Why is there a minimum balance required?

Transactions over Bitcoin's Lightning Network require a transaction fee paid by the sender of the payment.

Transaction fees are unknown before making a payment, thus we keep a fee reserve as a minimum balance for your account. That fee reserve equals 1% of the transaction amount or 10 sats - whichever amount is bigger.

If you want to learn more why we need to do that and learn about the attack that we're preventing with those measures, you can read about it here: https://github.com/Reckless-Satoshi/ln-fee-siphoning

If you face problems sending sats from your Alby Account, please try sending them in smaller amounts and remember about transaction limits.

If you want to close your Account and face issues withdrawing the last few sats, we're happy to help. Just shoot us an email at [e-mail] with details.
