Running Avail Node

Manually

To manually run the Avail Node, you'll need to have the following dependencies installed:

• Rust
• Substrate dependencies

After ensuring you have the dependencies installed, you can run the Avail Node using the following command:

mkdir -p output
cargo run --locked --release -- --chain mainnet -d ./output

This command compiles and runs the Avail Node connected to the Mainnet Network.

Supported Chains

Development

A development chain is typically used for testing and development purposes.

cargo run --locked --release -- --dev

Testnet New

cargo run --locked --release -- --chain new

Mainnet

cargo run --locked --release -- --chain mainnet

Docker

To run the Avail Node using Docker, follow these steps:

# Build the Docker image for the Avail Node:
docker build -t availnode -f ./dockerfiles/avail-node.Dockerfile .

# Create an output directory. Here the node's data will be stored.
mkdir output

# Run the Avail Node container:
docker run --rm -p 30333:30333 -p 9944:9944 -v ./output:/output availnode
# For SELinux
docker run --rm -p 30333:30333 -p 9944:9944 -v ./output:/output:z availnode

Running Dev Chain

There are instructions for running a development chain using Docker. A development chain is typically used for testing and development purposes.

# Build the Docker image for the Avail Node:
docker build -t availnode -f ./dockerfiles/avail-node.Dockerfile .

# Create an output directory. Here the node's data will be stored.

    Enable Kate RPC

--enable-kate-rpc-metrics
    Enable Kate RPC Metrics

--kate-max-cells-size <KATE_MAX_CELLS_SIZE>
    The maximum number of cells that can be requested in one go.
    
    Max size cannot exceed 10_000
    
    [default: 64]

Interact with the chain

You can find on this repository many example on how to interact with any avail chain.

• In the avail-js folder, you will find our wrapper for polkadot js including multiple helpers.
  • The example folder contains some examples using node-js and an example web app to setup the extension.
• In the avail-subxt folder, you will find our fork of subxt with some example on usage.
• In the examples folders you will find examples for:
  • Deno examples
