subxt · build Latest Version Documentation

A library to submit extrinsics to a substrate node via RPC.

Usage

Take a look in the examples folder or the examples folder for various smaller or larger subxt usage examples, or read the guide to learn more.

Downloading metadata from a Substrate node

Use the subxt-cli tool to download the metadata for your target runtime from a node.

  1. Install:
cargo install subxt-cli
  1. Save the encoded metadata to a file:
subxt metadata -f bytes > metadata.scale

This defaults to querying the metadata of a locally running node on the default http://localhost:9933/. If querying a different node then the metadata command accepts a --url argument.

Subxt Documentation

For more details regarding utilizing subxt, please visit the documentation.

Integration Testing

Most tests require a running substrate node to communicate with. This is done by spawning an instance of the substrate node per test. It requires an up-to-date substrate executable on your path.

This can be installed from source via cargo:

cargo install --git https://github.com/paritytech/substrate node-cli --force

Real world usage

Please add your project to this list via a PR.

  • cargo-contract CLI for interacting with Wasm smart contracts.
  • xcm-cli CLI for submitting XCM messages.
  • phala-pherry The relayer between Phala blockchain and the off-chain Secure workers.
  • crunch CLI to claim staking rewards in batch every Era or X hours for substrate-based chains.
  • interbtc-clients Client implementations for the interBTC parachain; notably the Vault / Relayer and Oracle.
  • tidext Tidechain client with Stronghold signer.
  • staking-miner-v2 Submit NPos election solutions and get rewards.
  • polkadot-introspector Tools for monitoring Polkadot nodes.
  • ink! Smart contract language that uses subxt for allowing developers to conduct End-to-End testing of their contracts.
