Dynamic Updates

All attributes are reactive. Changing them after mount updates the widget: 
const widget = document.querySelector("argyros-swap");

// Switch to Fogo chain
widget.setAttribute("chain", "fogo");

// Point to a different API
widget.setAttribute("base-url", "http://localhost:8080");

// Change RPC endpoint
widget.setAttribute("rpc-url", "https://mainnet.fogo.io");

// Switch theme
widget.setAttribute("theme", "light");
When api-key, chain, or base-url change, the widget re-creates the internal SDK client. When rpc-url changes, subsequent balance queries use the new endpoint.
