Main Takeaways
Spam tokens are designed to trick you into interacting with them, potentially opening doors for criminals to compromise your funds.
If you find spam tokens in your wallet, stay calm: your funds remain safe as long as you don't engage.
Protect yourself by using security-forward wallets, always double-checking token details, and staying informed on the latest scam tactics.
Ever found a random token in your crypto wallet and thought, “I definitely didn’t buy that”?
You might’ve just been spammed – yes, even crypto has junk mail.
In the open world of blockchain, anyone can send tokens to anyone else. Sounds empowering, right? But that same freedom also opens the door to a less savory side of decentralized finance: spam tokens. These uninvited guests show up in your wallet, looking flashy or official – but they often carry risks, from honeypot traps to shady links designed to swipe your funds. Let’s dive into what spam tokens are, why they exist, and how you can keep your wallet clean and scam-free – no tech degree required.
How to Tell Spam From the Real Deal
Spam tokens are the crypto version of fake coupons stuffed into your mailbox – unwanted, flashy, and often designed to trick. Scammers airdrop these tokens to thousands of wallets, hoping someone will take the bait. So, how do you identify them?
First, check the source. If a token suddenly appears in your wallet and you didn’t buy it, trade for it, or earn it – it’s probably spam. These tokens often come from nowhere and have no link to your past activity.
Next, look at the name. Tokens with names like “USDT2,” “FreeETH,” or “BonusAirdrop” are waving red flags. Some are more subtle, impersonating popular tokens like BNB or USDT — but don’t be fooled. A quick giveaway? Their token icons are often missing or look off. That’s because they usually lack proper metadata, unlike the real deal.
Then there’s the value. Spam tokens often pretend to be worth a fortune – until you try to cash them out. Spoiler alert: you can’t.
You can also peek at the token’s on-chain data. If it has tons of transfers but very few holders, it’s a strong sign something’s off. Legitimate tokens usually have a lot of holders.
Finally, if you’re tech-savvy, check the token’s smart contract. Many spam tokens have unverified or hidden code – because they don’t want you to see what’s really going on under the hood.
In short: if it appears out of nowhere and looks strange – it’s likely spam. And in the world of crypto, spam is not innocent.
What’s in it for the Spammers?
Spammers aren’t just filling up your wallet for fun. They’ve got a plan, and it’s all about getting to your crypto. Here’s how they usually operate:
Distract: By cluttering your wallet with random tokens, scammers hope to confuse you, especially during trades. Imagine trying to swap stablecoins for ETH, only to accidentally select a fake ETH token instead. One small slip, and your real funds are gone.
Entice: Some scammers go a step further by adding liquidity to these spam tokens, artificially inflating their value to make them look like the next big thing. The goal? To lure you into buying more. But here’s the trap: once you buy in, you often can’t sell it.
Trick: Some spam tokens come with messages like “Claim your prize!” or embed phishing links right in their token names. These shady URLs lead to fake websites designed to steal your private info — from wallet credentials to seed phrases.

Steal: Interacting with a spam token might trigger high transaction fees or cause you to accidentally approve a scammy transaction. Always double-check before you click – these tokens are designed to take your crypto, not give you anything of any value.
Real-Life Example: The ACT Spam Token
Scammers created a fake token mimicking the popular ACT token, then faked transfer events to make it appear as though Binance’s hot wallet was airdropping these tokens to make it look more legitimate. The aim was to trick users into interacting with the token, leading them straight into a trap where they’d lose funds.
What To Do if You Find Spam Tokens in Your Wallet
Step 1: Stay Calm
First things first: your wallet is not compromised. Receiving spam tokens does not mean your funds are at risk.
Step 2: Don’t Interact
Avoid clicking, swapping, or approving anything related to the spam tokens. Even a small interaction could trigger malicious code or potential loss of funds. Ignore offers of “free money” – as ever, if it seems too good to be true, it probably is. If you're unsure, use portfolio trackers like DeBank to help filter out spam tokens automatically.
Step 3: Double-Check Permissions
Revoke any suspicious and unnecessary approvals by visiting the in-wallet approval page. This ensures that smart contracts that you no longer need are denied access to your wallet. Be cautious of contracts that require unusually high fees to revoke — they’re likely fake approval scams.
Step 4: Report
If you find any spam tokens or suspicious transactions in your history, report them to customer support on official platforms.

Choose a Security-Forward Wallet
A security-forward wallet – like Binance Wallet – does more than just hold your crypto.
