The offline pocket
A little ready.
For a little further.
Set aside a payment note while connected. Take it with you when your signal stays behind.
Less signal. More possibility.
A wallet for the in-between
Life moves. Even offline.
For connected days. And the moments in between. Exchange a payment nearby, keep the receipt, and settle when you’re back online.
Android · Current build uses test credit only.
Made for Nepal. A little less distance.
A little less signal. Still a connection.

Made for real moments
A small wallet.
A little more freedom.
The café around the corner. A friend down the road. Not every connection needs a network.
A little ready.
Nearby exchange
Closer is
all you need.
QR, Bluetooth, or Wi-Fi Direct. A signed exchange between compatible phones, without mobile data.
From here to there
Three small steps.
One less thing in the way.
01
Before you head out
Set a little aside.
While online, reserve an exact-amount note for your offline pocket. The current build supports notes up to Rs 500 in test credit, with a 24-hour expiry.
02
In the moment
Meet phone to phone.
Review the recipient and amount, then exchange nearby. Use QR, Bluetooth, or Wi-Fi Direct. Experimental NFC uses a two-tap flow on supported phones.
03
Back in range
Reconnect. Catch up.
Your offline receipt stays pending until sync. When you reconnect, the server settles the first valid redemption—once, not again on every retry.
Thoughtfully built
Good design.
Clear boundaries.
A calmer experience doesn’t mean hiding the important things. Here’s what Paila does—and where the current build draws the line.
Read the security model
Device-held signing keys.
Encrypted local storage.
Encrypted local storage.
Does Paila move real money?
Not in the current release. Paila uses test credit only—not real NPR, a bank balance, or redeemable funds. There is no cash-out, and the server refuses real-money mode.
The website preview is an illustration. It does not connect to a wallet, create a real transaction, or move any funds.
Is an offline receipt already settled?
No. An offline exchange and settlement are different steps. The signed exchange is stored locally. Settlement happens after reconnecting, when the server accepts the first valid redemption.
Offline double-spending is not fully solved: a compromised phone could sign the same note twice. Only the first valid redemption settles. Don’t treat a pending receipt as a guaranteed payment.
Which nearby methods can I use?
Paila supports QR exchange, Bluetooth, and Wi-Fi Direct on compatible Android devices. Hardware, operating system support, and permissions can affect availability.
NFC is experimental. It uses a two-tap exchange between supported HCE-capable phones, rather than promising universal tap-to-pay.
What protects the wallet—and can I recover it?
Signing keys use ECDSA P-256 in the Android Keystore, and local storage is encrypted with AES-GCM. Issuer keys stay on the server.
There is currently no account recovery. Uninstalling loses the test wallet. APK obfuscation is not an impenetrable security boundary, and this build must never be used with real funds.
Nothing behind the curtain.
Take the next small step
Less distance.
More possibility.
