Seed Keys now offers Penlock, a paper-based Bitcoin security tool. Single kits are available for immediate purchase.
Penlock helps you generate a 12-word seed phrase offline. It also splits the seed into a 2-of-3 backup. You can recover the full seed using any two shares.
If you enjoy DIY projects and prefer to handle security yourself, this is a great tool.
Key features include compatibility with the BIP39 word list and proven cryptography. The manual process requires no electronics, which protects against remote hacking. Integrated error correction helps prevent mistakes. You can also distribute shares for trust-minimized inheritance.
Penlock is an open-source project. Documentation is publicly available on GitHub for independent verification.
Penlock shares integrate well with metal seed phrase storage. You can save your shares on Seed Keys metal devices, providing long-lasting protection for your Bitcoin.
Customers may purchase kits individually by unit. Penlock typically sells products in packs of ten. Seed Keys provides a single-unit option.
