how you've been building out your transaction? Have you tried using `TransactionBuilder`?

It seems like you haven't signed your transaction before you tried to send it to the network.

Here's a [link](https://github.com/Emurgo/cardano-serialization-lib/blob/master/doc/getting-started/generating-transactions.md) to the cardano-serialization-lib doc where they describe how to build transaction using `TransactionBuilder`.

Also, you can take a look in the spacebudz repo in the `initTx` method where the `TransactionBuilder` is used.
