Oh, sorry i misunderstood
And sorry, it took a moment to reply, cause I had a client-call in the middle of my answer.
You are right, there´s just a bunch of different pubKeys and not all of the wallets you´re holding.
You may need another option, like a cli/dev-tool to derive the pubKey from your privKey.
Just an important reminder:
NEVER give your seeds or privKey to anyone else!
Okay, not sure how familiar you are with programming or consoles, but TrustWallet has a
WalletUtility, which probably can help you here:
Or maybe an admin can point you in the right direction.
Good luck, mate =)
