You found a token that looks promising. The chart is moving up. The Telegram group is buzzing. You buy in — and then you try to sell. Nothing happens. Or worse, the transaction goes through but returns almost nothing. You’ve just hit a sell restriction, and in many cases, it means you’ve walked into a honeypot scam.
Sell restrictions are coded directly into a token’s smart contract. They can block sales entirely, cap how much you can sell at once, apply hidden taxes of 50–99%, or limit selling to whitelisted wallets only. The token looks real. The liquidity looks real. But the exit doesn’t exist — at least not for you. This is one of the most common ways new DeFi investors lose money.
The good news: most crypto token sell restrictions are detectable before you invest. There are free and paid tools that scan smart contract code, simulate transactions, and flag suspicious patterns in seconds. This guide walks you through exactly how to use them — and what to look for when the tools aren’t enough.

Tool Breakdowns: Features, Pros, Cons & Best For
1. Honeypot.is — Best for Instant Honeypot Detection
Best for: Anyone who wants a fast, free, one-step answer on whether a token can be sold.
Honeypot.is is the most widely used tool for detecting sell restrictions in DeFi. Paste a token contract address, select the chain, and it simulates a buy and sell transaction in seconds. It tells you the exact buy tax, sell tax, and whether the sell will succeed at all. The result is binary and clear: “Is Honeypot: YES” or “Is Honeypot: NO.” There’s no jargon to decode.
The tool covers Ethereum, BNB Chain, Arbitrum, Base, and several other EVM-compatible networks. It’s fully free with no account required. For a first-pass check before buying any new token, this should be your default starting point. It won’t catch every exploit, but it catches the most common sell-restriction patterns reliably.
✅ Pros
- Completely free — no signup required
- Simulates actual buy and sell transactions
- Returns exact tax percentages on buy and sell
- Clear pass/fail result — no technical knowledge needed
- Covers major EVM chains including Base and Arbitrum
- Fast — results in under 5 seconds
❌ Cons
- Does not audit broader contract logic or ownership risk
- Can be fooled by contracts with time-delayed restrictions
- No Solana or non-EVM chain support
- Simulation may not reflect owner-triggered restrictions
- No wallet-level risk analysis

2. GoPlus Security — Best for Comprehensive Risk Breakdown
Best for: Investors who want a full picture of contract risk, not just a honeypot check.
GoPlus Security runs the deepest automated scan of any free tool on this list. It checks over 30 risk indicators including: whether the contract owner can pause trading, whether mint functions are active, whether there’s a blacklist function, whether sell taxes are hardcoded or modifiable, and whether the liquidity is locked. It supports 30+ blockchain networks, including Solana, making it one of the few tools that works beyond EVM chains.
The API is also publicly available, which means it powers security warnings inside many popular DEX interfaces and wallet apps. If you’ve seen a risk score inside a DEX before, there’s a good chance GoPlus was behind it. For anyone doing serious token research, this is the most thorough free resource available.
✅ Pros
- 30+ risk checks in a single scan
- Supports 30+ chains including Solana and non-EVM networks
- Detects modifiable tax functions — not just current rates
- Checks blacklist and whitelist functions specifically
- Free to use via web interface and public API
- Powers risk data inside many wallets and DEXes
❌ Cons
- Results require some DeFi literacy to interpret
- UI is less intuitive than Honeypot.is for beginners
- Automated checks can miss novel contract exploits
- No transaction simulation — analysis only
- High-risk flags can occasionally produce false positives

3. Token Sniffer — Best Automated Contract Audit
Best for: Getting a scored audit report on a token’s contract without reading the code yourself.
Token Sniffer runs an automated audit on any ERC-20 or BEP-20 token and returns a score out of 100. The audit checks for contract similarities to known scam templates, the presence of dangerous functions, owner privileges, liquidity status, and more. It also shows recently flagged scam tokens, which is useful for cross-referencing a new project against known bad actors.
