Avail Node Tutorial

Changing Node Wallet

1. Login to your Avail Node via SSH (PuTTY, Termius, etc.)

2. Run the following to backup the current configuration:

   • {APP_NAME} is the name you selected for your app chain

   cd ~/.madara/app-chains/{APP_NAME}
   cp da-config.json da-config-backup.json

3. edit the da-config.json file with editor of your choice (nano, vim, etc.)

   nano da-config.json

   • Change the seed and address values to the new wallet's values.

   {"ws_provider":"wss://goldberg.avail.tools:443/ws", "mode":"sovereign", "seed": "DESIRED WALLET'S SEED PHRASE","app_id":0,"address":"DESIRED WALLET'S ADDRESS"}

   • Note: you can enter the mnemonic 12-word phrase as your seed as well.
   • example: "seed": "jelly fun printer ... serve"

4. Save and exit the editor. for nano: Ctrl+X -> Y -> Enter

Rerun the node with the updated Config

5. Run the following command to go to the madara directory

   cd ~/madara-cli/target/release

6. Kill the running node process on screen session

   6.1. List the running sessions:

   screen -ls

   • Outputs something like this

   # There are screens on:
   #   53432.roller    (02/10/24 14:53:50)     (Detached)
   #   ...

   6.2 Kill the process with the session id, example 53432.roller. change based on your output.

   screen -XS 53432.roller quit

   • alternatively you can kill all the screen sessions instead of 6.1. and 6.2. by running killall screen

7. After killing the node process, Start a new screen session:

   screen -s ANYNAME

   • ANYNAME can be anything like roller, node, your app name, etc.

8. Run the node again:

   ./madara run

   • choose your app_name, then Y and it should continue importing the blocks where you left off.

9. To run the explorer too, switch to a new screen by pressing Ctrl+A then D and run:

   ./madara explorer --host=IPADDRESS

   • Replace IPADDRESS with your IP Address.

10. Everything should be running now. No need to change anything else!
