Hydra for Beginners

Quick guide to getting started

We'll begin with creating a secure wallet using the HYDRA Web Wallet which can be found at https://webwallet.hydrachain.org. Click 'Create from Mnemonic' and record the Mnemonic words on a piece of paper. Once you have confirmed your Mnemonic words you can then continue and reveal your private key. The Mnemonic words along with your private key and key file should be stored somewhere extremely safe such as written down on a piece of paper and locked in safe. After set up of a wallet client you will be able to proceed to the section where you can securely Import the private key into the HYDRA wallet.

Next we will download the HYDRA wallet client and blockchain node. Upon first installation and initialization, the software will generate a new and unique wallet for you, if you don't have one already. You can choose from the options below depending on your system type:

Please note that it is highly recommended NOT to stake HYDRA on a computer you use on a daily basis because this computer could be compromised without your knowledge.

For inexperienced users who are looking for a way to create a relatively safe staking environment, we highly recommend The "Staking in the cloud with Windows VPS in AWS" guide.

Windows installers:

32bit 64bit

Raspberry pi:



Ubuntu 18.04 Linux (Please follow THIS guide)

Ubuntu 20.04 Linux (Please follow THIS guide)

Aarch64 Linux

On Windows the Testnet (port 1334) and MainNet (port 3338) versions will be available in the start menu. It is recommended to open these ports in your operating system and on your router's port forwarding page. There is a tutorial on opening windows ports in this section. In Linux software you can create a directory called Hydra and place the zipped file here:

mkdir ~/Hydra
cd ~/Hydra/
wget -N https://github.com/Hydra-Chain/node/releases/download/hydra_v0.18.5/hydra-0.18.5-ubuntu18.04-x86_64-gnu.zip

Unzip the build:

unzip -o hydra-0.18.5-ubuntu18.04-x86_64-gnu.zip

The binaries will then be in ~/Hydra/bin/ where you can cd into

cd ~/Hydra/bin/

Either run the command-line daemon (omit '-testnet' if you want to connect to mainnet):

./hydrad -daemon -testnet

and call the daemon with:

./hydra-cli -testnet getinfo

Or you can run the GUI using:

./hydra-qt -testnet

Importing your private key to the wallet

After creating a wallet at https://webwallet.hydrachain.org/ and clicking 'Create from Mnemonic' and saving your key and Mnemonic information somewhere safe, there are several ways to import your key into the wallet. The most common is through the client interface:

To import your HYDRA private key on the wallet GUI click 'Help' and then 'Information window'

A new window will pop up where you can select 'Console' from above. Insert your key with 'importprivkey ' preceding it.

The wallet take some time to scan and import your new address

After scan has completed, 'null' will be displayed. This indicates that your import has been successful.

Your new HYDRA wallet has been imported

For safety it is recommended to encrypt and backup your wallet. Click 'Settings' and then 'Encrypt Wallet'

Set an extremely strong password and write it down somewhere safe so that you will be able to recover it later. You can use a password generator such as: https://www.lastpass.com/password-generator

Verify that you have backed up the password somewhere safe and click 'Yes'

The wallet will now close to finish the encryption process.

Please proceed to back up your new wallet by clicking 'File' and then 'Backup Wallet'. Save the file 'Wallet.dat' somewhere secure.

Back up the wallet to a secure place

Congratulations! Your HYDRA wallet should now be up and running and ready for staking rewards!
