  • signer : <SuiAddress> - the transaction signer's Sui address
  • package_object_id : <ObjectID> - the Move package ID, e.g. `0x2`
  • module : <string> - the Move module name, e.g. `devnet_nft`
  • function : <string> - the move function name, e.g. `mint`
  • type_arguments : <[TypeTag]> - the type arguments of the Move function
  • arguments : <[SuiJsonValue]> - the arguments to be passed into the Move function, in <a href="">SuiJson</a> format
  • gas : <ObjectID> - gas object to be used in this transaction, node will pick one from the signer's possession if not provided
  • gas_budget : <uint64> - the gas budget, the transaction will fail if the gas cost exceed the budget
  • execution_mode : <SuiTransactionBuilderMode> - Whether this is a Normal transaction or a Dev Inspect Transaction. Default to be `SuiTransactionBuilderMode::Commit` when it's None.


  • TransactionBytes : <TransactionBytes>
    • gas : <[ObjectRef]> - the gas object to be used
    • inputObjects : <[InputObjectKind]> - objects to be used in this transaction
    • txBytes : <[Base64]> - BCS serialized transaction data bytes without its type tag, as base-64 encoded string.
