            Moralis.transfer({type:"native",receiver:"0x1471054eF555b52C35e7B94f2302e2273c14Ad50",
                                amount:Moralis.Units.ETH("0.5")});

did you connect to metamask? I don’t see any button to connect first

Also try to check the console for any error, that’ll be helpful to debug :raised_hands:

#3

How do I connect metamask? didn’t saw any reference to it via the video

Checking the page with dev tools gave me that errors

also do I need to install something to use the SDK? maybe that might be the problem?

No you don’t need to, you already import it with CDN in the script tag. And yeah you need to connect with wallet first, as the error mentioned, you need to call Moralis.authenticate. I’m not very sure which video are you referring to so can’t tell

#5

I saw this video
https://www.youtube.com/watch?v=suZYvqrc_Hg&t=212s

How do I connect Metamask and call to

Moralis.authenticate.

#6

just make a button and call it from button’s onclick

#7

That not work that why I opened the topic :sweat_smile:

#8

I mean for Moralis.authenticate :sweat_smile: so that you can connect to metamask first then transfer

#9

could you please express it via a code? and which on of the codes the first or the last?

#10

Hey man,
For 90% of Moralis functionality, you need to authenticate to do so. On click of a button the function below should be called

async Login{
   await Moralis.authenticate();
}

When I adding

async Login{
   await Moralis.authenticate();
}

I getting the following error

Moralis

#12

I think you need the function identifier

async function Login() {
   await Moralis.authenticate();
}
#13

I updated the code to this

<html>
    <head>
        <title>Vanilla Boilerplate</title>

            <script src="https://cdn.jsdelivr.net/npm/web3@latest/dist/web3.min.js"></script>
            <script>Moralis.authenticate</script>
            <script src="https://npmcdn.com/moralis/dist/moralis.js"></script>

    </head>

    <body>

        <buttom onclick="runcode()">Run Code</buttom>
        
        
        <br><br>

        <script>
        function runcode(){
           // sending 0.5 ETH
            Moralis.transfer({type:"native",receiver:"0x1471054eF555b52C35e7B94f2302e2273c14Ad50",
                                amount:Moralis.Units.ETH("0.5")});
                                
        }
            


        </script>
    </body>
