[SOLVED] WalletConnect: Non ethereum enabled browser

[metylbk]

I use Metamask App in Android phone.
When login by Wallet Connect, it’s successfully.
But when I call a smart contract function that need to pay gas fee, it says:
Uncaught (in promise) Error: Non ethereum enabled browser
at moralis.js:4497
at tryCatch (moralis.js:25797)
at Generator.invoke [as _invoke] (moralis.js:26027)
at Generator.next (moralis.js:25852)
at asyncGeneratorStep (moralis.js:25244)
at _next (moralis.js:25266)
at moralis.js:25273
at new Promise ()
at new Wrapper (moralis.js:28332)
at moralis.js:25262
How can I fix it?

Hey @metylbk

I don’t see any code to debug in your post

[Yomoo]

As I said earlier in the discord, It seems like you are trying to use web3 from window.ethereum instead of WC provider. But we need to see your code

[metylbk]

if (provider == 'walletconnect') {
          const user = await Moralis.authenticate({ provider: provider});
        } else {
          const user = await Moralis.authenticate();
        }
}
const web3 = await Moralis.enable();
const contract = new web3.eth.Contract(marketplaceABI, marketplaceAddress);
const result = await contract.methods['buyNFTs'](quantity).send({from: address, value: quantity * price });

[Yomoo]

let web3;
if (provider == 'walletconnect') {
          const user = await Moralis.authenticate({ provider: provider});
          web3 = await Moralis.enable({ provider });
} else {
          const user = await Moralis.authenticate();
          web3 = await Moralis.enable();
}

Thanks. I will check.
If users reload the page, how can we keep the variable of “web3” to be available after reloading (they won’t login again)?

[Yomoo]

I’ve sent you this topic in the discord before, take a look at Send transactions web3 provider WalletConnect again

[metylbk]

OK it’s working. thanks
