Thank you for the delivery, @3yekn! We will look into it as soon as possible.

Hi @3yekn. I'm trying to set an xpub with the UI, but when trying to scan a QR code the UI tells me to allow camera permissions. However, my browser never actually asks for it (this happened on Firefox, and then also on Chrome). Console error logs from Firefox:

Uncaught (in promise) TypeError: 'camera' (value of 'name' member of PermissionDescriptor) is not a valid value for enumeration PermissionName.
    open qr-decode-xpub.vue:47
    ...

Additionally, trying to input an xpub manually does not seem to work as expected:

Finally, https://github.com/hashed-io/native-bitcoin-vaults-UI is now 404'ing for me, has it been privated?

Hi @lucasvanmol - the XPUB format requires the fingerprint and the derivation path. It isn't clear from the error message though- I will create a new issue so that we put an example one on the screen. If you scan it in from BlueWallet (recommended), it will be the right format but we also support copy/paste of course.

The format should look like this:

[DDB3F11E/48'/0'/0'/2']Zpub74CJEA8Vx5yub6CiSuoFMLESzh2TzuaXXcZ4BrA9wntbg4kR9sCUrHqPQUCu5YMXRD6n624FUozZd8r5C41ProRqs3G6Mp2Zieu4RrWKdor

The camera error is a browser permission I believe. @jmgayosso - can you provide instructions on how to configure this?

And for the repo, it was inadvertently made private but it is public again now. Let me know if you would like me to generate some data for you or send tokens to your address if you are connecting to wss://n1.hashed.systems.

Unfortunately, BlueWallet does not have a testnet mode but we can create and fund a small multisig wallet with you for end-to-end testing if it helps.

[lucasvanmol]

Would love some data for wss://n1.hashed.systems. Also, could you add appropriate LICENSE files to bdk-services, native-bitcoin-vaults-UI and nbv-ur-codec?

[mgravitt]

@lucasvanmol ok, I will create some data, vault/wallet, and we will also deploy an instance of the UI to make it easier to test. You will need to download BlueWallet though if you want to test importing the vault into a signer. This will also be needed for milestone 2, which includes signing the PSBTs and finalizing/broadcasting the transaction. I will report back when this is ready.

Also, I will update the LICENSE files as you mention. thanks

[mgravitt]

@lucasvanmol You can find a deployed instance at https://nbv.hashed.systems

Our substrate work is deployed at wss://n1.hashed.systems, which is where the UI points to.

I created a vault for two pretend users. I can send you to the mnemonics for those accounts. I pinged you on Element, and I can share them there.

I've also updated the LICENSE in all repos.

[lucasvanmol]

Hi @3yekn, thank you for your patience and your help so far. Before we accept the delivery, we'd like to ask you for a few things:

• Could you make sure the table included in this delivery is identical to the one in the application?
• Could you edit the application document to include the changes you decided on, notably integrating BlueWallet instead of Spectre? Notably this section, and this one. You can edit them down quite a bit, just mention the technology you ended up going with.

Thanks!

Hi @lucasvanmol, thanks for the update. I made the requested changes on this PR for the Delivery and submitted a new PR to the Grants-Program repo. That PR is located here: w3f/Grants-Program#987

[lucasvanmol]

Thanks for the changes @3yekn ! You can see my final evaluation here. I'll notify the finance team to pay your invoice.
