# aioeos
[](http://aioeos.readthedocs.io/en/latest/?badge=latest) [](https://codecov.io/gh/ulamlabs/aioeos)  
Async Python library for interacting with EOS.io blockchain.
## Features
1. Async JSON-RPC client.
2. Signing and verifying transactions using private and public keys.
3. Serializer for basic EOS.io blockchain ABI types.
4. Helpers which provide an easy way to generate common actions, such as token
transfer.
## Installation
Library is available on PyPi, you can simply install it using `pip`.
```
$ pip install aioeos
```
## Usage
### Importing a private key
```
from aioeos import EosAccount
account = EosAccount(private_key='your key')
```
### Transferring funds
```
from aioeos import EosJsonRpc, EosTransaction
from aioeos.contracts import eosio_token
rpc = EosJsonRpc(url='http://127.0.0.1:8888')
block = await rpc.get_head_block()
transaction = EosTransaction(
ref_block_num=block['block_num'] & 65535,
ref_block_prefix=block['ref_block_prefix'],
actions=[
eosio_token.transfer(
from_addr=account.name,
to_addr='mysecondacc1',
quantity='1.0000 EOS',
authorization=[account.authorization('active')]
)
]
)
await rpc.sign_and_push_transaction(transaction, keys=[account.key])
```
### Creating a new account
```
from aioeos import EosJsonRpc, EosTransaction, EosAuthority
from aioeos.contracts import eosio
main_account = EosAccount(name='mainaccount1', private_key='private key')
new_account = EosAccount(name='mysecondacc1')
owner = EosAuthority(
threshold=1,
keys=[new_account.key.to_key_weight(1)]
)
rpc = EosJsonRpc(url='http://127.0.0.1:8888')
block = await rpc.get_head_block()
await rpc.sign_and_push_transaction(
EosTransaction(
ref_block_num=block['block_num'] & 65535,
ref_block_prefix=block['ref_block_prefix'],
actions=[
eosio.newaccount(
main_account.name,
new_account.name,
owner=owner,
authorization=[main_account.authorization('active')]
),
eosio.buyrambytes(
main_account.name,
new_account.name,
2048,
authorization=[main_account.authorization('active')]
)
],
),
keys=[main_account.key]
)
```
## Documentation
Docs and usage examples are available [here](https://aioeos.readthedocs.io/en/latest).
## Unit testing
