Watch Swap demo on YouTube.
Phantom supports deeplinking directly to the in-app swapper. Developers can specify which tokens should be prefilled in the buy and sell fields. In addition to swapping tokens on a single chain, the swapper can also be used to bridge stablecoins across chains, such as USDT on Ethereum to USDC on Solana. The swap deeplink can be used at anytime. It does not need to be proceeded by a Connect event, as it does not require a session param.
The swap deeplinks are not intended to be pasted into mobile web browsers. These deeplinks must either be handled by an app or tapped on by an end user.
