useBuyNow

Hook for buying a listing on a Marketplace smart contract.

If the listing is in a currency that is not native to the chain (e.g. not Ether on Ethereum), the hook will prompt the user to approve the marketplace contract to spend the currency on their behalf before performing the buy.

import { useBuyNow } from "@thirdweb-dev/react";

Usage

Provide your marketplace contract as the argument.

import { useBuyNow, useContract, Web3Button } from "@thirdweb-dev/react";
import { ListingType } from "@thirdweb-dev/sdk";

// Your smart contract address
const contractAddress = "{{contract_address}}";

function App() {
  const { contract } = useContract(contractAddress, "marketplace");
  const { mutateAsync: buyNow, isLoading, error } = useBuyNow(contract);

  return (
    <Web3Button
      contractAddress={contractAddress}
      action={() =>
        buyNow({
          id: "{{listing_id}}", // ID of the listing to buy
          type: ListingType.Direct, // Direct (0) or Auction (1)
          buyAmount: "{{buy_amount}}", // Amount to buy
          buyForWallet: "{{wallet_address}}", // Wallet to buy for, defaults to current wallet
        })
      }
    >
      Buy Now
    </Web3Button>
  );
