Reading a Token on Etherscan/Solscan: A Simple Walkthrough
Learn to analyze token contracts, check holders, liquidity, and spot red flags using blockchain explorers. Essential DYOR skills for crypto safety.
Every day, thousands of new tokens launch across Ethereum and Solana. Most are scams, rug pulls, or low-effort projects destined to fail. The difference between getting rekt and making smart investments often comes down to one skill: reading blockchain explorers.
Etherscan and Solscan are your detective tools in the crypto world. They show you everything: who holds what, how much liquidity exists, whether contracts are verified, and if developers are dumping their bags. This information is all public—you just need to know where to look.
This guide walks through the exact process of analyzing a token using blockchain explorers. By the end, you'll know how to spot red flags, verify legitimacy, and make informed decisions based on on-chain data rather than hype.
Getting Started: Understanding Blockchain Explorers
Blockchain explorers are websites that let you search and view blockchain data in a user-friendly format. Think of them as Google for blockchains—you can look up any address, transaction, or smart contract.
Etherscan (Ethereum)
- • URL: etherscan.io
- • Covers: Ethereum mainnet and ERC-20 tokens
- • Features: Contract verification, holder analysis, transaction history
- • Best for: Ethereum-based tokens and DeFi protocols
- • Alternative: Etherscan also covers other EVM chains
Solscan (Solana)
- • URL: solscan.io
- • Covers: Solana blockchain and SPL tokens
- • Features: Token metrics, holder distribution, program analysis
- • Best for: Solana meme coins and DeFi protocols
- • Alternative: Solana Explorer is the official option
What You Can Research:
Token Information
- • Total supply and circulating supply
- • Contract address and creation date
- • Token name, symbol, and decimals
- • Contract verification status
- • Creator wallet and initial distribution
Market Data
- • Holder count and distribution
- • Liquidity pool information
- • Trading volume and patterns
- • Large wallet movements
- • Developer and team wallet activity
Why This Matters
Marketing can lie, social media can be faked, and influencers can be paid—but blockchain data doesn't lie. When a developer claims they "burned" their tokens but you can see them sitting in their wallet, that's valuable information. When a project claims strong community support but 80% of tokens are held by 3 wallets, that's a red flag.

Step-by-Step: Analyzing a Token Contract
Let's walk through the exact process of researching a token. I'll use a hypothetical ERC-20 token, but the same principles apply to Solana SPL tokens with slight interface differences.
Step 1: Find the Contract Address
The contract address is the token's unique identifier on the blockchain. Always get this from official sources, not random links or DMs.
Trusted Sources:
- • Official project website or documentation
- • Verified social media accounts
- • CoinGecko or CoinMarketCap listings
- • DEX listings (Uniswap, PancakeSwap, etc.)
Warning: Scammers create fake tokens with similar names. Always verify the contract address matches official sources.
Step 2: Basic Contract Information
Once you paste the contract address into Etherscan/Solscan, check these basic details first:
Essential Checks:
- • Contract verified: Green checkmark next to contract
- • Creation date: When was it deployed?
- • Total supply: How many tokens exist?
- • Decimals: Usually 18 for ERC-20, 9 for SPL
- • Creator address: Who deployed the contract?
Red Flags:
- • Contract not verified (major red flag)
- • Created very recently (less than 24 hours)
- • Suspicious total supply (trillions of tokens)
- • Creator address is a known scammer
- • Contract has unusual or hidden functions
Step 3: Holder Analysis
Click on the "Holders" tab to see token distribution. This is one of the most important analyses you can do.
What to Look For:
- • Top holder percentage: Should be <20% ideally
- • Distribution spread: Hundreds or thousands of holders
- • Whale concentration: Top 10 holders <50%
- • Exchange wallets: Major exchanges holding tokens
- • Dead/burn wallets: Tokens sent to unusable addresses
Danger Signs:
- • Single wallet holds >50% of supply
- • Very few holders (less than 100)
- • Developer wallets holding massive amounts
- • Suspicious wallet clustering (same entity, multiple wallets)
Step 4: Liquidity and Trading Analysis
Check the "Transfers" or "Transactions" tab to understand trading patterns and liquidity.
Healthy Patterns:
- • Regular trading activity
- • Variety of transaction sizes
- • Multiple DEX platforms
- • Liquidity pool locks or burns
- • Organic growth in transactions
Warning Signs:
- • All transactions from same few wallets
- • Sudden massive sell-offs
- • Liquidity can be removed anytime
- • Suspicious trading patterns (wash trading)
- • Very low liquidity relative to market cap
Step 5: Contract Code Review
If the contract is verified, click on "Contract" tab to review the source code.
