Merge's wallet is made up of two halves. One is the public, shareable part called the public key. The other is the private part that is required for spending the stored MERGE in that wallet. If you want to receive MERGE into your wallet, you should provide one of your public addresses. Think of the public part of Merge's wallet as your email address and the private part as the password to that email address: you can share the email address freely, but not the password.

Encrypting your wallet is a great idea to prevent other people using your computer to steal your money or your wallet.dat file. Please don’t forget the encryption's password. If you lose it, you can’t access your funds anymore and we will not be able to help.
In your Merge wallet, click on Settings > Encrypt Wallet... and add your password (passphrase) in order to encrypt your wallet. A confirmation plus the encryption process (can take a few minutes) will follow:
This action is very important. Don't forget to back up your wallet.dat!
Always keep backups in multiple places so your money is safe in case you lose access to the computer.
Every time you create a new receiving address, you must backup your wallet.dat file or you risk losing your newly received funds!
Whenever a change is made on your Merge wallet (ex. creating a new address for a masternode), an automatic backup will be made. They can be found here:
In your Merge wallet, click and follow the steps on File > Backup Wallet...
Make sure your Merge wallet is closed.
Go to your Merge wallet folder:
Copy the wallet.dat file and save it in a secure location. Remember: if your wallet is unencrypted and it gets stolen, your MERGE is not safe! You can backup the merge.conf and masternode.conf files as well.
In your Merge wallet, go to Tools > Debug console:
The debug console window will appear:
Type into the command line at the bottom:
dumpprivkey (paste your MERGE address here, leaving a space between the command and the address)
The wallet address looks similar to this “MGjMS1zhYjfMKKGcexcPkkz3nb7VH3apBP”. Every MERGE address starts with M.
Press “Enter” with the keyboard. The wallet address and private key will appear in the console window.
Remember to leave a space between the dumpprivkey command and the MERGE address.
Write down, print and/or save the private key. This will help you recovering your funds from that MERGE address anywhere regardless whether you have lost your computer or password.
Each MERGE address in the wallet has a different private key so you must repeat this for each one.
NEVER GIVE ANYONE YOUR PRIVATE KEYS!
Keep your funds safe by saving your private keys.
