does it work now for you?
it did not show the total supply in console
and one more question i did not use web3 api for showing data … soo why i used
await Moralis.Web3API.native.runContractFunctionif you run the code from here on console: [SOLVED] Calling functions on BSC deployed contract
it should work
web3 instance is needed for Moralis.executeFunction
Moralis.Web3API.native.runContractFunction doesn’t use a web3 instance (like a connection to MetaMask), but both will require to have your server url and app id configured
did you see any errors on console, did that function get executed?
i did not get any error … only i get in console is my connected address ,not get totalsupply …this is my code
<script>
// connect to Moralis server
Moralis.initialize("pfaPMZpSl0COD4qDiZ6ytcu2ePIMaPWI2pSrhTZm");
Moralis.serverURL = "https://4l81fhpvqkit.usemoralis.com:2053/server";
// Login with metamask and get the ethAddress
login = async () => {
Moralis.Web3.authenticate().then(function (user) {
console.log(user.get('ethAddress'))
})
}
async function cptsupply() {
const web3 = await moralis.enable();
ERC20_ABI = [
{
constant: true,
inputs: [],
name: "totalSupply",
outputs: [{ name: "", type: "uint256" }],
payable: false,
stateMutability: "view",
type: "function",
},
];
x = await Moralis.Web3API.native.runContractFunction({
chain: “bsc”,
address: “0x28e4f32fa7e842ad0a6e530bb6b4ec03b36d5078”,
function_name: “totalSupply”,
abi: ERC20_ABI,
})
console.log(x);
}
I executed now this code in console and it works fine:
ERC20_ABI = [
{
constant: true,
inputs: [],
name: "totalSupply",
outputs: [{ name: "", type: "uint256" }],
payable: false,
stateMutability: "view",
type: "function",
},
];
x = await Moralis.Web3API.native.runContractFunction({
chain: "bsc",
address: "0x28e4f32fa7e842ad0a6e530bb6b4ec03b36d5078",
function_name: "totalSupply",
abi: ERC20_ABI,
})
console.log(x);
=> 10000000000000000000000
where do you call that cptsupply function?

await is only valid with async function x = await Moralis.Web3API.native.runContractFunction
for this line i have to make a function cptsupply , can u give me your whole code which shows totalsupply in console …
this is my code
<script>
// connect to Moralis server
Moralis.initialize("pfaPMZpSl0COD4qDiZ6ytcu2ePIMaPWI2pSrhTZm");
Moralis.serverURL = "https://4l81fhpvqkit.usemoralis.com:2053/server";
// Login with metamask and get the ethAddress
login = async () => {
Moralis.Web3.authenticate().then(function (user) {
console.log(user.get('ethAddress'))
})
}
async function cptsupply() {
const web3 = await moralis.enable();
ERC20_ABI = [
{
constant: true,
inputs: [],
name: “totalSupply”,
outputs: [{ name: “”, type: “uint256” }],
payable: false,
stateMutability: “view”,
type: “function”,
},
];
x= await Moralis.Web3API.native.runContractFunction({
chain: “bsc”,
address: “0x28e4f32fa7e842ad0a6e530bb6b4ec03b36d5078”,
function_name: “totalSupply”,
abi: ERC20_ABI,
})
cptsupply();
console.log(x);
}
try to paste the code from here in your browser console: [SOLVED] Calling functions on BSC deployed contract
it looks like you are trying to call same function recursively there, that is what you want to do?
so for printing the totalsupply in my console
i do console.log(x);
but it is not giving total supply …
and uhh say dat i did not call the function cptsupply so i call it …
and if i dont make async cptsupply function then
x= await Moralis.Web3API.native.runContractFunction
shows error in console without async await did not work …
and i also run the code u give in browsers console
you have to use Moralis.start now, you have an example here: https://github.com/MoralisWeb3/demo-apps/tree/main/moralis-vanilla-boilerplate
can u give pics of ur console
this dont works even my metamask sign in not happening,
i use this before
can u edit my given code and tell me wheres the error
and very thanks sir for helping
in this code what i have to do to print totalsuplly in console…
you copy the html and js files from that github link, and then it should work
after that you can open the browser console and paste the above code
html file
Vanilla Boilerplate Moralis Metamask Login Logout </htmljs file
async function login() {
let user = Moralis.User.current();
if (!user) {
user = await Moralis.authenticate({ signingMessage: "Hello World!" })
.then(function (user) {
console.log("logged in user:", user);
console.log(user.get("ethAddress"));
})
.catch(function (error) {
console(error);
});
try {
user = await Moralis.authenticate({ signingMessage: "Hello World!" })
console.log(user)
console.log(user.get('ethAddress'))
} catch(error) {
console.log(error)
}
}
}
i open signup into the metamask there on bscmainnet , my address shows in console , then i copy ur code and paste there , as u say but i get error , and the code which is on github is not working it dont oipen the metamask… my code
// connect to Moralis server
Moralis.initialize("pfaPMZpSl0COD4qDiZ6ytcu2ePIMaPWI2pSrhTZm");
Moralis.serverURL = "https://4l81fhpvqkit.usemoralis.com:2053/server";
// Login with metamask and get the ethAddress
login = async () => {
Moralis.Web3.authenticate().then(function (user) {
console.log(user.get('ethAddress'))
})
}
Did you start a http server?
moralis server is https
and the local host is http from
vscode live server
