Official Client for the Avail blockchain

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 goldberg -d ./output

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

Running Dev Chain

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

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

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

Kate RPC

To enable Kate RPC you need to pass --enable-kate-rpc flag when executing the binary.

./avail-node --enable-kate-rpc

Interact with the chain

You can find on this repository many example on how to interract 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
- Go examples
- Validium example implementation
