# JSON-RPC Server
Check the JSON-RPC methods and namespaces supported on Ethermint. {synopsis}
## Pre-requisite Readings
- [Ethereum JSON-RPC ](https://eth.wiki/json-rpc/API ) {prereq}
- [Geth JSON-RPC APIs ](https://geth.ethereum.org/docs/rpc/server ) {prereq}
2021-07-26 11:15:55 +00:00
## JSON-RPC Server
To enable RPC server use the following flag (set to true by default).
```
ethermintd start --evm-rpc.enable
```
2021-08-03 16:35:04 +00:00
`Eth` ,`Net` and `Web3` namespaces are enabled by default. In order to enable other namespaces use flag `--evm-rpc.api` .
2021-07-26 11:15:55 +00:00
```
ethermintd start --evm-rpc.api eth,txpool,personal,net,debug,web3
```

```
### eth_sign
The sign method calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).
By adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
::: warning
the address to sign with must be unlocked.
:::
#### Parameters
- Account Address
- Message to sign
```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x3b7252d007059ffc82d16d022da3cbf9992d2f70", "0xdeadbeaf"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

```
### eth_sendTransaction
Sends transaction from given account to a given account.
#### Parameters
- Object containing:
from: DATA, 20 Bytes - The address the transaction is send from.
to: DATA, 20 Bytes - (optional when creating new contract) The address the transaction is directed to.
gas: QUANTITY - (optional, default: 90000) Integer of the gas provided for the transaction execution. It will return unused gas.
gasPrice: QUANTITY - (optional, default: To-Be-Determined) Integer of the gasPrice used for each paid gas
value: QUANTITY - value sent with this transaction
data: DATA - The compiled code of a contract OR the hash of the invoked method signature and encoded parameters. For details see Ethereum Contract ABI
nonce: QUANTITY - (optional) Integer of a nonce. This allows to overwrite your own pending transactions that use the same nonce.
```json

You can get signed transaction data using the personal_sign method
#### Parameters
- The signed transaction data

### eth_call
Executes a new message call immediately without creating a transaction on the block chain.
#### Parameters
- Object containing:
from: DATA, 20 Bytes - (optional) The address the transaction is sent from.
to: DATA, 20 Bytes - The address the transaction is directed to.
gas: QUANTITY - gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
gasPrice: QUANTITY - gasPrice used for each paid gas
value: QUANTITY - value sent with this transaction
data: DATA - (optional) Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation
- Block number

### eth_getFilterLogs
Polling method for a filter, which returns an array of logs which occurred since last poll.
#### Parameters
- The filter id
```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getFilterLogs","params":["0x127e9eca4f7751fb4e5cb5291ad8b455"],"id":1}' -H "Content-Type: application/json" http://localhost:8545
// Result
{"jsonrpc":"2.0","id":1,"error":{"code":-32000,"message":"filter 0x35b64c227ce30e84fc5c7bd347be380e doesn't have a LogsSubscription type: got 5"}}
``` -->
### eth_getLogs
Returns an array of all logs matching a given filter object.
#### Parameters
- Object containing:
fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.
topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with “or” options.
blockhash: (optional, future) With the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in in the filter criteria, then neither fromBlock nor toBlock are allowed.
