What Is SPL Token?

Definition

An SPL token is the standard fungible token format on the Solana blockchain, equivalent to ERC-20 on Ethereum.

SPL stands for Solana Program Library. SPL tokens are fungible tokens created using Solana's Token Program — the on-chain program that handles minting, transferring, and burning tokens on Solana.

Every SPL token has a mint address (the unique identifier), a supply, decimals (how divisible the token is), and optional authorities (mint authority, freeze authority). Token metadata (name, symbol, image, description) is stored separately via the Metaplex Token Metadata program.

SPL tokens power memecoins, governance tokens, stablecoins, and utility tokens across the Solana ecosystem. Major SPL tokens include USDC (on Solana), Bonk, Jupiter (JUP), and Raydium (RAY).

You can create your own SPL token with CoinDevTools in minutes — no Rust or Solana CLI required. Just connect a wallet, configure your token parameters, and confirm one transaction.

Metaplex Token Metadata

Metaplex Token Metadata is a Solana program that stores human-readable information (name, symbol, image, description) for SPL tokens.

Mint Authority

The mint authority is the wallet address authorized to create new tokens for an SPL token on Solana. Revoking it permanently locks the token supply.

Freeze Authority

The freeze authority is the wallet address that can freeze (prevent transfers of) any token account for an SPL token on Solana.
