# `authz`

## Contents

## Abstract

`x/authz` is an implementation of a Cosmos SDK module, per [ADR 30](../../../architecture/adr-030-authz-module.md), that allows
granting arbitrary privileges from one account (the granter) to another account (the grantee). Authorizations must be granted for a particular Msg service method one by one using an implementation of the `Authorization` interface.
