Credshields Blockchain Security provides comprehensive security auditing and testing services for blockchain infrastructure and applications. The service covers security assessments of public blockchains including Bitcoin, Ethereum, and Cosmos, examining critical components such as P2P communication, node security, RPC calls, cryptography, consensus mechanisms, and asset transactions. The service includes threat modeling of the entire blockchain stack, smart contract audits for ERC and custom tokens, wallet and bridge security validation, governance and DAO security reviews, and economic exploit simulations including flash loan attacks and oracle manipulation. The audit process concludes with a final audit report and security certification. The blockchain audit checklist covers eight major categories: node security (data and state storage, database security), node operation (configuration security and optimization), node communication (RPC implementation, P2P protocol security, eclipse and fingerprint attack protection), consensus (algorithm scalability and security), transaction model (privacy, fee mechanisms, congestion attack protection), virtual machine security (implementation logic, sandbox escape, privilege control), account model (storage algorithms, double spending protection), and incentive model (mining algorithm security and ASIC resistance). The service also offers AI-powered scanning capabilities and provides audit results within one week. Credshields has completed over 200 audits and provides direct access to their security team for ongoing support.
