Alice can choose to cooperate but is not obligated to do so. This change is backwards compatible. To attempt recovery, resume a swap in the "Bitcoin punished" state. Success depends on Alice being active and still having a record of the swap. Note that Alice's cooperation is voluntary and recovery is not guaranteed - CLI: `--change-address` can now be omitted. In that case, any change is refunded to the internal bitcoin wallet. diff --git a/swap/src/bin/asb.rs b/swap/src/bin/asb.rs index 3216adeeb..84fefc661 100644 --- a/swap/src/bin/asb.rs +++ b/swap/src/bin/asb.rs @@ -31,7 +31,7 @@ use swap::asb::config::{ use swap::asb::{cancel, punish, redeem, refund, safely_abort, EventLoop, Finality, KrakenRate};
