The merchant home screen for Bitcoin.
Ring up sales. Hide the keys. Keep every server in one app.
CryptoTxn is not a wallet.
It is the control panel for the tools you already run — without handing the company funds to whoever is on the till.
Instance online
A shop should not live in twelve Safari tabs.
BTCPay, the shop, POS, two wallets, mempool, the node. The till should not be a pile of bookmarks.
Too many links
BTCPay, POS, shop, wallets, mempool, node.
Wallet POS leaks power
A simple wallet at the register often means staff can open the money.
No single status
Is the instance online? Is the chain synced?
Employees take payments. They never see the money.
Logs and dashboards stay on the owner side. They do not sit on the till phone.
Simple wallet POS
- Device holds or opens a wallet
- Staff can reach balances
- One app trying to be cash register and vault
CryptoTxn
- No coins in the app
- Staff PIN opens the POS keypad only
- Owner keeps BTCPay admin, Blink, Blue Wallet, logs
You decide which tiles staff can tap. Default is POS only.
Lock the phone to the app with Guided Access. See Support.
Admin PIN and Face ID for admin and wallets.
Staff PIN opens the POS keypad.
Your instance. Your rules.
You choose the stack. Hosted instance or your own server. Your URLs.
Hosted by CryptoTxn
Free
Public instance at cryptotxn.net. Same grid: admin, POS, shop. Plugins are limited to those on your instance, plus the NFC Manager.
My own server
One-time €9.99
Paste your BTCPay URL. Optional local URL and onion URL. Status comes from /api/v1/health. Extra tiles for Umbrel, mempool, Public Pool, Cloudflare, anything you host.
Bolt cards from the owner’s phone.
Write, read, and format Bolt cards for the backend you already run — LNbits, or the Boltcard Factory on your BTCPay Server.
NFC Manager
Owner only
- Face ID first, then your 6-digit admin PIN. Never the device passcode.
- Card keys are stored in the iOS Keychain on that iPhone. They are not in the app’s saved data, backups, or usage log. CryptoTxn has no access to them.
- The app runs no server and no Lightning backend.
New phone?
Keys do not move automatically

FAQ
No. CryptoTxn never stores seeds, xpubs, or balances.
No. It holds no seed phrases, xpubs, wallets, or coins. If you use the NFC Manager, Bolt card keys are stored on the owner’s iPhone.
Only if you mark that tile as staff-visible. Out of the box they only get POS.
No. Payments stay on BTCPay (cryptotxn.net or self-hosted).
No. Hosted mode is the easy path. Own-server mode is for people who already run the stack.
