The Banker's main purpose is to handle balance changes of native coins within Gno chains. This includes issuance, transfers, and burning of coins.

The Banker module can be cast into 4 subtypes of bankers that expose different functionalities and safety features within your packages and realms.

Banker Types

  1. BankerTypeReadonly - read-only access to coin balances
  2. BankerTypeOrigSend - full access to coins sent with the transaction that called the banker
  3. BankerTypeRealmSend - full access to coins that the realm itself owns, including the ones sent with the transaction
  4. BankerTypeRealmIssue - able to issue new coins

The Banker API can be found under the std package reference.
