How to burn

[gus4rs]

Guess this is more a usability question than a bug.

Trying to burn an inscription with

ord wallet burn  --fee-rate 20 --postage 1sat <inscription id> 

and am being greeted by

error: JSON-RPC error: RPC error response: RpcError { code: -25, message: "Unspendable output exceeds maximum configured by user (maxburnamount)", data: None }

This is a bitcoin core fart preventing sending funds to OP_RETURN. My understanding is this param (maxburnamount) should be passed to sendrawtransaction, so nothing I can do.

Is the burn feature useless then?

If I use the same burn command above but with dry-run then copy the psbt, import it in Sparrow and broadcast, it gets confirmed, and apparently it works

Damn. I think to make this work we would need to add support for maxburnamount here.

@raphjaph If you want I can have a look at this together with #3977 this week.

[raphjaph]

Ah damn, our mockcore tests strike again. @onchainguy-btc yes that would be great. Best to split these different issues into separate PRs for easier review.

[gus4rs]

Bro, you seriously didn't try to run the burn command even once for real? 😂

When it comes to Core, an outdated spaghetti full of convoluted flags, work arounds, obnoxious API, this is asking for trouble lol

I'm starting to become one

Managed to pass the max burn amount on my local ord setup. Now running into this error:

error: JSON-RPC error: RPC error response: RpcError { code: -26, message: "tx-size-small", data: None }

Seems to be related to this issue. Need to investigate further 🤔

[onchainguy-btc]

Works when I add some random bytes to the OP_RETURN output to increase the tx size. @raphjaph before submitting the burn tx, we could check the tx size and only if too small add some bytes. Or do you have a better idea?

This should now be fixed in #4106
