Security Features Test Documentation
Overview
This document describes the comprehensive security test suite for ERC-7893, demonstrating how users can protect themselves using the implemented security features.
Test Categories
🔒 Rate Limiting Protection
Purpose: Prevents spam attacks with 5-block cooldown between oracle updates.
Test scenario:
- First update succeeds normally
- Immediate second update fails with “Update too frequent”
- After 6 blocks, normal operation resumes
Real-world protection: Prevents DoS attacks while allowing legitimate operations.
🔒 Access Control Validation
Purpose: Role-based permissions using OpenZeppelin AccessControl.
Test scenario:
- Unauthorized users cannot update data
- Only authorized oracles have ORACLE_ROLE
- Only admins can authorize new oracles
Real-world protection: Prevents unauthorized data manipulation.
🔒 Circuit Breaker Protection
Purpose: Automatic pause when asset values change >20% in one update.
Test scenario:
- Normal state operations work fine
- 30% price drop triggers circuit breaker
- System automatically pauses for protection
Real-world protection: Guards against market manipulation and flash crashes.
🔒 Emergency Control System
Purpose: Guardian-controlled emergency pause capabilities.
Test scenario:
- Only authorized guardian can trigger pause
- All operations blocked during emergency
- Guardian can restore operations
Real-world protection: Rapid response to critical situations.
🔒 DoS Attack Prevention
Purpose: Input validation and bounded operations.
Test scenario:
- Updates with >50 tokens rejected
- Array length mismatches caught
- Gas consumption stays bounded
Real-world protection: Prevents out-of-gas attacks and resource exhaustion.
🔒 Critical Solvency Monitoring
Purpose: Auto-protection when solvency becomes dangerous.
Test scenario:
- System monitors ratio continuously
- Critical alerts below 102% threshold
- Automatic pause at dangerous levels
Real-world protection: Prevents protocol insolvency.
🔒 Oracle Staleness Detection
Purpose: Flags data older than 1 hour.
Test scenario:
- Fresh data correctly identified
- Stale data (>1 hour) flagged
- Transparency about data freshness
Real-world protection: Prevents decisions based on outdated information.
🔒 Historical Data Rate Limiting
Purpose: Prevents spam entries in historical data with MIN_ENTRY_INTERVAL (1 hour) and bounds storage with MAX_HISTORY_ENTRIES (8760 entries ~1 year).
Test scenario:
- Rapid updates only create one historical entry per hour
- Historical storage is bounded to prevent unbounded growth
getHistoricalDataInfo()provides transparency about storage limits
Real-world protection: Prevents storage spam attacks and ensures predictable gas costs for historical queries.
🔒 Multi-Oracle Consensus
Purpose: Price validation across multiple sources.
Test scenario:
- Consensus when oracles agree (within 5%)
- Consensus fails during manipulation attempts
- Resistant to single-oracle attacks
Real-world protection: Guards against oracle manipulation.

Running the Tests
To execute these security tests in a development environment:
# Install dependencies
npm install
# Compile contracts
npx hardhat compile
# Run security tests
npx hardhat test test/SecurityFeatures.test.ts
# Run all tests
npx hardhat test
The tests demonstrate real protection scenarios and validate that all security mechanisms work as intended for production use.
Security Test Results
Security Features Status Summary
Real-time security features status showing all 8 protection mechanisms active and operational, including access control, rate limiting, DoS protection, circuit breaker, emergency controls, oracle staleness detection, price validation, and historical data management.
Security Parameters Configuration
Production-validated security parameters with their real-world values: 5% max price deviation, 50 token limit, 1-hour staleness threshold, 20% circuit breaker, and 5-block rate limiting for optimal protection.
These screenshots demonstrate that all security features are properly implemented and working together to provide comprehensive protection for users of the ERC-7893 standard.
