subxt ·

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

⚠️ Health Warning ⚠️ considered alpha after recent changes, API still subject to change

See https://github.com/paritytech/subxt/issues/309 for an overview of outstanding issues.

Usage

See examples.

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 executable binary substrate at polkadot-v0.9.10 on your path.

This can be installed from source via cargo:

cargo install --git https://github.com/paritytech/substrate node-cli --tag=polkadot-v0.9.10 --force

Alternatives

substrate-api-client provides similar functionality.

Subxt Client

By default the client builder will connect to a full node via rpc. The subxt-client helps embedding a light client directly. It can also be used to embed a full node. This is especially useful for testing and ci.
