	let runtime_version =
		pezkuwi_subxt::client::RuntimeVersion { spec_version: 9370, transaction_version: 20 };

	// 3. Metadata (I'll load it from the downloaded metadata, but you can use `subxt metadata >
	//    file.scale` to download it):
	let metadata = {
		let bytes = std::fs::read("./artifacts/pezkuwi_metadata_small.scale").unwrap();
