You can't remove a token from the blockchain, but depending on the token's contract and your wallet, you may still be able to deal with it:
- Hide the token in your wallet so it stops appearing in your balance view.
- Transfer it to another address — though this depends on what the token contract allows. Some malicious tokens block transfers (honeypots), so this isn't always possible.
Managing how tokens display in your wallet is handled by the wallet itself, not by STON.fi. For instructions specific to your wallet, contact that wallet's support team.
If it's a scam, report it via the Submit a request form.
