Frequently Asked Questions
What is BOLT12?
BOLT12 is a new Lightning payment standard that enables reusable payment offers. Unlike BOLT11 invoices that expire, a BOLT12 offer can receive unlimited payments forever.
Is it really self-custodial?
Yes. You hold your own keys. We never have access to your funds. Your 12-word recovery phrase is the only way to restore your wallet.
What happens if I lose my phone?
No problem. Just restore your wallet using your 12-word recovery phrase on any new device. Your funds are always safe on the Lightning Network.
How do I receive mining payouts?
Copy your BOLT12 offer from Bolt21 and paste it into your mining pool dashboard (like Ocean). Payouts will arrive automatically.
