Securing your wallet

Be careful with online services


You should be wary of any service designed to store your money online. Many exchanges and online wallets suffered from security breaches in the past and such services generally still do not provide enough insurance and security to be used to store money like a bank. Accordingly, you might want to use other types of DSFR wallets. Otherwise, you should choose such services very carefully. Additionally, using two-factor authentication is recommended.


Small amounts for everyday uses


A DSFR wallet is like a wallet with cash. If you wouldn't keep a thousand dollars in your pocket, you might want to have the same consideration for your DSFR wallet. In general, it is a good practice to keep only small amounts of DSFRs on your computer, mobile, or server for everyday uses and to keep the remaining part of your funds in a safer environment.


Backup your wallet


Stored in a safe place, a backup of your wallet can protect you against computer failures and many human mistakes. It can also allow you to recover your wallet after your mobile or computer was stolen if you keep your wallet encrypted.


Backup your entire wallet


Some wallets use many hidden private keys internally. If you only have a backup of the private keys for your visible DSFR addresses, you might not be able to recover a great part of your funds with your backup.


Encrypt online backups


Any backup that is stored online is highly vulnerable to theft. Even a computer that is connected to the Internet is vulnerable to malicious software. As such, encrypting any backup that is exposed to the network is a good security practice.


Use many secure locations


Single points of failure are bad for security. If your backup is not dependent of a single location, it is less likely that any bad event will prevent you to recover your wallet. You might also want to consider using different medias like USB keys, papers and CDs.


Make regular backups


You need to backup your wallet on a regular basis to make sure that all recent DSFR change addresses and all new DSFR addresses you created are included in your backup. However, all applications will be soon using wallets that only need to be backed up once.


Encrypt your wallet


Encrypting your wallet or your smartphone allows you to set a password for anyone trying to withdraw any funds. This helps protect against thieves, though it cannot protect against keylogging hardware or software.


Never forget your password


You should make sure you never forget the password or your funds will be permanently lost. Unlike your bank, there are very limited password recovery options with DSFR. In fact, you should be able to remember your password even after many years without using it. In doubt, you might want to keep a paper copy of your password in a safe place like a vault.


Use a strong password


Any password that contains only letters or recognizable words can be considered very weak and easy to break. A strong password must contain letters, numbers, punctuation marks and must be at least 16 characters long. The most secure passwords are those generated by programs designed specifically for that purpose. Strong passwords are usually harder to remember, so you should take care in memorizing it.


Offline wallet for savings


An offline wallet, also known as cold storage, provides the highest level of security for savings. It involves storing a wallet in a secured place that is not connected to the network. When done properly, it can offer a very good protection against computer vulnerabilities. Using an offline wallet in conjunction with backups and encryption is also a good practice. Here is an overview of some approaches.


Offline transaction signing


This approach involves having two computers sharing some parts of the same wallet. The first one must be disconnected from any network. It is the only one that holds the entire wallet and is able to sign transactions. The second computer is connected to the network and only has a watching wallet that can only create unsigned transactions. This way, you can securely issue new transactions with the following steps.


Create a new transaction on the online computer and save it on an USB key.

Sign the transaction with the offline computer.

Send the signed transaction with the online computer.

Because the computer that is connected to the network cannot sign transactions, it cannot be used to withdraw any funds if it is compromised. Armory can be used to do offline transaction signature.


Hardware wallets


Hardware wallets are the best balance between very high security and ease of use. These are little devices that are designed from the root to be a wallet and nothing else. No software can be installed on them, making them very secure against computer vulnerabilities and online thieves. Because they can allow backup, you can recover your funds if you lose the device.


Keep your software up to date
