# gRPC transport notes

> **Status: Note.**

A non-normative note, not a declared family. v2 has no normative gRPC transport, because the conformance suite has no gRPC client or behavioral witness.

| Field | Value |
| --- | --- |
| **witness:** | `unwitnessable` |
| **technical:** | `experimental` |
| **adoption:** | `none` |
| **advertised as** | not advertisable; v2 has no `grpc` discovery record |

[`openwop.proto`](https://github.com/openwop/openwop/blob/main/spec/v2/ext/grpc-transport/openwop.proto) is a sketch only. It is not a v2 contract.
