True to our mission, OpenSea is continuing to build the most inclusive NFT marketplace with the best selection – now, by onboarding collections on the Solana blockchain. This guide will help you understand what the Metaplex Certified Collection standard (MCC) is for Solana collections, and why it’s important.
Let’s get started!
What is the Metaplex Certified Collection Standard?
The Metaplex Certified Collection standard is the current backbone of the Solana NFT ecosystem. Historically, there hasn’t been a concept of an NFT “collection” on Solana marketplaces. In order to establish this “collection” formatting on OpenSea, we are using the Metaplex Certified Collection standard to replicate a native collection.
This on-chain standard verifies that every NFT is part of a collection by tying together thousands of NFTs.
- For all new Solana projects: Using MCC lends authenticity to your project. It’s a codeless process, and you can kick it off on the Metaplex website.
- For existing Solana projects: You’ll need to use this tool to migrate your existing project to the latest version. Once you’ve migrated, your collection will be listed on OpenSea automatically.
Make sure you fully complete the MCC process to verify your tokens, in order to ensure that all tokens are properly associated with the collection. If it gets interrupted, you can restart the process with your full list of tokens.
