A seed phrase can be used to restore access to your wallet and assets. It should not be photographed or stored in notes, cloud storage, email, or a password manager, as doing so creates a digital copy. A physical offline backup reduces the risk of remote theft caused by hacking, malware, or phishing.

Keystone Tablet Punch supports standard 12-, 18-, and 24-word recovery phrases. The layout of the three plates allows you to record one complete seed phrase of up to 24 words.

In the English BIP39 word list, the first four letters uniquely identify each word. For words that contain only three letters, all three letters are recorded. Before marking the plates, make sure the word order and every letter are correct.

Arrange the plates in numerical order, find the row for the required word, and locate the cells corresponding to its first four letters. Place the tip of the automatic center punch in the center of the correct cell and press down smoothly until a clear mark appears. Once finished, double-check every word and stack the plates in the correct order.

No. The included automatic center punch creates the mark using an internal spring mechanism. Avoid applying excessive pressure to prevent unnecessary strain on the spring.

The manufacturer states a fire-resistance threshold of 1399 to 1455 °C. For comparison, a typical house fire may reach approximately 649 °C. After any fire or other emergency, the condition of the backup should still be checked before use.

Yes. The plates are made entirely from 304 stainless steel, which is water-resistant and resistant to various types of corrosion. After contact with water, the plates should be cleaned, dried, and checked to make sure all markings remain clearly readable.

Yes. Keystone Tablet Punch has three holes of different diameters designed for padlock shackles. A padlock helps keep the plates together and adds an extra physical barrier, but it does not replace secure storage. A padlock is not included.

Store the backup in a dry, secure location that can only be accessed by you or someone you fully trust. Do not keep Keystone Tablet Punch next to your hardware wallet, and never publish photos of the plates. For additional redundancy, you can keep a separate backup in another secure location.

No. Keystone Tablet Punch does not store private keys electronically and cannot sign transactions. It is a physical backup of your seed phrase that complements a hardware or software wallet and can be used to restore access.

If someone else may have gained access to your seed phrase, create a new wallet with a new recovery phrase as soon as possible and transfer all assets to it. Do not reuse a compromised seed phrase. An additional passphrase can reduce the risk, but it should be stored separately from the main recovery phrase.

Keystone Tablet Punch is compatible with hardware and software wallets that generate standard 12-, 18-, or 24-word BIP39 seed phrases. These include Keystone, Ledger, Trezor, SafePal, OneKey, Coldcard, and many other compatible wallets. Before marking the plates, check the recovery phrase format used by your specific wallet.

BIP39 is an open standard used to create mnemonic phrases for cryptocurrency wallets. The English BIP39 word list contains 2048 words, and the first four letters of each word are unique. You can view the full list here.
