Carla Kirk-Cohen	c7ef4297c0	multi: update sweeping to allow different sighashes and claim scripts ... Taproot spends require a different sighash, so we update our HtlcScript interface to provide the appropriate sighash when sweeping. We also add distinct Timeout/Success Script functions to allow for tapleaf spends which have different locking scripts for different paths. Note that the timeout and success paths will be the same for segwit v0 htlcs, because it has a single branched script containing all spend paths. In future iterations, this differentiation of claim scripts can also be used to use musig2 to collaboratively keyspend P2TR htlcs with the server. This script can be expressed as PriorityScript (because we'll try to keyspend as a priority, and then fall back to a tap leaf spend). As we've done here, segwit v0 spends would just return their single script for PriorityScript, and the claim would be no different from our other claims.	2 years ago
Oliver Gugger	d5952f1202	multi: bump all dependency to use lnd 0.15.0-beta.rc4 ... This commit bumps all dependencies to be in line with what's required for the current release candidate of lnd 0.15.0-beta.	2 years ago
sputn1ck	efb6f75d60	swap: add lasthop, outgoingchanids to swapinfo	2 years ago
Harsha Goli	dec6dd7e70	swap: HTLCV3 added ... In this commit we add the version 3 htlc, which is implemented with taproot script spending the two payment paths: the claim path case, and the timeout case.	2 years ago
Harsha Goli	7a16e3b25d	multi: bump btcec/v2 and btcutil to new versions	2 years ago
Harsha Goli	f1a7d8fb49	multi: pass private, routehints from loopcli - loopd - loop server ... This commit passes routehints all the way from when/if the user passes them from the cli all the way to the backend loop server. If private is used, this commit passes that boolean down to different stages, where it is then converted into routehints. main: add --private and --route_hints to quote Adds --private and --route_hints flags to quote cli	2 years ago
Andras Banki-Horvath	0e7ed91d5d	loop: integrate the probe api with loop-in quote ... In this commit we add a call to the new probe endpoint directly into the loop-in quote call. Furthermore we add an option to include private channels in the loopin swap payment request. This is also useful for when users quote/probe directly using the client API and specify hop hints.	3 years ago
Andras Banki-Horvath	f786aaa016	loop: add support for the probe API	3 years ago
carla	d1c26a20da	multi: surface server swap initiation grpc error codes ... Formatting our error was stifling any grpc error returned by the server. Instead, we bubble up our grpc error, setting an unknown code if the server did not specifically return an error code.	3 years ago
carla	0e72c2bf92	loopin: handle EOF case for SubscribeSingleInvoice ... From lnd 0.13.0, the SubscribeSingleInvoice rpc will return an EOF once it has served a final state to the stream. This is handled in our lndclient wrapper by closing the channels that we send updates/ errors on. When we are exclusively consuming updates from these streams, we don't need to handle this case because we will receive our final update and exit. However, in the case where we continue to listen on the update channels after consuming the final update, we need to handle this EOF/closed channels case. This is done by setting the channels to nil after they're closed so that we no longer select on them but can continue waiting for our other cases to complete. We have similar handling in loopout's waitForHtlcSpendConfirmed.	3 years ago
carla	4911130671	loopin: store loop in on-chain fees	3 years ago
Oliver Gugger	2a732a4385	loop: add initiator string to user agent	4 years ago
Oliver Gugger	38ddbfb45d	mod+loopin+loopout: update lndclient, add labels to TXs ... We update to the latest lndclient that now requires a label when publishing an on-chain transaction. Instead of just adding an empty string, we use the proper labels added in a previous commit.	4 years ago
carla	7b56804bbe	multi: move label validation to rpc and simplify validation function ... Previously labels with reserved prefixes were added to provide us with a way to identify automatically dispatched loops. This commit moves the validation of these labels to the rpc level so that it will only apply to user-initiated swaps.	4 years ago
Joost Jager	c8666caf20	loopin: mpp pre-swap probe	4 years ago
Andras Banki-Horvath	133f3cac5f	multi: integrate the new htlc v2 scripts to loop in/out ... This commit bumps the current protocol version and integrates htlc v2 with loop in/out for new swaps, while keeping htlc v1 for any pending swaps with previous protocol versions.	4 years ago
Andras Banki-Horvath	71a7dec649	sweeper: set sequence to be able to sweep htlc v2 utxo	4 years ago
Andras Banki-Horvath	cd0a5f9f06	swap: extend swap to be able to create the V2 htlc	4 years ago
carla	9678c7817d	multi: add swap label to SwapContract and store under separate key ... This commits adds an optional label to our swaps, and writes it to disk under a separate key in our swap bucket. This approach is chosen rather than an on-the-fly addition to our existing swap contract field so that we do not need to deal with EOF checking in the future. To allow creation of unique internal labels, we add a reserved prefix which can be used by the daemon to set labels that are distinct from client set ones.	4 years ago

Joost Jager	a3b7fa5977	loopin: fail swap when htlc amount is incorrect ... Previously the swap would get stuck in a state where it wouldn't ever progress because the server rejected the htlc.	4 years ago

Andras Banki-Horvath	0aa978bd09	loopin: modify internally published htlc to use p2wsh	4 years ago
Andras Banki-Horvath	f0aff9b7bd	looprpc+loopin: support for native segwit htlcs ... This commit extends SwapResponse and SwapStatus with np2wsh and p2wsh htlc output addresses to support both nested and native segwit htlcs in loop-in. Furthermore the commit adds support for native segwith loop-in htlcs. When the htlc is paid internally, as of this commit we'll use NP2WSH, otherwise users are free to select whether to pay the NP2WSH or the P2WSH htlc.	4 years ago
Andras Banki-Horvath	87cc5571ef	general: add ExternalHtlc to SwapInfo and add comments	4 years ago
Andras Banki-Horvath	b2b0bad951	loopin+loopout: move htlc out of swapKit ... This commit moves htlc out of swapkit in preparation of adding separate p2wsh and np2wsh htlcs to loop-in swaps.	4 years ago
Joost Jager	b69e8cb275	multi: allow loop in last hop restriction	4 years ago
Joost Jager	535e964ec9	loopdb: migrate loop in channel to last hop ... A database field was already in place to allow channel selection for loop in. Unfortunately this field, which contains a short channel id, isn't easily usable for controlling the loop server payment. Because of non-strict forwarding, it is only possible to constrain a route to a specific last hop pubkey. This commit converts the existing field into a pubkey field.	4 years ago

Johan T. Halseth	0023d1a0da	looprpc: update to new server protos ... We update to new set of server protos where new Terms calls are added. Here static information will be returned from the server. We no longer have a feebase+feerate, but get a final fee directly returned by the server.	5 years ago
