Web3.py compatible async providers that supports multiply RPC URLs

Features

• HTTP async provider
• WebSockets async provider

Overview

HTTP w3 provider

import web3
from web3_async_multi_provider import AsyncWSMultiProvider


provider = AsyncHTTPMultiProvider(
    providers=[
        web3.AsyncHTTPProvider("https://eth.llamarpc.com"),
        web3.AsyncHTTPProvider("https://rpc.flashbots.net"),
    ]
)

WebSockets provider

import web3
from web3_async_multi_provider import AsyncWSMultiProvider


provider = AsyncWSMultiProvider(
    providers=[
        web3.providers.WebsocketProvider("wss://example.com/"),
        web3.providers.WebsocketProvider("wss://google.com/"),
    ]
)

And then add it into Web3:

w3 = web3.Web3(
    provider
    modules={"eth": [web3.eth.AsyncEth]},
    middlewares=[]
)
print(await web3.eth.chain_id)
