Blockchain Security Assessment & Smart Contract Audit

Rivanorth's Blockchain Security Assessment is a comprehensive offensive security service delivering full-spectrum, defence-in-depth security for Web3 projects. The service applies an ethical hacker mindset to identify and remediate vulnerabilities across smart contracts, decentralised applications, blockchain infrastructure, and APIs before they can be exploited.

Smart Contract Audit

Manual and automated review of smart contract code to identify vulnerabilities including reentrancy attacks, integer overflows, access control flaws, logic errors, and other exploit vectors. Smart contracts are immutable once deployed — vulnerabilities cannot be patched like traditional software, making pre-deployment security review critical. Rivanorth's work has been featured in Rekt and Blockchain Threat Intelligence publications, reflecting industry-recognised expertise.

dApp & Web3 Penetration Testing

Security testing of decentralised applications from a hacker's perspective, covering front-end interfaces, blockchain integrations, and Web3 APIs. Targeted API penetration testing identifies authentication flaws, injection vulnerabilities, and data exposure issues in APIs used by blockchain applications.

L1 and L2 Blockchain Audit

Security review of Layer 1 and Layer 2 blockchain implementations, covering consensus mechanisms, node security, and protocol-level vulnerabilities.

On-Chain Monitoring and Investigations

Ongoing surveillance of on-chain activity to detect anomalous behaviour, potential exploits in progress, and support post-incident forensic analysis.

Deliverable

Findings are delivered in a comprehensive, clear, and actionable report with prioritised remediation guidance. Notable clients include TempleDAO / Origami Finance (DeFi protocol), which received a comprehensive and actionable assessment identifying key defence-in-depth improvements.
