It'd be great if @anonworld could attest to my ownership of assets of any wallet I already verified with my Farcaster account without me having to connect it and verify it with @anonworld  again.

I know nothing about how the zk proofs work so no clue about feasibility. Just know it'd be a much better user experience.

Building /warpcast and /farcaster

I don't think it's possible without additional assumptions. When you connect a wallet on Farcaster, it's on-hub Verification Message, but not onchain IIRC. Creating a proof would require some sort of multisig cosigning service to verify "the stateroot of the hub and the stateroot of the Blockchain were X & Y at time T". You could have an Eigenlayer AVS that acted as this cosigning committee though.

Sounds like the verification would actually be verification of ownership of one of the connected accounts? Or perhaps verification of Warpcast sign in?

For most people that would be good enough, just technically you wouldn’t be verifying ownership of the claimed account because you’re not signing with it
