spark_flashnet_createCPPool

This method is coming 🔜

Use the spark_flashnet_createCPPool method to request the creation of a Constant Product (CP) liquidity pool on Flashnet directly from the user’s Spark wallet.

Your app provides the pool parameters (assets, fees, namespace, etc.), and the wallet handles the signing and submission to Flashnet.