The score is a useful shorthand. A token scoring below 50 warrants serious caution. Above 80 doesn’t mean it’s safe — but it means the contract passes basic automated checks. Use this in combination with Honeypot.is for a faster two-step safety check before committing capital.
✅ Pros
- Scored audit report — easy to interpret at a glance
- Compares contract to known scam code templates
- Shows recently detected scam tokens
- Checks liquidity lock status
- Free to use with no account required
- Good for quick cross-referencing
❌ Cons
- Limited to Ethereum and BNB Chain
- Automated audits miss custom or novel exploits
- Score can give false confidence if taken in isolation
- No transaction simulation
- Less detailed than GoPlus on specific risk categories

4. DEXTools — Best for Live Chart and Audit Combined
Best for: Traders who want price data and safety checks on one screen.
DEXTools is primarily a charting and trading analytics platform, but it integrates token audit scores directly into its interface. When you view a token’s chart on DEXTools, you’ll see an audit badge from GoPlus or a partner provider. You can also see the token’s liquidity lock status, top holders, and recent transactions — all of which help you spot manipulation patterns.
The free tier is sufficient for most checks. The paid DEXT Premium plan unlocks faster data, deeper analytics, and multi-chain tools. For new investors who want to research a token before buying without jumping between multiple tabs, DEXTools is the most convenient single-window solution.
✅ Pros
- Chart, audit, and holder data on one screen
- Integrated GoPlus audit scores
- Liquidity lock status visible at a glance
- Top holder concentration shown in percentage
- Active community and token ratings
- Multi-chain support on paid tier
❌ Cons
- Free tier has data delays and limited chain access
- Audit score is sourced externally — not proprietary
- No transaction simulation built in
- Interface has a learning curve for new DeFi users
- Premium plan required for full feature access
5. De.Fi Scanner — Best for Portfolio-Wide Token Scanning
Best for: Investors who want to scan all tokens in their wallet at once, not just one at a time.
De.Fi Scanner lets you connect your wallet and scan every token you hold in a single pass. It flags risky contracts, checks for active exploits, and scores each asset. This is particularly useful if you’ve been active in DeFi for a while and hold a large number of tokens — manually checking each one through Honeypot.is would take hours.
The platform also tracks DeFi protocol risks, including whether liquidity pools you’re invested in have experienced abnormal activity. It’s a broader risk management tool rather than a single-token deep-dive. Use it as a regular portfolio health check rather than a pre-buy research step.
✅ Pros
- Scans entire wallet in one pass
- Tracks DeFi protocol risks, not just token contracts
- Clean interface — accessible to non-technical users
- Free tier covers most use cases
- Monitors for newly discovered exploits
- Multi-chain wallet support
❌ Cons
- Requires wallet connection — not anonymous by default
- Less granular than GoPlus on per-token risk factors
- No transaction simulation
- Some risk scores lack detailed explanations
- Best value as an ongoing tool, not a one-time check

6. RugDoc — Best for DeFi Farm and Pool Audits
Best for: Yield farmers and liquidity providers who need pool-level risk checks.
RugDoc focuses on DeFi farms, pools, and yield protocols rather than individual tokens. If you’re about to provide liquidity or stake in a new protocol, RugDoc assesses whether the contract gives developers the ability to drain funds, change reward rates maliciously, or pause withdrawals. These risks are different from token-level honeypots but equally dangerous.
The platform rates each protocol it reviews on a scale from “Bare Minimum” to “Facemelter” (high risk). Community reviews supplement the technical audits. It’s a more manual process than the automated tools above, but for anyone moving significant capital into yield strategies, it’s a worthwhile additional check.
✅ Pros
- Specifically built for DeFi farm and pool risks
- Community reviews add qualitative context
- Catches withdrawal restriction risks at the protocol level
- Free to access all audit reports
- Covers risks that token-only scanners miss
- Useful for staking and LP decisions specifically
❌ Cons
- Not designed for individual token honeypot checks
- Coverage is limited — not all protocols are reviewed
- No automated contract scanning tool
- Less active on newer or smaller chains
- Some reviews are outdated relative to contract updates
→ Check Protocol Safety on RugDoc — Free
7. Etherscan / BscScan — Best for Manual Contract Review
Best for: Experienced investors who want to read the contract code themselves.
