Metadata Update Authority

The account authorized to modify an NFT's or token's on-chain metadata, including name, symbol, URI, and attributes. In Metaplex's token metadata standard, this authority can update mutable metadata fields. Revoking or transferring update authority is a trust signal — immutable metadata means the creator cannot alter the NFT's properties post-mint.

Metaplex Token Metadata

The Metaplex Token Metadata program (metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s) that attaches rich metadata to any SPL token or NFT. It creates a PDA-derived metadata account storing: name, symbol, URI (pointing to off-chain JSON), creators array, seller fee basis points, and collection info. The de facto standard for NFT metadata on Solana.

Ramo

Mint Authority

The pubkey authorized to mint new tokens via the MintTo instruction. Set at mint creation and can be changed or revoked (set to None) by the current authority. Revoking mint authority makes the supply fixed—critical for trust in fungible tokens. For NFTs, mint authority is typically revoked after minting the single token.

Ramo

NFT (Token Não Fungível)

A non-fungible token on Solana—an SPL token with 0 decimals, supply of 1, and revoked mint authority. The NFT's metadata (image, attributes) is stored off-chain (Arweave/IPFS) linked via the Metaplex metadata account's URI field. NFTs can be standard, compressed (cNFT), programmable (pNFT), or Core assets, each with different trade-offs.

Metaplex Core NFT

Metaplex's latest NFT standard (mpl-core) that uses a single account per asset instead of multiple accounts (mint + metadata + master edition + token account). Core NFTs are cheaper to mint (~0.003 SOL), have built-in plugin support (royalties, freeze, attributes, app data), and native collection-level operations. Designed to replace the legacy Token Metadata standard.

Ecossistema de Tokensfreeze-authority

Freeze Authority

The pubkey authorized to freeze and thaw token accounts, preventing transfers. Set optionally at mint creation. When a token account is frozen, no transfers, burns, or closes can occur until thawed. Used for regulatory compliance (e.g., USDC) and security (freezing compromised accounts). Can be revoked by setting to None.

Programa SPL Token

The original Solana Program Library token program (TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA) that implements fungible and non-fungible token operations. It manages mints (token definitions) and token accounts (balances). Core instructions include InitializeMint, MintTo, Transfer, Burn, Approve (delegation), and Revoke. All SPL tokens on mainnet before Token-2022 use this program.

Solana Program Library (SPL)

Solana Program Library—a collection of on-chain programs and client libraries maintained by Solana Labs. Key SPL programs include Token, Token-2022, Associated Token Account, Memo, Name Service, Stake Pool, and Account Compression. SPL programs are deployed to well-known addresses and serve as the standard building blocks for Solana applications.

Token-2022 (Extensões de Token)

The next-generation token program (TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb) that extends SPL Token with configurable extensions. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, metadata, and more. Token-2022 is backwards-compatible with SPL Token for basic operations.

Mint

An on-chain account defining a token type. A mint specifies: supply (total minted), decimals (0 for NFTs, 6 for USDC, 9 for most tokens), mint authority (who can mint), and optional freeze authority. Each unique token (USDC, JitoSOL, etc.) has exactly one mint account. Mint address serves as the token's unique identifier.
