FAQ
Questions, answered.
No. Opening the app creates a free wallet automatically, stored on your device. There's no email, password, or account to set up before you can start using services.
Every service shows its price in sats before you run it. Fixed prices, not a subscription. Quick tasks cost a few sats; heavier work like image or document generation runs a few hundred.
Top up your wallet with Lightning sats or M-Pesa from the Wallet tab. Once you have balance, tasks are deducted automatically. If your balance runs low mid-task, you'll get a Lightning invoice or M-Pesa prompt to top up.
You're only charged for tasks that complete successfully. If something fails on our end after you've paid, the sats are automatically refunded as wallet credit.
Wallet balances and task history are encrypted at rest. Your wallet ID lives only on your device. We never ask for your name, email or phone number to use the core service.
Your wallet ID lives only on that device/browser, so clearing data or switching devices starts a fresh, empty wallet. Keep this in mind before topping up large amounts.
Yes. M-Pesa top-up converts KES directly to sats in your Ark Node wallet. No separate Lightning wallet needed to get started.
Your first question is free.
No signup. No card. Open the app, ask anything, and see how far a few sats go.
