# Maker-Checker System

## What is Maker-Checker?

The Maker-Checker (Four-Eyes Principle) is a critical security control mechanism designed to enhance financial transaction safety and prevent unauthorized or fraudulent transactions. It introduces a two-step verification process for sensitive financial operations.

## Transaction Lifecycle

```mermaid theme={"system"}
stateDiagram-v2
    [*] --> Initiated : Maker Creates
    Initiated --> Pending : Submit for Approval
    Pending --> Approved : Checker Approves
    Pending --> Declined : Checker Declines
    Approved --> Processed
    Declined --> [*]
    Processed --> [*]

    state Processed {
        [*] --> Completed
        Completed --> [*]
    }
```

1. **Initiation (Maker)**

   * Create transaction
   * Submit for approval
   * Transaction status: Pending

2. **Review (Checker)**

   * Examine transaction details
   * Options:
     * Approve transaction
     * Decline transaction

3. **Outcome**
   * Approved: Transaction processed
   * Declined: Transaction rejected
   * Pending: Awaiting review

## Best Practices

1. **Segregation of Duties**

   * Makers cannot approve their own transactions
   * Checkers must be different from makers

2. **Security Measures**
   * Implement multi-factor authentication
   * Maintain comprehensive audit logs
   * Regularly review role assignments

## Troubleshooting

* **Transaction Stuck**: Contact system administrator
* **Permission Issues**: Review role configuration
* **Approval Delays**: Check checker availability
