Just caught up on something interesting that Jack Dorsey's Block has been pushing lately. They dropped the Bitkey wallet earlier this year and it's actually pretty different from what we usually see in hardware wallets.

The thing that stands out is the touchscreen design combined with a 2-of-3 multi-sig setup. No seed phrases to worry about, which honestly makes it more user-friendly than most hardware wallets out there. They also baked in inheritance planning, which is a smart move for long-term Bitcoin holders thinking about what happens to their stash.

But it's not just the wallet that's catching attention. Block has been making some real moves with Cash App too. They added this feature where payments you receive from friends automatically convert to Bitcoin, and you get 5% cashback when you spend at Square merchants. The withdrawal limits went up to 10k per day and 25k per week, which gives people more flexibility.

What's particularly notable is how Block is pushing Bitcoin adoption at the merchant level. Square merchants can now accept Bitcoin payments via NFC tap, with settlement happening almost instantly through Lightning Network. They're waiving processing fees until 2026, which is a pretty aggressive move to get adoption.

Block also released their proof-of-reserve showing Bitcoin holdings across Cash App, Square, and their treasury at around 2.2 billion. You can verify it yourself through on-chain signatures, which is the kind of transparency more companies should be doing.

Overall, Jack Dorsey's Block is clearly betting big on Bitcoin infrastructure. Whether it's through Bitkey hardware wallets or integrating Bitcoin payments into Cash App and Square, they're building out a pretty comprehensive stack. Interesting to watch how this plays out against other players in the space.
