Authz Grants

Authz Grants or Authorization Grants are a feature provided by the Cosmos SDK to users and delegators to allow the delgators (granter) to grant authorization (grant), or in simple words permission to another account (grantee) to perform actions on behalf of the user (allowed actions are explicitly specified at the time of asking for an authz grant, along with an expiration date and monetary limits of the grant). This essentially means that the grantee cannot do anything with the granter's account that they did not ask explicit permission for.