What to Look For (Basic):
- • Standard ERC-20 or SPL implementation
- • No hidden mint functions
- • No blacklist or pause functions
- • Reasonable transfer fees (if any)
- • Ownership renounced or multi-sig
Major Red Flags:
- • Contract not verified at all
- • Hidden or obfuscated functions
- • Ability to mint unlimited tokens
- • High transfer taxes or fees
- • Functions to blacklist addresses
Pro Tips for Efficient Analysis
- • Use multiple tabs: Open the token page, holders, and transactions simultaneously
- • Check recent activity: Sort transactions by newest to see current trading patterns
- • Follow the money: Click on large holder addresses to see their other holdings
- • Cross-reference: Verify information on multiple explorers when possible
- • Save screenshots: Document your research for future reference
Red Flags and Scam Detection
Recognizing scams and rug pulls through on-chain analysis can save you from devastating losses. Here are the most common patterns and how to spot them early.
Immediate Disqualifiers
These red flags should make you walk away immediately, regardless of other factors:
Contract Issues:
- • Contract not verified
- • Mint function still active
- • Owner can pause transfers
- • Blacklist functionality
- • Extremely high transfer taxes (>10%)
Distribution Issues:
- • Single wallet holds >70% supply
- • Dev team holds >30% supply
- • Less than 50 total holders
- • All liquidity from one source
- • Liquidity can be removed instantly
Honeypot Detection
Honeypots are tokens you can buy but can't sell. They're designed to trap your money.
How to Check:
- • Look for sell transactions in recent history
- • Check if different wallets can successfully sell
- • Use honeypot detection tools (honeypot.is, tokensniffer.com)
- • Test with very small amounts first
Honeypot Indicators:
- • Only buy transactions, no successful sells
- • Failed sell transactions in history
- • Transfer restrictions in contract code
- • Unusually high "buy pressure" with no sells
Rug Pull Patterns
Rug pulls happen when developers drain liquidity or dump massive token holdings.
Early Warning Signs:
- • Dev wallets moving large amounts
- • Liquidity being slowly drained
- • Team members going silent
- • Sudden changes to tokenomics
- • Marketing promises not delivered
Protection Measures:
- • Check for liquidity locks
- • Monitor dev wallet activity
- • Look for burned LP tokens
- • Renounced contract ownership
- • Multi-sig wallets for team funds
Bot and Wash Trading Detection
Fake volume and bot trading can make tokens appear more popular than they are.
Suspicious Patterns:
- • Same wallets buying and selling repeatedly
- • Identical transaction amounts and timing
- • High volume but few unique traders
- • Price manipulation around key levels
- • MEV bot activity (front-running transactions)
Reality Check: Look at unique wallet count vs. transaction volume. A token with 1000 transactions but only 50 unique wallets is likely bot-manipulated.
Advanced Analysis Techniques
Once you're comfortable with basic analysis, these advanced techniques can give you deeper insights into token fundamentals and market dynamics.
Wallet Clustering Analysis
Follow connections between wallets to understand true ownership concentration and identify coordinated activities.
Techniques:
- • Click on large holder addresses to see their transaction history
- • Look for funding patterns (same source wallet funding multiple addresses)
- • Check if wallets interact with same contracts/exchanges
- • Identify potential sybil attacks (one entity, many wallets)
Example Pattern:
If 10 different "holder" wallets all received their initial funding from the same source wallet, they might all be controlled by one entity, making the distribution more centralized than it appears.
Liquidity Pool Analysis
Understanding liquidity mechanics helps you assess price stability and exit liquidity.
Key Metrics:
- • Total Value Locked (TVL) in pools
- • Token/ETH or Token/SOL ratio
- • LP token distribution and locks
- • Multiple DEX listings
- • Pool creation dates
Warning Signs:
- • Single liquidity provider
- • No LP token locks
- • Liquidity much smaller than market cap
- • Recent massive liquidity removals
- • Unbalanced pool ratios
Historical Analysis
Study how the token has evolved over time to understand development patterns and community growth.
Timeline Analysis:
- • Contract deployment and first transactions
- • Initial distribution events
- • Major holder changes over time
- • Volume and activity trends
- • Development milestone correlations
Growth Patterns:
- • Holder count growth rate
- • Trading volume consistency
- • Whale accumulation vs. distribution
- • Community engagement correlation
Smart Contract Security Assessment
For those comfortable with code, reviewing smart contracts can reveal hidden risks and functionalities.
Basic Code Review:
- • Check for standard ERC-20/SPL implementation
- • Look for unusual functions or modifiers
- • Verify ownership and admin functions
- • Check for external dependencies
- • Review upgrade mechanisms
Tools for Non-Coders:
- • Token Sniffer: Automated contract analysis
