The onSwapModalStateChange event fires whenever the in-flow swap details modal opens or closes. This is the modal shown over the active swap flow, not the Widget’s main card or wallet-connect dialog.

<LayerswapWidget
  config={widgetConfig}
  callbacks={{
    onSwapModalStateChange: (open) => {
      console.log("Modal state:", open ? "open" : "closed")
    },
  }}
/>
