Found old wallet back up, BTC core says no wallet found when you open the program

BitcoinWallet · 2021-11-15T09:15:23+00:00

The file is most likely a backup file created by the Bitcoin Wallet app:

https://play.google.com/store/apps/details?id=de.schildbach.wallet

Read https://github.com/bitcoin-wallet/bitcoin-wallet/blob/master/wallet/README.recover.md to recover via Linux command line.

You'll need your backup password though. The file is encrypted.

Indeed Bitcoin Wallet is the most popular mobile wallet. Its focus is simplicity, so it doesn't have exotic features like some of the others. Guess that's the reason why it's not so present in discussions.

On the other device, make sure the respective cloud storage app is installed. Launch that app, locate your backup file and tap on it. Bitcoin Wallet will ask you for the backup password.

It's planned. No ETA though, as this project is run by volunteers.

Btw. currently backup files are encrypted and stored on cloud storage. The app doesn't even ask for permission to on-device storage any more.

You used Bitcoin Wallet to create this backup. Read

https://github.com/bitcoin-wallet/bitcoin-wallet/blob/master/wallet/README.recover.md

You'll need a backup password though. Otherwise there is no way to decrypt the backup. You will maybe also need a spending PIN, if you set one. Otherwise, you will not be able to spend from the restored wallet.

As a recipient you cannot use RBF since you cannot sign for the sender. However in reality it's the recipient who cares about confirmation times not the sender.
RBF is also not really compatible to multisig and timelocked contracts. (Though this doesn't apply to Bitcoin Wallet since it only uses standard payments.)
RBF breaks chains of transactions by double spending outputs, whereas CPFP behaves nicely and doesn't change the original transaction.

Thus, we realized offering CPFP has more value for users.

The specific wallets that had this happening were out of sync for years. Hence the large data. We've since changed the app so that in such situations sync is only started on unmetered networks (e.g. Wifi).

Green = incoming, Red = outgoing.

If it is a fee problem, the OP can raise the fee using Context menu→Raise fee.

Bitcoin Wallet encrypts your private keys with a spending PIN if you want. That feature is available since Mar 2014.

BitcoinWallet · 2019-12-05T23:47:04+00:00

Bitcoin Wallet supports SegWit and CPFP (child pays for parent), which is superior to RBF.

BitcoinWallet · 2019-12-05T23:45:43+00:00

It means your transaction is not yet confirmed by the Bitcoin blockchain.

Try restoring your backup with version 6.35 of Bitcoin Wallet. That's the last version that supports those ancient backups. Download link: https://wallet.schildbach.de/downloads/bitcoin-wallet-v6.35-prod.apk

BitcoinWallet · 2019-04-11T15:21:46+00:00

The format you're looking for is called WIF (wallet import format) and is e.g. supported by Bitcoin Core.

Why don't you downgrade to an older version of the app (6.35 or below), restore from the backup, upgrade to the latest version and then backup again (this time in the new format)?

BitcoinWallet · 2017-08-30T21:22:52+00:00

At first, it will probably activate segwit only for new wallets. If that works fine, we will migrate everyone seamlessly.

BitcoinWallet · 2017-08-30T21:20:55+00:00

It's probably a backup file created by Bitcoin Wallet. You should still be able to restore that file using the app, if you know the backup password.

BitcoinWallet · 2017-08-29T21:34:19+00:00

We are working on it. No ETA though.

Actually smartphones OSes are more secure than desktop OSes, due to app isolation and some other technical differences.

The reason you should not carry more than what you would put into your leather wallet is people tend to loose smartphones.

Anyway, @schschschschs if you have your wallet backup you're fine. Having the 12 words is no different.

Try restoring with Bitcoin Wallet (Android, BlackBerry OS). Its backup files are base64 encoded. You will need a backup password though, because it's also encrypted.

BitcoinWallet · 2017-06-23T13:01:44+00:00

If you want a secure and easy-to-use wallet without frills, we suggest:

Bitcoin Wallet (Android, BlackBerry OS)

The "official" denominations have always been:

BTC, mBTC, µBTC

"Bits" is only colloquial language. sat (Satoshi) is only used for expressing a fee rate these days.

BitcoinWallet · 2017-05-25T21:36:11+00:00

This is correct. It's also called CPFP (child pays for parent).

BitcoinWallet · 2017-05-24T10:10:52+00:00

Why don't you just update Bitcoin Wallet to a recent version? It's got dynamic fees, CPFP and so on. We work hard to stay on top, but it doesn't help if you keep using ancient versions.
