About BlockSec

BlockSec provides comprehensive security solutions for blockchain projects, including smart contract audits, real-time monitoring, and risk prevention tools like Phalcon and MetaSleuth to enhance Web3 security.

blockchain security

BlockSec is a comprehensive Web3 security service provider committed to protecting decentralized applications and blockchain ecosystems through a full-stack approach. Founded by a team of elite security researchers from both academia and industry, BlockSec has established itself as a trusted name in blockchain security auditing, monitoring, and risk mitigation.

By offering an integrated suite of tools — including Phalcon, MetaSleuth, and MetaSuites — BlockSec goes beyond simple audits. It empowers developers, security teams, and protocol operators with real-time threat detection, advanced transaction tracking, forensic analysis, and automated threat response. Its mission is to make Web3 secure, scalable, and transparent through cutting-edge innovation.

BlockSec was established to address critical vulnerabilities and operational security challenges that plague blockchain networks and decentralized applications. While traditional code audits remain essential, BlockSec recognized that real-time risk monitoring, rapid incident response, and dynamic analytics are equally important in safeguarding the evolving landscape of decentralized finance.

Its flagship platform, Phalcon, delivers pre-emptive hack detection by scanning transactions at the mempool level and applying a set of over 200 behavior patterns to flag attacks before execution. Once detected, Phalcon automatically launches countermeasures — including gas-bid transactions — to neutralize the threat before it impacts user funds. This blend of automation and precision makes Phalcon a leader in on-chain threat response.

Complementing Phalcon is MetaSleuth, BlockSec’s cross-chain investigation tool that supports regulatory compliance, forensic analysis, and fund recovery efforts. Through advanced tracing mechanisms, MetaSleuth can link transactions across networks, identify wallet relationships, and unveil potentially illicit behavior even when obfuscated through mixers.

To simplify blockchain security for developers, MetaSuites offers a browser extension with integrated auditing, risk analysis, and developer tools embedded into popular block explorers like Etherscan. MetaSuites dramatically reduces workflow friction while improving insight into contract behavior and historical trends.

BlockSec has delivered audits and live monitoring services for high-profile protocols like Compound, PancakeSwap, Radiant, and Merlin, highlighting its credibility and impact. Its holistic approach to Web3 protection has earned praise from organizations like Forta, Amber Group, and Cobo. With a security-first philosophy, BlockSec stands as a pillar in the decentralization movement, ensuring that protocols remain safe, robust, and reliable.

BlockSec provides numerous benefits and features that make it a standout force in Web3 security:

Real-Time Hack Prevention: Phalcon actively monitors transactions in the mempool, deploying countermeasures against known attack vectors before the transaction reaches the blockchain.
Cross-Chain Forensic Tools: MetaSleuth enables intelligent fund tracking and compliance investigation across multiple networks.
Developer-Friendly Extensions: MetaSuites integrates security and analytics tools into popular explorers, enhancing productivity for developers and analysts.
Customizable Threat Rules: Teams can configure monitoring templates, rules, and thresholds to suit their specific security needs.
High Audit Standards: Comprehensive auditing services provide detailed reporting, issue identification, and expert remediation advice.

BlockSec FAQ

BlockSec Phalcon utilizes mempool-level transaction scanning to detect suspicious behavior before it reaches the blockchain. Once an attack is identified, Phalcon launches a transaction with a gas-bidding strategy that ensures it is processed ahead of the malicious one, effectively blocking the hack. This proactive mechanism offers protocols real-time protection without human intervention. Learn more on Phalcon's page.
Yes, MetaSleuth is designed for cross-chain crypto investigations. It intelligently analyzes transaction trails across 20+ blockchains, helping security teams, compliance officers, and law enforcement track stolen funds or suspicious movements. By mapping wallet interactions and visualizing flows, MetaSleuth offers unmatched precision in forensic tracking. Start exploring at MetaSleuth.
MetaSuites is a browser extension that enhances productivity by embedding security features into popular explorers like Etherscan. Developers can audit contracts, analyze risks, and simulate functions directly from their browser. It simplifies workflows by integrating tools used for DYOR, code audits, and historical reviews. Try MetaSuites on BlockSec’s official site.
Absolutely. Phalcon supports both EOA and multi-sig wallets, enabling protocols to define automated security triggers even in high-authority systems. This includes the ability to block exploits, pause contracts, or send alerts when specific risk conditions are met. This flexibility ensures that even complex governance structures can benefit from BlockSec’s automated security.
Unlike traditional audit firms, BlockSec provides continuous post-deployment monitoring via Phalcon. This ensures that threats like logic flaws, flashloan attacks, or oracle manipulation are caught even after code has gone live. Combined with MetaSleuth’s investigations and MetaSuites’ on-chain tools, projects receive a full-spectrum defense. Learn more at blocksec.com.
