Someone told you about a token. Maybe it was on Twitter, in a Discord, or from a friend who "got in early." Before you buy anything, run through this due-diligence checklist. It takes 10 minutes and can save you thousands.
Step 1: Check the Contract and Chain
Every token has a contract address. This is the unique identifier on the blockchain. Scammers often create tokens with the same name as popular projects but different contract addresses.
- Find the official contract address โ check the project's official website, CoinGecko, or CoinMarketCap. Never trust a contract address from a DM or random post.
- Verify the contract is verified on Etherscan โ go to Etherscan (or the relevant block explorer), paste the contract address, and check if the source code is published and verified. Unverified contracts are a major red flag.
- Check the deployer wallet โ if the wallet that deployed the contract also deployed 50 other tokens that all went to zero, you have your answer.
Step 2: Analyze the Liquidity
Liquidity is the pool of assets that enables trading. Without sufficient locked liquidity, developers can drain the trading pool at any time โ that's a rug pull.
๐ข Green flags:
โข Liquidity locked via a time-lock contract (Unicrypt, Team.Finance)
โข Lock duration: 6+ months minimum, ideally 1+ year
โข Liquidity pool size: >$100K for serious projects
๐ด Red flags:
โข Unlocked liquidity โ devs can pull it anytime
โข Very small pool (<$10K) โ easy to manipulate price
โข Liquidity lock expires in days/weeks
โข "Trust us, we won't pull" (they will)Tools like DexScreener and DEXTools show liquidity status for most tokens.
Step 3: Evaluate the Team
- Are team members identifiable? โ real names, LinkedIn profiles, past projects. Anonymous teams aren't automatically bad (Bitcoin's creator is anonymous), but they're much higher risk for new projects.
- Do they have a track record? โ have they built anything before? Check GitHub for actual code contribution history.
- Are they reachable? โ can you find them on professional networks? Do they engage in technical discussions, or only in hype?
Step 4: Read the Tokenomics
Tokenomics is how the token supply is distributed and managed:
- What's the total supply? โ a token with 1 trillion supply and a $0.000001 price is not "cheap" โ it may already have a large market cap.
- How much does the team hold? โ if insiders hold 50%+ of supply, a single sell-off can crash the price.
- Are there vesting schedules? โ team and investor tokens should unlock gradually, not all at once.
- Is there a tax on buys/sells? โ some tokens take 10โ20% per transaction. High sell taxes are a red flag (they make it hard to exit).
Step 5: Check Community and Activity
- GitHub activity โ is there actual development happening? Regular commits from multiple contributors is a good sign. An empty or stale GitHub is not.
- Community quality โ are people discussing the technology and product, or just posting price targets and rocket emojis?
- Holder distribution โ check Etherscan's "Holders" tab. If the top 10 wallets hold 80% of supply, the token is extremely concentrated.
Quick Red Flag Summary
Any single red flag is a warning. Three or more? Walk away. No token is worth the risk.
- โ Anonymous team with no prior work
- โ Unverified smart contract
- โ Unlocked or tiny liquidity
- โ "Guaranteed" returns promised
- โ High sell tax (makes it hard to exit)
- โ No GitHub or development activity
- โ Only hype, no product
- โ Pressure to "buy now before it moons"
