# Royalty Registry ## Overview The goal of the Royalty Registry is twofold: * Make it easy for marketplaces to use the appropriate on-chain royalty configurations * Make it possible for contracts that did not originally support on-chain royalties to add them The Royalty Registry was created in collaboration with Coinbase, Foundation, Makersplace, Nifty Gateway, OpenSea, Rarible, SuperRare and Zora. Read more about how the Royalty Registry came about in our original [blog post](https://manifoldxyz.substack.com/p/royaltyregistryxyz). ## Documentation All documentation links can be found at [royaltyregistry.xyz](https://royaltyregistry.xyz) Both the website and smart contracts are open source, and can be located: * [Website GitHub repo](https://github.com/manifoldxyz/royalty-registry-client) * [Smart Contract GitHub repo](https://github.com/manifoldxyz/royalty-registry-solidity) All official deployment addresses for each network can be found at [royaltyregistry.xyz](https://royaltyregistry.xyz) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
