EXOS Cloud Wallet
Installation on Windows:
Three versions of EXOS-Electrum are available for Windows. The one labeled “Windows Installer” is the most convenient.
1- Window Installet (setup): install EXOS-Electrum, with its Windows Menu icon, and the uninstall option. The wallets and config files are under %appdata%\EXOS-Electrum (\Users\YourUserName\AppData\Roaming\EXOS-Electrum).
2- Portable: EXOS-Electrum will not be installed (not icons/links in the Menus), and it will run directly from the program itself. The wallets and config files are under the directory electrum_data located at the same level where you run the executable file.
3- Standalone: EXOS-Electrum will not be installed (not icons/links in the Menus), and run itself. The config files under %appdata%/EXOS-Electrum.
For the installations in this guide, we make reference to the version 3.3.4, however the installation process applies to any other version.
Installation on Mac
Download the macOSX Executable - EXOS-Electrum-3.3.4-macOSX.dmg
Double-clicking the downloaded file opens a mounted volume. Drag the EXOS-Electrum icon into your Applications folder. This appears to the left of the window under Applications. Open the Applications folder and double-click the EXOS-Electrum icon.
You may receive an error message stating that EXOS-Electrum “can’t be opened because it is from an unidentified developer.” Should this happen, locate EXOS-Electrum in your Applications folder then control-click on it. Select “Open” from the menu, then click the “Open” button on the popup.
Installation on Ubuntu Linux
Provide executable permits to the file just downloaded before you run it:
$ chmod a+x EXOS-Electrum-3.3.4-x86_64.AppImage
$ ./EXOS-Electrum-3.3.4-x86_64.AppImage &
Launch your EXOS-Electrum wallet by double clicking its icon, or some other method (launch from a terminal/console). This launches the Install Wizard. Its first question regards your method of connecting to a server. Although you can connect to a trusted server (and this is recommended for secure use), letting EXOS-Electrum decide on a server is a good beginner option. Click Next.
The next screen prompts you to name your wallet file with the text “This file does not exist.” The Wizard offers the default name
default_wallet. Accept it, then click Next.
The next screen offers a choice of three types of wallets, with the default set to “Standard wallet.” Leave this option selected then click Next.
The next screen asks about the kind of keystore to create. A keystore is the set of signing keys you’ll use to make EXOS token transactions, and is controlled by a seed. Leave the default option “Create a new seed” selected and click Next.
The next window displays your seed. The words displayed in your window should be different than that those in the figure below. Write your seed on a piece of paper. Don’t print it with a printer.
The next window asks you to type your seed. Click inside the text area and type the words of your seed. When you have entered the correct words, the Next button will become active. Click it.
EXOS-Electrum can, at your option, encrypt the copy of your seed stored to disk. In the event that your computer is attacked, an intruder obtaining EXOS-Electrum’s files will be unable to decrypt your seed. You may also encrypt the entire wallet file by selecting the “Encrypt wallet file” option. Doing so encrypts all wallet contents, not just the seed. This protects not only your tokens, but your privacy in the event of an attack. It is highly recommended to Encrypt your wallet and have it with password. Select a password you can remember (or write it in a piece of paper and place it in a safe place) that at least contains upper and lowercase letters, numbers and characters like $%!@, and that is at least 12-15 characters long (a longer password is usually better than a random password)
Wallets intended for experimentation and learning benefit little from encryption. For now, leave the password fields blank and click “Next.”
EXOS-Electrum advises that the latest version of the wallet is used. Select YES to be notified when a new version is available.
Funding Your Wallet
If you already keep EXOS tokens on a staking wallet, you may now transfer those funds into your EXOS-Electrum wallet. If you do, a very small transfer is recommended. Expect to make mistakes when learning EXOS-Electrum, especially if you’re new to EXOS. It’s far better to take your lumps when dealing with chump change than when your tokens are on the line.
To receive EXOS, you’ll need an address. Click on the Receive tab to obtain one. You can either scan the QR code or copy the receiving address to the clipboard and paste it into your withdrawal service.
The transaction will initially be marked as “unconfirmed” under the History tab, indicating that it has not yet been added to the block chain. A transaction added to the current block has one confirmation. A transaction added to the preceding block has two confirmations, and so on.
Adding a description to this payment will help you identify it later. To do so, double-click the Description field and add a descriptive label.
Sending EXOS can be made through the Send tab. Activate it by clicking. The “Pay to” field holds an EXOS token address of your intended payee, which can be manually entered or pasted from the clipboard. Adding a description will help you identify the payment later.
The total amount of the transaction is the sum of the sent amount and transaction fee. EXOS-Electrum issues a warning in the form of a red amount if the total transaction amount exceeds the wallet balance.
A fee is required to send any transaction. Whereas the banking system charges fees based on the amount being sent, EXOS charges fees based on the number of bytes needed to encode a transaction. The fee is the product of two terms: the transaction length, in bytes; and the market fee density. The fee density fluctuates with network transaction volume.
EXOS-Electrum allows the fee density to be adjusted by moving the slider below the transaction amount. Sliding left decreases fee density; sliding right increases it. The higher the fee density, the higher the total fee, and the more likely a transaction will be included within the next block. A transaction of low fee density can be delayed for hours, days, or simply not confirm at all.
It’s a good idea to review your payment before publishing it. Click the Preview button. A popup window shows the amount sent, the transaction length in bytes, the fee and fee density you’re paying, and source/destination addresses.
Make a Backup
An EXOS-Electrum seed controls the generation of all addresses and private keys. As such, it’s vital to keep a paper copy of your wallet seed in a safe place. If you followed this tutorial from the beginning, you should have already written your seed on a piece of paper. If not, now would be a good time to create a backup.
Access your wallet’s seed through the seed icon in the lower right of the main screen, or by choosing Seed from the Wallet menu. When prompted, enter the secure password you chose when setting up the EXOS-Electrum wallet.
Hand-copy the twelve words found in the box to a piece of paper and store it in a safe location. Remember, anyone who finds your seed can spend all of the funds in your wallet.
Additionally, a backup of your wallet, including any annotations you may have made, can be saved by choosing the Save Copy item from the File menu. This file stores the wallet’s encrypted seed along with any annotations. Restoring this backup will require the wallet password if you added one.
Testing Backup: Delete Your Wallet
The only thing needed to recover funds from an EXOS-Electrum wallet is its seed. The optional procedure below describes how.
Note that this procedure will erase all of your wallet data. It’s designed to simulate a system failure. Restoring your wallet proves that you can recover from catastrophic system failure without loss of EXOS. If you can’t recover, you’ll lose any EXOS currently stored on your wallet.
Before continuing, verify that your current wallet contains only a small amount of EXOS that you would not be upset about losing. Also verify that you have access to your seed in written form.
To get EXOS-Electrum to generate a new wallet, the old wallet data needs to be deleted. Begin by exiting EXOS-Electrum. Next, locate the program’s data directory based on your computer’s operating system.
Delete Wallet on Windows
2. Browse to
3. delete all files in the directory.
Delete Wallet on Mac and Linux
1. Open the Terminal;
2. Type “rm -rf ~/.exos-electrum/“.
To change the wallet’s password, select the Password option from the Wallet menu, or click the lock icon in the lower right of the main window. Enter and confirm a new secure password.
Should you forget your wallet’s password, all is not lost. Your funds can be restored in their entirety using the recovery procedure described in the previous section.
