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.
import xpring
seed = 'sEdSKaCy2JT7JaM7v95H9SxkhP9wS2r'
wallet = xpring.Wallet.from_seed(seed)
print(wallet.public_key.hex())
# ed01fa53fa5a7e77798f882ece20b1abc00bb358a9e55a202d0d0676bd0ce37a63
print(wallet.private_key.hex())

A Wallet can sign and verify arbitrary bytes, but you’ll generally want to leave these low-level responsibilities to the Client.
message = bytes.fromhex('DEADBEEF')
signature = wallet.sign(message)
wallet.verify(message, signature)
# TrueClient
Client is the gateway into the XRP Ledger.
Construct
Client is constructed with the URL of a Xpring server. You may use the one operated by Ripple for the XRP testnet.
url = 'grpc.xpring.tech:80'
client = xpring.Client.from_url(url)Balance
address = 'r3v29rxf54cave7ooQE6eE7G5VFXofKZT7'
client.get_balance(address)
