UKey Seed Ti Quick Guide

UKey Seed Ti utilizes a high-strength titanium plate to record seed phrase indexes and employs a proprietary UKEY Serial Number to secure the correct sequence. Each word is represented by its standard index position from the official 2048 wordlist, with values ranging from 0 to 2047.

I. Core Concepts

To correctly use the UKey Seed Ti, please understand the following three core data elements:

  • UKEY Serial Number

    • Standard Format: UKEY-XXXX-XXXX-XXXX-XXXX

    • Function: Used exclusively to securely store the sequence of the seed phrase. It absolutely does not contain any plaintext content of the seed phrase itself.

  • Index Number

    • Function: Represents the code for the specific word.

    • Format Specification: Ranges from 0-2047. It is recommended to write it in a 4-digit decimal format on the titanium plate (e.g., 0017 refers to index 17 in the wordlist, which corresponds to the 18th word).

  • Sequence Number

    • Function: Represents the correct position of the word after recovery.

    • Logic: Uses 1-based positional semantics. It indicates which index item should be extracted from the current list during the reorganization process.

II. Asset Recovery Process

When you need to restore your wallet account, please follow these standardized steps:

  1. Prepare Data: Retrieve all the 4-digit Index Numbers recorded on your UKey Seed Ti titanium plate.

  2. Input Serial Number: Enter the corresponding UKEY Serial Number into a secure recovery tool or device.

  3. Obtain Sequence: Decode the serial number to output the correct list of Sequence Numbers.

  4. Rearrange Indexes: Reorder the list of Index Numbers recorded on the titanium plate according to the decoded Sequence Numbers.

  5. Retrieve Words: Use the official 2048 wordlist of the same language used during backup to convert the rearranged Index Numbers back into plaintext seed words one by one.

III. Sequencing and Recovery Example

Here is an example demonstrating a micro-recovery process for 3 seed words:

  • Current Indexes on Titanium Plate (Unordered): 0017, 1203, 0042

  • Sequence Decoded from Serial Number: 3, 1, 2

  • Rearranged Result Based on Sequence: 0042, 0017, 1203 (You can then reference the wordlist to obtain the correct plaintext words).

IV. Important Notices & Security Recommendations

  • Dual Verification: The Index Numbers (representing the words) and the UKEY Serial Number (representing the order) are mutually dependent. Both are strictly required for recovery.

  • Wordlist Consistency: When converting indexes back to words, you must use the official 2048 wordlist in the exact same language as your original backup.

  • Quantity Match: The total number of recorded indexes on the titanium plate must strictly match the word count supported by the UKEY Serial Number.

  • Physical Security: Never store your complete seed phrase in plaintext in any network-connected environment (e.g., digital notes, cloud storage, messaging apps). We strongly recommend storing your titanium plate and the serial number securely in separate physical locations.
