This guide is for merchants using the Cryptbrew iOS app and related services.

In short: Cryptbrew is a managed Lightning hub.
Customers pay a Cryptbrew invoice. We receive the payment on our infrastructure,
take a small platform fee, and automatically forward the rest to the payout wallet you register.
We do not store your wallet private keys or seed phrase.
1. How payments work
Register a payout destination in the app (Wallet): Lightning address (recommended) and optionally a Bitcoin on-chain address.
Create an invoice for a fixed amount of sats (or USD converted to sats).
Customer pays via QR (Lightning) or checkout. Funds land on Cryptbrew’s infrastructure.
We forward merchant net to your registered wallet after settlement (Lightning first when available).
You do not run a node or manage channels — Cryptbrew operates that infrastructure.
2. Payouts
Lightning address
Format you@walletprovider.com. Use Verify address in the app before saving when available.
On-chain fallback
Optional bc1… address when Lightning delivery is not available. Higher minimums and network fees apply.
Changing on-chain may require email confirmation.
What you receive
The amount you enter to charge is the merchant receive target.
The customer pays that amount plus the platform fee (gross-up).
Invoice stays locked until a payout destination is saved under Wallet.
3. Fees
Platform fee (Lightning): 1%, minimum 10 sats per invoice.
Gross-up: You enter what you want to receive; customer pays receive + fee.
On-chain / altcoin swaps: Network or Trocador costs are separate from the 1% platform fee.
4. Using the app
Invoice — keypad amount, optional cart/catalog, Charge → QR for customer.
History — payments and payout status.
Analytics — summaries and CSV export.
Wallet — payout destination, profile, retry if a forward needs another attempt.
About — help links, privacy, terms, sign out.
5. Status & amount due
“Paid” means the customer paid Cryptbrew. Forwarding to you usually happens automatically.
Amount due means sats are still waiting on the hub for a successful forward —
fix your payout wallet, then Retry from Wallet when shown.
6. Altcoins
Where enabled, Trocador on checkout may let customers pay with other coins.
Swap fees/timing are Trocador’s; Cryptbrew’s platform fee still applies on the settlement path as configured.
7. Security
Managed hub settlement — not a non-custodial peer-to-peer wallet app.
No storage of your personal wallet keys — only addresses you register for payouts.
