Struct AddCodeSubstituteCmd 

pub struct AddCodeSubstituteCmd {
    pub input_chain_spec: PathBuf,
    pub runtime: PathBuf,
    pub block_height: u64,
}

Add a code substitute in the chain spec.

The codeSubstitute object of the chain spec will be updated with the block height as key and runtime code as value. This operation supports both plain and raw formats. The codeSubstitute field instructs the node to use the provided runtime code at the given block height. This is useful when the chain can not progress on its own due to a bug that prevents block-building.

Note: For parachains, the validation function on the relaychain needs to be adjusted too, otherwise blocks built using the substituted parachain runtime will be rejected.

Fields

input_chain_spec: PathBuf

Chain spec to be updated.

runtime: PathBuf

New runtime wasm blob that should replace the existing code.

block_height: u64

The block height at which the code should be substituted.
