Compare Crypto Wallet Addresses — Codepoint Diff
Verify that two wallet addresses are truly identical at the Unicode codepoint level — not just visually similar. A single Cyrillic "о" substituted for Latin "o" looks identical but sends funds to a different address.
Crypto wallet address scams increasingly use homoglyph substitution rather than simple typos. A scammer generates an address where the first and last 4–6 characters match the victim's real address, then substitutes 1–2 characters in the middle with Cyrillic lookalikes. The victim copy-pastes the address from a chat message or support ticket, the font renders both identically, and the funds go to the scammer.
How address-swapping scams work
- Clipboard hijacking: Malware monitors the clipboard for wallet-address patterns and replaces them on paste. Compare the address from your trusted source with what was actually pasted.
- Chat message injection: Support scammers or Discord bots post an "updated" address that looks like the original but contains Cyrillic substitutions in the middle characters.
- Fake transaction confirmations: Phishing emails include a lookalike address in the "send to" field that passes a visual check.
How to compare wallet addresses
- Open the Homoglyph Detector and click the Compare two strings tab.
- Paste your trusted wallet address (from your own wallet software or a verified source) into String A. Paste the address you received (from email, chat, or clipboard) into String B.
- Click Compare. If any codepoints differ — even if the characters look identical — the tool lists each position with the exact codepoints from both strings. Do not send funds if any differences are found.
Security recommendation
For high-value transfers, always verify wallet addresses through multiple channels: (1) codepoint-level comparison using this tool, (2) QR code scan directly from the recipient's wallet, (3) confirmation via a separate communication channel (phone or video call — not email or chat).
