  - maxPriorityFeePerGas: optional, maximum fee, in wei, the sender is willing to pay per gas above the base fee. See EIP-1559 transactions. If used, must specify maxFeePerGas.
  - maxFeePerGas: optional, maximum total fee (base fee + priority fee), in wei, the sender is willing to pay per gas. See EIP-1559 transactions. If used, must specify maxPriorityFeePerGas.
  - value: optional, hexadecimal of the value transferred, in wei.
  - data: optional, hash of the method signature and encoded parameters. See Ethereum contract ABI specification.
- blockNrOrHash: BlockNumberOrHash, optional, a string representing a block number, block hash, or one of the string tags
  - latest
  - earliest

  - finalized.

Returns:

result: object accessListResult:

## Method eth_sign

The `sign` method calculates an Ethereum specific signature with: `sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message)))`.

Returns:

result: array of byte

```shell
curl -s -X POST -H "Content-Type: application/json" ${RPC} -d '{

## Method eth_newPendingTransactionFilter

The `newPendingTransactionFilter` method creates a filter in the node, to notify when new pending transactions arrive. To check if the state has changed, call `eth_getFilterChanges`.

Parameters:

None

Returns:

result: string

Example:

```shell
curl -s -X POST -H "Content-Type: application/json" ${RPC} -d '{
  "jsonrpc": "2.0",
  "id": 1001,
  "method": "eth_newPendingTransactionFilter"
}' | jq
```

  "jsonrpc": "2.0",
  "id": 1001,
  "result": "0x6c6a174e72b1d72d44f3b212269bfcf8"
}
```

### Method eth_uninstallFilter

The `uninstallFilter` method uninstalls a filter with given ID. This method should always be called when watching is no longer needed. Additionally, filters time out when they aren't requested with `eth_getFilterChanges` for a period of time.

Parameters:

- id: string, required, a string denoting the ID of the filter to be uninstalled.

Returns:

result: bool, true if the filter was successfully uninstalled, otherwise false

```shell
curl -s -X POST -H "Content-Type: application/json" ${RPC} -d '{
  "jsonrpc": "2.0",
  "id": 1001,
  "method": "eth_uninstallFilter",
  "params": [

  ]
}' | jq
