Requirements & limits

The repository is public and identifies its license as GPL-3.0. The README documents installation through npm or Yarn.

  • The documented actions are NFT listings and offers through Metaplex Auction House.
  • The README's React example expects an Auction House, NFT, wallet and connection.
  • The SDK supplies marketplace transaction actions, not a complete marketplace application.
  • The repository recommends TypeScript and identifies GPL-3.0 as its license.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add listing and offer actions to a React page

Use the README's React example to compose and send an NFT listing or offer transaction.

Before you start

  • Install @holaplex/marketplace-js-sdk with npm or Yarn.
  • A React environment using Solana wallet-adapter hooks.
  • An Auction House, NFT, wallet and Solana connection supplied to the page.

Steps

  1. Import initMarketplaceSDK, AuctionHouse and Nft from the package, and useConnection and useWallet from @solana/wallet-adapter-react.

  2. Initialize the SDK with the connection and wallet.

  3. For a listing, add sdk.listings(auctionHouse).post({ amount, nft }) to an SDK transaction and send it.

  4. For an offer, add sdk.offers(auctionHouse).make({ amount, nft }) to an SDK transaction and send it.

Expected outcome

The page can submit listing or offer actions through Metaplex Auction House.

Guide limitations

  • The example does not establish that the SDK deploys or runs a complete marketplace.
  • Application-specific transaction handling remains necessary.
