This release adds BBQr and updates UR.

• Export and import QR codes in UR or BBQr format.
• More efficient QR scanning.
• Available balance now on display in the spend view.
• Fixes a bug where non Fully Noded wallets (Bitcoin Core wallet accessible via the advanced button) would hang on a never ending spinner when creating a transaction.
• Adds an animate button to UR Qrs (BBQr will automatically update).
• Xprv now included in Bitcoin Core hot wallets in the wallet backup QR/file.
• Tor updated to v408.11.2.
• DNS port removed from Tor config options.
• Fixes a bug when importing a psbt may result in a never ending spinner.

Join Market

This release includes full Join Market functionality:

• maker
• taker
• fidelity bond

Fully Noded can now control your JM wallet via the JM rpc api.

To use this you'll need to be running JM and Tor.

• create a .joinmarket/ssl directory and cd into it (your JM data directory)
• in a terminal run openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -sha256 -days 365
• when it prompts you for information just leave all blank except for the domain or fqdn which you can enter as localhost
• test your daemon works by starting your jmvenv as normal, cd into scripts, and running python jmwalletd.py
• it should start, then you can configure a tor hidden service for port 28183
• restart tor to ensure the hidden service is active
• take your hidden service hostname and add it to FN as a new node, along with the cert you created earlier, just the base64 text is needed, run cat cert.pem and paste only the text not the header and footer
• FN will automatically recognize that as a JM node and allow you to enable it when a normal onchain node is also running
• go to any wallet in FN -> utxos and tap the mix button

Easy Taproot

Features

• create single sig Taproot wallets with ease (BIP86), private keys are stored on the node which is why you need to enter a password to encrypt them
• interact with the wallets which do not exist on the active node, allowing you to recover them to the active node, delete them, and see their details
• "send to wallet" button on the send view which allows you to easily generate receive addresses from all wallets regardless of which wallet/node is active
• better handling of locked wallets during the signing flow (will prompt you to enter the password)
• paste, upload, scan bip39 mnemonics on the wallet creator to easily create wallets
• create multisig wallets with signers where the seed words were deleted
• more robust UR support, previously was hard coded to only work with segwit, it now works with most script types, and xprvs
• ability to encrypt private keys for taproot wallets

Fixes

• output verification for multisig addresses could have gotten stuck
• UI fixes/improvements, the network icon color now reflects the actual Bitcoin Core icon color for each network
• actually utilize the blockheight when recovering wallets
• do not allow 1/1 msig creation
• better UX when creating wallets via signers
• better error/UX if wallet does not exist on the active node

Signer Revamp

Highlights:

This is a major update which give the Signer tab a makeover. Much more functionality is now included. Most importantly FN now encrypts and saves your signers BIP48 and BIP84 public key descriptors and their ur:crypto-account counterparts so that you can easily export a cosigner or single sig watch only wallet to other apps via Airgapped QR scanning. This vastly improves Fully Noded compatibility with other wallets such as; Blue Wallet, Sparrow, Keystone, SeedSigner, Passport and others.

The root xpub is now encrypted and saved so that you may easily share it in ur:crypto-hdkey format to Casa App to create multi-sig wallets or with any other app that suppports non hardened derivations for creating watch-only wallets.

The beauty of exporting the signers in this way is you would not even need to have the wallet on Fully Noded, it can simply act as a stupid signer. The external wallet can create the psbt, then FN will be able to sign for it and broadcast, it always had this ability but it was not easy to export signers to other wallets.

You may now delete seed words and edit or delete passphrases from your signers leaving only the derived public key descriptors saved on the device. Changing or deleting the passphrase will change the derived cosigner/single signature export and have other major consequences such as the inability to sign for any wallet that used the previous passphrase.

A new "Prompt for passphrase" feature can be found by navigating to settings > security center > (scroll to bottom) prompt for passphrase. FN will still create and attempt to sign transactions as normal, however if any transaction is incomplete and needs more signatures when you go to tap the sign button you will be prompted to enter a passphrase, this passphrase will overwrite all existing signers passphrases and will be added to all seeds. This way FN never saves your passphrase at all and is great for plausible deniablity.

A new wallet export QR in wallet details which is compatible with Sparrow wallet and will hopefully gain wider adoption. It also of course works with Fully Noded for importing and may replace the backup QR in a future update. The difference is that the backup QR holds some useful details about your wallet (its label and block height) whereas the export QR is designed for greater cross wallet compatibility, holding only the ur encoding of the bitcoin output descriptor of your wallet.

New features:

• export signers to easily create watch-only multi-sig and single-sig wallets with many other software and hardware wallets (Sparrow, Blue Wallet, Passport, Keystone, SeedSigner, Seed Tool, and of course Fully Noded)
• edit/delete your passphrase via signers
• new export wallet QR in wallet details (compatible with Sparrow wallet keystores and descriptors)
• export cosigners to Casa App to create multi-sig wallets via signers
• create wallets directly via signers
• delete seed words but keep the signer, allows for storing the cosigner and watch-only xpubs to easily create new wallets or export to other apps even if seed words are not held on the device
• many more fiat currencies when using the blockchain.info api
• settings > security center > prompt for passphrase will enable a new feature which will ask you for a passphrase to sign transactions with each time you tap the sign button. This passphrase is not remembered and is applied to all seeds and overwrites all existing saved passphrases when attempting to sign
• improved 2FA
• local biometric authentication now required to display signers seed words
• signers now act as a recovery tool as you can tap the + button to create wallets directly from signers
• signer network is now set automatically depending on the current nodes network

Bug fixes:

• UX bugs around creating Bitcoin Core wallets and importing private keys
• a possible bug where a signed raw transaction was not passed to the transaction verifier, instead the psbt was passed
• a bug where Bitcoin Core 22.0 changed the way raw transactions were serialized so that addresses were given as a single key value pair and not an array, this could have resulted in the transaction verifier not displaying all info for inputs/outputs
• display an error message if testmempoolaccept fails
• speed up single sig wallet creation by relying on UserDefaults instead of dynamically fetching chain and blockheight every time the view loads
• 2fa bug where active wallet view refreshed when it shouldn't

Fully Noded - v0.2.24

Feature

This update adds a flexible, powerful and highly secure means of backing up your critical data to the iCloud.

In order to use the feature the user must enter an "encryption password".

FN hashes the password once and uses the resulting hash to encrypt and decrypt your data. FN never stores this hash or the password, therefore all iCloud functionality is 100% manual and the user must initiate any action by going to settings and tapping the actions.

FN hashes the hash of your encryption password, saving the double hash to the devices local keychain so that when you go to decrypt it we can verify the hashes match before actually attempting to decrypt data. Otherwise the user could possibly input any password and decryption would fail or a single backup would be become partially bricked with multiple encryption keys.

To reset the double hash used for verification you need to delete the iCloud backup, no password required to do so.

For kill switch functionality of the iCloud back up just tap "Delete iCloud backup". You can then create a new backup with a new password.

It is recommended not to use the same password as your unlock password because FN remembers the hash of your unlock password which would then match the iCloud encryption key, reducing the security of your data.
