What is DropBit?
DropBit is a mobile Bitcoin wallet and is the simplest way to send Bitcoin. You can download the wallet in the
iOS and Google Play stores, or by clicking here
What can DropBit do?
- 1. Recover your wallet by importing 12 recovery words
- 2. Show details of all of your ingoing/outgoing transactions
- 3. Use your device's camera to scan addresses in QR code
- 4. Send Bitcoin to phone contacts, Twitter or DropBit.me users, even if they don’t yet have a Bitcoin wallet
Do you provide any public source?
Yes, DropBit is open source. https://github.com/coinninjadev
Is DropBit an HD wallet?
Yes, DropBit is an HD (or "hierarchical deterministic") wallet. That means a new, unique address will be generated
every time you send or receive funds, which makes your transactions harder to track, keeping your financial business
yours. There’s no need to back up each address separately, each of them can always be restored using your wallet’s
12 recovery words. All addresses generated from the same wallet can be used to receive funds, and all funds
sent to any of these addresses will show up in your balance. The balance you see on your main wallet screens represent
the total sum between those addresses.
Issues with viewing the app?
If you are having issues viewing content within the app (text being cut-off, running off the screen or issues with the appearance of buttons), first go to the App Store or Play Store and make sure you’re using the latest version of DropBit. These types of issues may occur if you have changed any screen/text/font settings in your device’s ACCESSIBILITY. Common causes are using larger than normal text size or enabling a zoom (increasing the size of what appears in your screen). These features may need to be turned off or altered to view your DropBit app as it was intended.
How to send/receive Bitcoin in DropBit?
Via Address or QR Code
In order to receive coins from any other address you should provide your public address to the sender. To do so, you need to tap the “receive” button.
There you will see a QR code, which you can show to the sender if they have a QR scanner. Otherwise, you can
copy the address by tapping on it. You may also tap “share” to send your public address via other applications
such as Mail, WhatsApp, Signal, etc.
You can also can specify the exact amount that you want to receive by clicking “Add Amount”, but this works only with a QR scanner.
DropBit also allows people to receive Bitcoin via SMS, which is unique to our app. Here are the steps:
- 1. If someone with the DropBit app sends Bitcoin to a contact (mobile phone number), the recipient will receive a notification.
- 2. If the recipient does not yet have the DropBit app, the recipient will be notified that they have just been sent Bitcoin via SMS. They will then have 48 hours to install the DropBit app and set up their wallet to retrieve their Bitcoin.
- 3. If the recipient already has the DropBit app, they will receive an in-app notification that they have received Bitcoin.
- 4. Upon successful setup of a wallet, the sender will be notified and will be given a prompt to complete the send.
- 5. If the recipient does not install a wallet within 48 hours of receiving the notification the funds are never transmitted and remain safely in your DropBit wallet.
Why should I verify the phone number tied to my wallet?
If you don’t verify your phone number, you can not receive Bitcoin via SMS. However, you can send and receive Bitcoin via addresses, as you normally would, without verifying your phone number.
How do I verify the phone number tied to my wallet?
In the side menu, located in the upper left corner of the app, there is a "Phone" icon. Tap here to verify the phone number associated with your wallet.
Can I verify / check the status of my transactions?
- Yes, you can. You can either tap the side menu and select the "History" icon, or simply tap your balance in the upper-right
corner of the screen. Both actions will take you to your transaction history screen.
- Tap on any individual transaction to see more details about that specific transaction.
- Tap the Bitcoin address link (in light blue) to be taken from our DropBit app to
Coin Ninja block explorer. This will allow you to see details about that specific transaction block.
How many confirmations does DropBit require before a transaction is spendable?
- A transaction has one (1) confirmation when it is included in a block (mined). Each subsequent block is additional confirmation.
- DropBit allows you to spend funds once they are included in a block (one confirmation).
- A transaction with three (3) confirmations is considered “Confirmed”
- Once a transaction is confirmed, it will show Confirmed. This lets you know that the Bitcoin has been transferred successfully.
Sending Via Twitter
Another great option available for DropBit users is the ability to send transactions and app invites via Twitter. Here’s how it works:
- 1) After tapping the SEND button, a DropBit user has the option to send Bitcoin to a Twitter user by tapping the TWITTER button.
- 2) Next, the sender can select from Twitter users already in their contact list, or they may manually type a Twitter handle into the SEARCH bar.
- 3) If the selected Twitter user already has the DropBit app, and has verified their Twitter handle within the DropBit app, the transaction will broadcast as any other Bitcoin transaction.
a. If the receiver does not yet have the DropBit app, or their Twitter account verified within the app, that user will receive a Tweet with a link to download the DropBit app.
i. After downloading, if the receiver will be setting up a NEW WALLET, they should select CLAIM BITCOIN FROM INVITE, then follow the instructions below.
1. Set your PIN, then tap the I GOT A TWEET button.
2. If already logged into Twitter on your device, tap the AUTHORIZE APP button.
If not, then enter your Twitter login credentials and then tap AUTHORIZE APP.
3. The transaction will now broadcast to your DropBit wallet.
ii. If the user would like to restore an already established Bitcoin wallet, they may select RESTORE WALLET.
1. Next, enter the 12 recovery words for the wallet you’d like to restore.
2. Now you’ll be prompted to VERIFY your DropBit app; tap the VERIFY TWITTER ACCOUNT button.
3. If already logged into Twitter on your device, tap the AUTHORIZE APP button.
If not, then enter your Twitter login credentials and then tap AUTHORIZE APP.
