[MrVa55]

Is there an existing issue for this?

• I have searched the existing issues

Package Version

@wagmi/chains version "0.2.19",

Current Behavior

Trying to configure Sepolia with AlchemyProvider gives error "Error: unsupported network (argument="network", value={"name":"sepolia","chainId":11155111,"ensAddress":null}, code=INVALID_ARGUMENT, version=providers/5.7.2)". Page continuously reloads

Error doesn't happen with publicProvider or with other chains.

Expected Behavior

configuring sepolia to add to client without error

Steps To Reproduce

import { sepolia } from '@wagmi/core/chains';
import { alchemyProvider } from 'wagmi/providers/alchemy'
const { provider, webSocketProvider } = configureChains([sepolia], [ alchemyProvider({ apiKey: process.env.NEXT_PUBLIC_ALCHEMY_API_KEY }) ]);

Same with wagmi v0.12.12. Work around it by using v0.12.11.

Ethers v5 doesn't support Sepolia yet. Will need to use the jsonRpcProvider as a workaround and enter the URL manually.

Question : Any reason why this breaks in 0.12.0 and not in 0.11.7 (last 0.11.x version) ?

Because I see even 0.11.x was also using ethers v5 .

The reason why I said it breaks at 0.12.0 is because I tried incrementally upgrading wagmi version starting from 0.11.6 and it started breaking at 0.12.0.

My assumption: In 0.11.x it would go to the next provider provided in an array... in our case its publiProvider() but something was changed in 0.12.0 which is breaking it, its not fallbacking

Thanks again 🙌
