Forta, backed by Andreessen Horowitz (A16z), has launched its new security tool, Forta Firewall, aimed at preventing smart contract exploits. The Firewall offers real-time screening for blockchain protocols and rollups, blocking malicious transactions before they can be executed. This tool is designed to enhance cybersecurity in the Web3 space by integrating into the transaction flow, thus preventing exploits from being executed. Forta claims that the Firewall can detect over 99% of on-chain attacks with fewer than 0.001% false positives, operating in under 50 milliseconds. The FORT token plays a critical role in this system, acting as gas for transactions on the new chain. The launch follows a $23 million funding round in 2021, with support from investors including A16z and Coinbase Ventures. Forta Firewall is also set to be available for vault creators on Euler Finance, allowing for enhanced security measures for users. Additionally, it has formed partnerships with various protocols, including Plume Network, which has over $3 billion in assets.
