const monitoringConfig = {
  network: 'goerli',
  contracts: [
    '0x1234...contract1',
    '0x5678...contract2'
  ],
  monitoring: {
    realTime: true,
    alerts: ['critical', 'high'],
    webhooks: ['https://your-webhook.com/alerts'],
    analysis: {
      transactions: true,
      stateChanges: true,
      economicMetrics: true,
      gasAnalysis: true
    }
  }

Regression Testing

Security Regression Detection

# Compare security posture across versions
bevor compare-versions \
  --baseline v1.0.0 \
  --current v1.1.0 \
  --network goerli \
  --focus security-regressions

# Automated regression testing in CI
bevor regression-test \

  --current-deployment 0xnew...contract \
  --network goerli \
  --test-suite ./tests/security

Testnet-Specific Security Considerations

Environment Differences

Testnet vs Mainnet Risks

• Reduced Economic Incentives: Lower value attacks may not be tested
• Different User Behavior: Testing patterns vs real usage
• Network Conditions: Different congestion and gas price dynamics
• Oracle Reliability: Testnet oracles may have different characteristics

Mitigation Strategies

• Simulate mainnet economic conditions
• Test with realistic transaction volumes
• Use production-equivalent oracle configurations
• Analyze worst-case network scenarios

Realistic Testing Scenarios

Economic Stress Testing

# Simulate high-value scenarios
bevor stress-test \
  --contract 0x1234...abcd \
  --network goerli \
  --scenario high-tvl \
  --simulate-value 100M USD \
  --attack-budget 10M USD

Network Congestion Testing

# Test under congestion conditions
bevor congestion-test \
  --contract 0x1234...abcd \
  --network goerli \
  --gas-price-range 50-500 \
  --block-time-variance 2x \
  --mempool-simulation

   • Track security improvements over time

Risk Management

Testnet Risk Assessment

• Evaluate testnet-specific security risks
• Consider differences from mainnet environment
• Plan for mainnet-specific validation
• Prepare incident response procedures

Validation Coverage

• Ensure all critical paths are tested
• Validate all external integrations
• Test upgrade mechanisms thoroughly
• Verify economic model assumptions
