NUNCHUK 0.9.7

Nunchuk 0.9.7 is out and is a major upgrade over our previous releases. Here it is at a glance:

  • [NEW FEATURE] Connect directly to a Core node.
  • [NEW FEATURE] Verify address on-device.
  • [NEW DEVICE SUPPORT] CoboVault in singlesig mode (multisig pending on new Cobo firmware).
  • [NEW DEVICE SUPPORT] PIN Input for Trezor One.
  • Minor fixes and improvements.

Read on for a quick summary of what it all means.

Connect directly to a Core node

Starting from 0.9.7, users will have two options for the Nunchuk wallet backend: an Electrum server or a Bitcoin Core node.

The Electrum server option makes the most sense for those who want secure, remote access to your Core node on-the-go, and/or the ability to share your node with other people. (Electrum is a light wrapper around a Core node).

On the other hand, for those who don’t have those needs and don’t want to deal with Electrum, you can now leverage your Core node as the Nunchuk wallet backend. Nunchuk will connect directly to your Core node over RPC, without going through any other intermediary software.

Verify address on-device

When it comes to Bitcoin wallets that delegate signing to other software/hardware — which includes all multisig wallets, a crucial security feature is the ability to verify with the signers that your displayed receive and change addresses are legitimate. Nunchuk 0.9.7 allows you to quickly do this via the Home and Receive screens.

Cobo Vault support

Cobo Vault is one of the few hardware vendors that specialize in air-gapped signing via QR codes. Nunchuk 0.9.7 fully supports Cobo in single-sig mode.

Cobo in multisig mode will also be coming soon, pending a new Cobo firmware that removes (unnecessary) restrictions on BIP32 derivation paths.

PIN Input for Trezor One

Support for the Trezor One was previously hampered due to the Trezor One’s lack of a native touch screen input. We have added a PIN input screen to help users leverage their legacy Trezor One devices. You can now use Trezor One both in singlesig and multisig mode.

Icons, icons, icons

Last but not least, we have added customized icons for various device types.
