What we make
Generate keys with your own entropy and back them up so they can be recovered. Dice, seed cards, tamper-evident bags, and a setup path that works with SeedSigner and any BIP-39 wallet.
Air-gapped signing device. You create the keys. The device never holds them. Standard and Premium, assembled or DIY.
Permanent metal backups and the consumables you run out of. SteelQR plates, center punch, and refill packs for seed cards, envelopes, and dice.
A forensic examination of Bitcoin's governance crisis and the path to implementation diversity that makes the network actually secure. For builders, researchers, and anyone paying attention.
Why OwnandKeep
Bitcoin self-custody is one of the most important financial decisions a person can make. The tools to do it well exist. The knowledge to use them confidently is harder to find. OwnandKeep curates both.
We sell hardware kits on Amazon and eBay because that is where people shop. We write books because sovereignty without understanding is fragile. We build software because what exists is not good enough yet.
Be independent. Be prepared. Own and keep.
