You are sideloading a wallet that will hold real money. Do not take anyone's word for what is in the file, including ours.

The file

The signing key

The same key on every build, so this one never changes. Android refuses an update signed by any other.

Installing

Tap the download buttonAny browser on the phone.
Open the file, allow your browser onceAndroid warns about sideloading in general, not this file.
Open NIMmesh, allow BluetoothHow the phone finds other phones and relays for them.

This is real mainnet money. There is no test mode. Put in an amount you would not mind losing.

Permissions

Ten permissions, all needed. Anything not on this list is wrong: email [email protected].

Permission	What it is for
`BLUETOOTH_SCAN`	Find other phones running NIMmesh. Flagged `neverForLocation`, which is how the app avoids asking for your location at all.
`BLUETOOTH_ADVERTISE`	Let other phones find you, so you can relay for them.
`BLUETOOTH_CONNECT`	Open the link that carries the payment bytes.
`FOREGROUND_SERVICE` `..._CONNECTED_DEVICE`	Keep the radio alive while the screen is off. Android kills background Bluetooth otherwise, and a sleeping phone stops relaying.
`POST_NOTIFICATIONS`	The notification Android requires a foreground service to show. It is how you can tell the mesh is still running.
`INTERNET` `ACCESS_NETWORK_STATE`	Read your balance and broadcast, when you have a connection. The offline path never touches these.
`CAMERA`	Scan a payment QR code. Nothing is uploaded.
`USE_BIOMETRIC`	Unlock the wallet with a fingerprint instead of typing.

No location, no contacts, no storage, no analytics. Below Android 12 a Bluetooth scan needs location, so the app refuses to run there.

What works

Wallet on mainnetMesh unproven on Android

The wallet creates, restores, shows a real balance and sends, with the same keys as the iPhone build. Two Android phones have never passed a payment between them. The test guide has the run.

Why iPhone is limited

The iOS build is Ad Hoc: registered devices only, capped at 100. TestFlight rejected the first submission, and Apple's rule on crypto wallets from individual developers is the wall.
