FIELD OF INVENTION

The present invention relates to a device and method for storing a seed phrase, and more particularly, the present invention relates to a device and method for backing up a seed phrase that allows access to a cryptocurrency wallet.

BACKGROUND

Crypto wallet, also known as a cryptocurrency wallet, stores cryptographic keys that track the ownership and transactions in cryptocurrency. Most of the known Crypto wallets are secured through cryptographic keys, wherein the wallets can generate a seed phrase, seed recovery phrase, or backup seed phrase to recover the key associated with the wallet. The seed phrase includes a list of words through which the wallet can create all the public and private keys. The wallet generates the recovery seed phrase for the user's record. The seed phrase is like a key to the wallet and must be safely stored by a user. When the user installs the wallet again, the seed phrase is needed for gaining access to the cryptocurrency.

Thus, safe, and secure storage of the seed phrase is important. Users generally write the seed phrase on paper which can be easily lost or spoiled. Similarly, storing the seed phrase on electronic memory, such as computer memory or removable storage may not be safe because of risks of hacking or hardware failure. Many people lost their hard-earned money in the form of cryptocurrency because they forgot the password or loses the seed phrase. Thus, considering the rise in popularity of the cryptocurrency, a desire is there for a safe and secure back-up of the seed phrase.

Disclosed is a device for safely and securely storing a seed phrase of a crypto wallet or like cryptographic services. Currently, the known crypto wallets produce the seed phrase having about 12-24 words, however, any number of words are within the scope of the present invention. The disclosed device is compact that can be easily concealed and securely stored. Moreover, the device does not degenerate with time, is fireproof and corrosion resistant.

Referring to FIG. 1, which shows an exemplary embodiment of the disclosed device. The device 100 can have two cover plates that sandwich several grid plates. FIG. 1 shows a front cover plate 110 and a rear cover plate 120. Two grid plates i.e., the first grid plate 130 and the second grid plate 140 are sandwiched between the front cover plate 110 and the rear cover plate 120. The cover plates and the grid plated are bound together using a fastener 150, such as each plate can swivel relative to the other plates. Each cover plate and the grid plate are having at least two holes at corners, wherein one hole is for the fastener. The other hole can be used to secure the plates, such as using a lock or another fastener to secure the grid plates and the data encoded on the grid plates. FIG. 1 shows four holes 160 at the four corners, wherein the top-left corner is having a post screw swively binding the four plates. All the four holes can be fastened using the post screws securing the grid plates between the cover plates. Alternatively, at least two locks can be provided at opposite corners for securing the grid plates. The locks can be key lock, combination lock, and like locks known to a skilled person.

Each plate of the device can be made of a metal, such as stainless steel or titanium that is of high-strength and corrosion-resistant. The data encoded on the disclosed grid plates made of metal becomes permanent and perpetual. Any metal or alloy that is both of high strength and corrosion-resistant can be used without departing from the scope of the present invention. The two cover plates i.e., the front plate and the rear plate protect the inner grid plates which have the encoded seed phrase.

Referring to FIG. 2-5 which shows both sides of the inner grid plates. FIG. 2 shows the front face 132 of the first grid plate 130. The grid plate is having a grid pattern that includes the rows and columns. The grid having a column header 136 and a row header 138. The grid pattern is based on a type of wordlist used for generating the seed phrase. For example, FIG. 2 shows the grid pattern for a standard BIP39 wordlist. A skilled person will understand that a different wordlist can be used for generating the seed phrase, and all such wordlists are within the scope of the present invention. The disclosed device can be modified according to the type of wordlist/algorithm used for generating the seed phrase. Moreover, one or more grid plates can be provided based on the number of words in the seed phrase. FIGS. 2-5 shows the grid plates for a seed phrase having 12-24 words.

Each column in the grid represents a word/BIP39 number in order. The front face 132 is having six columns for six words in order. The rear face 134, shown in FIG. 3, is also having six columns for the next six words in order. The front face 142 of the second grid plate 140, shown in FIG. 4, is having six columns for the next six words in order. Lastly, the rear face 144 of the second grid plate 140 is having six columns for the last six words in order i.e., words 19 to 24 in the list of words. Each column has four sub-columns for a four-digit BIP39 number. Each sub-column has ten rows that represent the number 0-9. The surface of the grid plate can be punched with a punch tool, for example, a cell of the grid can be punched to encode the data. The cell herein refers to an intersection of a column and row of the grid.

