And how is the amount of liquidity calculated?
reply
  • Inbound liq. = channel size - outbound liq - channel reserve - commit fee
  • Outbond liq. = channel size - inbound liq - channel reserve - commit fee
  • Channel size = UTXO amount locked in the channel opening tx
  • Commit fee = First-to-fill sats in LN channel that acts as a emergency funds to get your part of funds confirmed on-chain. Usually equal as the Onchain fee
  • Channel reserve = Mutually-agreed fidelity bond that deters channel counterparty from publishing fraudulent close. Usually 1% of channel size
