[christianschmitz]

If you have some spare utxos, you could use them to cover those fees: tx.finalize(networkParams, changeAddress, spareUtxos)

[christianschmitz]

You need to dump the complete body to be able to debug this properly (i.e. all the inputs and all the outputs)

[aleeusgr]

@christianschmitz thank you for responding. I will experiment with utxos next, here is tx.dump().body:

total input: 10000000 total output: 10000000

And fees will be > 0. Including some spareUtxos will be the easiest way to cover the fees.

[aleeusgr]

I thought that the purpose of the collateral to cover fees. Fair enough I stand corrected.

:thinking: I network.createUtxo but it does not show up...

lockAda takes all utxos from a wallet and leaves it with only one, I think I should add an explanation to it.

Or should I fix it?

[aleeusgr]

• [ ] add spare utxo https://github.com/aleeusgr/potential-robot/blob/d799586672f3daf1ce59a769a35256435468c24b/tests/helios-vesting-cancel.test.ts#L135

My wallet does not have spare utxos: my lockAda tx had a list of utxos's as input, and the output of the lock transaction sends all the change to a single utxo in alice.address;

if I duplicate https://github.com/aleeusgr/potential-robot/blob/d799586672f3daf1ce59a769a35256435468c24b/tests/helios-vesting-cancel.test.ts#L43 even after a transaction, my test shows only one utxo in alice.address; maybe I can only add utxos to a wallet if it didn't have any transactions, only for emulator instantiation. :thinking: A good way to do is to have several utxos at emulator instantiation and have lockAda consume only one utxo.

[aleeusgr]

@christianschmitz thanks for your help, I solved it.

I changed tx building process so that it consumes only one utxo, while api requires a list. Adding all utxos seems to be bunching stuff up together in one utxo in the transaction output (I got change of its value if I added network.createUtxo, and if I did so after submitting a lockAda transaction, new utxos did not appear in the wallet address.)
