Startup Arguments
The full lists of startup arguments you may use to configure your Local Gateway.
The following arguments can be used to configure your Local Gateway, regardless of the installation method chosen
Required Gateway Arguments
enodes
Enode of the blockchain node
enode://<node_public_key>@<ip>:<port>
Optional for Enterprise-Elite users or above
multiaddr
Node address using p2p nodes format
/ip4/54.167.71.57/tcp/13000/p2p/16Uiu2HAkvxQyb62x55RrhxxYHm1ZJFMFFFhCZ67YVmTcS6kJwqQR
Optional for non-Ethereum network or gateway working without blockchain node
multiaddr has replaced enr as the argument to indicate the node address because it is human-readable. It has the following format:
/ip4/<IPv4_NETWORK_ADDRESS>/tcp/<LISTENING_PORT>/p2p/<NODE_ID>
multiaddr and enr cannot be used at the same time because they represent the same node.
Optional Gateway Arguments
blockchain-network
Blockchain network the gateway will connect to
Mainnet, BSC-Mainnet
Mainnet
BSC-Mainnet
private-key
Private key for encrypted communication with Ethereum node
This argument is optional, and the Gateway will generate a random private key if one is not provide.

all-txs
Set this flag to propagate all transactions from the BDN to the connected node (warning: may result in worse performance and propagation times).
false
true
enable-blockchain-rpc
Set this flag to enable the gateway to serve as a proxy for your blockchain RPC node.
Find a detailed guide to using this feature here.
false
true
tx-include-sender-in-feed
Set this flag if you want extract sender of the transaction into Websocket or gRPC feed.
From field is deprecated and will be removed in the future. This made to improve performance and shift responsibility to feed client. In versions up to v2.128.14.1 it is true by default, after it will be false, which means you need to set it explicitly if you want to get from.
