Honeypot token checker on Ethereum
Reviewed 2026-06-25
Answer: A honeypot token on Ethereum lets you buy but blocks you from selling. To check before buying, scan the Ethereum token contract for trade locks, sell-tax traps, and ownership red flags — a scan returns a 0-100 risk score in under ten seconds.
The problem on Ethereum
Honeypot tokens exist on every chain including Ethereum. The trap is the same: buy goes through, sell is blocked by the contract. One check before buying avoids the position entirely.
A scan takes less time than it takes to regret skipping it — and individual checks are always free.
Warning signs to watch for
- Buy simulation succeeds but sell simulation fails or reverts
- Owner-adjustable or hidden sell tax above 10%
- Owner can pause trading or mint new supply at will
- Liquidity is not locked or was recently removed
Any one of these is a reason to check before acting. Several at once is a reason to stop.
What the Ethereum scanner checks
The Ethereum token scanner runs buy and sell simulations and reads the contract bytecode for known trap patterns: sell locks, owner-adjustable tax, mint functions, and unlocked liquidity. Nothing is broadcast — the scan is entirely read-only.
How to run the Ethereum check
- Open the scanner at https://app.web3defender.tech and select Token.
- Paste the Ethereum token contract address.
- Read the 0-100 risk score and listed flags.
- If risk is high, do not buy — the check costs nothing.
General protection habits
- Check before connecting — not after. The scan is free and read-only.
- Revoke approvals you no longer use. Unlimited idle approvals are the most common attack surface.
- Open dApps from bookmarks — never from DM links or social-media ads.
- Treat urgency as a warning sign to slow down, not speed up.
- Legitimate services never DM you first or ask you to sign anything outside the official app.
Frequently asked questions
How accurate is a Ethereum honeypot check?
A simulation runs buy and sell in the same block and reads the bytecode for trap patterns. False positives are rare on established chains. Treat any high score as a reason to wait.
Can a honeypot on Ethereum be reversed?
Only by the contract owner — which almost never happens in favour of buyers. Treat a failed sell simulation as a permanent trap.
Does the Ethereum token scan cost gas?
No. The scan reads on-chain data and simulates trades off-chain. Nothing is signed or broadcast.
