Penlock: Offline Tool to Generate, Split, and Recover Seed Phrases

Discover Penlock, the paper-based tool to generate seed phrases, split them into 2-of-3 backups, and recover them offline using proven cryptography.

Also, check out their metal backup — it's definitely one of the best 24-word metal backups on the market! You can store your Penlock shares on it by using an electric engraver instead of stamping. Can't wait for a 12-word version that's fully Penlock compatible! There's also a shipping option in South Korea, thanks to @Coconut. : https://store.btcmap.kr/stores/powbitcoiner/ Meanwhile, we're busy setting up our own Geyser shop, where you'll find kits in bulk (packs of 10 and 50), as well as private support, consulting, and more!

We're excited to welcome our second sponsor: @Coconut. ! 🥥 The @Coconut. team is building two mobile apps that work in tandem: Coconut Wallet, a watch-only Bitcoin wallet, and Coconut Vault, an offline signing app designed to run on fully isolated devices. Beyond software, they operate the recently opened Bitcoin Center Seoul to support education and community development 👥. We first connected at a Bitcoin public event in a Korean university, where their CEO took the stage as the MC. The vibe of a nearly-full amphitheater studying the potential of Bitcoin was really something else! ✨ You can find them at

We're thrilled to announce our first sponsor: Angor! 🎉 @Angor is a P2P crowdfunding protocol built on Bitcoin and Nostr⚡. It leverages smart contracts to provide a fully non-custodial solution, using Nostr as its only back-end. We've been in touch with the @Angor team since Penlock's pre-release in Bali. In fact, the not-for-profit Penlock shop was largely inspired by our conversations about aligning incentives between open-source projects and their backers. The team has a great "build forward" mindset and has consistently supported the community, so we're really glad to feature them on our kits! 🤝 You can find them at https://angor.io. A V2 is coming soon—we definitely advise checking that one out! 👀 #bitcoin #penlock #angor

🚀 We're seeking to raise 0.04 BTC to bootstrap a not-for-profit Penlock shop! 🎯 Our goal: fund free Penlock kits & workshops at Bitcoin conferences worldwide! ✨ Backers can get: • Private support • Consulting sessions • Their brand on the kits! Join us to celebrate self-custody and self-sovereignty through this peer-to-peer campaign on @Angor 🔁 Repost to make Penlock grow. 🥰 https://hub.angor.io/project/angor1qfydf802v2efvxufevrfg0mvtlrxln63rkzmdxw