4. The transaction will now broadcast to your DropBit wallet.
Why should I verify the phone number or Twitter account tied to my wallet?
If you choose not to verify your DropBit wallet via your phone number or Twitter account, you will not be able to send Bitcoin via SMS or by using Twitter handles. You will however still be able to send via QR scan or by copy/paste of an address.
How do I change the phone number or Twitter account tied to my wallet?
You can de-verify or change a phone number or Twitter account tied to your account by going to Menu > Verify > CHANGE/REMOVE (on either your phone number or Twitter account), that’s it.
Is my phone number kept private?
Yes. We are always aspiring to be as "zero-knowledge" as possible with regard to our users and their contact information. As such we only store the hash of phone numbers. Our hashing scheme is designed to balance privacy and ease of use. DropBit's service design does not depend on knowledge of a user's contact social graph.
We do our best to optimize the balance between making the app user friendly for onbaording new people to crypto, and the need for privacy.
I lost access to my wallet, and did not write down my Recovery Words. Can I get my wallet back?
If you did not import your DropBit wallet on any other device and you did not save a copy of your recovery words,
you have lost access to your wallet.
This is why it is critical to write down and store safely your recovery words.
I forgot my PIN, what can I do?
(Android) If you know your recovery words, you can delete DropBit application and download it again. Then, in newly downloaded
app you import your key words and create new PIN code. If you haven’t written down your 12-recovery words, unfortunately,
you will lose access to your funds.
(IOS) Because your wallet info (PIN/Recovery Words) are stored in your device’s keychain, you will need to restore your device completely to recover a wallet, if you’ve forgotten your PIN. MAKE SURE YOU BACKUP YOUR DEVICE
Settings > General > Reset > Erase All Content and Settings
i.Once you restore your device, when you open DropBit again, you’ll be able to RESTORE your wallet by reentering your Recovery Words, and then able to set your PIN.
How can I view my private keys?
Right now, we do not show private keys in the application. But you can always use your recovery words to recover
What do you do with the contacts on my phone?
We do not store any of your contacts on our server. Instead, during the phone number verification process, DropBit
sends us a cryptographic hash of your phone number. This hash is used for contact discovery. When a DropBit
user attempts to send via phone number, that number is also hashed and our server will inform the app if the recipient
is a DropBit user. Thus, your contacts remain safely on your phone and our servers never see contact details
unless an invitation via SMS is required.
Why doesn’t DropBit require any registration?
There is no need for any personal information such as names, emails, and phone numbers due to the fact that we do
not keep any users’ information, including their private keys. The only thing you must know are your 12 recovery words. These words are securely generated on your device and are never sent to our servers. The recovery words allows
you to restore your wallet on any other device at any time. Even if DropBit, as a company, doesn’t exist you
will be able to restore your wallet in any other wallet based on the same technology.
Will my money show up if I restore recovery words from another wallet?
In most instances, yes. DropBit will allow you to restore from another HD wallet that uses 12 seed words, and follows the BIP49 derivative path. However, some other wallets may be non-HD wallets, or follow another derivative path such as BIP32, BIP44, or BIP84. Your balance in DropBit will only reflect funds sent to addresses in the BIP49 derivative path, following the address gap limit defined in BIP44.
Wallets which do not support BIP 49
-Trezor Legacy BTC accounts( BIP44)
Does DropBit wallet support Sewgit?
Yes. We can send to any address type supported by libbitcoin. However our wallet will only generate Segwit receive
Does DropBit wallet support Bech32?
Bech32 coming soon :)
Does DropBit wallet support Lightning Network transactions?
Not yet, but we are working toward supporting this very soon.
Do you have resources that I can use to send bitcoin newbies to learn more about Bitcoin?
Which fee should I choose for my Bitcoin transaction?
We determine our fee options based on algorithm which calculates from the average transaction fees from the previously mined block. A new blocked is mined about every 10 minutes. While this is an accurate way to determine fees, unexpectedly high traffic (a backed up mempool) can cause slow-downs in transaction confirmations. Below are typical expectations when choosing a fee:
Fast: Highest tier priority. (1-2 blocks: ~10-20 min.)
Slow: Medium tier priority. (2-6 blocks: ~20-60 min.)
Cheapest: Lowest tier priority. (approximately 24 hours)
What is Dust, and why is dust protection beneficial?
“Bitcoin Dust” refers to very small amount of Bitcoin on an address with less value than the actual mining cost to send and confirm the transaction. Dust amounts (less than 1,000 Satoshis) can occur naturally, and they can also be intentionally sent to a wallet, essentially acting as a tracking device on that wallet. Because this amount is so small, it will need to be spent along with another output, meaning it can link your wallet to transactions you’ve sent containing said ‘dust’.
When DropBit’s “Dust Protection” is enabled (found in your Settings), any address in your wallet containing ‘dust’ will not be used, or sent (less than 1,000 Satoshis). This feature will also leave that amount in your wallet when using the “Send Max” feature, and often will result in a larger amount of Bitcoin being sent from your wallet.
What are DropBit's transaction fees?
Transaction fees are inherent to the Bitcoin blockchain network. DropBit does not charge any fees to send or receive Bitcoin. Transaction fees are paid to miners who confirm Bitcoin transactions on the blockchain. The higher the fee you’re willing to add to your transaction, the higher your priority will be when confirming the next block (group of Bitcoin transactions waiting to be confirmed). When sending a transaction through DropBit, we offer you different speed/priority options when sending your Bitcoin transactions: Fast, Slow, and Cheapest
