaps matter because they keep the exchange moment inside the dApp.To build an app that works across multiple chains (EVM, Bitcoin, Tron, Solana, and others), you can integrate ChangeNOW that operates as a dApp exchange layer: the app gets one swap flow while we handle routing, liquidity access, and maintenance across networks.

If your product has its own native token, you can also list it on ChangeNOW to let users swap it into stablecoins and other supported assets inside the app. Users do not have to leave the product to move between assets, and the app can earn commission on each transaction, starting at 0.4%. The integration of seamless in-app crypto swaps is possible through the API or Widget.

Can I customize the UI/UX?

Yes. The Widget is the faster option when you want an embedded swap flow without rebuilding the whole interface. It can be adjusted to match the product more closely: layout, primary and background colors, logo visibility, dark theme, FAQ block, localization, language selector, default tab, default amount, and preset “from” / “to” currencies. The same widget can also be configured for exchange and top-up cases.

At the same time integration by exchange API gives you full control to build a completely custom swap experience tailored to your product.
