Allium

The wonderful folks at Allium have integrated with v3-polars as part of their DEX Analytics Portal grant

You'll need to configure the authentication with Allium. To do that:

If you have access to the Allium app:

1. Login to app.allium.so and create an explorer query
2. Place only {{query_text}} in the query
3. Click "save" on the top right, then "export to api"
4. Here, you will get the query id and api key

If you do not have access to the Allium app, email dexanalytics@allium.so

After you get credentials, pass them to the ALLIUM_POLARSV3_QUERY_ID and ALLIUM_POLARSV3_API_KEY environment variables

Pro tip: you can use python to set the env variables:

import os

os.environ['ALLIUM_POLARSV3_QUERY_ID'] = 'abcdefg'
os.environ['ALLIUM_POLARSV3_API_KEY'] = 'deadbeef'

# add the rest of your code here, like:
# state.v3Pool(...)

Google BigQuery

To use the GBQ database, you need to be auth'd with Uniswap Labs backend. Likely, if you don't know how to do this, then you should use another provider.

However, if you think you should be auth'd and are not, run the code below

gcloud auth login

To solve "GCP could not be imported" errors, try installing the bigquery library

pip install google-cloud-bigquery

Your provider

Create a new connector in v3/helpers/connectors using template.py. Integrate your connector into data_update.py under update_tables and make a PR!

Simple examples

Pull and then read all ETH/USDC swaps on Arbitrum

address = '0xc31e54c7a869b9fcbecc14363cf510d1c41fa443'

# if you're using allium, pass update_from='allium' to v3Pool()
arb = state.v3Pool(address, 'arbitrum', update = True) 

swaps = arb.swaps

Working off the previous example, get the price of the arbitrum pool every 15 minutes

priceArb = arb.getPriceSeries(starting, frequency = '15m', gas = True)

Calculate the output a 1 ETH swap at block 150000000

calldata = {'as_of': 150000000,
        'tokenIn': '0x82aF49447D8a07e3bd95BD0d56f35241523fBab1',
        'swapIn': 1e18}

amt, _ = arb.swapIn(calldata)
