Some wallets (eg Trezor Suite) do not allow you to create a second account if the first one is unused. Sparrow does, however. Otherwise all correct.

Sparrow v2.3.1 has been released to restore BIP32 derivations for consolidation payments in PSBTs.
In addition, hiding amounts is now supported, and the keystores that signed a multisig transaction are now shown on the transaction tab.

Frigate v1.2.0 has been released.
Frigate is an experimental Electrum server testing efficient Silent Payments scanning with ephemeral keys.
The major feature in this release is GPU acceleration of the cryptographic computation required for Silent Payments scanning. This provides a dramatic (over 10x) performance improvement over CPU computation, and makes a public Silent Payments Electrum server a practical reality for the first time.

Silent payment addresses are a new form of static payment address, where the actual bitcoin address that you send to is determined from both the silent payment address and the transaction inputs.
This means you can pay to the same silent payments address while ensuring bitcoin addresses are never reused. This both simplifies the payment experience and makes it more private, at the cost of increasing the burden on the recipient to scan incoming transactions for their payments.

Announcing Frigate.
Frigate is an experimental Electrum server testing efficient Silent Payments scanning with ephemeral client keys.
Note that Frigate is currently a proof of concept for supporting Silent Payments on Electrum servers, and not a replacement for Electrs, Fulcrum etc.

It’s fine. There is a chance of address reuse if you hand out a change address to someone and they use it after the wallet has already used it for change.

I’m not aware of a published issue. But entropy quality is to some extent a scale, and there have been reports of funds lost from early hardware wallets that are difficult to explain by other means. I’d love to see more rigorous review of hardware wallet entropy.

2024-12-09 08:22:47 UTC

- reply

Glad you enjoyed it :)
I don’t agree with this absolute statement though - there are many factors in security. For example, it is entirely possible for a hardware wallet to have poorer entropy (for seed generation) than a software wallet, and it is in general harder to evaluate hardware wallets on this criterion.

Yes. It should already “just work” but this will make it work better.

Introducing Lark.
Lark is a Java port of HWI, a library used by many wallets to communicate over USB with with hardware wallets like @npub19ca…qj29 , Ledger, Trezor, @npub1tg7…cxmt and @npub1jg5…6n8n Jade.
HWI is a good example of the ‘single dependency’ situation in the famous xkcd comic. Until now, there has been no project like it.
However, with all the wealth stored on hardware wallets (especially those that can only communicate over USB) it's important to have multiple implementations. Lark represents the first complete reimplementation of all common USB HWW clients in a language other than Python.
Even though HWW manufacturers have used a dizzying array of different communication protocols and standards, Lark seeks to be identical to the HWI API, providing direct interchangeability and a more robust ecosystem.
All common commands are supported, and there is some additional functionality, such as retrieving a wallet registration from Ledger devices to avoid re-registration on every signing.
Lark is available as a command line application, and as a Java library for JVM-based applications. Hardware wallet manufacturers are invited to test their devices before it's integrated into Sparrow Wallet.
See https://github.com/sparrowwallet/larkapp for docs and binaries.

Creating a new wallet and selecting the different script type is the easiest approach. Note that Nested Segwit should be considered a legacy script type though - Native Segwit offers better privacy.

You can do this if you create the new account with a watch only keystore, but I haven’t seen a compelling reason to add this as a general feature.

Fwiw I don’t think any dependencies are required for BC UR if you limit the scope of data types. Not even CBOR is required if you just transmit txs and psbts.
Would like to see a clearer, technical explanation of why it’s so problematic to implement.

An alternative to Tor that has users stream sats to pay relays seems like an obvious next step in network level privacy tools. Streaming sats would greatly increase the costs of the DDOS-style attacks that affect Tor so much, and provide an incentive for relay operators.
