Strategy 01
Redundant single-sig
Engrave the same 24 words on all three plates. Store them in three separate locations — home, family, bank box. Lose one plate (or two), recover from the third.
Yokis
Write your seed phrase like a pen. Store it like a vault.
Three black-anodized 304 stainless steel plates and a pocket engraver that etches each word like ink. No stamps, no punches, no hammers — just a hand movement and a line of steel that outlives the paper it replaced.

Three plates. Three ways to use them.
Pick the backup strategy that matches your threat model.
Strategy 02
Split backup
Shard a single seed across the plates (Shamir, or a simple split you trust). No single plate recovers the wallet on its own — attackers need two, you need two.
Strategy 03
Multisig cosigners
Running a 2-of-3 multisig? One plate per cosigner key. A dedicated piece of steel for every share of the wallet, out of the box.
How Yokis works
-
01
Generate offline
Generate a BIP39 seed on your hardware wallet. Keep the session airgapped. Don't photograph the words.
-
02
Write with the engraver
Charge the detachable battery with any USB-C cable. Click the pen on, write each word on its numbered row — feels like a ballpoint, cuts like steel.
-
03
Store geographically
Put each plate somewhere different. Home, family, vault. Plates survive fire, water, and decades of time without a power source.
Need more plates?
Extra plate pack — €29
Three more black-anodized plates. Same steel, same size, no engraver — use them to expand a multisig, hand a spare to a new cosigner, or add a deeper layer of redundancy.
