  }
}

2. getGasEstimationFromEncodeObject

This function estimates the gas fee required when generating transactions of the message list created by function 1. When using Bulk Insert, there is a high chance where the gas fee could exceed the default gas fee(0.02fct). Therefore, prior to the execution of the transaction, the gas fee must be estimated properly.

msgList	Array(NftTxClient.msgMint)	[ data1, data2, data3 ]
