Exploring a 1-of-2 Multi-Sig Setup with Hidden Keys

So I got this 1-of-2 multi-sig setup. Seed A is in location A, Seed B in location B, and public keys are in location C. If seed A gets leaked, can the attacker still access my funds since they don’t have the public key for seed B?

This is for wallets with smaller funds, so I’m being extra cautious.

Just to clarify, if you’re using Electrum, you need the cosigner's Master Public Key in your wallet info. The public keys from transactions can’t be used for other addresses.

Maybe, maybe not. But if it’s a targeted attack, odds are they know your address. Why not go for a 2-of-3 multisig? It’s safer.

Seed splitting is risky, says Antonopoulos. Hard to recover your wallet if you don’t have the full seed.
