Running the Server

Learn how to run and setup the JSON-RPC server on Ethermint. {synopsis}

Enable Server

To enable RPC server use the following flag (set to true by default).

ethermintd start --json-rpc.enable

Defining Namespaces

Eth,Net and Web3 namespaces are enabled by default. In order to enable other namespaces use flag --json-rpc.api.

ethermintd start --json-rpc.api eth,txpool,personal,net,debug,web3,miner

Set a Gas Cap

eth_call and eth_estimateGas define a global gas cap over rpc for DoS protection. You can override the default gas cap value of 25,000,000 by passing a custom value when starting the node:

# set gas cap to 85M
ethermintd start --json-rpc.gas-cap 85000000000

# set gas cap to infinite (=0)
ethermintd start --json-rpc.gas-cap 0

CORS

If accessing the RPC from a browser, CORS will need to be enabled with the appropriate domain set. Otherwise, JavaScript calls are limit by the same-origin policy and requests will fail:

ethermintd start --json-rpc.enable-unsafe-cors
