# Standard RPC

## The default block parameter

The following methods have an extra default block parameter:

* [eth\_getBalance](#eth_getbalance)
* [eth\_getCode](https://github.com/mapprotocol/docs/blob/master/sdk/eth_getcode/README.md)
* [eth\_getTransactionCount](https://github.com/mapprotocol/docs/blob/master/sdk/eth_gettransactioncount/README.md)
* [eth\_getStorageAt](https://github.com/mapprotocol/docs/blob/master/sdk/eth_getstorageat/README.md)
* [eth\_call](https://github.com/mapprotocol/docs/blob/master/sdk/eth_call/README.md)

When requests are made that act on the state of ethereum, the last default block parameter determines the height of the block.

The following options are possible for the defaultBlock parameter:

* `HEX String` - an integer block number
* `String "earliest"` for the earliest/genesis block
* `String "latest"` - for the latest mined block
* `String "pending"` - for the pending state/transactions

}
```

### eth\_getStorageAt

Returns the value from a storage position at a given address.

#### Parameters

1. `DATA`, 20 Bytes - address of the storage.
2. `QUANTITY` - integer of the position in the storage.
3. `QUANTITY|TAG` - integer block number, or the string `"latest"`, `"earliest"` or `"pending"`, see the [default block parameter](#the-default-block-parameter)

#### 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:

```js
curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' localhost:8545

{"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:

```js
keccack(LeftPad32(key, 0), LeftPad32(map position, 0))
```

This means to retrieve the storage on pos1\["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:

```js
keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))
```

The geth console which comes with the web3 library can be used to make the calculation:

```js
> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
undefined
> web3.sha3(key, {"encoding": "hex"})
"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"
```

Now to fetch the storage:

```js
curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' localhost:8545

{"jsonrpc":"2.0","id":1,"result":"0x000000000000000000000000000000000000000000000000000000000000162e"}
```

* `value`: `QUANTITY` - (optional) Integer of the value sent with this transaction
* `nonce`: `QUANTITY` - the number of transactions made by the sender prior to this one.
* `data`: `DATA` - (optional) Hash of the method signature and encoded parameters
* `input`: `DATA` - (optional) We accept "data" and "input" for backwards-compatibility reasons. "input" is the newer name and should be preferred by clients.

1. `QUANTITY|TAG` - integer block number, or the string `"latest"`, `"earliest"` or `"pending"`, see the [default block parameter](#the-default-block-parameter)

#### Returns

`DATA` - the return value of executed contract.

#### Example

```json
// Request
curl -X POST --data '{
    "id": 1,
    "jsonrpc": "2.0",

        }
    ],
}'

{
  "id":1,
  "jsonrpc": "2.0",
  "result": "0x"
}
```

### 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](#eth_call) parameters, expect that 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 executed the call/transaction when the amount of gas is higher than the pending block gas limit.

#### Returns

`QUANTITY` - the amount of gas used.

#### Example

```js
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{"from": "0xd13fe09e7a304709b1c4ed6bd3a2d6c272357bbb","to": "0xd46e8dd67c5d32be8058bb8eb970870f07244567","gas": "0x76c0","gasPrice": "0x9184e72a000","value": "0x9184e72a","data": "0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"}, "latest"],"id":1}],"id":1}'

### 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.

Note the address to sign with must be unlocked.

#### Parameters

account, message

1. `DATA`, 20 Bytes - address.
2. `DATA`, N Bytes - message to sign.

#### Returns

`DATA`: Signature

#### Example

```js
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0xf675187ff5b76d2430b353f6736aa051253118ee", "0xdeadbeaf"],"id":1}'

