Hi, I'm looking to make some Monero, is there user testing I could do in return for XMR?

we don't have such a system currently

selsta: fair enough, thanks anyway. :)

Can you generate a transfer proof for an unconfirmed transaction? (is it accepted as valid by the wallet RPC?)

Try it. If it does not work, it should be easy to fix.

(note that it might be invalidated easily though)

Maybe add a "unconfirmed" flag to the RPC response too.

Where do fees come from? If I'm sending with transfer in the wallet RPC, do the fees come from that input or from elsewhere in the wallet?

They come from the inputs. The outputs sum up to slightly lower than the inputs.

If you ask the wallet to send X, the balance will decrease by slightly more than X.

People have asked for the ability to send slightly less than X instead, feel free to add that ability.

(optionally, of course, defaulting to the current behaviour)

<moneromooo> "If you ask the wallet to send X,..." <- So if I receive 0.1 XMR in one input, and I attempt to send all of it with the wallet RPC, then it would not be able to broadcast that output because the fees must be contained in the input?

If that's the case, is there a good way to estimate the fees at a given time for automating sending like that?

Yes, and there's a daemon RPC to get the base fee, and a simple is is about 1.2 kB IIRC, so multiply base fee by 1200 to get rough fee.

a simple *tx*

Or use sweep_all/sweep_single, which takes the fee of the input you're sending.

<moneromooo> "Yes, and there's a daemon RPC to..." <- Thanks so much for the help. I was having trouble finding that online.
