PSA: If you ever had channels with LNBIG in the early days (2018-2021), read this! If you think you still have sats in such channels that you couldn't recover (e.g. your node broke down, no channel backup), there now might be a way. You only require your seed.

Try running chantools sweepremoteclosed on the latest version (v0.13.6): https://github.com/lightninglabs/chantools/releases/tag/v0.13.6

There are over 2.5k channels and over 10 BTC unspent! Big thanks to LNBIG for providing the data necessary and MrDonty for the idea/initiative.

Please RT for visibility!
