py-near

py-near is a pretty simple and fully asynchronous framework for working with NEAR blockchain.

Few steps before getting started...

• Install the latest stable version of py-near, simply running pip install py-near
• Create NEAR account and get your private key wallet

Simple money transfer

from py_near.account import Account
import asyncio
from py_near.dapps.core import NEAR

ACCOUNT_ID = "bob.near"
PRIVATE_KEY = "ed25519:..."


async def main():
   acc = Account(ACCOUNT_ID, PRIVATE_KEY)

   await acc.startup()
   print(await acc.get_balance() / NEAR)
   print(await acc.get_balance("bob.near") / NEAR)

   tr = await acc.send_money("bob.near", NEAR * 2)
   print(tr.transaction.hash)
   print(tr.logs)


asyncio.run(main())

Transfer money by phone number

from py_near.account import Account
import asyncio
from py_near.dapps.core import NEAR

ACCOUNT_ID = "bob.near"
PRIVATE_KEY = "ed25519:..."


async def main():
   acc = Account(ACCOUNT_ID, PRIVATE_KEY)

   await acc.startup()
   tr = await acc.phone.send_near_to_phone("[phone]", NEAR // 10)
   print(tr.transaction.hash)


asyncio.run(main())

Parallel requests

Only one parallel request can be made from one private key. All transaction calls execute sequentially. To make several parallel calls you need to use several private keys

acc = Account("bob.near", private_key1)

for i in range(2):
  signer = InMemorySigner.from_random(AccountId("bob.near"), KeyType.ED25519)
  await acc.add_full_access_public_key(str(signer.public_key))
  print(signer.secret_key)

Now we can call transactions in parallel

acc = Account("bob.near", [private_key1, private_key2, private_key3])
# request time = count transactions / count public keys
tasks = [
  asyncio.create_task(acc.send_money("alisa.near", 1)),
  asyncio.create_task(acc.send_money("alisa.near", 1)),
  asyncio.create_task(acc.send_money("alisa.near", 1)),
]
for t in task:
  await t
