JsonRpc module
Property
Description
Default
BufferResponses
Buffer responses before sending them to client. This allows to set Content-Length in response instead of using Transfer-Encoding: chunked. This may degrade performance on big responses. Max buffered response size is 2GB, chunked responses can be bigger.
false
CallsFilterFilePath
A path to a file that contains a list of new-line separated approved JSON RPC calls
Data/jsonrpc.filter
Enabled
Defines whether the JSON RPC service is enabled on node startup. Configure host nad port if default values do not work for you.
false
EnabledModules
Defines which RPC modules should be enabled. Built in modules are: Admin, Baseline, Clique, Consensus, Db, Debug, Deposit, Erc20, Eth, Evm, Health Mev, NdmConsumer, NdmProvider, Net, Nft, Parity, Personal, Proof, Subscribe, Trace, TxPool, Vault, Web3.
[Eth, Subscribe, Trace, TxPool, Web3, Personal, Proof, Net, Parity, Health]
EthModuleConcurrentInstances
Number of concurrent instances for non-sharable calls (eth_call, eth_estimateGas, eth_getLogs, eth_newFilter, eth_newBlockFilter, eth_newPendingTransactionFilter, eth_uninstallFilter). This will limit load on the node CPU and IO to reasonable levels. If this limit is exceeded on Http calls 503 Service Unavailable will be returned along with Json RPC error. Defaults to number of logical processes.
FindLogBlockDepthLimit
Defines block depth when finding logs.
1000
GasCap
Gas limit for eth_call and eth_estimateGas
100000000
Host
Host for JSON RPC calls. Ensure the firewall is configured when enabling JSON RPC. If it does not work with 117.0.0.1 try something like 10.0.0.4 or 192.168.0.1
"127.0.0.1"
IpcUnixDomainSocketPath
The path to connect a unix domain socket over.
MaxRequestBodySize
Max HTTP request body size
30000000
Port
Port number for JSON RPC calls. Ensure the firewall is configured when enabling JSON RPC.
8545
ReportIntervalSeconds
Interval between the JSON RPC stats report log
300
RpcRecorderBaseFilePath
Base file path for diagnostic JSON RPC recorder.
"logs/rpc.{counter}.txt"
RpcRecorderState
Defines whether the JSON RPC diagnostic recording is enabled on node startup. Do not enable unless you are a DEV diagnosing issues with JSON RPC. Possible values: None/Request/Response/All.
None
Timeout
JSON RPC' timeout value given in milliseconds.
20000
WebSocketsPort
Port number for JSON RPC web sockets calls. By default same port is used as regular JSON RPC. Ensure the firewall is configured when enabling JSON RPC.
