```
### 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_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

``` -->
### 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.
