Bitcoin or digital dollars, your call.
Part of your balance can sit in digital dollars, without leaving the app.
One balance. Many networks.
Spark, Lightning and on-chain Bitcoin meet in the same wallet. From it you can also send USDT and USDC to Tron, Ethereum, Solana and other chains, or receive them from there as bitcoin or digital dollars. Every send shows its network, fee and total before it goes.
USDT and USDC, in and out.
Get paid in USDT or USDC from another network, and pay an address on one, right from your wallet.

TempoReceive
Pick the coin and its network, type the amount and share the address. Once the provider pays it, it reaches your wallet as bitcoin, or as USDB, a digital dollar on Spark, when the dollar wallet is on.
Send
Paste a USDT or USDC address, pick its network and see about how much arrives before it goes. It is paid in bitcoin from your balance.
Who carries them
USDT and USDC never sit in your wallet as a balance. Orchestra, run by Flashnet, carries them from one network to another. On a receive, Orchestra holds the coins from the moment they reach its address until it pays yours. Voltz takes part in no step and adds no fee.
yourname
Your address to receive. Easy to say, easy to remember.
And there is more.
you
Your address, on your own domain
Your Lightning address can live on a domain you already own, set up with one DNS record. The domain stays yours, and if the address on it ever pauses, your wallet keeps working.
The people you work with can have their own address on it too.
Several wallets, one app
Keep more than one wallet on the same phone, each with its own recovery words and Lightning address, and switch between them whenever you want.
Buying bitcoin, from the wallet
You can buy bitcoin from inside the wallet. It goes straight to your wallet's own address, and Voltz never touches the money.
Your keys stay yours.
Voltz never holds your money, and nothing moves it without your keys.
Keys made on your phone
Your keys are created on your phone and never sent to Voltz or to any server. The only copy outside it is the recovery words you write down. A six-digit PIN, with Face ID or fingerprint if you want, guards the app.
Dice, if you prefer
Roll a real die to make your recovery words, with no randomness from the phone.
A secret on top
An optional passphrase adds a secret of your own to your recovery words.
The address service can't freeze it
The service behind your Lightning address never receives your keys, so it cannot spend, freeze or seize your balance. See what it can see.
Speaks your language.
The app follows your phone's language and currency, and you can change both.

Create your wallet
Your wallet starts on your phone, from 12 or 24 recovery words that only you see, or from the words of a wallet you already have.
Write down your words
The app checks your written words, in order, before your wallet opens.
Send and receive
Your Lightning address is ready from the first day, and every send shows its network, fee and total before it goes.
F.A.Q.
- Does Voltz hold my money?
No. Your keys are created on your phone and never sent to us, and no payment leaves without their signature.
- What if I lose my phone?
With your recovery words you open the same wallet on another phone.
- Which networks does Voltz use?
Spark, Lightning and on-chain Bitcoin, through the Breez SDK Spark inside the app. With an amount, one Bitcoin QR code can be paid over Lightning or on-chain. USDT and USDC go out to and come in from Tron, Ethereum, Solana and other chains through Orchestra, run by Flashnet, landing in your wallet as bitcoin or digital dollars.
- What can the Lightning address service see?
It never receives your keys, and it cannot spend, freeze or seize your balance. It does see which wallet holds which address, the payments made through that address, the comment a payer attaches and the device registered for notifications. If it were compromised, it could hand a payer someone else's invoice, stop serving an address, or send or hold back its notifications.
- Can I hold digital dollars?
Yes, as USDB, a digital dollar on the Spark network, next to your bitcoin. It is issued by a third party, aims to be worth one US dollar, is not guaranteed by Voltz and can lose its peg. Converting between the two happens in a Flashnet pool, is signed on your phone, and Voltz is not a party to it.
- Does Voltz take a cut of my payments?
No. Voltz's revenue comes from its software, never from a spread on a payment or a conversion. The fees the app shows belong to the network or to the provider doing the work.
- When can I get Voltz?
It is not in the stores yet. Voltz is coming to the App Store and Google Play, for iOS and Android.
More answers are on the support page.
Coming soon.
