Returns the value from a storage position at a given address.
Parameters
DATA, 20 Bytes - address of the storage
QUANTITY - integer of the position in the storage
QUANTITY|TAG- integer block number, or the string "latest", "earliest" or pending"
Returns
DATA - the value at this storage position.
Example
Calculating the correct position depends on the storage to retrieve. Consider the following contract deployed at 0x295a70b2de5e3953354a6a8344e616ed314d7251 by address 0x391694e7e0b0cce554cb130d723a9d27458f9298:
contract Storage {
    uint pos0;
    mapping(address => uint) pos1;
​
    function Storage() {
        pos0 = 1234;
        pos1[msg.sender] = 5678;
    }
}
Retrieving the value of pos0 is straight forward:
curl -X POST http://127.0.0.1:20339 -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' localhost:8545
Sample Response
{"jsonrpc":"2.0","id":1,"result":"0x00000000000000000000000000000000000000000000000000000000000004d2"}
Retrieving an element of the map is harder. The position of an element in the map is calculated with:
keccack(LeftPad32(key, 0), LeftPad32(map position, 0))
This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:
keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))
The geth console which comes with the web3 library can be used to make the calculation:
> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
undefined
> web3.sha3(key, {"encoding": "hex"})
"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"
Now to fetch the storage:
curl -X POST http://127.0.0.1:20339 -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' localhost:8545
Sample Response
{"jsonrpc":"2.0","id":1,"result":"0x000000000000000000000000000000000000000000000000000000000000162e"}

}
eth_call
Executes a new message call immediately without creating a transaction on the blockchain.
Parameters
Object - The transaction call object:
from: DATA，20 Bytes, 20 Bytes - (optional) The address the transaction is sent from.
to: DATA, 20 Bytes, 20 Bytes - The address the transaction is directed to.
gas: QUANTITY - (optional) Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
gasPrice：QUANTITY - (optional) Integer of the gasPrice used for each paid gas.
value：QUANTITY - (optional) Integer of the value sent with this transaction.
data: DATA - (optional) Hash of the method signature and encoded parameters.
QUANTITY|TAG - integer of a block number, or the string "earliest", "latest" or "pending".
Returns
DATA - the return value of executed contract.

}
eth_estimateGas
Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain.
Note: that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.
Parameters
See eth_call parameters. All properties are optional. If no gas limit is specified geth uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to execute the call/transaction when the amount of gas is higher than the pending block gas limit.
Returns
QUANTITY - the estimated amount of gas.
