Fantom to automatically detect smart contract bugs with Watchdog

Quick Take

  • Fantom will leverage an automated system to look for smart contract bugs.
  • The system was developed in partnership with security firm Dedaub.

Fantom has deployed an automated smart contract monitoring system called Watchdog, to strengthen the security of decentralized apps on its blockchain.

Developed in partnership with blockchain security firm Debaub, Watchdog will automatically look for buggy code in smart contracts that could become the root cause of security attacks, Fantom Foundation said in an announcement. It will be particularly focused on attacks plaguing decentralized finance (DeFi) apps.

“We’re incredibly excited to bring a new level of safety and security to the ecosystem with Watchdog,” said Michael Kong, chief executive officer at Fantom Foundation. “Developers require access to cost-effective, efficient, and trustworthy smart contract auditing tools. Watchdog delivers just that, and will set a new standard for security.”

Fantom Foundation said Watchdog will automatically scan for issues across smart contracts in the Fantom ecosystem. Should a vulnerability be detected, security firm Dedaub will notify the project, and assist them in analyzing the risks and support the project team in fixing the vulnerability in time.

The automatic analysis of smart contract logic may not necessarily guarantee protection against attacks as some complex bugs may go undetected. For this reason, Watchdog is aimed at supplementing expensive third-party audits, rather than fully replacing them. 

Even though the DeFi industry has experienced strong growth since 2020, it has seen a corresponding jump in security attacks. The first quarter of 2022 saw $1.3 billion worth of cryptocurrency stolen, 97% of which was stolen from DeFi apps, according to data from the Federal Bureau of Investigation (FBI).
