Bitcoin wasn’t made for corporate balance sheets. It’s for splitting a bill, helping a friend, buying a coffee - peer to peer. Human to human. Yes, save some for the future. But don’t forget: it’s money. Spend & Replace. That's how Bitcoin will win.

🪺 Seed Phrase Hunt - Word 1 Wrapped in a shell. Holds a secret inside. You don’t hatch a plan without it.

This Easter weekend, we’re giving away $150 in Bitcoin and a Passport Core hardware wallet. Solve the riddles. Crack the seed. Win the stack. Here’s how it works 👇 💡 We’ll release 3 clues per day, from Friday to Monday on Twitter and Nostr. 🧩 Each clue reveals 1 word of a 12-word Bitcoin seed phrase, through riddles, puzzles, and rhymes. 📅 The clues reveal the seed words in order. No need to switch them around to find the valid seed. 🎯 Work out all 12 words → restore the wallet → drain the sats 💥 BONUS PRIZE – Passport Core → Be the first to comment the full 12-word seed phrase on this pinned post to win a Passport Core To qualify for the Passport Core, you also must repost this post. Help spread the hunt. 🐣 No forms. No catches. Just a bit of holiday fun, Bitcoin-style. We hope you enjoy the hunt and the long weekend.

Open-source + privacy = freedom. Last year, we open-sourced our Tor library. Now it's MIT licensed, free to use, modify, and build on. 🔗 Privacy matters. Open source powers the future. Who would you like to see integrate Tor into their wallet next, for full privacy? 🛠️ We wrote a blog post breaking down why this Tor library matters, what the MIT license change means for developers, and how easy it is to integrate. If you're building a privacy-first wallet, or know someone who is, this is for them.
