extractlv
extractlv is a small set of Python tools for pulling TLV records out of a Lightning node and doing something useful with them.
Why it matters
Podcasting 2.0 payments carry their meaning in TLV records rather than in the payment amount, so any tool that wants to know who boosted, on which episode, with what message has to read those records first. This was one of the early demonstrations that the data was there and could be extracted.
How it works
It talks to an LND node over gRPC and reads the custom TLV records attached to Keysend payments, exposing the Boostagram payload underneath.
