# Testnet Security Checks

> Pre-deployment validation and testing on testnets

# Testnet Security Checks

Validate your smart contracts' security on testnets before mainnet deployment. BevorAI provides comprehensive testnet analysis to identify vulnerabilities, test attack scenarios, and ensure your contracts are production-ready.

<Tip>
  Building a chain or testing deployed contracts? Paste a contract address into the <a href="https://app.bevor.io">Dashboard</a> to analyze instantly. Chain builders can also schedule cron jobs to scan their network using the <a href="/api-reference/introduction">API Reference</a>.

## Pre-Deployment Validation

### Comprehensive Security Analysis

**Full Contract Suite Scanning**

```bash theme={null}
# Analyze entire project before deployment
bevor scan-testnet \
  --network goerli \
  --project ./contracts \
  --include-tests \
  --economic-analysis \
  --formal-verification

# Focus on deployment-specific issues
bevor validate-deployment \
  --network goerli \
  --contracts ./contracts \
  --deployment-script ./scripts/deploy.js \
  --check-initialization
```

**Deployment Script Analysis**

* Analyze deployment and initialization scripts
* Verify proper access control setup
* Check for deployment-time vulnerabilities
* Validate configuration parameters

### Attack Simulation

**Automated Attack Testing**

```bash theme={null}
# Simulate common attacks on testnet
bevor attack-sim \
  --contract 0x1234...abcd \
  --network goerli \
  --attacks reentrancy,front-running,oracle-manipulation \
  --funding 10ETH

# Custom attack scenarios
bevor attack-sim \
  --contract 0x1234...abcd \
  --scenario ./attack-scenarios/custom-exploit.js \
  --network goerli
```

**Attack Scenarios Tested**

* **Reentrancy Attacks**: Classic and cross-function reentrancy
* **Front-Running**: MEV exploitation and sandwich attacks
* **Oracle Manipulation**: Price feed attacks and flash loan exploits
* **Governance Attacks**: Vote buying and proposal manipulation
* **Economic Exploits**: Arbitrage and liquidity manipulation

### Integration Testing

**Multi-Contract Interaction Analysis**

```bash theme={null}
# Test protocol-wide interactions
bevor test-integration \
  --network goerli \
  --protocol-config ./config/protocol.json \
  --test-scenarios ./tests/integration \
  --economic-simulation
```

**Third-Party Integration Security**

* Test interactions with existing DeFi protocols
* Validate oracle integrations and dependencies
* Analyze cross-chain bridge interactions
* Verify external contract assumptions

## Continuous Testnet Monitoring

### Automated Monitoring Setup

**Testnet Deployment Monitoring**

```javascript theme={null}
// Configure continuous testnet monitoring
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
    }
  }
};

bevor.monitor.configure(monitoringConfig);
```

**Performance Benchmarking**

* Monitor gas usage patterns
* Track transaction success rates
* Analyze user interaction patterns
* Measure economic efficiency metrics

### Regression Testing

**Security Regression Detection**

```bash theme={null}
# 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 \
  --previous-deployment 0xold...contract \
  --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**

```bash theme={null}
# 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**

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

## Integration with Development Workflow

### Feature Branch Testing

**Branch-Specific Analysis**

```yaml theme={null}
# Feature branch security validation
feature-security:
  runs-on: ubuntu-latest
  if: startsWith(github.ref, 'refs/heads/feature/')
  
  steps:
  - uses: actions/checkout@v4
  
  - name: Deploy to Feature Testnet
    run: |
      npm run deploy:feature-testnet
      echo "FEATURE_CONTRACT_ADDRESS=$(cat .deployed-address)" >> $GITHUB_ENV
      
  - name: BevorAI Feature Analysis
    run: |
      bevor analyze-feature \
        --contract $FEATURE_CONTRACT_ADDRESS \
        --network goerli \
        --feature-branch $GITHUB_REF_NAME \
        --compare-to main
```

### Release Validation

**Pre-Release Security Certification**

```bash theme={null}
# Comprehensive pre-release validation
bevor certify-release \
  --version v2.1.0 \
  --contracts ./contracts \
  --network goerli \
  --requirements ./security/requirements.yml \
  --generate-certificate
```

**Release Security Checklist**

## Automated Testing Integration

### Security Test Generation

**Automated Test Creation**

```javascript theme={null}
// BevorAI generates security tests based on analysis
const securityTests = await bevor.generateTests({
  contract: '0x1234...abcd',
  network: 'goerli',
  testTypes: [
    'reentrancy',
    'access-control',
    'economic-attacks',
    'edge-cases'
  ],
  framework: 'hardhat' // or 'foundry', 'truffle'
});

// Integrate with existing test suite
securityTests.forEach(test => {
  describe(`Security Test: ${test.name}`, () => {
    it(test.description, test.testFunction);
  });
});
```

### Continuous Security Testing

**Scheduled Security Validation**

```yaml theme={null}
# Daily comprehensive security check
schedule-security-check:
  schedule:
    - cron: '0 6 * * *'  # Daily at 6 AM UTC
    
  jobs:
    comprehensive-security:
      runs-on: ubuntu-latest
      steps:
      - name: Comprehensive Testnet Analysis
        run: |
          bevor comprehensive-analysis \
            --network goerli \
            --all-deployed-contracts \
            --include-economic-simulation \
            --generate-trends-report
```

## Best Practices

### Testnet Strategy

1. **Progressive Validation**
   * Start with unit-level security testing
   * Progress to integration security testing
   * Finish with full protocol stress testing
   * Validate under various network conditions

2. **Realistic Simulation**
   * Use production-equivalent configurations
   * Test with realistic economic parameters
   * Simulate actual user behavior patterns
   * Include adversarial testing scenarios

3. **Documentation and Evidence**
   * Document all security testing procedures
   * Maintain evidence of security validation
   * Create security testing reports for auditors
   * 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
