Metaplex

metaplex-foundation/skill

This is the official Metaplex skill for building NFTs and tokens on Solana. It covers the full stack: Core for next-gen NFTs, Token Metadata for fungibles and legacy collections, Bubblegum for compressed NFTs at scale, Candy Machine for drops, Genesis for token launches with bonding curves, and Agent Registry for on-chain agent identity. The skill strongly prefers CLI over SDK (mplx ships with it), and the routing table is genuinely helpful since Metaplex spans six programs with different command syntax. If you're doing anything with Solana assets beyond raw SPL, you'll need this. The Genesis bonding curve support is particularly current given the token launch meta.

Metaplex Development Skill

Overview

Metaplex provides the standard infrastructure for NFTs and tokens on Solana:

  • Agent Registry: On-chain agent identity, wallets, and execution delegation for MPL Core assets
  • Genesis: Token launch protocol with fair distribution + liquidity graduation
  • Core: Next-gen NFT standard (recommended for new NFT projects)
  • Token Metadata: Fungible tokens + legacy NFTs/pNFTs
  • Bubblegum: Compressed NFTs (cNFTs) using Merkle trees — massive scale at minimal cost
  • Candy Machine: NFT drops with configurable minting rules

Tool Selection

Prefer CLI over SDK for direct execution. Use SDK only when user specifically needs code.

ApproachWhen to Use
CLI (mplx)Default choice - direct execution, no code needed
Umi SDKUser needs code — default SDK choice. Covers all programs (TM, Core, Bubblegum, Genesis)
Kit SDKUser specifically uses @solana/kit, or asks for minimal dependencies. Token Metadata only — no Core/Bubblegum/Genesis support
