Node on Hetzner server

A guide for installing your Swingby node on Hetzner dedicated servers.

Getting Started guide to deploy Swingby Nodes in the Hetzner server

  1. 1.
    Create your Hetzner account and Order an AX-61-NVMe server
  2. 2.
    Setup your telegram BOT with following this readme: =>
  3. 3.
    Install your telegram BOT to your AX-61-NVMe server.
  4. 4.
    Bonding your Swingby Tokens on DAO portal: =>

Why we choose the Hetzner server? The Hetzner Cloud is one of the most cost-effective servers for running swingby nodes in your local infrastructure package. I have a root user who has RSA key authentication as a bootstrap. Disk mounts are basically mounted at / (root). Basically, telegram BOT uses root to connect to the server, so this choice is much easier than other cloud services.

Step 1. Generate your SSH private key [on local machine]

$ git clone && cd node-installer
$ ssh-keygen -t rsa -b 4096 -f ./data/ssh_key
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): <- (should be empty)
There are 2 files are generated on your local machine.
  • ./data/ssh_key <- (this is a SSH private key, it should be backed up)
  • ./data/ <- (this is a SSH pubkey for access to your server)
Also, you have to grant permissions with this command.
$ chmod 600 ./data/ssh_key

Step 2. Order your Hetzner account and Order an AX-61-NVMe server

AX-61 NVMe has a 1.92TB disk (RAID1), The Swingby node requires 1.3TB for the BTC-ETH bridge, 1.4TB for the BTC-BSC bridge (full installation using with your local_infura ) local_infura means your node will be connected to self-hosting Geth (BSC) and 2 blockbooks containers, therefore, your server has to total 6 containers running. (bitcoind, geth/bsc, blockbook-btc, blockbook-eth/bsc, swingby node)

Step 3. Setup your Server with your generated SSH public key

  • You can put ./data/ file texts into the server setup interface.

Step 4. Make a new directory on your server [on your server]

  • you have to make a new directory
    • /var/swingby
$ ssh -i ./data/ssh_key [email protected]<YOUR_SERVER_IP> "mkdir /var/swingby"

Step 5. Setup your telegram BOT [on local machine]

  • (Prerequisite: you have to create a telegram BOT via the @Botfather and obtain a BOT_TOKEN. Here's a tutorial)
  • COPY and PASTE to your command line like this
$ export BOT_TOKEN=1716737416:ACEoPHFFlCAGiD2xGQl3Zk_wCoOD9P3Igk0

Step 6. Install Docker to your local machine

Install Docker from to your local machine.
Example of Docker for MAC OSX

Step 7. Run your telegram BOT on your [on local machine]

$ chmod +x scripts/ && scripts/

Step 8. Talk to your telegram BOT with /start

Step 9. Set your IP address and login username

  • Hetzner cloud always uses root to log in via SSH session. then, your can going forward with type 'none'

Step 10. Install your telegram BOT to your server

  • /setup_your_bot
    • This command will start the process of move out your telegram BOT to your server
Finally, you are ready to install on the Swingby node!!
