Bulk Insert

This feature is used when two or more addContractLog or createContractLog must be contained in a single transaction during the contract life cycle or when more than one contracts are sent as a bulk transaction.

Contents

Name	Description
1. getUnsignedTxAddContractLog	This feature receives the addContractLog transaction creation message.
2. getUnsignedTxCreateContractFile	This feature receives the addContractFile transaction creation message.
3. getGasEstimationSignAndBroadcast	This feature estimates the gas fee required for lining up transaction messages.
4. signAndBroadcast	This feature executes multiple transactions at once.
5. Parameter Description	Parameters required to call API.

1. getUnsignedTxAddContractLog

This function generates addContractLog transactions as messages. Events that happen in a contract life cycle are contained in the addContractLog. Once the gas fee for generating a message is calculated, the transaction is created by the function that executes messages.
&#xNAN;* For a more detailed guide on calculating the gas fee and executing messages, please refer to functions 3 and 4.

    ],
    metaDataJsonString: '"{}"'
  }
}

3. getGasEstimationSignAndBroadcast

This function estimates the gas fee required when generating transactions of the message list created by functions 1 and 2. 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.

Parameters

Name	Type	Example
wallet	Object (FirmaWalletService)	You can check the usage through the "Github example source".
msgList	msgList (EncodeObject[])	1 or 2 "Return value" Array value.

Return value

239964

4. signAndBroadcast
