Interesting, we'll look into it.

If you're adding multiaddrs, not sure if these will help you or not:

We built an extension trait for ENR to add support for libp2p-related things:
https://github.com/sigp/lighthouse/blob/stable/beacon_node/lighthouse_network/src/discovery/enr_ext.rs

Also, because I use this around in a few places, I made an effort to integrate it into Enr at one point, so you could just enable multiaddrs via a feature, but it got stalled:
sigp/enr#60
