Shipping detailsInside your kit
Two cards that work together. An engraving pen that makes each word permanent. A physical backup you create yourself.
Designed with purpose
Paper can burn, soak through, or fade. Crypto Seed Bank® puts your backup into 304 grade stainless steel, with lettering physically engraved into the surface.
No account. No subscription. Your backup. Your control.
Before you start
The cards have space for up to 24 recovery words and support the English BIP39 word list used by many hardware and software wallets. Check your wallet’s recovery format before you start.
No specialist experience is required, but engraving takes patience. The stencils help you form each letter. Watch the guide, use a stable surface, and take breaks when needed.
Allow around 30 minutes per card as a starting point. Your pace and phrase length will affect the time. Accuracy matters more than speed, so check every word and its position.
For two separate backups, engrave the complete phrase on each card and store them in different secure locations. You can instead close the engraved faces inward and seal the pair together, as shown in the tour, but then both copies share one storage location. The seals show signs of opening; they are not a lock. Anyone who can read your recovery phrase may be able to access your wallet.
The engraving pen has a sharp tip. Read the instructions carefully, use a stable work surface, and keep the kit away from children.
