Also known as: Asset Metadata, Token Descriptive Data

Definition

Token metadata is descriptive information associated with a token, such as its name, symbol, decimals, logo, issuer links or other attributes. It helps interfaces display assets but should not be treated as proof of authenticity.

What it means and why it exists

Token metadata is descriptive information associated with a token, such as its name, symbol, decimals, logo, issuer links or other attributes. It helps interfaces display assets but should not be treated as proof of authenticity.

How it works

Some information is returned by token contracts, such as ERC-20 name, symbol and decimals; other information comes from token lists, registries or off-chain hosting. A wallet may use these fields to show readable amounts and icons. A payment processor must still identify the asset by network and contract or mint address, not a display label.

Technical details worth understanding

The decimals value affects conversion between integer base units and user-visible quantities. A token with six decimals represents 1.5 tokens as 1,500,000 base units. Metadata can be mutable, missing or inconsistent across sources. For NFTs, metadata may point to externally hosted files with separate availability and integrity concerns.

What can go wrong

Fraudsters can create a token named 'USDT' or copy a stablecoin logo. A recognizable symbol is not evidence that the token is issued by the genuine organization. Broken metadata hosts can make an asset appear blank without changing its actual balances.

Practical checks

When onboarding a token, pin its network and canonical contract or mint address in an allowlist. Display metadata is useful for UX but not authentication. Convert values using the asset's verified decimals; test unusual symbols and missing icons to ensure they cannot alter business logic or overwrite trusted identification.

ERC-20 Token Standard — EIP-20.

Example

A customer attempts to pay a $40 invoice using a token displaying a familiar dollar symbol. The processor rejects it because its contract address differs from the merchant's approved asset list, even though its logo and decimal settings match.

Comparison

Metadata describes presentation; contract or mint identity determines which asset exists on a specific chain. A ticker symbol is not a unique global identifier and does not imply a peg or issuer guarantee.

Key Takeaway

The decimals value affects conversion between integer base units and user-visible quantities.
