Python SDK for Terra

Project description

 

Jigu (지구)

The Python SDK for Terra.

Installation

Jigu requires Python 3.7+. Install the latest version of Jigu with pip on PyPI:

$ pip install -U jigu

Pretty Printing

Many objects in Jigu are pretty-printable by their ._pp property.

        
Python 3.7.6 (default, Dec 30 2019, 19:38:26) >>> from jigu import Terra >>> terra = Terra("columbus-3", "https://lcd.terra.dev/") >>> terra.market.params()._pp ╒═════════════════════════╤═════════════════╕ │ pool_recovery_period │ 14400 │ ├─────────────────────────┼─────────────────┤ │ base_pool │ 250000000000 │ ├─────────────────────────┼─────────────────┤ │ min_spread │ 0.02 │ ├─────────────────────────┼─────────────────┤ │ tobin_tax │ 0.0025 │ ├─────────────────────────┼─────────────────┤ │ illiquid_tobin_tax_list │ ╒══════╤══════╕ │ │ │ │ umnt │ 0.02 │ │ │ │ ╘══════╧══════╛ │ ╘═════════════════════════╧═════════════════╛

My First Transaction

Connect to Soju testnet

Once you've installed Jigu, fire up an interactive Python shell and connect to the Soju testnet using the official Soju node provided by Terraform Labs.

from jigu import Terra

soju = Terra("soju-0013", "https://soju-lcd.terra.dev")
assert soju.is_connected()

Create an account

Before we can make any transactions, we have to have an account. Enter in the above to create an account and print its account address.

from jigu.key.mnemonic import MnemonicKey

wallet = soju.wallet(MnemonicKey.generate())
wallet.address
# terra17w4ppj92dwdf93jjtply08nav2ldzw3z2l3wzl

Top off with testnet funds

Great, now that we have an address, let's get some testnet funds. Head over to the Soju Faucet and top off some Luna.

After that's done, you should have 10,000 LUNA in your account. To confirm this, you can enter the following:

wallet.balance("uluna")
# Coin('uluna', 10000000000)

Create a transaction

Let's send 23 Testnet Luna to your friend at the following address:

terra1wg2mlrxdmnnkkykgqg4znky86nyrtc45q336yv

We'll need to create a transaction containing a MsgSend alongside a short memo (note) "Hello Jigu!" -- our version of Hello World.

from jigu.core import Coins, StdFee
from jigu.core.msg import MsgSend

send = MsgSend(
    from_address=wallet.address,
    to_address="terra1wg2mlrxdmnnkkykgqg4znky86nyrtc45q336yv",
    amount=Coins(uluna=23_000_000)
)

fee = StdFee.make(50000, uluna=1000) # include a small fee..

tx = wallet.create_and_sign_tx(send, memo="Hello Jigu!", fee=fee)
res = wallet.broadcast(tx)

See it on the blockchain

It should take around 6 seconds to finalize. If everything went well, you should get a result object with the height and TX hash after about 6 seconds.

print(f"TX Hash: {res.txhash}")
# TX Hash: 82D5440A4C4CAB5B74EE3C98CE7F755372CD92E945425A572654179A4A0EE678

Copy the TX hash and enter it on Finder, selecting the chain soju-0013.
