Token Sniffer Features and How it Works
Token Sniffer works by analyzing blockchain transactions and checking token addresses to identify any suspicious activity.
Once the user enters the contract address, the tool will perform analysis in three main categories:
1. Contract Analysis
Detecting possible honeypots, the owner's ability to modify contracts, and verifying the source of contracts.
2. Owner Analysis
View token ownership by contract owners and creators. Tokens receive a green (good) checkmark if ownership is below 5% of the total supply.
3. Liquidity Analysis
Shows the distribution of token liquidity across different DEXs. The more liquidity across different DEXs, the better.
Based on this analysis, Token Sniffer assigns a security score from 0 to 100.
If a smart contract gets a green tick in all categories, the score obtained is 100.
However, the tool also emphasizes that high-scoring tokens may still have hidden bugs.
