# How to identify counterfeit stablecoin tokens A token can copy a stablecoin’s name, symbol or artwork without being issued by that stablecoin’s issuer. Verify the exact chain and contract or mint against an official issuer registry, then inspect the actual transfer. A wallet’s dollar estimate, an unsolicited balance or a convincing screenshot does not authenticate the token. Evidence: [ERC-20 Token Standard](https://eips.ethereum.org/EIPS/eip-20); [USDC contract addresses](https://developers.circle.com/stablecoins/usdc-contract-addresses); [Ethereum security and scam prevention](https://ethereum.org/en/security/) Canonical: https://degreesofsatoshi.com/encyclopedia/counterfeit-stablecoins/ Published: 2026-10-02 Substantively modified: 2026-10-02 Independently verified by an automated reviewer: 2026-10-02T19:26:58.461Z Data current through: 2026-10-02 AI-assisted research and drafting with a separate automated source-verification pass; no external expert or named human review is implied. ## Key facts - **Names:** ERC-20 metadata does not make a token name or symbol globally unique. ([ERC-20 Token Standard](https://eips.ethereum.org/EIPS/eip-20)) - **Registry:** Circle publishes chain-specific USDC identities. ([USDC contract addresses](https://developers.circle.com/stablecoins/usdc-contract-addresses)) - **Action:** Unexpected tokens and links can be part of scams; receipt does not require interacting with them. ([Ethereum security and scam prevention](https://ethereum.org/en/security/)) ## Authenticate the asset before the amount Start from the issuer’s official website or documentation, not a link supplied by an unknown sender. Select the exact network and compare the token identifier. A token with a familiar ticker on a different contract is a different asset. For example, a wallet may display 10,000 units named USDC from an unrelated contract. The displayed quantity proves only what that contract reports, not a claim against Circle’s reserves.

Check the emitting token contract, destination and raw amount with the relevant decimal interpretation. A genuine transaction hash does not make every asset inside it genuine. Likewise, a wallet valuation can come from unreliable or irrelevant market data. Do not use that valuation as the basis for releasing goods, returning an overpayment or paying an unlock charge. Evidence: [ERC-20 Token Standard](https://eips.ethereum.org/EIPS/eip-20) ## Receiving a token is not a request you must fulfill An unsolicited token or NFT can contain a lure directing the reader to a website that asks for approval or a signature. Treat the advertised claim process as a new interaction requiring assessment, not a necessary step to remove the item. Use wallet display controls if you want to hide spam. Do not share recovery phrases or sign an approval merely because a token description says funds must be unlocked.

No. A verification label does not establish that a token belongs to the issuer named in its branding. Compare the exact chain and contract with the issuer’s official registry.
