Prerequisites

Base Dependencies​

To complete this tutorial and work with the delta Domain SDK, you'll need the following:

delta Dependencies​

Our testnet is currently available to trusted partners. The delta team should have provided you with the following:

  • An authentication token for delta's crate registry
  • A pre-seeded base layer keypair and shard ID
  • A delta testnet validator endpoint

If you have not yet been onboarded by the delta team and provided with these resources, please request access or reach out to your delta contact.

Cargo Configuration​

To add the delta registry to your global cargo configuration, the following lines should be added to your ~/.cargo/config.toml file:

[registries.delta]
index = "sparse+https://crates.repyhlabs.dev/api/v1/crates/"
credential-provider = ["cargo:token"]
token = "your authentication token"

Alternatively, you can log in temporarily using only the terminal by running

cargo login --registry delta \
  --index "sparse+https://crates.repyhlabs.dev/api/v1/crates/" \
  <your-authentication-token>

Once access the delta crates is configured and base dependencies are installed, you can start working with the delta testnet and example tools.
