Struct CommonChainArgs 

pub struct CommonChainArgs {
    pub config: Option<PathBuf>,
    pub rpc_url: Option<String>,
    pub chain_id: Option<u64>,
    pub keystore: Option<PathBuf>,

}

Blockchain coordinates + keys shared by every on-chain command, flattened into each command’s args so they expose an identical flag group and can’t drift. Each field is taken from a flag when present, otherwise the [blockchain] / [identity] tables of the TOML config (the same file the daemon reads). ChainArgs / PublishChainArgs layer their contract-address flags on top of this; the shared resolver (chain_ctx::resolve_common) reads these fields so the flag > config > default precedence lives in one place.

Fields

config: Option<PathBuf>

Path to the TOML config file supplying [blockchain] / [identity] fields not passed as flags. Takes precedence over the top-level decdn --config; falls through to ~/.decdn/node.toml.

rpc_url: Option<String>

JSON-RPC endpoint URL. Overrides blockchain.rpc_url.

chain_id: Option<u64>

EIP-712 chainId for signing domains. Overrides blockchain.chain_id; defaults to Arbitrum Sepolia. Must match the target contract deployment’s chain or signatures are rejected on-chain. The publish and setup commands additionally read the RPC’s own chain id and refuse to submit on a mismatch; the other on-chain commands do not.

keystore: Option<PathBuf>

Ethereum keystore file. Overrides blockchain.eth_keystore; defaults to <data_dir>/keystore.json.

data_dir: Option<PathBuf>

Data directory holding node.secret. Overrides identity.data_dir; defaults to ~/.decdn.

keystore_password_file: Option<PathBuf>

File whose contents are the keystore password. Consulted after the DECDN_KEYSTORE_PASSWORD env var and before an interactive prompt on a TTY. A single trailing newline is stripped; a file that is empty after that strip is a deliberate empty password, not an absent source. A path that does not exist falls through; one that exists but cannot be read is an error.

dry_run: bool

Build and print what would be submitted without sending any transaction.

json: bool

Emit the result as JSON instead of human-readable key=value lines.

Trait Implementations

impl Args for CommonChainArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut
