In this commit, we fix an existing within lnd. Before this commit, within NewBreachRetribution the order of the keys when generating the sender HTLC script was incorrect. As in this case, the remote party is the sender, their key should be first. However, the order was swapped, meaning that at breach time, our transaction would be rejected as it had the incorrect witness script. The fix is simple: swap the ordering of the keys. After this commit, the test extension added in the prior commit now passes.
lnwallet
The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
