Strengthening the Web3 Security Defense: How Caldera Uses Cryptographic Auditing to Resist Zero-Day Attacks?

In the Web3 field, zero-day attacks and asset security remain core challenges for ecological development, and Caldera has built a solid barrier with a layered security system for a total locked value (TVL) of $1 billion. Its security model deeply integrates advanced cryptographic technology, using BLS signatures to ensure the security and efficiency of validator consensus, while utilizing ECDSA for transaction verification, ensuring the compliance and traceability of every operation.

In response to the centralized risks of sorters identified in the threat model, Caldera has innovatively launched a progressive decentralization plan, gradually dispersing the permissions of core nodes to fundamentally reduce the probability of single points of failure. To further enhance privacy protection, ZK-SNARKs technology has entered the development stage, which will provide stronger encryption protection for user data and transaction information in the future.$ERA

At the level of security auditing, the globally renowned security company Trail of Bits conducted a comprehensive review of Caldera's smart contracts in June 2025, finding no critical security issues, fully validating the reliability of its code. The audit scope also extended to the Metalayer relayer, eliminating the risk of data tampering through strict verification of message integrity. In addition, Caldera has established a comprehensive incident response mechanism, utilizing the Sentry system to trigger automatic alerts, combined with a 24/7 uninterrupted team rotation system, ensuring that any abnormal situation can be detected and handled promptly.#caldera

In the face of common DDoS attacks, Caldera effectively resists traffic impacts and ensures stable network operation through a dual strategy of integrating Cloudflare protection services and limiting RPC call frequencies. In the optimistic rollup mechanism, it has set a seven-day challenge period for fraud proof and uses $ERA bonds as a guarantee, adding an extra layer of protection for ecological asset security.@Caldera Official

In response to the industry pain point of bridging vulnerabilities, Caldera adopts an intention-based design concept, completely avoiding asset custody issues and eliminating security risks during the bridging process from a mechanism perspective. At the same time, a rigorous response protocol has been established, allowing for rapid cessation of on-chain operations upon detection of abnormal situations, and data rollback via Ethereum snapshots to minimize losses. To address future security threats, Caldera also plans to complete cryptographic upgrades by 2026, achieving post-quantum resistance.
