Install

.. code-block:: shell

   pip install xpring[py]


API
===

------
Wallet
------

Construct
---------

You can construct a ``Wallet`` from its seed.
If you do not have your own wallet yet, you can `generate one with some free
XRP on the testnet`__.

.. __: https://xrpl.org/xrp-testnet-faucet.html

.. code-block:: python

   import xpring

   seed = 'sEdSKaCy2JT7JaM7v95H9SxkhP9wS2r'
   wallet = xpring.Wallet.from_seed(seed)
   print(wallet.private_key.hex())
   # b4c4e046826bd26190d09715fc31f4e6a728204eadd112905b08b14b7f15c4f3
   print(wallet.public_key.hex())
   # ed01fa53fa5a7e77798f882ece20b1abc00bb358a9e55a202d0d0676bd0ce37a63
   print(wallet.account_id.hex())
   # d28b177e48d9a8d057e70f7e464b498367281b98
   print(wallet.address)
   # rLUEXYuLiQptky37CqLcm9USQpPiz5rkpD


Sign / Verify
-------------

A ``Wallet`` can sign and verify arbitrary bytes, but you'll generally
want to leave these low-level responsibilities to the ``Client``.

.. code-block:: python

   message = bytes.fromhex('DEADBEEF')
   signature = wallet.sign(message)
   wallet.verify(message, signature)
   # True


------
Client
------

``Client`` is the gateway to the XRP Ledger.
It is constructed with the URL of the gRPC service of a rippled_ server.
If you are running the server yourself,
you need to configure the ``[port_grpc]`` stanza in your configuration file.
In the example_ configuration file, it is commented_ out.

.. _rippled: https://github.com/ripple/rippled
.. _example: https://github.com/ripple/rippled/blob/develop/cfg/rippled-example.cfg
.. _commented: https://github.com/ripple/rippled/blob/0c6d380780ae368a2236a2e8e3e42efa4a1d2b46/cfg/rippled-example.cfg#L1181-L1183

.. code-block:: python

   # url = 'main.xrp.xpring.io:50051' # Mainnet
   url = 'test.xrp.xpring.io:50051' # Testnet
   client = xpring.Client.from_url(url)


Account
-------

.. code-block:: python

   >>> client.get_account(wallet.address)
   account_data {
     account {
       value {
         address: "rDuKotkyx18D5WqWCA4mVhRWK2YLqDFKaY"

     }
     balance {

         xrp_amount {
           drops: 999999820
         }
       }
     }

     previous_transaction_ledger_sequence {
       value: 4845872
     }
   }
   ledger_index: 4869818


Fee

.. code-block:: python

   current_ledger_size: 6
   fee {
     base_fee {
       drops: 10
     }
