Ever found a random token in your Binance.US Wallet that you never bought or earned? You've been spammed. In the open world of blockchain, anyone can send tokens to anyone else, and scammers exploit that freedom. Here's what you need to know.
What are spam tokens?
Spam tokens are unsolicited tokens airdropped to thousands of wallets at once. They're designed to look official or valuable, but they're not. Their goal is to trick you into interacting with them, which can open the door to losing your funds.
How to spot a spam token
You didn't buy it, trade for it, or earn it. If a token appeared out of nowhere, it's probably spam.
The name looks suspicious. Tokens with names like "USDT2," "FreeETH," or "BonusAirdrop" are red flags. Some impersonate popular tokens like BNB or USDT. Their icons are often missing or look off because they lack proper metadata.
It claims to be worth a lot, but you can't sell it. Spam tokens often display an inflated value until you try to cash out.
The on-chain data looks off. Lots of transfers but very few holders is a strong sign something's wrong. Legitimate tokens typically have many holders.
The smart contract is unverified or hidden. Scammers hide their code because they don't want you to see what it does.
What do scammers want?
Scammers aren't filling your wallet for fun. Here's how they operate:
Distract. Cluttering your wallet with random tokens can cause confusion during trades. Imagine trying to swap stablecoins for ETH and accidentally selecting a fake ETH token instead. One small slip, and your real funds are gone.
Entice. Some scammers add liquidity to spam tokens to make them look valuable, hoping you'll buy in. Once you do, you often can't sell.
Trick. Some spam tokens include messages like "Claim your prize!" or embed phishing links in their token names. These links lead to fake websites designed to steal your wallet credentials or seed phrase.
Steal. Interacting with a spam token can trigger high transaction fees or cause you to accidentally approve a malicious transaction. These tokens are designed to take your crypto, not give you anything.
What to do if you find a spam token
Stay calm. Receiving a spam token doesn't mean your wallet is compromised. Your funds are safe as long as you don't interact with it.
Don't interact. Don't click, swap, or approve anything related to the token. Even a small interaction could trigger malicious code or result in loss of funds. If it promises free money, ignore it.
Review your approvals. Go to Assets, then Approvals to revoke any suspicious or unnecessary permissions. Be cautious of contracts that charge unusually high fees to revoke, as these are likely fake approval scams.
Report it. If you spot spam tokens or suspicious transactions in your history, report them to Binance.US Support.
How to protect yourself
Use your Binance.US Wallet's built-in security. Your Binance.US Wallet actively detects spam token transfers and suspicious approvals, filtering them out before they reach your screen. High-risk tokens and addresses are flagged with a warning symbol, helping you steer clear before it's too late.
Always double-check token details. If something feels off, pause and verify. Check the contract address before taking any action. A quick check can save you from a costly mistake.
Stay informed. Scams are constantly evolving. Keeping up with the latest tactics is one of the best ways to protect yourself.
