This feature estimates the gas fee required for lining up transaction messages. | |
This feature executes multiple transactions at once. | |
Parameters required to call API. |
This function generates mint transactions as messages. Once the gas fee for generating a message is calculated, the transaction is created by the function that executes messages.
* For a more detailed guide on calculating the gas fee and executing messages, please refer to functions 2 and 3.
Name | Type | Example |
---|---|---|
data | MsgMint | { owner: address, tokenURI: "https://firmachain.org/nft/metadata/bcf5cdajs-ff12...-d2han89nnha1" } |

}
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.
Name | Type | Example |
---|---|---|
wallet | Object (FirmaWalletService) | |
msgList | Array(NftTxClient.msgMint) | [ data1, data2, data3 ] |
334715
