MemePolice is a decentralized application (dApp) designed to analyze the risk associated with memecoins. It leverages data from the Ethereum blockchain and performs advanced calculations to provide a detailed risk score based on various metrics such as price, market cap, volume, transaction activity, and holder concentration.

With the rise of memecoins in the cryptocurrency market, investors face an increasing need for tools to assess the associated risks. MemePolice analyzes memecoin data on the Ethereum blockchain and computes a detailed risk score. This score helps users make informed decisions about whether to invest in or trade a specific token.
-
High Volatility and Risks in Memecoins: The memecoin market is known for its extreme volatility. While some memecoins have gained immense popularity and value (e.g., Dogecoin, Shiba Inu), many others are highly speculative, with little utility or backing. Investors are often drawn into these projects due to social media hype without fully understanding the risks. Memecoin Police provides a way to mitigate these risks by giving users a full breakdown of each token's potential vulnerabilities.
-
Rise in Fraud and Scams: The anonymity of blockchain technology has given rise to countless scams and rug-pulls, particularly in the memecoin market. Unscrupulous developers launch tokens with the intent to defraud investors by quickly selling off large portions of the supply or manipulating token prices. Memecoin Police addresses this by identifying high-risk tokens before users invest.
-
Vitalik Buterin's Vision: The project is inspired by Vitalik Buterin's concept of using memecoins for charitable or positive-sum causes. He proposed that rather than creating worthless or harmful memecoins, the crypto community could develop coins that provide real value, such as charity coins or fun, engaging games that leave communities better off. Memecoin Police aligns with this vision by promoting transparency and ensuring that users engage with memecoins that have safer and more meaningful purposes. Link
- Comprehensive Risk Scoring: Calculates a detailed risk score based on multiple factors, such as price volatility, market cap, trading volume, holder concentration, transaction volume, and contract age.
- Attestation with Sign Protocol: Leverages Sign Protocol to authenticate and secure the analysis results on the Ethereum blockchain.
- Dynamic Visualization: Presents the risk analysis visually using a radar chart for easy interpretation of each factor's contribution to the overall risk score.
The risk scoring model in MemePolice evaluates multiple parameters. Here's how the score is computed:
MemePolice utilizes a multifaceted approach to risk evaluation, leveraging statistical methods and advanced mathematical modeling. Here's a breakdown of how the overall risk score is computed:
-
Price Volatility:
- Logarithmic Scaling to smoothen the impact of extreme price fluctuations. Lower token prices yield higher risk values.
-
Market Cap Stability:
- An Exponential Decay Function is applied to reduce risk for larger market caps, showcasing the diminishing returns of increased capitalization on risk reduction.
-
Volume Liquidity:
- Risk inversely correlates with volume, modeled using a Square Root Function, accounting for the diminishing influence of very high volumes.
-
Holder Concentration:
- The Holder Concentration Risk uses a Quadratic Function to penalize high token concentration among a few holders, amplifying the risk in cases of potential manipulation.
-
Transaction Activity:
- A Logistic Growth Model analyzes transaction data, wherein fewer transactions increase the risk score due to reduced liquidity and market participation.
-
Contract Age:
- Exponential Decay over time is used to reduce the risk for older contracts, accounting for reduced vulnerability with age.
To visualize how these parameters affect the overall score, MemePolice uses a Radar Chart for an intuitive representation. Each risk category—Price, Market Cap, Volume, Holder Concentration, Transactions, and Contract Age—is plotted on an axis to show its contribution to the final score.
- Logarithmic Functions smoothen price data, adjusting for extreme token values.
- Exponential Decay minimizes risk from larger market caps and older contracts.
- Quadratic Penalization for holder concentration ensures fairness in assessing the risk of market manipulation.
MemePolice integrates with Sign Protocol to securely store attestations and risk scores on the blockchain. This integration ensures transparency, immutability, and integrity in the risk analysis process. Here's how it works:
Each attestation follows a specific schema:
const schemaId = "0x1e3"; // Unique identifier for the attestation schemaWith the rise of memecoins, many tokens are speculative and prone to scams or harmful ideologies. MemePolice helps protect users by providing detailed risk analysis, ensuring informed investment decisions. Inspired by Vitalik Buterin's concept of charity coins and Robin Hood games, this tool is designed to encourage transparency in the chaotic world of memecoins.
Our mission is to assess the risk of speculative tokens, protect crypto enthusiasts, and promote a healthier, more sustainable crypto ecosystem.
The total risk score is the Weighted Sum of all the components, normalized between 0 and 100 using Min-Max Normalization.
By employing this mix of statistical and algebraic models, MemePolice ensures a robust analysis, safeguarding users from highly speculative or potentially fraudulent memecoins.
MemePolice uses the following technologies:
- Ethereum: Blockchain platform for decentralized transactions and data storage.
- Sign Protocol: Framework for attestations and securing data on-chain.
- Ethers.js: JavaScript library for interacting with the Ethereum blockchain.
- Next.js: React framework used to build the dApp's frontend.
- Alchemy: Ethereum API provider for retrieving blockchain data.
