How to Do a Free Token Contract Audit

Professional smart contract audits cost $5,000-$50,000. But you can do a basic security check for free.

What You Can Check for Free

1. Bytecode Analysis (Our Scanner)

Our free scanner analyzes the actual bytecode on-chain:

  • Detect honeypot functions
  • Find mint functions
  • Check owner privileges
  • Score overall risk (1-10)

No signup. No wallet. Free.

2. Basescan Manual Check

  1. Go to Basescan
  2. Search the contract address
  3. Click "Contract"
  4. Check "Verified" status
  5. Read the source code

Look for:

  • onlyOwner modifiers on critical functions
  • blacklist or _isBlacklisted
  • pause / unpause functions
  • mint with unlimited amounts

3. DexScreener Deep Dive

Check the trading chart:

  • Is liquidity locked?
  • How old is the pool?
  • What's the holder distribution?

4. Social Due Diligence

  • Does the project have a website?
  • Is the team visible?
  • Are there real community members?

When to Pay for an Audit

Free checks are great for initial screening. For serious investments (>$1K), consider a professional audit.
