* WIP EncodeAsType and DecodeAsType * remove silly cli experiment code * Get things finally compiling with EncodeAsType and DecodeAsType * update codegen test and WrapperKeepOpaque proper impl (in case it shows up in codegen) * fix tests * accomodate scale-value changes * starting to migrate to EncodeAsType/DecodeAsType * static event decoding and tx encoding to use DecodeAsFields/EncodeAsFields * some tidy up and add decode(skip) attrs where needed * fix root event decoding * #[codec(skip)] will do, and combine map_key stuff into storage_address since it's all specific to that * fmt and clippy * update Cargo.lock * remove patched scale-encode * bump scale-encode to 0.1 and remove unused dep in testing crate * update deps and use released scale-decode * update scale-value to latest to remove git branch * Apply suggestions from code review Co-authored-by: Alexandru Vasile <60601340+lexnv@users.noreply.github.com> * remove sorting in derives/attr generation; spit them out in order given * re-add derive sorting; it's a hashmap * StaticTxPayload and DynamicTxPayload rolled into single Payload struct * StaticStorageAddress and DynamicStorageAddress into single Address struct * Fix storage address byte retrieval * StaticConstantAddress and DynamicConstantAddress => Address * Simplify storage codegen to fix test * Add comments * Alias to RuntimeEvent rather than making another, and prep for substituting call type * remove unnecessary clone * Fix docs and failing UI test * root_bytes -> to_root_bytes * document error case in StorageClient::address_bytes() --------- Co-authored-by: Alexandru Vasile <60601340+lexnv@users.noreply.github.com>
subxt · 
A library to submit extrinsics to a substrate node via RPC.
Usage
Take a look in the examples folder for various subxt usage examples.
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/substrate node-cli --force
Real world usage

- 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
subxtfor allowing developers to conduct End-to-End testing of their contracts.
