Usage examples

Simple high-level interface (through HTTP):

import asyncio
import aioethereum

loop = asyncio.get_event_loop()

async def go():
    client = await aioethereum.create_ethereum_client(
        'http://localhost:8545', loop=loop)
    val = await client.web3_clientVersion()
    print(val)

loop.run_until_complete(go())
# will print like 'Geth/v1.7.0-stable-6c6c7b2a/darwin-amd64/go1.9'

or via IPC

import asyncio
import aioethereum

loop = asyncio.get_event_loop()

async def go():
    client = await aioethereum.create_ethereum_client(
        'ipc://<path_to_unix_socket>', loop=loop)
    val = await client.web3_clientVersion()
    print(val)

loop.run_until_complete(go())
# will print like 'Geth/v1.7.0-stable-6c6c7b2a/darwin-amd64/go1.9'

Requirements

• Python 3.3+
• asyncio or Python 3.4+
• ujson
• aiohttp

Note

ujson is preferred requirement. Pure C JSON encoder and decoder is implemented as well and can be used automatically when installed.