Etherscan (for Ethereum) and BscScan (for BNB Chain) are blockchain explorers that give you direct access to a token’s smart contract code. If the contract is verified — meaning the source code is publicly visible — you can read every function yourself. The key functions to look for are: _transfer, setFee, blacklist, isWhitelisted, and anything that modifies the maxSellAmount or applies conditional logic to sells.
This approach requires Solidity literacy, but even without it, you can use the “Read Contract” tab to check current fee percentages, owner address, and whether trading is enabled. An unverified contract — one with no readable source code — is itself a significant red flag worth noting before any other analysis.
✅ Pros
- Fully transparent — you see exactly what the contract does
- No tool intermediary — ground truth source
- Read Contract tab usable without coding knowledge
- Unverified contracts flagged clearly
- Free and always available
- Works for any ERC-20 or BEP-20 token
❌ Cons
- Requires Solidity knowledge for full code review
- No automated flagging or scoring
- Time-consuming — not practical for quick checks
- Obfuscated code can still hide exploits
- Limited to ETH and BSC natively

Buying Guide: How to Check a Token for Sell Restrictions Before You Invest
No single tool catches every exploit. The safest approach is a layered check — run multiple tools in sequence. Here is the exact process to follow before buying any new token.
Step 1 — Find the Contract Address
Never copy a contract address from Telegram, Discord, or social media. Scammers post fake contract addresses that look similar to the real one. Go directly to the project’s official website and copy the address from there. Cross-reference it on CoinGecko or CoinMarketCap if the token is listed. One wrong character means you’re checking the wrong contract entirely.
Step 2 — Run Honeypot.is First
Paste the address into Honeypot.is, select the correct chain, and check the result. If it flags a honeypot or shows a sell tax above 10%, stop here. A sell tax above 10% is prohibitive for most investors and is a common mechanism used to trap buyers. If it passes, note the exact buy and sell tax percentages and move to step three.
Step 3 — Run GoPlus Security
Paste the same address into GoPlus Security. Review the following flags specifically: “Is Honeypot,” “Can Take Back Ownership,” “Hidden Owner,” “Modifiable Tax,” “Blacklist Function,” and “Anti-Whale Modifiable.” Any “Yes” on the first four is a serious warning. A blacklist function is common in legitimate tokens but should be noted — owners can use it to freeze your wallet.
Step 4 — Check the Contract on Etherscan or BscScan
Search the contract address on the relevant explorer. Check three things without reading code: (1) Is the contract verified? No source code visible is a red flag. (2) Who is the owner? An owner address holding a large token percentage is a risk. (3) When was the contract deployed? A token launched hours ago with no audit and rapid liquidity inflow is a classic pump-and-dump pattern.
Step 5 — Check Liquidity Lock Status
Unlocked liquidity means the developer can remove all liquidity at any moment — this is the mechanism behind most rug pulls. Check whether liquidity is locked and for how long using DEXTools, Team.Finance, or Unicrypt. A lock shorter than 6 months on a new token is inadequate. No lock at all is a definitive red flag, regardless of how promising the project looks otherwise.
Step 6 — Check Top Holder Concentration
Open the token on Etherscan or DEXTools and look at the top holder list. If one or two wallets hold more than 20% of supply — excluding the liquidity pool address — that’s a concentration risk. Those holders can dump and crash the price. Exclude the locked liquidity pool address from this calculation; that holding is expected and not a sell risk.
Step 7 — Check Community and Audit History
Search the token name on Token Sniffer’s recently flagged list and on Twitter/X. Has the project been flagged by any security accounts? Has the team published a third-party audit from firms like CertiK, Hacken, or PeckShield? A legitimate project will have an audit report publicly available — not just a claim that one was done. If the only “audit” is a screenshot in the Telegram group, it doesn’t count.
