What Is Token Metadata?
Definition
Token metadata is the human-readable information attached to a token — name, symbol, description, image, and attributes that wallets and block explorers display.
Without metadata, a token is just a number on the blockchain. Metadata gives it identity.
- Solana (Metaplex) — stored on-chain. Includes name, symbol, URI (JSON with image/description). Can be mutable or immutable.
- Ethereum/Base (ERC-20) — name/symbol hardcoded in contract. Images added via block explorer submission.
CoinDevTools handles all metadata during creation. On Solana, your image is uploaded to IPFS and Metaplex metadata is stored on-chain automatically.

Metaplex Token Metadata
Metaplex Token Metadata is a Solana program that stores human-readable information (name, symbol, image, description) for SPL tokens.
SPL Token
An SPL token is the standard fungible token format on the Solana blockchain, equivalent to ERC-20 on Ethereum.
ERC-20 Token
ERC-20 is the most widely used token standard on Ethereum and EVM-compatible chains, defining how fungible tokens are created and transferred.
Decimals (Token Precision)
Decimals define how divisible a token is — a token with 9 decimals (standard for Solana SPL) can be divided into 0.000000001 units, while 18 decimals (ERC-20 standard) allows even finer division.
