Swap
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 (i.e. USDT on Ethereum -> 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.
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.
