All phases of Avail's unification drop have now ended, πŸ‘‰πŸ‘‰ check out this page πŸ‘ˆπŸ‘ˆ for more information.


Get Started with Avail

Start Operating

To run an Avail light client, simply run this command powered by availup (opens in a new tab):

curl -sL1 | bash

And that's it!

If you're seeking more control over the configuration or are interested in running a full node, check out the deployment guides below.

Start Building

The Avail API offers a robust set of features that enable application developers to interact seamlessly with the Avail network. This guide provides a curated list of example code snippets in JavaScript/TypeScript, Rust, and Go. These examples cover essential tasks such as establishing a connection to a local node, querying data from the network, and executing transactions on the blockchain.

Before diving into the examples, ensure you have a local Avail node running or configure your settings to align with an existing network.

Detailed instructions on how to execute these examples are available in the Avail GitHub repository:

Sample Workflow

Follow these steps to understand a sample end-to-end flow of data availability in Avail. Examples are provided for JavaScript, Go, and Rust.

Step 1: Establishing Connection

Before you can interact with the Avail network, you need to establish a connection to a node.

Step 2: Submitting Data

Once connected, the next step is to submit data to the network. This could be any blob of data that you want to make available.

Step 3: Dispatching Data Root (Optional)

If you need to dispatch the data root, you can do so at this stage. This is optional and depends on your use case.

Step 4: Querying Data and Proofs

After submitting your data, you might want to query it to ensure it's been properly stored and is retrievable.

Step 5: Monitoring and Metrics

Finally, you can monitor the network and your data by listening for new blocks and other metrics.
