This pure function creates signed commit transaction, using various inputs passed as struct TaprootSignedCommitTxInputs and a signer. This is needed to be able to store the inputs without a signature in SCB and sign the transaction in chantools scbforceclose. See https://github.com/lightningnetwork/lnd/pull/8183/files#r1423959791
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 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.
