XUMM error: fails local checks: Invalid Signature

[xrp_chiefs]

Title says it all

Looking to diagnose what could possibly be the problem with my attempt to send money from one of my wallet addresses to another. Any ideas on where to start?

I’m not an expert and know next to nothing about Xumm but that message seems to indicate that the password or whatever you entered as part of sending the transaction was incorrect.

I think fails local checks means the transaction wasn't submitted to the ledger. Something went awry. Are you sure you're sending to a valid address? That error suggests you have a malformed transaction. The XUMM wallet shouldn't have let you construct a malformed transaction but it can happen. The first thing to do would be to check your inputs. Like if you entered an invalid send amount. Make sure you're inputs are correct. 

It may be a bug in the wallet. If you have sent a tx from this wallet before and it succeeded then don't worry. Another wallet will be able to sign a tx. Trying again may work but you might want to submit a bug report to the developers. 

The worst case scenario is you don't have the right key but I don't think so. Maybe what BillyOckham is saying. If your key is encrypted with a password and you enter the wrong password. "fails local checks" usually means you created an invalid transaction.

I think that in Xumm you need to prove you are the owner by entering a password on send.  Agree fails local check likely means it wasn’t submitted.

In the Xumm context the signature is the encryption password I think...  hence my guess you just entered the password wrong.

You could try a false password on a send and see if message same.  Also try a small test send with what you think is valid password.

No the invalid signature means he signed a transaction with his private key and the signature wasn't valid. If the private key is an encrypted blob of bytes then the encryption scheme may have missed that the password was invalid. The unencrypted blob of bytes would be the wrong key, then the wallet would have signed a transaction with the wrong key. But what about multisig? I'd think signing with a different key shouldn't throw an error until after it's submitted to the network. 


Ok I looked into this further. Failed local checks IS thrown by the server.

So the tx is sent to the network and rejected due to a bad signature. You're right it could be a bad password. 

@xrp_chiefs if you forget your password but you have the ripple secret then you can use another wallet. You should always have a copy of your secret key. It starts with an 's'. This is an example secret key: snoPBrXtMeMyMHUVTgbuqAfg1SUTb

Hey! The founder of XRPL Labs, creators of XUMM here

Did you perhaps import your XUMM account from a HEX private key? Or even imported the "MessageKey" as "Family Seed" during account import?
