In May 2025, Cetus Protocol, a decentralized exchange (DEX) on the Sui blockchain, reported a devastating exploit that drained over $200 million from its liquidity pools. This high-profile incident underscores a critical truth: robust blockchain monitoring tools are no longer optional—they are essential for detecting suspicious transactions, tracking fund flows, and maintaining security across decentralized networks.
As blockchain ecosystems grow more complex, the need for advanced analytical tools has surged. Whether you're a developer, investor, or security analyst, understanding where funds move, who controls large wallets, and how protocols behave in real time is crucial. This article explores the top 10 blockchain monitoring tools that empower users with deep visibility into on-chain activity.
Bitquery’s Moneyflow: Visualizing Fund Flows with Ease
Moneyflow by Bitquery is a powerful blockchain analytics tool designed to visualize and monitor fund movements across chains. With an intuitive interface, it makes complex transaction data accessible—even to non-technical users.
Key Features:
Transaction Visualization
Moneyflow maps out fund transfers between addresses using interactive graphs, revealing hidden patterns in large datasets that raw transaction logs often obscure.
Peel Chain Analysis
This feature traces large sums broken into smaller transactions—commonly used to obfuscate illicit activity—helping investigators uncover the true origin of funds.
Entity Recognition
The platform identifies and labels wallet types such as centralized exchanges, DeFi protocols, or known malicious actors, improving accuracy in threat detection.
Multi-Chain Support
Moneyflow supports Ethereum, Arbitrum, BSC, and other EVM-compatible chains, offering broad coverage for cross-chain analysis.
Transaction & Address Monitoring
Users can input specific hashes or addresses to trace fund movement across 10+ transaction layers. Historical trends, associated wallets, and balance changes are all visible for proactive surveillance.

Chainalysis: The Industry Standard in Blockchain Forensics
Chainalysis is one of the most widely adopted blockchain intelligence platforms, trusted by governments, exchanges, and financial institutions worldwide.
How It Works:
- Public Chain Data Collection: Aggregates all publicly available transaction data including timestamps, amounts, and token types.
- Address Clustering: Uses machine learning to group addresses likely controlled by the same entity.
- Entity Tagging: Leverages partnerships with exchanges to label addresses accurately.
- Risk Scoring: Assigns risk levels to transactions based on behavioral patterns linked to money laundering, scams, or darknet markets.
Chainalysis excels in compliance and forensic investigations, making it indispensable for regulatory adherence and fraud prevention.

Nansen is ideal for traders seeking alpha through behavioral analytics and macro-level chain activity.
Dune: Query-Driven Blockchain Analytics
Dune Analytics empowers users to create custom queries and dashboards for blockchain data exploration.
Why Dune Stands Out:
- Web Application: Offers a collaborative environment for building visualizations and sharing insights.
- Extensive Data Catalog: Includes raw, decoded, and abstracted tables across multiple blockchains.
- Dune API: Enables developers to integrate live blockchain data into external applications.
- Query Engine: Built specifically for blockchain analysis with specialized functions for timestamps, contracts, and token transfers.
- Alerts System: Sends email or webhook notifications when predefined query conditions are met.
Dune is perfect for analysts who want full control over their data pipelines.
