Ability to mint asset and add inline datum

[bigirishlion]

I'm currently trying to craft a transaction that mints a token and provide datum for the UTxO output. I'm aware of the add_mint_asset_and_output but I can't figure out a way to do this and provide an output with datum.

Here's what I've tried:

let txOutputBuilder = serializationLib.TransactionOutputBuilder.new()
      .with_address(returnAddress)
      .with_plutus_data(plutusData)
      .next()
      .with_asset_and_min_required_coin_by_utxo_cost(
        multiAsset,
        serializationLib.DataCost.new_coins_per_byte(
          serializationLib.BigNum.from_str(dataCost)
        )
      )
      .build();
    txBuilder.add_output(txOutputBuilder);

    txBuilder.set_mint_builder(mintBuilder);

Any help is appreciated.

Hi @bigirishlion ! with_plutus_data(plutusData) adds datum to a tx output. But if you need to use a datum for a plutus mint script, you need to use MintBuilder API. Because for using a Plutus mint script, you need to provide a redeemer (not datum ) and a Plutus script to MintBuilder, they will be placed to a witnesses set by MintBuilder.

But if you need to create a tx output with inlined datum with_plutus_data would be enough.

Hey @lisicky. Thanks for the reply! Sorry for the confusion, I'm not asking how to send datum to a mint contract, I'm asking how to have an output with both a minted asset and inline datum.

@bigirishlion you can create MintBuilder and TransactionOutput ( for example by TransactionOutputBuilder) with the same assets amount and add them to the tx builder. But add_mint_asset_and_output should work too, but it less flexible.

Thanks @lisicky I was able to get it working using the code above and the MintBuilder.
