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.

[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.

An NFT Marketplace where you can list NFTs for direct sale or for auction. Users can come and bid on your listings or buy your NFTs, similar to OpenSea.

An open Marketplace where users can mint their own NFTs and list them or buy NFTs from others.

Users can access the application via web-browser, and must have the Metamask wallet installed. The interface, built with Next.js, relies on the ethers.js library to communicate with the smart contracts through Metamask. This means that the data reflected on the front-end application is fetched from the Polygon blockchain. Each action performed by the user (mint an NFT, sell NFT, buy NFT...) creates a transaction on Polygon, which will require Metamask confirmation and a small fee, and this transaction will permanently modify the state of the NFTMarketplace smart contracts. On top of it, user's NFT Metadata will be uploaded to the IPFS, generating a hash which will be permanently recorded on the blockchain to prove ownership.
