RPC Node and API Endpoint Security Testing

Infrastructure-level penetration testing of your blockchain RPC nodes, indexer APIs, and archival services to prevent denial-of-service and data integrity attacks.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.

  • Protocols & Standards: ERC-20, ERC-721, ERC-1155, ERC-4626, and custom logic.
  • Key Deliverables: Full test suite, deployment scripts, technical documentation, and post-launch monitoring.
  • Typical Outcome: A secure, auditable contract suite deployed to mainnet in 2-4 weeks.

We don't just write code; we engineer the financial and operational logic that powers your business, with a focus on long-term maintainability and regulatory foresight.

Comprehensive Infrastructure Security Assessment

Our security assessment goes beyond standard penetration testing to deliver a holistic audit of your RPC node and API endpoint security posture, identifying vulnerabilities before they become exploits.

01

Full-Stack Node Security Audit

In-depth analysis of your node software (Geth, Erigon, Besu), configuration files, and network settings. We identify misconfigurations, outdated dependencies, and insecure RPC methods to prevent unauthorized access and data leaks.

02

API Endpoint & Rate Limiting Review

Assessment of your JSON-RPC/WebSocket endpoints for injection attacks, DDoS vulnerabilities, and improper access controls. We validate your rate-limiting logic and WAF rules to ensure resilience against abuse.

Why Our Approach is Different

Chainscore RPC Security Testing vs. Generic Scans

Generic security tools scan for known vulnerabilities. Chainscore's RPC and API endpoint testing simulates real-world attacks to expose critical infrastructure risks that automated scanners miss.
