Token Sniffer Comprehensive Guide & Review

Crypto tokens, particularly the meme coin sector, is rife with scams.Tools like Token Sniffer offer valuable insights but should be complemented with community engagement and additional research tools to navigate this ever-evolving landscape.

As the space grows, so does the creativity of scammers, who often deploy innovative tactics to exploit unsuspecting investors. This guide dives deep into using Token Sniffer effectively, understanding its features, and incorporating other best practices to avoid falling victim to crypto scams.


TokenSniffer is a platform designed to assess the safety of crypto tokens. By analyzing a token’s smart contract, liquidity, holder distribution, and other factors, it assigns a safety score that can serve as a starting point for your research.

Key Features of TokenSniffer

  • Contract Address Analysis: Input a token’s contract address to receive a safety score.
  • Swapability Check: Confirms whether a token can be bought and sold on decentralized exchanges.
  • Liquidity Analysis: Evaluates the availability and lock status of liquidity.
  • Holder Distribution: Identifies concentration of holdings among wallets.
  • Bubble Map: A visual representation of token transfers to detect suspicious patterns.

Pro Tip: Even a perfect score (100/100) on TokenSniffer doesn’t guarantee success. Always Do Your Own Research (DYOR).

Why Research is Crucial in the Meme Coin Casino

The crypto space, especially meme coins, is a breeding ground for innovation—but also for scams. Fraudulent actors continually evolve their tactics to deceive investors. As the saying goes, “The most creative and the most innovative people in the space are the scammers.” This makes due diligence a critical skill for anyone venturing into the crypto world. Tools like Token Sniffer provide a critical layer of analysis, helping investors assess potential risks.

Common Risks in Meme Coins

  1. Honeypot Scams: Tokens that appear legitimate but prevent selling after purchase.
  2. Rug Pulls: Developers withdraw liquidity, leaving token holders with worthless assets.
  3. Mutable Metadata: Code that can be altered post-deployment to introduce malicious behaviors.

While tools like TokenSniffer help identify risks, they are not foolproof. Scammers innovate constantly, and no tool can guarantee safety.


Step-by-Step Guide to Using TokenSniffer

1. Obtain the Token Contract Address

Start by finding the token’s contract address from the block explorers or from platforms like DEX Screener. This address uniquely identifies the token on its respective blockchain. Here is an example of the block explorer view for the “Department Of Government Efficiency” that became trendy recently.

2. Input the Contract Address into TokenSniffer

  • Navigate to TokenSniffer.
  • Paste the contract address into the search bar.
  • Review the token’s safety score and detailed analysis.

3. Review Key Metrics

To understand Token Sniffer criteria, here is an overview and explanation of key metrics based on the LUM token example.

Swapping Ability & Contract Code:

At the time of writing, the token is sellable and not a honeypot according to Token Sniffer. Buy and sell fees are both 0%, which is below the safe threshold of 5%. In that case, Token Sniffer checks if the token can be bought and sold, as well as if it detects malicious code that could block sell transactions (i.e. honeypot detection). This is important to ensure investor safety as malicious tokens may allow buying, but not selling of tokens, which leads to the funds being trapped indefinitely.

Additionally, the contact source code is verified. Ownership is renounced, or no ownership functions are present. Meaning the creator does not have special permissions, or centralized power over token activity.

The check that takes place here is to see whether the code is publicly displayed through the source code being verified on a block explorer. Plus, checking for the presence or absence of special permissions to alter contract functions or drain liquidity.

This is important because it ensures that unauthorized changes to the contract do not occur, reducing the risk of rug pulls or contract manipulation.

Mutable Metadata

  • Analysis: The contract does not contain mutable metadata. This reduces the likelihood of post-deployment changes that could introduce honeypot features or other malicious elements.
  • Checks Performed:
    • Scanning for fields in the contract that allow metadata modifications post-deployment.
  • Why It’s Important: Fixed metadata ensures transparency and prevents unforeseen alterations that could compromise the token’s integrity.

Holder Analysis: 

Assess whether token holdings are concentrated among a few wallets, which can indicate a risk of manipulation. In the LUM token example, the creator wallet holds less than 5% of the circulating supply. No single holder possesses more than 5%.

The check performed is an evaluation of token distribution to identify centralization risks, as well as mapping of token holders to ensure no single entity has disproportionate control over the total supply, which could significantly impact price movements. Token Sniffer simplifies the visualization of these criteria through the Bubble Maps feature.

Liquidity Analysis:

Verifies if token liquidity on a DEX is locked for a reasonable duration. The LUM token has adequate liquidity on UniSwap v3 (136.41 ETH and 4,930.57 USDC at a 1% fee tier at the time of writing). However, less than 95% of liquidity is burned or locked for at least 15 days, meaning significant liquidity can be removed by the liquidity provider, posing a rug pull risk.

Checks Performed:

  • Assessment of liquidity adequacy across supported decentralized exchanges.
  • Analysis of initial and locked liquidity.
  • Examination of liquidity ownership by the creator.

Why It’s Important: Adequate and locked liquidity ensures smooth trading and prevents the removal of liquidity that could lead to price manipulation or a rug pull.

Summary of Key Risks Identified for LUM Token

  • While the token has adequate liquidity for trading, the lack of locked liquidity poses a risk of rug pulls.
  • Positive attributes include renounced ownership, fair holder distribution, and the absence of malicious code.

Investors are advised to weigh these factors carefully alongside additional research.

Summary of Criteria:

  • Swapping Ability: Verifies whether the token can be freely bought and sold.
  • Honeypot Detection: Checks for malicious code that prevents selling the token.
  • Contract Analysis: Highlights red flags in the smart contract.
  • Holder Analysis: Evaluates token distribution among holders and the adequacy of liquidity.
  • Liquidity Analysis: Ensures adequate liquidity for trading and verifies whether a significant portion is locked to prevent rug pull risks.
  • Mutable Metadata: Identifies whether the token’s metadata can be altered post-deployment, which could enable scams like honeypots or rug pulls.

Key Features of Token Sniffer

Bubble Map Visualization

Token Sniffer’s Bubble Map provides a visual representation of token transfers between wallets, allowing for deeper analysis of relationships and potential red flags.

Key elements of the map include:

  • Orange Bubbles: Represent the creator’s address.
  • Red Bubbles: Indicate burn addresses.
  • Blue Bubbles: Depict the top holders’ wallets.

Each bubble is linked to a blockchain explorer, enabling users to verify transaction histories and further analyze wallet activities.

Smart Contract Code Access

Token Sniffer allows users to view a token’s smart contract code. While not everyone is technically skilled enough to interpret the code, you can copy and paste it into tools like ChatGPT to check for potential issues.

Additional Red Flags:

  • Honeypots: A common scam where investors can buy but not sell tokens. Sites like Honeypot.is can help identify these scams.
  • Mutable Metadata: While not inherently malicious, this feature allows changes to the token after deployment, which could lead to scams.

Additional Tips:

  • Exercise Caution with New Tokens: Recently deployed tokens may carry higher risks; thorough research is essential before investing.

Understanding the Limitations

Even the most advanced tools, including Token Sniffer, have limitations. As one expert puts it, “Just because it’s not a honeypot now does not mean it won’t become one in the future.” The mutable nature of smart contracts and metadata means that scams can be implemented long after a token’s launch. Therefore, continuous monitoring and vigilance are essential.

Disclaimer: No tool can guarantee complete safety, and the cryptocurrency landscape is continually evolving. It’s crucial to stay informed and exercise due diligence when investing.

While Token Sniffer is a valuable tool, it has its limitations:
