Title: 2 of 4 wallet confirmed transfer on a single signature
Post by: ZAFinMan on June 04, 2019, 08:13:19 PM
Can someone please advise how a transfer went out on a single signature?  Thanks.

I'm no expert on multi sig, but can you post the txid?

It can't unless it was badly set up.

Post the TXid so we can check but the only way it can be done is if someone got two private keys or someone managed to do something "interesting" with the set up (i.e. directing you to an infected wallet to host a key they already had).

perhaps a 2-of-4 multisig address which was generated from:
- only 3 distinct public keys, so 1 of them can sign once but treated as 2 signers, or
- 4 different public keys but 2 of them were originated from the same privkey hex
requires a wallet that stores privkeys in hex format, so that can sign both its compr and uncompr public keys at once

if you can post its redeem script, we can figure it out easily

how do you know it "went out with one signature"? did you actually check your scriptsig field in your transaction and saw only 1 signature there or are you just assuming that because you clicked send and it sent the transaction? if is is the later (which would be my guess) it is because your wallet already contained at least 2 private keys and signed the transaction using them!
