/**
 * Hook to manage the Swap modal that allows users to swap tokens in their wallet to a target currency.
 *
 * This hook provides methods to open and close the swap modal, and access its current settings.
 * The Swap modal allows users to select tokens from their wallet to swap to a specified target token,
 * with the option to execute additional transactions after the swap completes.
 *
 * @see {@link https://docs.sequence.xyz/sdk/web/checkout-sdk/hooks/useSwapModal} for more detailed documentation.

 * @returns An object containing functions to control the Swap modal and its state {@link UseSwapModalReturnType}

 * @example
 * ```tsx
 * import { useSwapModal } from '@0xsequence/checkout'
 * import { encodeFunctionData, parseAbi } from 'viem'
 *
 * const YourComponent = () => {
 *   const { openSwapModal } = useSwapModal()
