How to use
Meldrino
Meldrino is designed to be simple. You don't need to be technical to use it — if you've already got crypto wallet apps on your phone, Meldrino just reads them for you.
Section 01
Installing Meldrino
Getting Meldrino onto your phone is exactly like installing any other Android app. Head to the Google Play Store, search for Meldrino, and tap Install. That's it.
The app is completely free and there's no account to create. You don't need to hand over an email address, pick a password, or go through any sign-up process. Just install it and open it.
Once it's open, Meldrino gets straight to work — you don't need to configure anything before it starts showing you your balances.
Right now Meldrino lives on Android. If you're an iPhone user, it's on the roadmap — Meldrino is being built to run on both platforms, and the iOS version will follow once the Android experience is exactly where it needs to be.
Section 02
How wallet detection works
The moment you open Meldrino, it takes a quiet look at the other apps installed on your phone. If it finds any crypto wallet apps it recognises, it adds them to your dashboard automatically.
You don't point it at anything or paste in any addresses. Meldrino finds your wallets the same way your phone's app drawer finds your icons — it just knows what's there.
Your keys are always yours. Meldrino never asks for your seed phrase, recovery words, or private keys. It can see that a wallet app is installed, but it has no access to the wallet itself — only the balance that the wallet makes publicly available.
Meldrino currently recognises these wallets:
If you install a new wallet after Meldrino is already running, just close and reopen the app — it will pick up the new wallet straight away. More wallets are being added with every update.
Section 03
Reading your balances
The main screen is your dashboard. Every wallet Meldrino has detected appears here with its current balance, so you can see everything at a glance without switching between apps.
Balances are fetched fresh each time you open the app. If you've just made a transaction and want to see the updated figure, pull down on the screen to refresh — the same gesture you'd use to refresh emails or a social feed.
Tapping on any wallet in the list takes you into more detail — recent transactions, the full balance, and anything else available for that particular wallet.
Some wallets show their balance immediately. Others — like ZBD Lightning — need a one-time connection before Meldrino can read them. If a wallet shows as connected but has no balance, see Section 4.
Section 04
Connecting ZBD Lightning
ZBD is a Bitcoin Lightning wallet — and unlike most of the wallets Meldrino detects, it's custodial, meaning ZBD holds your funds on your behalf. Because of this, reading your ZBD balance requires a one-off login step to prove to ZBD that Meldrino has your permission.
The good news is you only ever need to do this once. After that, Meldrino remembers the connection for around 30 days before it needs a quick renewal.
To connect, you'll need to be near a computer — a laptop or desktop will do — because the process uses a QR code that appears on your computer screen and gets scanned by your phone.
On your computer, open a browser and go to meldrino.duckdns.org/zbdconnect. A QR code will appear on screen. Now pick up your phone, open the ZBD app, and use its built-in scanner to scan that code. ZBD will ask you to confirm the connection — tap Approve.
Once you've approved it, a second QR code will appear on your computer screen. This one goes into Meldrino — open the app, navigate to the ZBD Connect screen, and scan it. Meldrino will store the connection securely on your device, and your Lightning balance will appear on your dashboard.
Nothing leaves your phone. The token Meldrino uses to read your ZBD balance is stored only on your device. It is never sent to any Meldrino server or third party.
If the connection ever stops working — for example after the 30-day expiry — just repeat the process above. It only takes a minute.
