Question
What is wrong with the signatures here?
My thoughts and a bit of context
So basically we have two inputs here. Both are from multisig addresses. The difference is that the second one is just P2WSH.
The first one is mostlikely fine. The second one is my concern. So let's look at witness signatures for the second input.
We have three signatures:
- 3045022100cd569e7f8e5fb6490ef3240d68abdd147f0c3ce4e77bcfd59f587b9a14848bdb02207fe31882d22518af84d3961809b6133c06b34ce6f91c1e579dcff0c58b7519d3
- 304502210099699d11f3fa427c2739580de08fc3a305202a6b1f39c01d8f82e6ad8a9b191902205153041c9a291b81c3ef94cba9d22f3a8df6ee45faab13407ec8a56843051043
- 3045022100b57e36875906add1edeb57badc92f5b4287f9e33b609fad5ae35912cdc0596ff022073338c6e14637dfc11abdb18c2396a58b8e537670d06084981799f64bcd7c3f401
First two are generated by hardware wallets. The third one is created by Bitcoin Core. So basically each of these signatures claims to be 0x45 (69 bytes long). But the third one has additional 01 at the end.
Questions
Is this the reason of the error?
If not what is this additional byte?
Any clues what is wrong with this transaction?
