[Cardano] - Load CBOR created with eternl wallet on preprod

[studiowebux]

Hello,

I was wondering if it is possible to load a cbor from a wallet. (My end goal is to use Deno + CSL on the backend)

I tested this cbor encoded payload:

But was unable to load it using ADATransaction.fromCborBytes()

I have tested multiple things, but the recurrent issue are these two :

Your transaction encoded the inputs in the body using a set instead of a list. Some packages use a set to encode transaction inputs, but this is not standard for Cardano transactions, which typically use lists.

To fix this issue for your current transaction, you can change the template type from CborListValue to CborSetValue in this file

I will check further details to confirm if sets are supported by the Cardano standard. If they are, I will implement support for decoding them in a future update.

@studiowebux now cardano transaction can be deserialize inputs as Set
