Non-Transferable Token

A Token-2022 extension that prevents tokens from being transferred between accounts, making them soulbound. Non-transferable tokens can only be minted to and burned from accounts. Use cases include achievement badges, identity credentials, governance participation tokens, and certifications.

A Token-2022 extension that prevents tokens from being transferred between accounts, making them soulbound. Non-transferable tokens can only be minted to and burned from accounts. Use cases include achievement badges, identity credentials, governance participation tokens, and certifications.

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a building block that connects one definition to the larger Solana system around it.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

SPL assets, token standards, metadata, and NFT primitives.

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Branch

Token-2022 (Token Extensions)

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.

Off-Chain Metadata (JSON)

The JSON file referenced by an NFT's metadata URI that contains the full description, image URL, attributes, and properties. Typically stored on Arweave (permanent, ~$0.01), IPFS/Filecoin, or Shadow Drive. The JSON schema follows the Metaplex standard: name, description, image, animation_url, attributes[], properties{files[], category}.

Token Ecosystem

NFT Staking

The process of locking NFTs in a program to earn rewards, typically in the form of a project's token. Staking programs verify NFT ownership and collection membership, track staking duration, and distribute rewards proportionally. On Solana, NFT staking is commonly implemented using Metaplex's freeze delegate or by transferring the NFT to a program-controlled escrow account. Rewards incentivize holding over flipping.

SPL Token Program

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.

Token Ecosystemsoul-bound-token

Soulbound Token (SBT)

A non-transferable token permanently bound to a specific wallet, representing identity, credentials, achievements, or reputation. On Solana, soulbound tokens can be primarily implemented using Token-2022's non-transferable extension or transfer hooks that reject transfers, which prevents any transfer after minting. Used for proof of attendance, skill certifications, and on-chain identity.

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.

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.
