Your eyes, not a promise

Diff

Compare two addresses

Put the checksum in one note and the stranger's address in another. Diff them. Do not squint at a screenshot.

Checking is not a guarantee. A match tells you the bytes are the ones published here. It does not tell you a trade will make money.

1. 1 Paste both as plain text

   Screenshots hide a character inside the image compression. Text does not.

2. 2 Lowercase both

   Then you are comparing bytes, not typography.

3. 3 Walk until one differs

   The first difference ends the check. You do not need a score.

4. 4 Keep the winner only if it matches this site

   A pretty match between two strangers is still two strangers.
