Blockchain Security
Audits & Testing

Credshields has extensive experience researching the security of public blockchains such as Bitcoin, Ethereum, Cosmos, and others and has a deep understanding of the security of crucial modules like P2P communication, node security, RPC calls, cryptography, consensus mechanisms, and asset transactions.

Why It Matters

With threats evolving faster than ever, the cost of weak security can be catastrophic. Strong protection ensures trust, stability, and long-term sustainability for users and businesses.

Blockchain Security

$3B+ lost in blockchain exploits in 2023

Massive financial losses continue to plague the blockchain ecosystem due to security vulnerabilities.

Blockchain Security

One compromised wallet or bridge can affect the entire ecosystem

Interconnected blockchain systems mean a single vulnerability can cascade across platforms.

Blockchain Security

Exchanges and protocols must meet compliance standards for listings

Regulatory requirements demand comprehensive security audits for all blockchain projects.

Our Process

A step-by-step process built to deliver thorough assessments, detailed reviews, and validated results tailored to your security needs.

1

Threat modeling of entire blockchain stack

Comprehensive analysis of all blockchain components and potential attack vectors.

2

Smart contract audits (ERC & custom tokens)

Detailed code review of smart contracts and token implementations.

3

Wallet & bridge security validation

Testing security of wallet integrations and cross-chain bridge protocols.

4

Governance & DAO security reviews

Analysis of governance mechanisms and decentralized autonomous organization structures.

5

Economic exploit simulations

Testing for flash loan attacks, oracle manipulation, and other economic exploits.

6

Final audit & certification

Comprehensive report with findings, recommendations, and security certification.
