Titanium Seed Storage Plate are made using a particular technique, which involves the use of advanced technology.

The 4-letter secret of the mnemonic board is revealed
If you are new to the mnemonic board, you may be confused as to why it only gives 4 letter positions. In fact, there are several key reasons behind this.
Types of mnemonics
First, mnemonics are usually divided into 12, 18, and 24. Most software wallets generate 12 mnemonics, while hardware wallets generate 24. Mnemonics are the core of asset management, and whoever owns the mnemonic is the real owner of the account.
The importance of the first four mnemonics
The first four digits of each mnemonic are unique, which is why the mnemonic board only gives 4 empty positions. This means that even if you lose the rest, as long as you remember the first four digits, you can still get your account back.
Limited number of mnemonics
According to the BIP-39 standard, the total number of mnemonics is limited, with a total of only 2048. Each word corresponds to a unique number.

Tips for entering mnemonics
Some wallet software only needs to enter 3 or 4 letters when importing an account, and several word options will appear. Among these options, there must be the word you need to enter.
Different wallet addresses
The same set of mnemonics is imported into different wallets, and the Ethereum address obtained is usually the same, but the Bitcoin address may be different. For example, if the mnemonics generated by the Ledger wallet are imported into the OKX WEB3 wallet, the original Bitcoin assets may not appear directly in the OKX wallet because the export rules are different.
Passphrase function
Hardware wallets usually have a Passphrase function, that is, in addition to the 24 mnemonics, you can customize a mnemonic, which will generate a completely different account. Even if others know your 24 mnemonics and your Passphrase, they cannot obtain your assets.
Protect your mnemonics
Finally, I remind you again that you must not tell others your mnemonics casually. Whoever owns the mnemonic has the management authority of this account.
I hope this information can help you better understand the design principles and usage tips of the mnemonic board.

Products Parameter

Titanium single/double sided Titanium Seed Storage Plate

Can record 1-12/13-24 mnemonic words
Specification: 85*54*2 mm with the size of the certificate card
Process: single side, double side etching process
Packing: independent sealed bag packing

Products Process

Metal plate engraving method

Metal stamping with letters + hammering (recommended).

Recommended specifications for metal stamping: 4mm in height, hammer >1kg

Advantages: easy to use, great force works wonders

Effect of electrolytic engraving

Disadvantages: The cost of metal stamping hammer is relatively high, and the metal plate will be slightly deformed when it is struck. Suitable for engraving multiple metal plates

Salt water electrolytic etching (recommended)

Advantages: cheap and cost-effective

Disadvantages: need to learn the principles and operation methods, and the engraving time is relatively long (about 30 minutes)

Engraving with engraving pen (not recommended)

Advantages: simple to use

Disadvantages: high cost, easy drift and flowering of the pen, shallow engraving, and high noise

Electro-etching is a processing technology that uses electrolytic reaction to complete metal etching. In the salt water solution, the metal plate is used as the anode (transparent glue protection is required and hollowed-out characters are processed), and copper is used as the auxiliary cathode. When the power is turned on, an electrochemical reaction occurs on the metal surface, dissolving and removing part of the metal, thereby achieving the purpose of metal etching.

Products Technology

1. Melting: The titanium alloy is melted in a vacuum or inert gas chamber to prevent contamination.

2. Casting: The melted titanium alloy is then cast into a mold using a technique called investment casting.

3. Rolling: The annealed titanium structure is then rolled into thin sheets using specialized equipment.

4. Etching: The rolled titanium sheets are etched with a specialized acid to remove any impurities and prepare them for further processing.

5. Cutting: The titanium sheets are then cut into seed plate shapes by a specialized machine.

6. Polishing: The seed plates are polished to remove any scratches and prepare them for final use.

Products Advantage

1. High Strength: Titanium seed plates are made from titanium alloys, which have high strength-to-weight ratios. This property makes them ideal for producing thin and lightweight electronic components.
2. High Purity: Titanium seed plates can be produced with high purity levels, which are essential for producing high-quality electronic components.
3. Corrosion Resistance: Titanium seed plates are highly resistant to corrosion, which makes them ideal for use in harsh environments.
4. Biocompatibility: Titanium seed plates are biocompatible, which makes them ideal for use in medical applications such as orthopedic implants.
