Take your best guess

I guess it depends on direction. Going to BTC to ETH would only be efficient with a snark and would therefore be trustless. Going from ETH to BTC is more complicated and I guess could be done via the ETH sync committee in ZK via BitVM or just with a trusted threshold sig. Both of these are honest majority though.

Not sure how quilibrium gets you to trustless though. I haven't looked into their MPC scheme but I assume it's honest majority to ensure liveness?

Oh also I guess the BTC -> ETH direction also would introduce a trust assumptions if you just verify the PoW rather than all STF so you lose correctness under a 51% attack rather than just consistency which is all native btc loses, so I guess that's a degradation over trustless as well.
