<p>The <code>gRPC</code> approach seems interesting.</p>
<p>It's basically <code>protobuf</code> over HTTP/2 by Google (very well supported and documented).</p>
<p>It's pretty much self-contained and very low on dependencies while still covering all typical needs like objects ser/deser, param validation, routing, server, and client.</p>
<p>As we already use protobuf and Google stack of Java libraries, this feels like a good fit for Bisq.</p>
<p>Not sure if there are no hidden blockers though, would require more research!</p>
