ChainSpec

✓ use sc_chain_spec::ChainSpec;

Loads a chain specification from a JSON file and prints the chain name.

use sc_chain_spec::ChainSpec; fn main() { // Example: loading a chain spec from a JSON file let spec = ChainSpec::from_json_file("chain_spec.json").expect("Failed to load chain spec"); println!("Chain name: {}", spec.name()); }

Debug

Known issues

breakingChain spec format can change between Substrate versions; loading an incompatible spec may panic.

fix

Ensure the chain spec JSON matches the version of `sc-chain-spec` you are using. Regenerate specs with the same Substrate version.

affects: >= 50.0.0
