Analysis

OVERVIEW

Swaps between Lightning, on-chain Bitcoin, and Liquid settle through hash time-locked contracts, so the operator never takes custody and there is no account or deposit window to freeze.

LIMITS

Scope is movement between Bitcoin layers, not cross-asset privacy: both legs leave footprints that amount and timing correlation can connect, and Lightning routing has its own metadata.

USEFUL FOR

Moving value between Bitcoin layers without an account or custody exposure.
