Authz
ℹ️info
Terra's Authz module inherits from the Cosmos SDK's authz module. This document is a stub and mainly explains important Terra-specific notes on how it is used.
The authz (message authorization) module allows users to authorize another account to send messages on their behalf. Certain authorizations, such as the spending of another account's tokens, can be parameterized to constrain the permissions of the grantee, such as setting a spending limit.