In one aspect, disclosed is a kit and method of use thereof. The kit can include the above device 100, a punch tool, template sheets, and a BIP39 word list. The punch tool can be a pen-shaped tool having a sharp pointer. The pointer of the punch tool can be pressed against the surface of the grid plate, cutting away a thin layer of metal, creating a grove. The sharp pointer can create a contrasting grove in a cell of the grid.

An exemplary embodiment of the template sheet is shown in FIG. 5. Such a sheet can be optional but provide convenience in backing-up the seed phrase. Shown is the template sheet for 12 words seed phrases. Two such sheets can be provided each having six consecutive rows. Each row starts with a numeral, which is the order of the word in the seed phrase. This numeral in the row of the template sheet also corresponds to a numeral in the column header of the grid. A first word of the seed phrase can be written in-order in the first column of the row. Thereafter the corresponding BIP39 number for each word can be found from the standard BIP39 word list. Such a BIP39 wordlist is available and distributed unchanged in the standard format. Thereafter, the corresponding BIP39 number can be written against each word. A BIP39 number is a four-digit unique number for each word in the word list.

Also, disclosed is a kit and method of use thereof in encoding the seed phrase on the disclosed device. First, the seed phrase can be generated, from a standard word list or algorithm. The seed phrase can optionally be verified to ensure that the words are correct. The words can be written on the provided template sheets, as shown in FIG. 6. The words should be written in the same order as in the seed phrase if the order is important. Thereafter, the numeric code of each word can be looked into the standard word list. For example, the words based on the BIP39 standard list can be looked onto the list for the four-digit code. The code can be written against each word in the row against the corresponding word, also shown in FIG. 6. The words can now be encoded on the grid plates of the device. Each column in the grid represents a word and the sub-columns can be used to record the numeric code associated with the word. Each cell in the column represents a number. Optionally, first, the numbers can be marked on the grid plated using a pointed pen/marker and the marks can then be punched. It minimizes the chances of error in punching the correct cell. However, such as step is optional, and the cells can be punched directly. FIG. 7 shows the first word “ALIEN” in the template list (shown in FIG. 6) encoded on the first column “1” of the grid. The code associated with the word “ALIEN” is “0051”. Digits 0, 0, 5, and 1 are marked in related rows as shown in FIG. 7. The numbering of the column in the header i.e., 1, 2, 3 . . . , n is the order of the words in the seed phrase. Ten rows represent numerals 0-9, which can be used to represent digits in the numeral code. The number of sub-columns can be increased or decreased depending upon the numerals in the code. Finally, using the punch tool, each cell can be punched to form a permanent groove. The grid plates can then be closed and optionally secured. For example, additional screws or locks can be fastened to other holes of the device.

It is to be understood that the Figures show a device and method for encoding a seed phrase related to a cryptocurrency, however, any information that can be represented in numeral codes can be encoded on the disclosed device. Also, the device can be modified for encoding alphanumeric codes, such as passwords. Additionally, the plates can be separated and stored separately, so that the complete seed phare cannot be stolen. Additional cover plates and rivets can be provided in the kit for storing the grid plates separately. Also, FIG. 1 shows four holes, the number of holes can be varied without departing from the scope of the present invention.

Referring to FIG. 8 which shows an exploded view of the device. The device having two grid plates covered by two cover plates. Each having four holes at the four corners. After encoding the information on the grid plates, the grid plates can be secured using the fasteners. FIG. 8 shows four post screws securing the four corners. It is to be noted that the grid and the grid headers are engraved in the metal plates to protect from loss of information during fire, water, or other damage. Also, it is to be understood that the disclosed device can be used to store confidential information, such as pin and passwords. The row headers and the column headers can have alphabets, numerals, symbols, and like depending upon the information to be encoded.

While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein.
