The run command used to run a node.

Fields

validator: bool

Enable validator mode.

The node will be started with the authority role and actively participate in any consensus task that it can (e.g. depending on availability of local keys).

no_grandpa: bool

Disable GRANDPA.

Disables voter when running in validator mode, otherwise disable the GRANDPA observer.

rpc_external: bool

Listen to all RPC interfaces (default: local).

Not all RPC methods are safe to be exposed publicly.

Use an RPC proxy server to filter out dangerous methods. More details: https://docs.substrate.io/build/remote-procedure-calls/#public-rpc-interfaces.

Use --unsafe-rpc-external to suppress the warning if you understand the risks.

unsafe_rpc_external: bool

Listen to all RPC interfaces.

Same as --rpc-external.

rpc_methods: RpcMethods

RPC methods to expose.

rpc_rate_limit: Option<NonZeroU32>

RPC rate limiting (calls/minute) for each connection.

This is disabled by default.

For example --rpc-rate-limit 10 will maximum allow 10 calls per minute per connection.

rpc_rate_limit_whitelisted_ips: Vec<IpNetwork>

Disable RPC rate limiting for certain ip addresses.

Each IP address must be in CIDR notation such as 1.2.3.4/24.

rpc_rate_limit_trust_proxy_headers: bool

Trust proxy headers for disable rate limiting.

By default the rpc server will not trust headers such X-Real-IP, X-Forwarded-For and Forwarded and this option will make the rpc server to trust these headers.

For instance this may be secure if the rpc server is behind a reverse proxy and that the proxy always sets these headers.

rpc_max_request_size: u32

Set the maximum RPC request payload size for both HTTP and WS in megabytes.

rpc_max_response_size: u32

Set the maximum RPC response payload size for both HTTP and WS in megabytes.

rpc_max_subscriptions_per_connection: u32

Set the maximum concurrent subscriptions per connection.

rpc_port: Option<u16>

Specify JSON-RPC server TCP port.

rpc_max_connections: u32

Maximum number of RPC server connections.

rpc_message_buffer_capacity_per_connection: u32

The number of messages the RPC server is allowed to keep in memory.

If the buffer becomes full then the server will not process new messages until the connected client start reading the underlying messages.

This applies per connection which includes both JSON-RPC methods calls and subscriptions.

rpc_disable_batch_requests: bool

Disable RPC batch requests

rpc_max_batch_request_len: Option<u32>

Limit the max length per RPC batch request

rpc_cors: Option<Cors>

Specify browser origins allowed to access the HTTP & WS RPC servers.

A comma-separated list of origins (protocol://domain or special null value). Value of all will disable origin validation. Default is to allow localhost and https://polkadot.js.org origins. When running in --dev mode the default is to allow all origins.

name: Option<String>

The human-readable name for this node.

It’s used as network node name.

telemetry_params: TelemetryParams

prometheus_params: PrometheusParams

runtime_params: RuntimeParams

offchain_worker_params: OffchainWorkerParams

shared_params: SharedParams

import_params: ImportParams

network_params: NetworkParams

pool_config: TransactionPoolParams

keystore_params: KeystoreParams

alice: bool

Shortcut for --name Alice --validator.

Shortcut for --name Bob --validator.

Session keys for Bob are added to keystore.

charlie: bool

Shortcut for --name Charlie --validator.

Session keys for Charlie are added to keystore.

dave: bool

Shortcut for --name Dave --validator.

eve: bool

Shortcut for --name Eve --validator.

Session keys for Eve are added to keystore.

ferdie: bool

Shortcut for --name Ferdie --validator.

Session keys for Ferdie are added to keystore.

one: bool

Shortcut for --name One --validator.

Session keys for One are added to keystore.

two: bool

Shortcut for --name Two --validator.

Session keys for Two are added to keystore.

force_authoring: bool

Enable authoring even when offline.

tmp: bool

Run a temporary node.

A temporary directory will be created to store the configuration and will be deleted at the end of the process.

Note: the directory is random per process execution. This directory is used as base path which includes: database, node key and keystore.

When --dev is given and no explicit --base-path, this option is implied.
