The purpose of this guide is to teach various entry-level concepts for developing with the Polkadot SDK in a hands-on manner.

This guide will walk you through the steps of creating an NFT Marketplace dedicated to collectible digital pets

NFT marketplace by Unique Network.
This tutorial shows the steps that need to be performed to carry out an install of the marketplace on a computer in a local environment or in a virtual machine with Ubuntu OS. The process of installing it in a production environment is identical, with the caveat that your IT administrator will need to setup the supporting infrastructure (such as a globally accessible domain name, hosting, firewall, nginx, and SSL certificates) so that the server that hosts the marketplace can be accessed by the users on the Internet.

A full stack demo NFT marketplace based on aptos devnet. Aiming for clean and cocise code that is easy to understand and also make some automations to speed up full stack development.

NFT Marketplace Frontend

This application shows the basic functionality of NFTs on the Proton chain through the use of the Proton Web SDK.

This is built off of atomicassets NFT framework.

Script for creating your own NFT trading platform

Download Script NFT Marketplace with Support for Fungible Tokens

A rudimentary NodeJS script that scrapes Solana transactions to idenitfy NFT purchases on marketplaces.

code that can be used to run your own marketplace sales tracker for Solana NFTs. It is based on the concept of automatically crediting royalties to creators and using these transactions to identify sales. This ensures that the code is marketplace agnostic, meaning as long as royalties are credited correctly to the NFT creator, the transaction can be identified and analyzed for the required values.

The codebase comes with a cron.js file that can be used to run the tracking process at regular intervals - it uses a simple audit-*.json file to track transactions that have already been processed. (Can be replaced with a database if you want to go that route)

NFT Marketplace on the Cardano Blockchain. Powered by Plutus Smart Contracts A simple contract that allows sales of NFTs. The seller (owner of an NFT) constructs the contract with parameters unique to the sale and locks the NFT there. A buyer can then unlock the NFT by submitting a transaction verifying the several requirements defined in the validator

This project provides sample codes to build a simple NFT marketplace with Amazon Managed Blockchain.

EIP-2981 introduces a “standardized way to obtain royalty payment information for non-fungible tokens (NFTs).” Marketplaces can obtain information about how much royalty to send to whom by calling the royaltyInfo() function of the NFT contract.

A simple ERC-721 token (Token.sol) that provides a fixed royalty percentage of 5% to be paid to a single recipient address for each sale of each NFT minted under the contract. (Note that the fixed percentage fee is not a requirement of EIP-2981, and more exotic schemes are possible.)
A marketplace (Marketplace.sol) that allows a user to post offers to buy NFTs generated by contracts. Token holders can accept the buy offer and sell their tokens at the offer price. Or, they can post their own sell offers at a desired price and wait for the user to buy. All transactions are conducted in ETH. Every time a sale occurs, the marketplace contract calls the token contract to receive the amount of royalties owed. This amount is then transferred to the royalty recipients address.

Royalty Payment Middleware Contract (RoyaltiesPayment.sol). EIP-2981 stipulates that royalty payments must be made to a single address. In the case of an NFT with multiple rights holders, this means that the marketplace payment must be further split either off-chain or through another contract. The contract in this repository allows for multiple rights holders. Every time a payment is made to the contract, the amount is split equally between all registered rights holders. They then have the option to withdraw all or part of their balance from the contract.

Software NFT Marketplace on the Ethereum blockchain. Made in React/Next JS, Solidity and Typescript.

MetaVerse NFT Marketplace in Harry Potter themed 3D style for the Triwizard Tournament.

Mints anything you've created with smart contracts written in Solidity. Presents the created NFT back to the client. Communicates with the Ethereum server via NIFs written in Rust in the API.

Backend-Stack
[Elixir] - Main Roof API
[Rust] - Native functions that interact with the Eth server
[Solidity] - Smart contracts that allow the uploaded item to become an NFT.
[MongoDb] - Metadata for each minted token is stored in mongo.
[Ganache] - Eth server
[Truffle] - Smart contract migrations
[IPFS] - Minted data is stored in ipfs.

OpenOrdex - Open Ordinals Decentralized Exchange
OpenOrdex is an open source zero-fee trustless Bitcoin NFT marketplace based on partially signed bitcoin transactions

How it works
The seller creates a partially signed bitcoin transaction (PSBT) specifying the price of the ordinal.
The buyer can then sign the PSBT and broadcast it to the network.
