Engineered For Permanence

Built To
Last
Centuries.

While hardware wallets fail, software corrupts, and paper burns — your Vault Slate endures. Precision-machined from the same steel used in marine and medical-grade applications. No shortcuts. No compromises.

Marine-Grade Steel

Precision machined from 316L austenitic stainless steel — the same alloy used in surgical implants and deep-sea equipment. More corrosion-resistant than standard 304.

Material: ASTM A240 · 316L SS
Fire Resistant

Rated to 1,400°C — well beyond the 850°C peak of a typical house fire. Your seed phrase backup survives total loss events that destroy everything else.

Rating: 1400°C · 2552°F
Fully Waterproof

Rated to 100m submersion depth. Floods, burst pipes, ocean exposure — stainless steel is inherently impervious. No gaskets, no seals, nothing to degrade.

Submersion: 100m · IP68
Zero Electronics

No firmware. No batteries. No chips to be exploited. Your backup is pure physical form — legible in five hundred years without any technology.

Attack Surface: None
24-Word BIP39

24 engraved, clearly numbered slots compatible with every major BIP39 wallet — Bitcoin, Ethereum, Solana, and hundreds more. Store one or split across two slates for extra security.

Standard: BIP39 · BIP44 · SLIP44
Generational Storage

316L steel does not corrode under normal atmospheric conditions. A true inheritance-grade backup medium — your heirs can recover your wealth decades from now.
