Pset building inconsistency

[Saleciani]

Currently, we are able to build a pset with and it will return an error if there are no funds in the wallet.

I do not understand if it is a lwk-dart bug or a a lwk inconsistency.

But:

We can set the fee to as low as possible and the pset will build, only when trying to publish we will get an error.

I think that the pset building should fail not just when the amount is very close to the maximum limit (so that there is no more amount for the fee) but also when the fee is too low for it to be published.

We should not be able o build a pset with a fee so low that won't be accepted by nodes.

What do you think?

Update:

Pset building also returns insufficient funds error when we have

EX: 6000 sats in the wallet

Total fee: 260 sats

Sending amount 5600 sats.

This means that there is outstanding unspendable balance in the wallet 🤔

yes, i reported this to lwk. we should get a patch soon.

we will also have drain soon.

i've noticed right now a buffer of around 800 sats is required

Is this buffer supposed to be a feature or a bug? Do you know? 😃
