### `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.
:::

- 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_getFilterLogs

Polling method for a filter, which returns an array of logs which occurred since last poll.

#### Parameters

- The filter id

```json
// Request

``` -->

### `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.

## Miner Methods

### `miner_setGasPrice`

Sets the minimal gas price used to accept transactions. Any transaction below this limit is excluded from the validator block proposal process.

This method requires a `node` restart after being called because it changes the configuration file.

Make sure your `ethermintd start` call is not using the flag `minimum-gas-prices` because this value will be used instead of the one set on the configuration file.

#### Parameters

- Hex Gas Price

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasPrice","params":["0x0"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":true}
```

### `miner_setEtherbase`

Sets the etherbase. It changes the wallet where the validator rewards will be deposited.

#### Parameters

- Account Address

```json
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setEtherbase","params":["0x3b7252d007059ffc82d16d022da3cbf9992d2f70"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":true}
```
