Linea, Consensys' Layer 2 scaling solution, has integrated Credible Layer security technology to enhance smart contract protection. This innovative framework, inspired by traditional financial market circuit breakers, allows for real-time monitoring and selective intervention in smart contract operations. Developed in collaboration with security startup Phylax, the system can pause suspicious transactions while permitting legitimate ones, offering a proactive defense against exploits. The implementation has already been adopted by several Linea-based applications, including Euler, Etherex, and Turtle Club, showcasing its versatility across decentralized finance sectors. Credible Layer's architecture involves continuous monitoring and machine learning algorithms to detect anomalies, providing a robust security layer without significant performance impact. This advancement positions Linea as a leader in blockchain security, potentially setting a new industry standard for Layer 2 networks.
