Frequently Asked Questions

Why is there a need for real-time monitoring with Phalcon even after a code audit has been completed?

icon
Firstly, code audits typically focus on issues of the code within the protocol itself, but the composability of DeFi introduces dependencies on external protocols, which can lead to security issues that are difficult to detect during audits and can result in protocol attacks. Secondly, minor code upgrades and configuration changes by project teams can trigger new security risks. Therefore, real-time monitoring after a project goes live is very important to effectively prevent security risks during its operation.

What sets Phalcon apart from other monitoring services in the market?

icon
  • Speed & Accuracy: Phalcon stands out with swift and precise monitoring, extending beyond on-chain transaction detection to include mempool transactions, contracts, and proposals.
  • Automated Attack Blocking: The platform's automated response system activates immediately during attacks, eliminating the need for manual intervention and significantly reducing potential financial losses.
  • User-Friendly Platform: Phalcon provides an easy-to-use, no-code interface on its SaaS platform, enabling clients to effortlessly set up 24/7 security.
  • Proven Track Record: Prior to its release, Phalcon's technology has been tested in over 20 white-hat interventions, successfully recovering more than $15 million for various projects, demonstrating its reliability and effectiveness.

Can Phalcon conduct automated response actions for protocols managed by multi-sig wallets?

icon
Absolutely. Phalcon supports automated responses for multi-signature managed protocols. You're welcome to sign up and try it out, or book a demo for further details.

Will Phalcon detect attacks originating from private transactions, such as those sent via Flashbot?

icon
  • Firstly, only Ethereum includes privacy transaction services, so attack transactions on other chains can be detected in advance. Secondly, due to anonymity considerations, attackers prefer broadcasting over sending privacy transactions. According to our statistics, only about 3% of losses are through privacy transactions. Last but not least, Phalcon has the ability to early detect attack contracts, which allows it to sense risks in advance and respond automatically.
  • Additionally, even if the first attack transaction is not detected before it is added to the blockchain due to privacy transactions, Phalcon can still take immediate action after the transaction is added to the blockchain, thereby preventing subsequent losses.

With no mempool on Layer 2, how does Phalcon block attacks?

icon
While it's not possible to reverse the initial attack transaction, over 95% of attacks consist of multiple transactions. Phalcon can detect the first transaction and swiftly respond to prevent subsequent ones, effectively preventing further losses.

As a client of Blocksec code audit, am I eligible for a discount on Phalcon?

I run a blockchain and want Phalcon to monitor it for security. How can we get support fast?

icon
You're making a wise decision! Enhancing the security of your chain and its ecosystem can bolster the confidence of LPs and investors, thereby increasing the total value locked (TVL) within your ecosystem. To expedite support, please book a call with us for a rapid assessment.

How do I choose the right Blocksec tool—MetaSuites, MetaSleuth, or Phalcon Explorer—as an on-chain user?

icon
  • MetaSuites is a browser extension designed to enhance on-chain user experience and analytical efficiency. It modifies the UI of blockchain explorers like Etherscan, adding over 20 quick links to common products (e.g., debank, daub, evmstorage), provides access to over 300 million exclusive address tags from BlockSec, and supports transaction explanations with GPT, making it a life-saver for on-chain navigation.
  • MetaSleuth is ideal for analyzing the flow of funds between addresses. It meets the needs of institutional clients for criminal investigation and compliance, and for regular users, it offers insights into the wallets of hackers, whales, and celebrities, revealing hidden patterns and secrets.
  • Phalcon Explorer is a transaction analysis tool tailored for security researchers and developers. Unlike traditional explorers such as Etherscan, Phalcon Explorer reveals more transaction details, such as fund flows, balance changes and traces, and offers simulation and debugging features for in-depth analysis.
