WalletConnect Provider - eth_sendTransaction does not exist

[0xSandwich]

Hello,

I'm working on a dapp using web3modal v2 with wagmi.
Everything works fine for read functions such as getting maxSupply, mintPrice etc..
However for transaction calls it doesn't work, I get an error
eth_sendTransaction does not exist/is not available

I initialize walletconnect provider as shown in the docs on my app root file:

  // Wagmi client
  const { provider } = configureChains(chains, [
    walletConnectProvider({ projectId: config.walletConnectProjectId }),
  ]);
  const wagmiClient = createClient({
    autoConnect: true,
    connectors: modalConnectors({ appName: "web3Modal", chains }),
    provider,
  });

Then on my custom hook I create the contract instance using that same provider:
`
const provider = useProvider({chainId:5})

// Contract instance
useEffect(() => {
    if (provider && address) {
        const importPromise = import(`../artifacts/contracts/${config.contract.name}.sol/${config.contract.abiName}.json`)
        importPromise.then((contract) => {
            const contractInst = new ethers.Contract(config.contract.address, contract.abi, provider.getSigner(address))
            setContract(contractInst)
        })
    }
},[provider,address])

`

How to make transactions functions working with web3modal v2 ?
On an older project using walletconnect, I was set RPC provider and it was working. Can't find the way to do it with web3modal v2

const provider = new WalletConnectProvider({
    rpc: {
        43114: "https://api.avax.network/ext/bc/C/rpc"
    },
    chainId:43114,
});

I think issue could be caused by walletConnectProvider (which is our rpc), not supporting avax. So you basically need create new JSONRpc provider for avalanche (https://wagmi.sh/react/providers/jsonRpc) and add it to your wagmi client config.

Also, you can probably simplify your logic for contracts by also using wagmi there i.e for contract writes https://wagmi.sh/react/hooks/useContractWrite
