on āSign in with Metamaskā. I think itās because Iām already signed in. But for signed in users, theyāre supposed to see the game.
If it helps at all, the Youtube video you showed me, at the timestamp 11:59 is where Iām stuck.
In case you need the video link again:
You can open the console to see if it says anything there.
Thanks. It turns out that the console.log(user) was supposed to be console.log(currentUser). I didnāt make any changes to it because I thought whatever I copied from the Github should be the right code to use. Next time I know! Thank you again.
yep, now I also found that this was the problem 
Okay so I followed through all the videos, now I am back to building the frontend dapp to call a function of my contract. I saw in the Moralis docs and also another post in this forum that @Yoomoo recommended to use the Moralis.execute code.
Hereās the code I found in the docs:
const ABI = [
{
constant: true,
inputs: [
{
internalType: "address",
name: "owner",
type: "address"
},
{
internalType: "address",
name: "spender",
type: "address"
}
],
name: "allowance",
outputs: [
{
internalType: "uint256",
name: "",
type: "uint256"
}
],
payable: false,
stateMutability: "view",
type: "function"
}
];
const options = {
contractAddress: "0xe...56",
functionName: "allowance",
abi: ABI,
params: {
owner: "0x2...45",
spender: "0x3...49"
},
};
const allowance = await Moralis.executeFunction(options);
Since I have the abi of the contract code in another js file from when I followed the Serverless dapp videos, I modified the codes a little. Please take a look:
const claimRewards = {
contractAddress: "0xb48D1488266F636dB97597875dE305Bb981EC5a5",
functionName: "claimRewards",
abi: window.abi,
params: {
// I don't know what to set for params because the function is claimRewards.
// It simply calls the contract to send the rewards to the connected wallet.
}
};
const allowance = await Moralis.executeFunction(claimRewards);
Iād appreciate any help I can get with this!
You could try to use it without params.
An example without params.
Thanks for the super fast response!
I got this error in the console:

I am using a Moralis server on Ganache, deployed smart contract to Ganache. I changed my code to this:
async function claimBudsRewards(){
const web3 = await Moralis.enable();
const contract = new web3.eth.Contract(window.abi, "0xac5FB3Ac3De96470C612CeDBcE80EB42b1f5C0e7");
const Rewards = {
contractAddress: "0xac5FB3Ac3De96470C612CeDBcE80EB42b1f5C0e7",
functionName: "claimRewards",
abi: window.abi,
};
const BudsRewards = await Moralis.executeFunction(claimBudsRewards);
}
Thank you again!
You may want to use:
async function claimBudsRewards(){
const Rewards = {
contractAddress: "0xac5FB3Ac3De96470C612CeDBcE80EB42b1f5C0e7",
functionName: "claimRewards",
abi: window.abi,
};
const BudsRewards = await Moralis.executeFunction(Rewards);
}
I got a āmissing web3 instanceā
so I added the line back in:
async function claimBudsRewards(){
const web3 = await Moralis.enable(); // added this line back in
const Rewards = {
contractAddress: "0xac5FB3Ac3De96470C612CeDBcE80EB42b1f5C0e7",
functionName: "claimRewards",
abi: window.abi,
};
const BudsRewards = await Moralis.executeFunction(Rewards);
}
It worked! Thank you for guiding me through this. Iām new to all this and coding scared the crap out of me. But thanks to you guys, Iām actually enjoying this quite a bit now. Canāt wait to come back and show yāall the results!
Hey I m also going through same problem I call the totalSupply function from my bsc contract for that I have to apply execute or run contract?
And I want to show the total supply in my console
both Moralis.executeFunction and runContractFunction should work
an example:
ERC20_ABI = [
{
constant: true,
inputs: [],
name: "totalSupply",
outputs: [{ name: "", type: "uint256" }],
payable: false,
stateMutability: "view",
type: "function",
},
];
x = await Moralis.Web3API.native.runContractFunction({
chain: "avalanche",
address: "0xb31f66aa3c1e785363f0875a1b74e27b85fd66c7",
function_name: "totalSupply",
abi: ERC20_ABI,
})
thats my main js file , i want to read totalsupply from my contract which is on mainnet bscā¦
and print it on my console ,
login = async () => {
Moralis.Web3.authenticate().then(function (user) {
console.log(user.get('ethAddress'))
})
}
async function cptsupply() {
const web3 = await moralis.enable();
const options = {
chain: "bsc",
address: "0x28e4f32fa7e842ad0a6e530bb6b4ec03b36d5078",
function_name: "totalSupply",
abi: window.abi,
};
const allowance = await Moralis.runContractFunction(options);
console.log(allowance);
}you can look at the above example that I gave, where you replace chain and address and it should work fine
its right , bcz i dont change the abi too
ogin = 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);
}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 ā¦ 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 doesnāt 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 ā¦ only i get in console is my connected address ,not get totalsupply ā¦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: ābscā,
address: ā0x28e4f32fa7e842ad0a6e530bb6b4ec03b36d5078ā,
function_name: ātotalSupplyā,
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?
