When working with the Ronin Wallet, ensuring that you're validating addresses correctly is essential. Recently, I came across a situation where a regex pattern seemed straightforward but failed to match the expected string format.

Understanding the Issue The initial regex pattern intended to recognize wallet addresses had a small but significant oversight. Here is the example of the wallet address that should be matched: [[See Video to Reveal this Text or Code Snippet]] The challenge was that the regex pattern created to search for this string did not identify it correctly: [[See Video to Reveal this Text or Code Snippet]] The issue lies in the misunderstanding of the number of characters that follow the prefix ronin:. Upon further investigation, it became clear that this string pattern allows only 40 characters following ronin:. With that in mind, let's break down how to correct the regex. Breaking Down the Solution Identifying the Mistake The Count: The original pattern specified {46} which incorrectly suggested that 46 characters should follow. However, Ronin wallet addresses consist of 40 hexadecimal characters. Character Set: The character set [a-fA-F0-9] correctly identifies valid characters (hexadecimal), so that part of the regex is accurate. Implementing the Fix To rectify the pattern, we need to modify it from: [[See Video to Reveal this Text or Code Snippet]] to: [[See Video to Reveal this Text or Code Snippet]] Updated Code Example Here’s how your updated Swift code should look: [[See Video to Reveal this Text or Code Snippet]] Testing the Regex After making this change, ensure that you run tests with various potential Ronin wallet addresses, both valid and invalid, to confirm that your regex works as expected.

By simply adjusting the character count from 46 to 40, we now have a robust pattern that accurately identifies valid addresses.
