# Blockchain account ID (CAIP-10) (`caip10_account_id`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Chain-agnostic identifier of an account defined by CAIP-10: a CAIP-2 blockchain ID, a colon and the account address in the format of that chain, up to 128 characters. It tells both the network and the address, which an address alone often does not.
