Metaplex Standard

The foundational on-chain program that defines the NFT standard on Solana. It attaches rich, mutable metadata—like name, symbol, URI, and creator royalties—to SPL tokens, transforming them into non-fungible assets. This program enforces creator royalties and provides the data schema for all wallets and marketplaces to display NFTs uniformly.

A configurable, secure minting program for launching large-scale NFT collections with fixed rules. It handles:

• Fair launches: Configurable start times and mint prices.
• Reveal mechanics: Hidden NFTs that are revealed post-mint.
• Guard rails: Bot protection and mint limits. It is the standard tool for generative art and profile picture (PFP) collection launches, ensuring a trustless and predictable minting process.

A decentralized, permissionless marketplace protocol. It allows anyone to run their own NFT marketplace by providing core auction logic, including:

• Listings and Bids: Direct peer-to-peer trading.
• Escrow & Settlement: Secure handling of funds and assets.
• Fee Structure: Configurable marketplace and creator fees. This program decentralizes marketplace infrastructure, enabling everything from large platforms to DAO treasuries to conduct trustless sales.

A high-performance GraphQL API that provides a unified interface for querying digital assets on Solana. It abstracts away blockchain complexity, allowing developers to easily fetch:

• NFT details and metadata.
• Ownership and provenance history.
• Compressed NFT data. This API is the primary data layer for wallets, explorers, and applications building on Metaplex, significantly simplifying data retrieval.

An advanced NFT standard that introduces delegated authority and rule-based interactions. Key features include:

• Delegate Roles: Assign specific permissions (e.g., sale, transfer) to other wallets.
• Locking & Unlocking: Enforce rules for asset utility (e.g., staking, gaming).
• Enhanced Security: Reduces phishing risk by limiting signer requirements. pNFTs enable complex use cases like rentable assets, lending protocols, and on-chain gated experiences.

A program for minting compressed NFTs that store metadata and proof of ownership on-chain but leverage Solana's state compression to reduce minting costs by over 99%. This enables:

• Mass-scale minting: Distributing millions of NFTs affordably.
• Low-cost utility: Ideal for event tickets, loyalty points, and in-game items.
• Same security: Inherits the full security of the Solana L1. It represents a major innovation in making blockchain utility cost-effective.

The Metaplex Core Standard is the default for most Solana NFT projects. It defines the Metadata Account structure, which stores the NFT's name, image URI, and attributes. This enables marketplaces like Magic Eden and Tensor to display and trade NFTs uniformly.

• Example: A generative art project mints 10,000 unique PFPs, each with traits stored in the attributes array of its metadata.
• Use Case: Artists use tools like Sugar or Candy Machine to deploy collections that are instantly compatible with the entire Solana NFT ecosystem.

Programmable NFTs introduce rules and royalties enforced on-chain via the Token Metadata program. This is a primary use case for the Metaplex Standard's advanced features.

• Example: A game issues pNFTs for in-game items. The creator sets a 10% royalty and transfer restrictions that are checked on every sale or trade.
• Key Mechanism: The Rule Set account dictates authorization logic, allowing for features like time-locked transfers or approved marketplace-only sales.

While known for NFTs, Metaplex also defines standards for fungible tokens with rich metadata, such as Token-2022 extensions. This allows for compliant, feature-rich tokens.

• Example: A project launches a governance token with transfer fees and a metadata URI pointing to a logo and description, all deployed using Metaplex's Token Extensions specifications.
• Use Case: Creating tokens with built-in transfer hooks, confidential transfers, or non-transferable properties for credentials.

State Compression and Compressed NFTs (cNFTs) use the Metaplex Standard's metadata in conjunction with Merkle trees to store NFT data at a fraction of the cost.

• Example: A loyalty program mints 10 million cNFT membership cards. The proof of ownership is stored in a Merkle tree, while the core metadata (image, name) still follows the Metaplex schema.
• Key Benefit: Drastically reduces minting costs (e.g., ~$50 for 1 million cNFTs vs. millions for traditional NFTs), enabling massive-scale applications.

The foundational on-chain program that defines the NFT standard on Solana. It stores metadata (name, symbol, URI) and attaches it to SPL tokens, enabling them to function as non-fungible assets. Key features include:

• Permanent, immutable metadata stored on-chain.
• Creator royalties and verification.
• Mutable/immutable data configurations for the URI.
• Collection management and verification.

