Availup

To run an Avail light client, simply run the following command:

curl -sL1 avail.sh | bash

or, with wget:

wget --secure-protocol=TLSv1_2 -q -O - avail.sh | bash

You can pass additional flags to the script like:

curl -sL1 avail.sh | bash -s -- --network turing

Currently available flags are:

• network: can be one of the following: [mainnet, turing, local]
• config: path to the configuration file, availup will generate a config if this flag is not specified
  • This flag is always required when running a local testnet
• config_url: URL to a valid YAML configuration file, availup will download the config if this flag is specified
  • If the configuration is invalid, the script will exit
  • This flag will only work with mainnet configurations
• identity: path to the identity file, availup will generate a config if this flag is not specified
  • It is important to keep your identity file safe!
• app_id: application ID to run the light client (defaults to 0)
  • It is recommended to not change this flag unless you require the app-specific mode.
• upgrade: takes y and yes as valid arguments, indicating that the avail-light binary should be upgraded
  • Using this flag wipes your existing data and config, use with caution! This flag does not guarantee that the binary will be upgraded.
• force_wsl: takes y and yes as valid arguments, the script exits on WSL systems by default. This flag can removed in the future.

You can use a custom config by passing it to availup as a flag:

# create the config:
touch ~/config.yml
# edit the config:
nano ~/config.yml
# and rerunning the script:
curl -sL1 avail.sh | bash -s -- --config ~/config.yml

⚠️ It is not recommended to modify the default config stored in ~/.avail/config/config.yml as that gets wiped on each run.

If you have a seed phrase that you'd like to use instead of the generated one, you can modify ~/.avail/identity/identity.toml, alternatively, you can pass it as a flag:

# edit default identity
nano ~/.avail/identity/identity.toml
# the script picks up the new identity automatically:
curl -sL1 avail.sh | bash
# create a new identity
touch ~/identity.toml
nano ~/identity.toml
# the script uses the identity at the path
curl -sL1 avail.sh | bash -s -- --identity ~/identity.toml

ℹ️ The script persists your identity file between runs. Deleting the file will cause a new one to be generated on the next run.

Alternatively, you can pass a specific application ID with availup:

rm ~/.avail/turing/config.yml
# and rerunning the script with flags:
curl -sL1 avail.sh | bash -s -- --app_id 1

ℹ️ Adding an app ID disables the LC mode and runs your client in an app-specific mode, this might not be your intention.

In availup, binary upgrades are enabled by default to ensure you always have the latest supported version. In order to skip default upgrades you can simply pass the --upgrade flag like:

curl -sL1 avail.sh | bash -s -- --upgrade n

ℹ️ Upgrading the LC only works if the binary was installed with the latest availup script or cargo. If default updates are skipped, everytime the user will be prompted for a permission to upgrade once a new release is made available.

To run the light client on WSL systems, use the --force_wsl flag like:

curl -sL1 avail.sh | bash -s -- --force_wsl y

ℹ️ Running this flag on any other system does nothing.

To load a configuration from a URL, use the --config_url flag like:

curl -sL1 avail.sh | bash -s -- --config_url https://raw.githubusercontent.com/availproject/availup/main/configs/sophon.yml

ℹ️ The configuration file must be a valid YAML file, otherwise the script will exit.
