delta Domain SDK

The delta_domain_sdk provides the framework for building and running a domain on the delta network. Import the crate to get core types like vaults and addresses, support for user-level transactions such as debit allowances and token mints, and most importantly the Domain struct to run your domain and connect to the base layer.

Architecture​

The SDK's main entry point is Domain, which provides three components:

  • runner — launches the domain's event loop
  • client — performs actions (apply, submit, prove)
  • views — read-only access to state and SDLs
use delta_domain_sdk::{Domain, Config};

let config = Config::load()?;
let Domain { runner, client, views } = Domain::from_config(config)
    .build()
    .await?;

runner.run_in_background().await?;

admin-apiExposes the admin API for SDL management

Next Steps​

There are several paths to start building with the SDK. You can explore the example domain to see a working implementation, then copy and modify it to fit your needs. Alternatively, you can build a domain from scratch using the SDK primitives directly.
