Built to outlast your hardware wallet.

Rust-resistant and sealed against moisture. Bury it, submerge it, forget it for a decade.
Offline by design
No electronics, no firmware, no attack surface. Just your words, punched into steel by your hand.

Designed to remain readable a hundred years from now, so your heirs can still recover the coins.
Yokis
One plate. One job. A lifetime of steel.
