Banker

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.
