How to create pset with issuance

[altafan]

Hello,

I'm trying to use the CLI to create a pset (v2 format) in order to issue a new asset. For simplicity, I'm going for a fully unblinded pset. These are my steps:

$ e1 sendtoaddress ${issuer_unconf_addr_1} 1
$ e1 generatetoaddress 1 $(e1 getnewaddress)

# fund the issuer and retrie ${issuer_utxp_txid} and ${issuer_utxo_vout}

$ e1 calculateasset ${issuer_utxo_txid} ${issuer_utxo_vout} 0000000000000000000000000000000000000000000000000000000000000000 false

# retrieve ${issued_asset} and ${issued_token}

$ e1 walletcreatefundedpsbt '[{"txid": "${issuer_utxo_txid}", "vout": ${issuer_utxo_vout}, "asset_entropy": "0000000000000000000000000000000000000000000000000000000000000000", "issuance_amount": 1000, "issuance_tokens": 1, "blind_reissuance": false}]' '[{"${issuer_unconf_addr_1}": 0.00001, "asset": "${issued_asset}"}, {"${issuer_unconf_addr_2}": 0.00000001, "asset": "${issued_token}"}]'

This always produces the error:

error code: -4
error message:
Insufficient funds

Can someone help me figuring out what's wrong with this?

Thanks for filing this.

What version of Elements are you using? I notice that you tagged this GUI but the issue is about CLI commands -- can you confirm this this only a problem with the CLI?

[altafan]

Yeah, sorry about that, i didn't notice the label was already there when I opened the issue.. this is relative to the CLI, not related to GUI.

I'm running version: Elements Core RPC client version elements-0.21.0.1

I managed to create the pset with the help of converttopsbt, so basically I created a raw transaction, added the issuance with rawissueasset and then converted the tx into a psbt with the mentioned command.

This is the starting raw transaction:

This is my finalized pset:

And this is the raw tx extracted with finalizepsbt:

If you decode them, you can see:

• the input of the starting raw tx has the issuance set
• the input of the pset has issuance amounts
• the input of the extraced raw tx is missing the issuance and, in fact, the tx does not get broadcasted with sendrawtransaction with the error error code: -26 error message: bad-txns-in-ne-out, value in != value out

I tried the PSBT commands (converttopsbt, walletprocesspsbt, finalizepsbt) and got the same result (problem). The problem seems to be with finalizepsbt.

https://github.com/ElementsProject/elements/blob/elements-0.21.0.1/src/psbt.cpp#L126-L132

• It would be better to match the following implementation of txout.
  • https://github.com/ElementsProject/elements/blob/elements-0.21.0.1/src/psbt.cpp#L140-L152
• It seems that txin.assetIssuance.nAmount and txin.assetIssuance.nInflationKeys should be judged separately. Because in the case of reissuance, only txin.assetIssuance.nAmount is used.
