I have reported this as a phishing app to @Apple through their trademark dept, since they seem to ignore normal app reports. Their reply: “Apple encourages the parties to a dispute to work directly with one another”. It appears they either can’t or won’t act immediately.

By far the most relevant issue affecting Bitcoin today👇

1/🧡 The board of the @_einundzwanzig_ Bitcoin Association proudly supports @SparrowWallet with a 2.1 million sat donation! 🎉 Why? Because Sparrow is one of the best tools for sovereign Bitcoin usage. Here’s why we back this project—and why you should too. 🧵👇

Consolidating UTXOs into a single tx during wallet migration? 🚫 Staggered broadcasts and privacy-preserving wallet migration. ✅ @nvk, @Rob1Ham & @craigraw advocate for "Broadcast Pool" in @bitcoincoreorg , enabling future-dated txs for greater privacy & control. [BR089]

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 @SparrowWallet. See https://t.co/JDbH4fzlvQ for docs and binaries.

All common commands are already supported, and there is some additional functionality, such as retrieving a wallet registration from Ledger devices to avoid re-registration on every signing.

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.

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.

HWI is a good example of the situation described in this famous @xkcd comic. Until now, there has been no project like it. My personal thanks to @achow101 for building and maintaining it, in addition to all your other responsibilities. Thank you Ava.

Introducing Lark. Lark is a Java port of HWI, a library used by many wallets to communicate over USB with with hardware wallets like @Coldcardwallet, @Ledger, @Trezor, @BitBoxSwiss and @BlockstreamJade.

2. Broadcasts can be future-dated, meaning the transactions will only be submitted to the mempool after a delay. This is particularly useful for privacy, for example in migrating UTXOs separately from one wallet to another without broadcasting all the transactions at once.

1. Wallets can retrieve previously broadcasted transactions regardless of mempool fee conditions, while still respecting RBF rules. Without this, rising fee rates can cause a broadcasted transaction to be evicted from the mempool, making it harder to find and fee bump.

Broadcast pool is a proposed feature for Bitcoin Core which would allow a node to keep a separate record of transactions sent directly to it from a wallet for broadcasting. This provides two key benefits 🧵

We need this Bitcoin Core feature https://t.co/8VHkEy0i4g My motivation is helping people migrate wallets without consolidating UTXOs and without doxing with timing analysis. It's very simple and useful. @bitcoinoptech @HRF

Craig Raw | How You Can (Still) Transact Privately with Bitcoin 🔒@craigraw of @SparrowWallet explains Bitcoin’s UTXO model and privacy techniques like CoinJoin, PayJoin, and CoinSwap. He emphasizes avoiding address reuse and the importance of coordination in privacy services.

HRF is excited to announce the CISA Research Fellowship 🎉 Cross-Input Signature Aggregation (CISA) is a proposed upgrade to Bitcoin that could potentially enhance privacy and provide cost-savings for transactions HRF is sponsoring a four-month research fellowship to help

Whatever the proposal, I will continue to evaluate it on the key principles of self sovereignty. Without them, I believe we will simply end up in another fractional reserve, fiat world.
