Methodology for 4-Letter Symbol Creation

Symbol generating algorithm

The symbol must consist of exactly four alphabetic characters (A–Z).
Avoid using special characters, numbers, or spaces.
The symbol must be unique within the system.
Symbols should be intuitive and easily associated with the company or digital asset name.

First Two Characters (Prefix Rule):

Take the first two characters from the company name, ensuring they are alphabetic. If the company name begins with a number or special character, skip it and move to the first two valid alphabetic characters.
If the company name consists of more than one word, take the first character from each of the first two words.

Examples:

Third Character (Modifier Rule):

Use the first vowel (A, E, I, O, U) following the prefix letters. If no vowel is present within the name, use the next available consonant.
In cases where the vowel rule results in duplication of existing symbols, revert to the next available consonant or use the first character of the second or third word.

Examples:

Fourth Character (Finalizer Rule):

The fourth character is used to differentiate symbols further if the first three characters are already in use.
If a conflict arises or if the symbol is already in use, use the next available consonant from the name or use the first letter of the third word (if present).
If no unique combination is available, the final character should be incremented alphabetically (A, B, C, etc.) to avoid conflicts.

Examples:

Addepar → ADR (Next consonant is "R" after "AD")
Biofourmis → BIOF (Second word starts with "F")
ABL Space Systems → ASSY (In case of conflict, use additional characters from the second/third word)

If a company name includes non-alphabetic characters, they should be ignored when generating the symbol.
For company names consisting of multiple words, the first letter of each of the first two words is used, followed by rules for vowels and consonants.
Ensure no duplication of symbols; if a symbol is already in use, modify the final character to create uniqueness, either by using a letter from the second or third word or by incrementing alphabetically.

For digital assets, similar rules apply, but prioritize well-known abbreviations or common industry terms related to the asset. If no standard abbreviation exists, follow the same company name rules.
When creating symbols for tokens or cryptocurrencies, the use of common industry terms such as "BTC," "ETH," etc., may be applied for better recognition.

Before finalizing a symbol, cross-check it against the existing symbols database to ensure uniqueness.
If a conflict arises, modify the final character or increment alphabetically (e.g., if "BIOF" is taken, it could become "BIOG").