A configurable, on-chain program for launching large-scale NFT collections with fair minting mechanics. It is the standard tool for generative art projects (PFP collections) and handles:

• Configurable mint phases (allowlist, public).
• Guarded launches with bot protection.
• Reveal mechanics for hidden NFTs.
• Automated distribution and on-chain tracking of mint progress.

A unified GraphQL API for querying digital assets (NFTs, Fungible Assets, Compressed NFTs) on Solana. It abstracts away the complexity of direct RPC calls and provides a single interface for:

• Fetching assets by owner, collection, or creator.
• Retrieving full metadata and provenance.
• Supporting all Metaplex asset types in one query.
• Indexing assets from multiple sources (legacy, Bubblegum).

A state compression technology that drastically reduces the cost of minting and storing NFTs by storing proof data on-chain and asset data off-chain. Enabled by the Bubblegum program, it allows for:

• Mass minting at ~0.0001 SOL per NFT.
• On-chain ownership and transferability via Merkle trees.
• Scalable applications like loyalty programs and event tickets.
• Full compatibility with wallets and marketplaces via the DAS API.

A decentralized, permissionless marketplace protocol that allows anyone to create their own NFT marketplace. It provides the core trading logic for:

• Listing and bidding on NFTs.
• Configurable fees for creators and platforms.
• Instant sales and English auctions.
• Royalty enforcement for secondary sales. Projects like Magic Eden and Hyperspace are built on this standard.

The primary TypeScript/JavaScript library for developers to interact with Metaplex programs. It provides high-level abstractions and simplifies on-chain operations such as:

• Minting NFTs and managing collections.
• Creating and managing Candy Machines.
• Interacting with Auction House listings and bids.
• Reading and updating metadata. It is the standard tool for building NFT applications on Solana.

The foundational set of on-chain programs that define the NFT standard on Solana. It includes the Token Metadata Program, which stores attributes like name, symbol, and URI for NFTs, and the Token Entangler for creating linked NFT pairs. This core layer establishes the universal data model that all Solana wallets and marketplaces recognize.

A configurable, on-chain program for launching large-scale, fair NFT mints. It automates the minting process with features like:

• Guarded Launches: Enforce start times, mint limits, and allow lists.
• Configurable Sales: Set prices, collection sizes, and reveal mechanics.
• Immutable Rules: Once deployed, mint parameters cannot be altered, ensuring trustlessness. It is the standard tool for curated NFT drops.

A unified GraphQL API for querying digital assets (NFTs and Fungible Tokens) on Solana. It provides a single interface to fetch comprehensive asset data, including:

• Metadata & Properties: All on-chain and off-chain attributes.
• Ownership & Provenance: Current owner and mint history.
• Collection Verification: Proof an NFT belongs to a verified collection. It simplifies development by abstracting complex on-chain data fetching.

A program for creating Compressed NFTs (cNFTs), which store metadata and proof of ownership on-chain but leverage Solana's state compression to reduce minting costs by over 99%. Key traits:

• Cost-Efficient: Mint thousands of NFTs for the cost of a few traditional ones.
• Scalable: Enables massive, on-chain NFT distributions (e.g., loyalty programs).
• Merkle Trees: Uses cryptographic proofs to verify ownership without storing all data in every account.

The central on-chain program that defines the schema and authority model for NFT data on Solana. It governs:

• Metadata Accounts: PDA accounts that store the NFT's URI, name, symbol, and mutable/immutable attributes.
• Update Authorities: The wallets permitted to modify an NFT's metadata.
• Verification: Processes for verifying NFTs as part of a collection or as a creators. It is the definitive source of truth for NFT properties.

A next-generation, modular framework for creating digital assets on Solana, designed to succeed and extend the original Metaplex Core. It introduces:

• Plugins: Modular components for adding functionalities like royalties, permanent delegates, or transfer hooks.
• Asset Types: Native support for both Fungible and Non-Fungible assets within a unified system.
• Enhanced Flexibility: Creators can define custom asset behaviors and data structures, moving beyond a rigid NFT standard.
