How to Spot Fake Tokens (Impersonation Coins) — The Name Can Match, but the Address Can't Lie

Anyone can create a token with the same name

On a blockchain, a token's name and ticker (symbol) are just strings the issuer writes freely. "USDT," "PEPE," the name of a famous project — you can mint a token with any of those names in about a minute. There is no trademark check and no duplicate-prevention. A token's true identity is one thing only: its contract address.

Patterns of impersonation

• Impersonating a famous coin — a new token is issued with the same name and logo as a top-market-cap coin, then promoted as "listed on a new chain."
• Riding a trend (same-name clones) — when a token goes viral, clones with the same name spring up in droves on other chains. The real one and the clone have exactly the same name and symbol, so they can't be told apart by name alone. Sometimes the clone turns out to be the rug pull; sometimes, conversely, the real one causes trouble and the clone is wrongly suspected.
• Fake listing events — fake token addresses are scattered along with phrases like "airdrop to celebrate listing on XX exchange."
• Exploiting bridge-address confusion — even for the same coin, the contract address differs per chain. Exploiting this confusion, scammers hand over a fake as "the Polygon-version address."

The habit of verifying the canonical address

• Copy from the official channel — use only the address from the project's official site or docs. Search results, Telegram promo posts, and addresses received by DM are not sources.
• Cross-check with aggregator sites — compare against the contract information on aggregator sites like CoinGecko. The address for each chain is listed individually.
• Compare the whole address — look-alike addresses that match only the first 4 and last 4 characters exist. Don't eyeball it; verify by copy-and-paste.

How CheckCrypto views impersonation

CheckCrypto maintains a list (registry) of verified canonical contracts. In the check, if a token using a famous symbol differs from the canonical address, a symbol-impersonation warning is attached, and a token that is not the canonical one does not receive the "normal by design" relief that stablecoins and wrapped tokens naturally get — because the standard is the address, not the name. The judging principle is published in the evaluation method.

What to remember

• Name, logo, and chart can be forged. Only the address is the identity.
• The same coin has a different address on a different chain — "which address on which chain" together forms one identity.
• Once the address is verified, the next step is the 5-minute pre-trade check.
