feat: add avail plugin

[robin-rrt]

Relates to:

N/A

Risks

Low. The main implementation risk is that the Plugin doesn't work as intended.

Background

What does this PR do?

Avail aims to accelerate Web3's unification using its cutting-edge modular technology stack, which combines data availability, aggregation, and shared security.

In this version, the transfer and submitData actions are supported.

Multiple L2s are working with Avail to meet their data availability and interoperability needs.

What kind of change is this?

Features (non-breaking change which adds functionality)

Documentation changes needed?

Since Avail is a Substrate based network, and not EVM-compatible (cannot work with plugin-evm), it requires some docs to show how to submit data and transfer tokens. I have updated the documentation accordingly in the README for the plugin.

Testing

Where should a reviewer start?

Most of the changes are in plugin-avail

Detailed testing steps

• In .env you should set the value for AVAIL_ADDRESS (this is the public address for the agent account) and AVAIL_SEED (seed phrase for the same account).
• Transfer AVAIL
  • To test transfer function, you need tokens in your Avail account. On testnet, you can use the Avail Faucet. If you need more please ping me, and I can send it over.
  • Run the agent and prompt it with: "send 1 AVAIL to <any other Avail account> " - e.g. send 1 AVAIL to 5GWbvXjefEvXXETtKQH7YBsUaPc379KAQATW1eqeJT26cbsK
  • Assuming everything goes smoothly the agent returns with the Tx Hash, and Block Hash. The tx hash can be checked on the Avail block explorer at https://avail-turing.subscan.io/
• Submit Data
  • To test data submission, you need tokens in your Avail account to pay fees. On testnet, you can use the Avail Faucet. If you need more please ping me, and I can send it over.
  • Run the agent and prompt it with: "Submit the following data to Avail <DATA>" - e.g. Submit the following data to Avail "Hello World!"
  • Assuming everything goes smoothly the agent returns with the Tx Hash, and Block Hash.

Hey @odilitime checking in if you please review and merge the plugin

[odilitime]

You don’t need to do the docs, the label is for our docs team. Though have a README.md in the root of the plugin explaining what it does and what settings are available is always helpful.

please work on your conflicts and we’ll look at merging it Monday
