In today’s digital world, your seed phrase is everything. But paper can burn, phones can be hacked, and cloud storage? Risky.
That’s why we’re introducing a radically safer method to store your seed: a physically encoded metal card, using an offline, nearly indestructible technique based on the “1248 binary punch method.”
Inspired by old-world craftsmanship, this method uses no electronics, no software, and no servers.
Just a metal plate, a punch tool, and a smart way to encode your seed into a format that can’t be easily recognized — or stolen.
Why It Matters:
Invisible to the untrained eye: the seed is stored in a coded numeric format
Completely offline: no digital exposure
Durable and fire-resistant: stored on metal
Based on BIP39: fully compatible with modern crypto wallets
The “1248” technique allows you to convert seed words into numbers, then into patterns of marks on metal — and decode them only with the official BIP39 wordlist.
This method not only protects your funds, but also hides the very nature of the storage device — making it both secure and discreet.