// Result
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x49d04469c0671c7a8187c311cb84c2ae3d0ec4943563706699440d210a9fd15642381346c008bf034d629fb0b26aff0ede25678e3df9cafc937e1ff70b832e321c"
}
```

An example how to use solidity ecrecover to verify the signature calculated with `eth_sign` can be found [here](https://gist.github.com/bas-vk/d46d83da2b2b4721efb0907aecdb7ebd). The contract is deployed on the testnet Ropsten and Rinkeby.

### eth\_signTransaction

Signs a transaction that can be submitted to the network at a later time using with eth\_sendRawTransaction.

#### Parameters

1. `Object` - The transaction object
   * `from`: `DATA`, 20 Bytes - (optional) The address the transaction is sent from.
   * `to`: `DATA`, 20 Bytes - The address the transaction is directed to.

   * `gasPrice`: `QUANTITY` - (optional) Integer of the gasPrice used for each paid gas
   * `maxFeePerGas`: `QUANTITY` - It's just the sum of baseFeePerGas and maxPriorityFeePerGas: maxFeePerGas = baseFeePerGas + maxPriorityFeePerGas.
   * `maxPriorityFeePerGas`: `QUANTITY` - When you submit a transaction you will also provide a "tip" to the miner. This is the maxPriorityFeePerGas field. fork.
   * `value`: `QUANTITY` - (optional) Integer of the value sent with this transaction
   * `nonce`: `QUANTITY` - the number of transactions made by the sender prior to this one.

### eth\_sendRawTransaction

Creates new message call transaction or a contract creation for signed transactions.

#### Parameters

1. `DATA`, The signed transaction data.

#### Returns

`DATA`, 32 Bytes - the transaction hash, or the zero hash if the transaction is not yet available.

Use [eth\_getTransactionReceipt](#eth_gettransactionreceipt) to get the contract address, after the transaction was mined, when you created a contract.

#### Example

```js
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":[{see above}],"id":1}'

// Result
{
  "id":1,
  "jsonrpc": "2.0",
  "result": "0xe670ec64341771606e55d6b4ca35a1a6b75ee3d5145a99d05921026d1527331"
}
```

### eth\_newFilter

Creates a filter object, based on filter options, to notify when the state changes (logs). To check if the state has changed, call [eth\_getFilterChanges](#eth_getfilterchanges).

#### A note on specifying topic filters:

Topics are order-dependent. A transaction with a log with topics \[A, B] will be matched by the following topic filters:

* `[]` "anything"
* `[A]` "A in first position (and anything after)"
* `[null, B]` "anything in first position AND B in second position (and anything after)"
* `[A, B]` "A in first position AND B in second position (and anything after)"
* `[[A, B], [A, B]]` "(A OR B) in first position AND (A OR B) in second position (and anything after)"

#### Parameters

1. `Object` - The filter options:

* `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.

#### Example Parameters

```js
params: [{
  "fromBlock": "0x1",
  "toBlock": "0x2",
  "address": "0x8888f1f195afa192cfee860698584c030f4c9db1",

]
```

#### Returns

`Array` - Array of log objects, or an empty array if nothing has changed since last poll.

* For filters created with `eth_newBlockFilter` the return are block hashes (`DATA`, 32 Bytes), e.g. `["0x3454645634534..."]`.
* For filters created with `eth_newPendingTransactionFilter` the return are transaction hashes (`DATA`, 32 Bytes), e.g. `["0x6345343454645..."]`.
* For filters created with `eth_newFilter` logs are objects with following params:
  * `removed`: `TAG` - `true` when the log was removed, due to a chain reorganization. `false` if its a valid log.
  * `logIndex`: `QUANTITY` - integer of the log index position in the block. `null` when its pending log.
  * `transactionIndex`: `QUANTITY` - integer of the transactions index position log was created from. `null` when its pending log.
  * `transactionHash`: `DATA`, 32 Bytes - hash of the transactions this log was created from. `null` when its pending log.
  * `blockHash`: `DATA`, 32 Bytes - hash of the block where this log was in. `null` when its pending. `null` when its pending log.
  * `blockNumber`: `QUANTITY` - the block number where this log was in. `null` when its pending. `null` when its pending log.
  * `address`: `DATA`, 20 Bytes - address from which this log originated.
  * `data`: `DATA` - contains the non-indexed arguments of the log.
  * `topics`: `Array of DATA` - Array of 0 to 4 32 Bytes `DATA` of indexed log arguments. (In *solidity*: The first topic is the *hash* of the signature of the event (e.g. `Deposit(address,bytes32,uint256)`), except you declared the event with the `anonymous` specifier.)

### eth\_getLogs

Returns an array of all logs matching a given filter object.

#### Parameters

1. `Object` - The filter options:

* `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.
