In the fast-evolving world of cryptocurrency, conducting thorough due diligence (DYOD) is no longer optional—it's essential. With thousands of new tokens launched daily, many of which are scams or poorly designed projects, investors need reliable tools to assess risk before committing funds. While community sentiment, whitepapers, and social media presence offer surface-level insights, real dangers often lie hidden within the smart contract code itself.
Understanding Solidity—the programming language behind Ethereum-based contracts—can be a barrier for most retail investors. That’s where advanced analysis tools come in. By automatically scanning contracts for red flags, these systems empower users to make informed decisions without needing to read a single line of code.
This guide dives deep into the core components of smart contract evaluation, focusing on security checks, trading parameters, liquidity health, and creator transparency—key indicators that can help you avoid traps and identify promising opportunities.
🔒 Critical Security Checks Every Investor Should Know
Before investing in any token, it's crucial to evaluate its underlying security features. Automated tools like Mizar analyze smart contracts and flag potential risks using clear, actionable labels.
Honeypot Detection
A honeypot is a malicious token designed to trap buyers. While users can purchase the token, they’re unable to sell it—only the creator retains selling privileges. This scam drains liquidity from unsuspecting traders. Mizar identifies such contracts by simulating buy and sell transactions during analysis.
High Buy/Sell Taxes
Excessive taxation on trades can severely limit profitability. Tokens with buy or sell taxes exceeding 10% are flagged as high-tax contracts. These fees are often used to fund marketing or development but can also be abused to drain investor value over time.
Token Controlled
If the creator owns more than 10% of the total supply, the token is marked as "controlled." Centralized ownership increases the risk of sudden dumps or manipulation, especially in low-market-cap tokens.
Low Liquidity
Liquidity ensures you can enter and exit positions smoothly. Tokens with less than $25,000 in their largest liquidity pool are classified as low liquidity. Thin markets are vulnerable to price manipulation and slippage, making them risky for traders.
Ownership Not Renounced
When a contract’s ownership rights have not been renounced, the creator retains control over critical functions—such as changing tax rates or pausing transfers. Permanent renouncement is a strong signal of trustworthiness.

📈 Understanding Trading Parameters
Beyond security, trading mechanics play a major role in your experience as a holder or trader. These parameters influence how freely tokens can be bought, sold, and held across wallets.
Buy Tax & Sell Tax
These percentages represent the fee deducted from each transaction:
- Buy Tax: Reduces the number of tokens received when purchasing.
- Sell Tax: Decreases proceeds when converting tokens back to ETH or stablecoins.
High or dynamic taxes can erode returns, especially during volatile price movements.
Max Buy, Max Sell, and Max Wallet
These limits are designed to prevent whale dominance and promote fair distribution:
- Max Buy: Caps the amount one wallet can acquire in a single transaction.
- Max Sell: Restricts how much can be sold at once, reducing dump risks.
- Max Wallet: Limits total holdings per address, promoting decentralization.
While these features enhance fairness, overly restrictive limits may hinder liquidity and tradability.
🌊 Evaluating Liquidity Health
Liquidity is the lifeblood of any tradable token. Without sufficient depth, even legitimate projects can suffer from extreme volatility and poor execution.
Mizar analyzes liquidity pools primarily on Uniswap v2.0 and v3.0, identifying key data points:
- DEX: Specifies whether the pool operates on Uniswap v2 or v3.
- Pair: Only ETH and stablecoin pairs (e.g., USDT, DAI) are displayed for clarity and relevance.
- Price: Real-time token valuation based on the selected pool.
- Pool Address: The blockchain address of the liquidity pool for verification purposes.
- Pool Liquidity: Total value locked (TVL), split evenly between the token and its paired asset (e.g., 50% ETH / 50% token).
- Liquidity / Market Cap Ratio: A vital metric indicating resilience. A higher ratio suggests stronger backing relative to market cap—ideal if above 20–30%.
A low ratio may indicate an inflated market cap unsupported by actual liquidity, increasing vulnerability to rug pulls.

🧠 Analyzing Creator and Owner Information
Transparency around ownership builds trust. Mizar surfaces critical details about the wallet(s) controlling the contract:
- Address: Public identifier of the creator or owner.
- Balance: Current number of tokens held.
- Percent: Proportion of total supply owned.
A large holding percentage (>10%) raises concerns about centralization. Additionally, tracking whether this wallet engages in frequent selling activity post-launch can reveal intent—sudden large sales may signal a lack of long-term commitment.
Monitoring these behaviors helps distinguish genuine developers from opportunistic actors.
Frequently Asked Questions (FAQ)
What is a honeypot in crypto?
A honeypot is a deceptive smart contract that allows purchases but blocks sales. Victims can buy tokens but cannot sell them, effectively locking their funds.
How do I check if a token has high taxes?
Use analytical platforms like Mizar to scan the contract. Any buy or sell tax above 10% should be considered high and carefully evaluated.
Why is low liquidity dangerous?
Low liquidity leads to high slippage and price manipulation. A small sell order could crash the price, making it hard to exit positions at fair value.
What does "ownership not renounced" mean?
It means the developer still holds administrative control over the contract and can potentially change rules, mint new tokens, or withdraw liquidity.
Can I trust tokens with max wallet limits?
Yes, in most cases. These limits prevent whales from dominating and support fairer distribution. However, ensure they’re not so strict that they hinder normal trading.
Is it safe to invest in tokens with no audits?
Generally not recommended. While some legitimate projects launch without audits, an independent audit significantly reduces risk by verifying code integrity.
Stay Ahead with Real-Time Insights
Monitoring trending contracts gives you insight into what other investors are watching. Tools that highlight frequently searched tokens help identify emerging interest before price movements occur.
Whether you're scanning for new opportunities or validating a potential investment, combining automated analysis with informed judgment is your best defense against risk.
