History
Calvin Zachman f5fb64e552 add new max channel size config option 
- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC

README.md

lnwallet

Build Status MIT licensed GoDoc

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.
