Elle Mouton f8a36010e2 rules: add on-chain budget ... This adds an on-chain budget that handles requests and responses for the following endpoints: * OpenChannelSync * BatchOpenChannel The budget rule checks that the onchain fee rate is not violated and that pending and confirmed amounts are handled correctly. An edge case can occur when lit crashes or shuts down after the budget rule has forwarded a request but didn't receive a response yet. The pending budget is not removed in case the request didn't go through and is not accounted towards the spent budget in case the request did go through. To be able to handle these cases in the future we add a unique identifier to the request, that can be checked by calling LND's channel bookkeeping APIs. Not all of them expose the identifier yet, which is why pending actions cannot be deleted yet. This leads to underspending of the budget and can be fixed by user intervention by creating a new session. The memo prefix is removed when reading forwarding the bookkeeping requests for privacy reasons.		2024-07-02 18:21:41 +02:00
