How to use with the Base chain?

[troublesprouter]

I tried adding the data to constants.py in a fork but still get "execution reverted"

Any ideas on how to make it work?

here's my modified constants.py:

If anyone could please add compatibility to base it would be amazing. I've tried but to no avail.

Hi, do you have the solution already?

[jhcdx9999]

I have the same issue of "execution reverted", and the error starts from "self.router.functions". However, I know that Uniswap Base chain uses Universal Router (0x3fc91a3afd70395cd496c647d5a6cc9d4b2b7fad). This router has different functions. Therefore, I think some new logic needs to be added into uniswap.py file.

router: 0x4752ba5dbc23f44d87826276bf6fd6b1c372ad24
factory: 0x8909Dc15e40173Ff4699343b6eB8132c65e18eC6

router: 0x4752ba5dbc23f44d87826276bf6fd6b1c372ad24 factory: 0x8909Dc15e40173Ff4699343b6eB8132c65e18eC6

Thanks! It works on swapping tokens on Uniswap V2, but do you also know the ROUTER of Uniswap V3 compiled with uniswap.py?

I have set up all the contracts as below, but still getting 'execution reverted' error.

Interesting. I am trying to do something similar with the official Typescript SDK, but I am running into a similar error.
In my case I am testing trying to get a quote. Does anyone know if the Universal Router is involved in quoting? At a glance, it does not appear to be involved.

Uniswap/examples#79

[jfbloom22]

Not sure if it will help, but I resolved the issue I was running into after I learned the contract I was targeting was a different version.

I discovered it my downloading the ABI directly from Etherscan and running a diff.

Here is what I changed just in case it helps you:
Uniswap/examples#79

FYI I found some updated examples from Uniswap here: https://discord.com/channels/597638925346930701/607978109089611786/948847107744333844

Hope it helps!
