Honeypot Detector & Token Security Scanner
Paste any token contract address and find out if it is a honeypot before you buy. OnChainRisk simulates buy and sell transactions on-chain, detects hidden taxes, blacklist functions, and scores token security across 7 categories.
What Is a Honeypot Token?
A honeypot is a token contract that lets you buy but blocks you from selling. The contract code contains hidden functions that prevent sell transactions, charge 90-100% sell tax, or blacklist buyers after purchase. Thousands of honeypot tokens are deployed every day across Ethereum, BNB Chain, and L2 networks.
What the Honeypot Detector Checks
Buy/Sell Simulation
We simulate actual buy and sell transactions on the DEX pair (Uniswap, PancakeSwap, etc.) to measure the real tax applied:
- Buy tax percentage
- Sell tax percentage
- Whether sell is completely blocked
- Max transaction amount limits
Bytecode Analysis
The scanner decompiles the contract bytecode and checks for dangerous functions:
- Blacklist/whitelist functions
- Owner-only transfer restrictions
- Hidden mint functions
- Proxy/upgradeable contract patterns
Token Security Score: 7 Categories
Each token gets a 0-100 security score based on these categories:
Ownership
Is the contract owned? Can the owner change rules?
Mint Authority
Can new tokens be minted after deployment?
Fee/Tax
Are there buy/sell fees? Can they be changed?
Blacklist
Can specific addresses be blocked from trading?
Proxy
Is the contract upgradeable? Can behavior change?
Liquidity
Is LP locked? For how long? What percentage?
Holders
Top holder concentration. Whale risk assessment.
Holder Distribution Visualization
The Token Check page includes a bubble chart showing holder distribution. Quickly spot if the top 10 wallets hold 80% of supply (rug pull risk) or if holdings are spread across thousands of wallets (healthier distribution).
Supported Networks
The honeypot detector works on any EVM-compatible chain with DEX pairs:
How to Use the Honeypot Detector
