Main features

You can send money to any friend by using either his/her HandCash $handle or Paymail address. Most of other Bitcoin SV wallet apps already offer Paymail, which in short is just your Bitcoin address. It looks just like an email address, but with the domain provider of a Bitcoin SV wallet service. For example, it could be ryan@moneybutton.com or alex@handcash.io.
Alternatively, you can send money to any valid Bitcoin SV legacy address. Just copy the receiving address, go to "Send Money" and a dialog will pop up asking if you want to use the copied address as receiver for a payment.

Your friends can send you money to your $handle or through your personall handcash.me page (i.e handcash.me/john). If they are not using HandCash, they can use your Paymail address. For example, if your handle is $alex, your Paymail address for HandCash would be alex@handcash.io - You can check yours at "+ > Receive" just to be sure! Alternatively you can get paid to a Bitcoin SV legacy address by scanning your QR code under "Display my BSV address".

We are working on an in-app top up service for our users. Meanwhile, you need to have an account on an exchange such as Bittrex, Bitvavo...
HandCash' "Pay" feature is only meant to work with valid Bitcoin SV payment requests - which is the safest and nicest way to pay both online and in retail stores. Its main attribute is that the amount to pay is predefined by the commerce. In most cases you won't have issues with this, however, if you are trying to send money to another Bitcoin wallet via QR code, it won't work unless it's a valid payment request. We disabled sending to "raw" Bitcoin legacy addresses via QR code for security reasons -although you can do it manually by copying a legacy address- as this format is valid accross chains and new Bitcoin users have repeatedly sent money into the void effectively by allowing this.
For efficiency reasons, we only notify peer-to-peer transactions, which at the time are only $handle to $handle payments. In the near future we will also display notifications for Paymail transactions as it will move from non-peer-to-peer to peer-to-peer in the coming weeks. Legacy Bitcoin transactions, because of their non-peer-to-peer nature, will be phased out in the coming weeks therefore don't expect them to be notified. You can check if you've got a new legacy payment in your account by entering the Payments menu.
Yes you can! Right when you are asked to type the amount to send to a friend, you'll see the "Add a note" button below the amount area. You can write up to 30 characters, including emojis!

Account management

Your HandCash Account is a combination of two different secret keys held by two independent companies for your convenience, this way you don't have to store them yourself. As long as you keep your credentials updated, you will be able to access your HandCash Account and funds.
Yes, you can. Right now you must contact support@handcash.io and request it, but in the near future you'll be able to do it right from your HandCash app in account settings.
You can have up to five $handles tied to your main HandCash Account. The way this works is that there is a master phone number and each sub-account needs a different email address - we do this to improve security.
That means you didn't migrate your account to our keyless system yet. Unfortunately our team cannot help you access the funds - but we might be able to help you recover your $handle for a new account.

About Security

HandCash is a non-custodial Bitcoin service, so we technically do not hold your money and are incapable of accessing it without your permission. Your funds are safe only as long as you keep your credentials updated.
HandCash is a very safe non-custodial Bitcoin SV wallet. However, it is aimed at small payments and only for storing small amounts. We advise not trusting HandCash with your life savings as we do not offer any insurance and we do not own a banking license of any kind.
HandCash is Keyless (does not require users to store a traditional Bitcoin seed or "twelve words") thanks to its proprietary system based on Threshold Signatures. This allows us to offer a non-custodial service while making it easier for every user to access their funds without having to safeguard a password. The full key never gets to exist, it's a system based on partial signatures by different trustholders.
No. This applies to all apps that use fingerprint or face authentication: this personal information is stored in your phone inside a secure chip that no other part of the phone can access to. That chip only responds "true" or "false" if the scanned face or fingerprint matches the with the one securely stored.
Your HandCash Account is composed of two different secret keys, each held by a different company. The way you access your account is by authenticating individually with each company to generate authentication tokens with each company. For every transaction, you are asking these "trustholders" individually to partially sign a payment in your regard. By granting permissions to third party apps to make payments in your regard, you are giving permission to both trustholders to partially sign more payments ordered inside these third party apps within your predefined "Spending limits". You can always revoke access to your funds to any app right from the HandCash app, inside the Connected Apps section.

About Bitcoin

Bitcoin SV (BSV) is a currency after all, that means its value it's also fluctuating against other currencies. Your real balance is the amount of "satoshi" you see in your home card, below the amount in your local currency. That's the amount of Bitcoin SV (BSV) you own. The local currency amount on top is just the equivalent of that amount in the local currency of your choice, so you better understand the amounts you are dealing with, at current exchange rates.
Duro is a universal currency for apps and games. A Duro is equal to 500 satoshi of BSV (or 0.000005 BSV). Duro mode makes this the default currency for HandCash and inside compatible apps. This way your balance remains stable independent of fiat currency (like USD, EUR...) fluctuations. This is a great way of pricind game items and app actions in a universal way, with our own money system. Give it a try and let us know your thoughts!
You only pay network fees in HandCash, which is what the network charges for handling your transaction. They are so small you won't notice, like 2 USD cents every 100 transactions you make. And they will get lower -and disappear in some cases- in the near future.
The most common usage for Bitcoin SV (BSV) is to use it for nanopayments inside apps and games. Some services allow you to make money by creating content, or charge you very tiny amounts of Bitcoin per action as business model instead of selling your content and private information to advertisers, or use these small payments to buy premium content as you go, instead of asking you for a long term subscription.
The magic of Bitcoin is that's a distributed system without an owner - it automatically rewards all participants who voluntarily maintain and secure the network. Think of it of some universal cash system that keeps itself alive thanks to economic incentives. The more people we have using it, the safer and cheaper it becomes.
No. Definitely. In fact, it's traceability and transparency is what makes it work within the law. This is something particularily true with the Bitcoin SV (BSV) network, which we use, as it's the most business and regulation friendly evolution of Bitcoin. Some might say it's the most faithful representation of the original principles of Bitcoin.
