+You are an expert in blockchain security and MEV bot development. I'm building an MEV bot in Go that needs to be secure against various attack vectors.
+
+I need help with:
+
+1. Protecting private keys and signing credentials
+2. Preventing frontrunning by other bots
+3. Securing RPC endpoint connections
+4. Handling MEV submission securely
+5. Preventing sandwich attacks
+6. Implementing secure configuration management
+
+Please provide production-ready Go code that:
+- Implements secure key management practices
+- Protects against common MEV bot vulnerabilities
+- Handles sensitive data securely
+- Follows security best practices
+- Includes comprehensive comments
+
+The code should:
+- Store private keys securely using hardware wallets or secure enclaves
+- Use encrypted connections for RPC endpoints
+- Implement proper access controls
+- Handle errors without exposing sensitive information
+- Include security checks and validations
