Token Safety Checker
Check if a crypto token is safe. Detect honeypots, rug pulls, hidden taxes, and unlocked liquidity.
Fear & Greed Index
Real-time crypto market Fear & Greed sentiment index with history.
Instantly check if a token is a honeypot, verify contract safety, and review holder distribution before you trade.
Before investing in any cryptocurrency token, performing a thorough safety check is essential to protect your funds. Thousands of new tokens launch every week across Ethereum, BNB Chain, Polygon, Arbitrum, Base, and other networks. While many are legitimate projects, a significant number are designed to scam investors through honeypots, rug pulls, and hidden tax manipulation.
Our free token safety checker analyzes smart contracts in real time by examining multiple security factors: honeypot detection, buy and sell tax rates, liquidity lock status, contract verification, ownership renouncement, and holder distribution. Each factor contributes to an overall safety score from 0 to 100 that gives you an instant assessment of the token's risk level.
To use the checker, simply paste the token's contract address (the 0x address you can find on any block explorer or token listing), select the correct blockchain network, and click Check. Within seconds, you will receive a detailed safety report. A score above 70 generally indicates a safer token, while anything below 40 should be treated as high risk. Always combine this tool with your own research -- check the project's website, social media presence, team background, and community activity before making any investment decision.
For ongoing portfolio safety, consider using our DCA Optimizer to reduce risk through dollar-cost averaging, monitor overall market conditions with the Crypto Fear & Greed Index, and track your holdings with real-time prices on our coin tracker.
A honeypot token is a malicious smart contract that allows you to buy but prevents you from selling. Our checker simulates a buy and sell transaction on-chain to verify that both operations complete successfully. If the sell transaction fails or reverts, the token is flagged as a honeypot.
Many tokens implement transfer taxes that take a percentage of every buy or sell. While small taxes (1-3%) can be legitimate for funding development or liquidity, excessive taxes above 10% are a major red flag. Some scam tokens start with low taxes and increase them later using modifiable tax functions.
Locked liquidity means the token developer has deposited trading pair tokens into a time-locked smart contract and cannot withdraw them. This protects buyers from "rug pulls" where a developer removes all liquidity, crashing the price to zero. We check if liquidity pool tokens are locked and for how long.
A verified contract has its source code published and confirmed to match the deployed bytecode on the blockchain. Unverified contracts hide their code, making it impossible to audit what the token actually does. Verified contracts can be reviewed by anyone for malicious functions.
When a contract owner renounces ownership, they permanently give up the ability to modify the contract. This means no one can change taxes, pause trading, blacklist wallets, or mint new tokens. Renounced ownership is a strong safety signal, though some legitimate projects retain ownership for necessary upgrades.
Analyzing how tokens are distributed across wallets reveals concentration risk. If a small number of wallets hold a large percentage of the total supply, those wallets can crash the price by selling. Healthy tokens typically have broad distribution with no single non-contract wallet holding more than 5%.
Developers create a token, add liquidity to attract buyers, then remove all liquidity and disappear with investor funds. Look for locked liquidity and renounced ownership to protect yourself.
The token contract allows buying but blocks selling through hidden code. Victims see their token value increase but can never cash out. Always run a safety check before buying any new token.
Instead of pulling all liquidity at once, developers gradually sell their large token holdings over time, slowly draining value. Watch for wallets that hold 10% or more of the total supply.
Tokens that start with low or zero taxes to attract buyers, then the owner increases the sell tax to 90-100%, effectively trapping funds. Check if the contract owner can modify tax rates.
Scammers create artificial trading volume and liquidity that appears legitimate but is controlled by the same wallet. Verify that liquidity comes from multiple independent providers.
Paste the token's contract address into our free safety checker above and select the blockchain it's deployed on. Our tool analyzes the smart contract for honeypot behavior, excessive buy/sell taxes, liquidity lock status, contract verification, ownership status, and holder distribution. You'll receive a safety score from 0 to 100 along with a detailed breakdown of each risk factor within seconds.
A honeypot token is a type of crypto scam where the smart contract allows investors to buy the token but prevents them from selling it. The contract contains hidden code that blocks sell transactions, traps your funds, and makes it impossible to cash out. Our checker simulates both buy and sell transactions to detect honeypot behavior before you risk your money.
Liquidity locked means the developer has deposited the trading pair tokens (for example, the token paired with ETH or USDT) into a time-locked smart contract. During the lock period, the liquidity cannot be removed by anyone, including the developer. This protects investors from rug pulls where a developer removes all liquidity and crashes the token's price to zero. Longer lock periods generally indicate stronger commitment from the project team.
Key warning signs of a rug pull include: unlocked liquidity (the developer can withdraw it at any time), a small number of wallets holding a large percentage of the supply, unverified contract source code, the contract owner retaining dangerous permissions like minting or pausing, extremely low holder counts, and anonymous teams with no track record. Our safety checker evaluates all of these factors automatically.
