subxt · 
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.
- Install:
cargo install subxt-cli
- 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/polkadot-sdk staging-node-cli --force
