WaxJS Demo

Below is a basic example of WaxJS functionality. To use this demo, click WAX Login (if you're not automatically logged in), then click Sign Transaction.

Auto-login Feature

If your blockchain information displays below, you're automatically logged in to WaxJS, and you don't need to click WAX Login. This eliminates the need for multiple clicks and popups!

WAX Login

Use this if you're not automatically logged in. Note that if you are auto-logged in, clicking this does not open a popup and the userAccount is still returned.

<button class="text-md mt-4 border-black border-solid border-2 rounded px-4 py-2 w-40" id="login" onclick=login() >WAX Login</button>

**Sign Transaction**

Click once you're logged in.

<button class="mt-4 border-black border-solid border-2 rounded px-4 py-2 w-40" id="sign" onclick=sign() >Sign Transaction</button>

Transaction Response

Code Examples

To use these examples, download and save WaxJS from GitHub.

Simple Login

const wax = new waxjs.WaxJS({
    rpcEndpoint: 'https://wax.greymass.com'
});

autoLogin(); 

//checks if autologin is available and calls the normal login function if it is 
async function autoLogin() { 
    var isAutoLoginAvailable = await wax.isAutoLoginAvailable(); 
    if (isAutoLoginAvailable) { 
        login(); 
    } 
} 

//normal login. Triggers a popup for non-whitelisted dapps
async function login() { 
    try { 
        const userAccount = await wax.login();  
    } catch(e) { 

    } 
}
