Data tools for Web3

web3-data-tools

Install

pip install web3_data_tools

How to use

from datetime import datetime, timezone
from web3_data_tools.core import *
from web3_data_tools.web3 import *

Set your web3 object with multiple rpcs.

w3 = MultiRPCWeb3.from_rpcs('http://bad_rpc', 'http://localhost:8545')

Before fetching data sort the RPCs so w3 calls the one that is most up to date

w3.sort_providers(tolerance=0)

RPC connection http://bad_rpc failed with: HTTPConnectionPool(host='bad_rpc', port=80): Max retries exceeded with url: / (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object>: Failed to resolve 'bad_rpc' ([Errno 8] nodename nor servname provided, or not known)"))

['http://localhost:8545', 'http://bad_rpc']

Access Web3.Eth methods

w3.eth.get_block_number()

19990236

Use web3 list like interfacte

the len function will give you the latest block number

len(w3)

19990236

the __getitem__ method maps block_number->block_timestamp

w3[len(w3)]

1717163651

Using the list-like interace you can implement any algorithm that uses lists. For example, you can use the interpolation_search method to find a block number at a specific timestamp

w3.find_block_at_timestamp(datetime(2022, 10, 1, tzinfo=timezone.utc).timestamp(), low=FIRST_POS_BLOCK, how='after')

Asycn Mode and Batched Calls

aw3 = MultiRPCWeb3.async_from_rpcs('http://bad_provider:1234', 'http://localhost:8545')
await aw3.asort_providers(tolerance=0)
await aw3.afind_block_at_timestamp(datetime(2022, 10, 1, tzinfo=timezone.utc).timestamp(), low=FIRST_POS_BLOCK, how='after')

RPC connection http://bad_provider:1234 failed with: Cannot connect to host bad_provider:1234 ssl:default [nodename nor servname provided, or not known]

15649595

block_numbers = range(FIRST_POS_BLOCK, FIRST_POS_BLOCK + 72)
blocks = await aw3.abatch_method('get_block', block_numbers, method_args=(), method_kwargs={'full_transactions': False}, batch_size=72)

len(blocks)

72

blocks[0]
