How to run an Avail node

There are two main ways of running an Avail node:

  1. By running a pre-built binary.
  2. By building from source
  3. By running a pre-built image using Docker

  1. Go to the Avail node GitHub releases page . There you will see a lot of pre-built binaries for each version of the Avail node.

  2. Please download the binary suitable from your system, of the latest version. You can do this using the GUI or by running the following command in your terminal:

curl -L -O https://github.com/availproject/avail/releases/download/<LATEST-AVAIL-NODE-VERSION>/<YOUR-SYSTEM-SPECIFIC-BINARY>.tar.gz
  1. Extract the downloaded file by opening a terminal in the location of the downloaded file and using the following command:
tar -xzvf <YOUR-SYSTEM-SPECIFIC-BINARY>.tar.gz

Your terminal should now look something like this:


Extracted Avail node binary

  • The file in red is what we downloaded to our system.
  • The file in green is the extracted binary.
  1. Once extracted, you will see a pre-built, executable binary named avail-node in the same directory. You can run this binary using the following command:
./avail-node --name a-random-name --chain mainnet -d ./output
  1. Your terminal output should look something like this:

Your node will also appear on the Avail Telemetry site , listed under the “Node name” from the node command output. Be sure to select the appropriate network tab at the top to view your node’s status.

Additional configs

The Avail node is a highly customizable piece of software. You can fetch a list of supported commands and flags using:

./avail-node --help

Alternatively, you can check out this notion page .

Please note that the notion page may not always be updated. The best way to reliably get the latest config options will be ./avail-node --help.