Red Flags: Signs a Token Has Sell Restrictions
Even without running tools, these patterns are warning signs that a token may have sell restrictions baked in.
- Buy transactions succeed but sell transactions fail or revert — the clearest sign of a honeypot
- Sell tax is significantly higher than buy tax — e.g., 1% buy / 25% sell is a trap, not a fee
- Contract is not verified on Etherscan or BscScan — no readable source code is an automatic red flag
- Owner wallet holds mint or pause functions — contract can be changed after you buy
- Liquidity is not locked — developer can remove all liquidity at any time
- Blacklist function exists and is active — your wallet can be blocked from selling
- MaxSellAmount is set extremely low — you may only be able to sell a fraction of your holding at once
- Token was deployed less than 24 hours ago with no audit — insufficient time to assess legitimacy
- Top two wallets hold more than 30% of supply — price is controlled by a small group
- Team is anonymous and there is no whitepaper — no accountability if things go wrong
Frequently Asked Questions
What are sell restrictions on a crypto token?
Sell restrictions are rules coded into a token’s smart contract that prevent or limit selling. They include complete sell blocks (honeypots), high sell taxes (50–99%), maximum sell amount limits, whitelist-only selling where only approved wallets can sell, and blacklist functions where specific wallets are blocked from selling. Most sell restrictions are intentional scam mechanisms, though some legitimate tokens use milder forms for anti-whale or anti-dump mechanics.
How do I check if a token is a honeypot before buying?
The fastest way to check if a token is a honeypot is to use Honeypot.is. Paste the token’s contract address, select the correct blockchain, and the tool simulates a buy and sell transaction. If the sell fails or returns a sell tax above 10%, the token is likely a honeypot. For a deeper check, also run the address through GoPlus Security, which scans over 30 risk indicators including hidden owner functions and modifiable taxes.
Can a token add sell restrictions after launch?
Yes. If a token contract includes an upgradeable proxy, an owner with admin privileges, or a function that allows fee modification, the developer can add or increase sell restrictions after the token is already trading. This is why GoPlus Security’s check for “Modifiable Tax” and “Can Take Back Ownership” matters. A token that passes a honeypot check on day one can become a honeypot on day 10 if the contract allows owner modifications.
What is a safe sell tax percentage on a crypto token?
Most legitimate tokens charge a combined buy and sell tax between 0% and 5%. A sell tax of 5–10% is high but not uncommon in tokens with redistribution or buyback mechanisms. Any sell tax above 10% should be treated as a serious red flag. A sell tax of 25% or more almost always indicates a scam or trap. Always check whether the tax is fixed in the contract or modifiable by the owner — a modifiable tax can be increased to 99% after you’ve bought.
Is it safe to buy a token if Honeypot.is shows no honeypot?
A clean result on Honeypot.is means the token passed a simulated buy and sell test — it does not mean the token is safe to invest in. Honeypot.is only checks for sell restrictions and tax rates at the moment of the scan. It does not check liquidity lock status, owner privileges, token holder concentration, team credibility, or whether the contract can be modified after launch. Always combine Honeypot.is with GoPlus Security, a liquidity lock check, and a holder concentration review before investing.
Final Verdict
Sell restrictions exist because they work. Buyers get excited, skip the checks, and discover the trap only when they try to exit. The tools to avoid this outcome are free, fast, and require no technical background. There is no legitimate reason to skip them.
Start every token research session with Honeypot.is for a quick simulation check, then run GoPlus Security for a full risk breakdown. Add a liquidity lock check and a holder concentration review. If anything raises a flag — stop. There will always be another token. There won’t always be another chance to recover lost capital.
The five minutes it takes to run these checks is the cheapest insurance available in DeFi. Use it every time — especially when you feel most excited about a project. That excitement is exactly what scammers engineer.
