<ul>
<li>DID Controllers leverage the Cosmos SDK's <code>x/accounts</code> std interface for WAA.</li>
<li>DIDs are represented by a <code>x/did</code> controller and are required to state the

<li>General Sign/Verify methods are provides from the QueryServer for HTTP requests.</li>

<blockquote>
<p>The service module is responsible for managing decentralized services. Services
on the Sonr network are essentially on-chain MultiSig wallets that are
represented by a NFT. Service admins are represented by
a <a href="2--Modules-Overview.md#x-did"><code>x/did</code></a> controller and are required to state
the service's scope of access, and which map to the services' capabilities.</p>
