On this page you will find howto build your own personal NFT store or even a multi vendor NFT Marketplace.

Ethereum, Binance Smart Chain (BSC), Polygon (MATIC) and any other EVM compatible blockchain with etherscan-like API is supported.

Personal NFT Store

Personal NFT store is an eCommerce store where only you as a site author/owner can create and sell NFT tokens. Other people will not be able to create new NFT tokens or resell purchased NFT tokens on your site.

To build a personal NFT store these plugins are required:

• Cryptocurrency WordPress Plugin for WooCommerce
• NFT WordPress Plugin for WooCommerce

And this one is an optional, but highly recommended:

• WordPress Ethereum Wallet plugin

There is a NFT WordPress Plugin Kit that contains all these three plugins mentioned above with a discount.

This one can be used to accept Ether and/or some ERC20 token like DAI or USDT:

• Ether and ERC20 tokens WooCommerce Payment Gateway

The Configure WordPress Plugins Service can be used to let us configure plugins for you.

Multi Vendor Marketplace

The multi-vendor marketplace option let other people to create new NFT tokens on your store, and resell purchased NFT tokens on your site.

To build a multi-vendor NFT marketplace, these plugins are needed:

• WC Vendors Marketplace Add-On
• WC Vendors Pro
• NFT WordPress Plugin Kit

The Configure WordPress Plugins Service can be used to let us configure plugins for you.

NFT Tokens Minting

An ERC721 smart contract needs to be deployed in a blockchain to mint your tokens with these plugins.

We have a Smart Contract Development Service you can order to let us develop and deploy a contract for you.

These options are required for NFT project:

• Basic NFT Token
• Metadata
• White List/KYC
• Ownable
• Contract Deployment

Look for these options under the NFT Token Options section

You need to choose a blockchain to use for your tokens. Ethereum is very expensive on deployment, minting or sending tx fees. Polygon (MATIC) and Binance Smart Chain (BSC) are also supported. The Polygon (MATIC) blockchain is recommended for negligible tx fees.

Tokens on the Polygon (MATIC) chain can be bridged to the Ethereum later if needed.

Auction

Auction features can be added with any WooCommerce Auction plugin, but if multi vendor is needed, then you need to use:

• WC Vendors WooCommerce Simple Auctions and
• WooCommerce Simple Auctions – WordPress Auctions
• (Optional) WooCommere Simple Auction Buy Bid Credits

The Configure WordPress Plugins Service can be used to let us configure plugins for you.

White List/KYC

After your contract is deployed, the final step is to allow the admin address to mint tokens. This address is generated or configured on a page like: https://example.com/wp-admin/options-general.php?page=cryptocurrency-product-for-woocommerce&tab=default See the Ethereum wallet address setting documentation.

You need to call the grantRole method for the admin address to give it the MINTER role: 0x9f2df0fed2c77648de5860a4cc508cd0818c85b8b8a1ab4ceeef8d981c8956a6

• First argument: 0x9f2df0fed2c77648de5860a4cc508cd0818c85b8b8a1ab4ceeef8d981c8956a6
• Second argument: Your admin address here. See above.

And you need to do it from your NFT token contract owner address. Check it in the owner property of your contract.

See this video guide for details please:

After it will be done, send some ETH/BNB/MATIC to your admin address to pay NFT minting fees.

Note that vendor minting can be configured instead of the admin minting. But in this case you’ll need to call the grantRole method for each new vendor approved. And vendors need to top up their wallets with ETH/BNB/MATIC for minting fees. The admin minting is much more user friendly solution.

There is a way to let buyers compensate the minting tx cost by adding a shipping fee or a token price mark up fee.

Theme Requirements

Any WooCommerce compatible theme should work OK. In the multi vendor case the more precise requirement can be if it supports the WCVendors plugin, but it is optional. In most cases WooCommerce should be just enough.

IPFS storage

Images and video files of your NFTs can be stored on your server, or on IPFS using pinata.cloud or nft.storage service.

IPFS storage is better since it adds more trust to your tokens.

NFT Media Submarining

Any number of downloadable files can be added to an NFT token product. These files will not be uploaded to IPFS. Only hashes will be calculated and added to the attributes section of the NFT meta data JSON file stored in IPFS.

This way only NFT token owner will be able to download such submarined files from your site, and in the same time, NFT token owner can alway verify if files provided are the right ones by calculating it’s hashes and compare it with hashes from the JSON meta data file.

NFT WordPress Plugin vs. opensea

The fundamental difference of the NFT WordPress Plugin Kit with opensea and other similar platforms is that opensea is implemented as a smart contract on a blockchain, and the NFT WordPress Plugin Kit is not. All logic is implemented in a traditional server side PHP code.

Both of these implementations have advantages and disadvantages:

• The opensea advantage is that payment and minting can be done in a single transaction. Buyer pays the tx fee and can be 100% sure that the token will be sent to him after the payment.
• The opensea disadvantage is that since payment and minting transactions are coupled, they can not accept fiat or Bitcoin for example, only ETH for Ethereum based tokens, or MATIC for Polygon based tokens.

For the NFT WordPress Plugin Kit it is vice versa:

• The NFT WordPress Plugin Kit advantage is that payment and minting transactions are decoupled. It allows accepting virtually any fiat or crypto currency as a payment. 
• The NFT WordPress Plugin Kit disadvantage is that since payment and minting transactions are decoupled, the buyer pays only for the payment transaction, and the seller should pay for the minting transaction. And the buyer can not be 100% sure that the token will be sent to him after the payment, since there is no smart contract in between that can guarantee it.

There is a way to let buyers compensate the minting tx cost by adding a shipping fee or a token price mark up fee.

An additional NFT WordPress plugin advantage is that it can be easily integrated in the WordPress/WooCommerce plugins ecosystem, giving the site admin virtually endless toolkit to implement the site’s idea with a very reasonable budget.
