Token Dev API

Understand the boundary

The word token is overloaded. In this topic it means a digital asset represented on a blockchain, not an access credential or a language-model billing unit. An asset record should carry a network identifier and a contract or mint identifier before it carries a display symbol. Symbols are presentation metadata and should not be used as a unique identity key.

A practical starting project

Design a read-only asset response containing chain, asset identifier, integer amount as a string, decimal precision, observation time, and provenance. Add separate fields for optional display name and symbol. Test two unrelated assets with the same symbol and one asset whose metadata is unavailable. The client should still preserve identity and display an honest unknown state.

Where integrations go wrong

Do not interpret a token balance as a verified market value, redemption right, or investment recommendation. An RPC response and an issuer’s documentation answer different questions. Keep signing and custody outside a read-only data service, and document whether a displayed balance is provisional or based on a stronger finality policy.
