How to Spot Crypto Scams Using a Block Explorer
Home › Guides · By BscScan.Support Editorial · 5 min read · Updated July 2026
Most crypto scams work because the victim never checks the chain. A block explorer is a free lie detector — here are the frauds it catches.
The fake payment screenshot
A "buyer" sends a wallet screenshot showing a transfer to you. Screenshots are trivial to fake. Ask for the transaction hash and look it up. No hash, or a hash that doesn't resolve, or one whose recipient isn't your address — no payment. Never release goods on a screenshot.
Address poisoning
Scammers send worthless dust to your wallet from an address crafted to have the same first and last characters as one you regularly pay. Later, when you copy an address from your transaction history, you copy theirs. Defense: verify the entire address on the explorer before sending, or use a fresh copy from the real recipient, never from history.
The honeypot token
A token pumps and everyone seems to be buying — but the contract is coded so only the creator can sell. Before buying an unknown token, open its contract address on the explorer. Warning signs: the contract is unverified (no public source code), it was deployed days ago, and its transfer activity shows many buys but no successful sells from regular wallets.
The "support agent" and the seed phrase
No explorer, exchange, or wallet company will ever DM you first, and none of them ever need your seed phrase or private key — not to "verify," "sync," "unstake," or "recover" anything. Anyone asking for those words is stealing from you, full stop. A blockchain explorer like this site only reads public data; it never asks you to connect a wallet or enter secrets.
The fake giveaway
"Send 1 BNB, receive 2 back." Look up the collection address: you'll find a stream of incoming transfers and zero outgoing gifts. The chain shows exactly what these schemes are.
The golden rule
Blockchain transactions are irreversible. There is no fraud department, no chargeback, no undo. That's why thirty seconds of verification on an explorer — before you send — is the most valuable habit in crypto.
Frequently asked questions
I already sent money to a scammer. Can anyone recover it?
Realistically no — transactions are irreversible. Report to local police and the platform where contact happened. Beware 'recovery services': almost all are second-round scams targeting victims.
Is a verified contract automatically safe?
No. Verification only means the source code is public. Read what the code does — or check independent audits — before trusting it with funds.
