# Testing Integration

**Importance of Running Test Transactions on Mainnets**

1. **Real Environment Validation**

* Mainnets provide the most realistic testing scenarios
* Validates actual fund flows and contract interactions
* Ensures all functionalities work properly in production

2. **Testnet Limitations**

* Most bridges and exchanges have limited testnet support
* Extremely low liquidity makes effective testing difficult
* Testnet environments may differ from mainnet

3. **Mainnet Advantages**

* Full liquidity support
* 100% functionality availability
* Direct validation of actual economic models

4. **Testing Recommendations**

* Start with small amounts for initial verification
* Gradually scale up testing volume
* Monitor all transaction statuses

5. **Important Notes**

* Ensure contracts have been audited
* Set appropriate gas limits
* Maintain complete transaction records

We strongly recommend conducting all integration tests on mainnets as this represents the best practice for ensuring system stability and functional integrity.

To minimize costs, we recommend testing on chains with low gas fees. Optimism and other Layer 2 (L2) chains are excellent choices for cost-effective testing.
