KEYSTONE Crypto Seed Storage Tablet – Durable 304 Steel Backed Seed Phrase Backup, Wallet Compatibility

Secure, portable seed phrase backup you can trust

The KEYSTONE Tablet is a compact, wallet‑friendly steel capsule designed to protect your crypto seed phrase over the long term. Built from grade 304 stainless steel, it resists corrosion and is engineered with multiple screws to help prevent deformation. The design also carries a high fire‑resistance threshold, tested from 1399 to 1455°C (2550 to 2651°F), offering a practical safeguard in the event of a house fire. This combination of durability and thoughtful protection creates a reliable physical backup you can store with confidence.

Designed with everyday use in mind, the Keystone Tablet is just a bit larger than a credit card, making it easy to tuck into a bag, a safe, or a desk drawer. A sliding mechanism provides quick access to your seed letters, while a built‑in keyhole supports an optional physical lock for additional peace of mind. The letters are laser engraved and shielded with anti‑tampering stickers, ensuring they stay legible and intact even with routine handling.

Seed phrase compatibility and practical use

This device supports 12, 18, or 24 word seed phrases (only the first four letters of each word are needed) and is compatible with all BIP39 wallets and software wallets. Whether you use hardware wallets like Ledger, Trezor, or KeepKey, or software wallets, this capsule is designed to accommodate a broad ecosystem of crypto tools. The kit includes a complete set of alphabet tiles, extra screws, a screwdriver, anti‑tampering stickers, and a concise guide to help you assemble and store securely.
