Phylax and Titan Partner to Deploy Application-Level Circuit Breakers on Ethereum

Phylax has partnered with Ethereum block builder Titan to introduce block-level circuit breakers designed to safeguard decentralized finance protocols against exploits. The integration allows applications to establish custom operational rules, such as capping single withdrawals at 50% of vault assets, which Titan enforces by filtering out non-compliant transactions during block construction. Titan accounted for approximately 53% of externally built Ethereum blocks accepted by validators over a recent 24-hour period. Initial rollout partners Lighter and Derive have placed nearly $1 billion under the protective system, which currently relies on builder trust rather than cryptographic proofs.
