Security-focused transaction explorer and debugger from BlockSec
Last updated: July 2026
Phalcon Explorer, built by the security firm BlockSec, is a transaction explorer purpose-built for security analysis and debugging rather than everyday lookups. It provides an in-depth, visual breakdown of EVM transactions oriented toward understanding attacks, exploits, and complex DeFi interactions: full call traces, decoded internal calls, balance-change summaries, state diffs, and fund-flow visualizations that make it possible to reconstruct exactly how a hack drained a protocol or how a complex arbitrage executed. Security researchers, auditors, and DeFi developers use Phalcon to dissect exploit transactions, understand MEV, and debug their own contracts' behavior with far more clarity than a standard explorer offers. It complements BlockSec's broader security stack (attack monitoring and interception), and it supports major EVM chains. The core explorer is free to use, which has made it a staple in post-mortem write-ups of DeFi hacks across the industry. The considerations: it's specialised for security and debugging, so it's overkill for someone who just wants to confirm a transfer, it's EVM-only, and getting full value from it assumes familiarity with how EVM calls, traces, and DeFi mechanics work. But for anyone doing security research, incident analysis, or serious transaction debugging, Phalcon Explorer is one of the sharpest tools available and a standard reference in the security community.
