How to Calculate the Numbers Pulled from Blockchain by Moralis?

[derekryansnzy]

Also, wouldn’t it be repeating the same codes?

Section one of the codes uses Moralis to get the specific token of a user:

async function userBudsBalance() {
    const chainOptions = {
        chain: "bsc"
    }
    const balances = await Moralis.Web3API.account.getTokenBalances(chainOptions);
    // const tokenAddress =  "0x720b40cd711df11e62dfd0c88797da100d5f09e6"; // 420 Contract Address
    const tokenAddress = "0x058cdf0ff70f19629d4f50fac03610302e746e58";
    // Buds Contract Address
    // const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
    const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
    console.log(tokenBalance.balance); // do your log here
    return tokenBalance.balance;
}

I think I got this section from a post I saw in this forum:

New SDK and token balance

Hey @bobbington Moralis.Web3 is an old syntax and will be deleted soon. We have expanded the functionality of the Moralis SDK and now you need to use Moralis.Web3API it has more functions. Take a look at: [Moralis SDK Big Update - (learn Moralis.Web3API asap)] If you want to get balance for specific token you can use .find: options = { chain: "mumbai" }; const balances = await Moralis.Web3API.account.getTokenBalances(options); const tokenAddress = "0x....9"; // You can specify …

and then I added this section:

const tokenBalance = await userBudsBalance()

tokenBalance.then((value) => {
    console.log(value);
    document.getElementById("budsBalanceNum").innerHTML = value / 10 ** 9;
}, function (error) {
    console.log(error);
});

Because @cryptokid had helped me in a different issue so I thought maybe the same code would work for two different sections. Am I making any sense? Lol I feel like I got lost in my brain

[Yomoo]

You can use await only inside async function. Try to make the code refactoring . For example:

async function userBudsBalance(){
    const chainOptions = { chain: "bsc" }
    const balances = await Moralis.Web3API.account.getTokenBalances(chainOptions);
    const tokenAddress =  "0x058cdf0ff70f19629d4f50fac03610302e746e58"; // Buds Contract Address
    const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
    return tokenBalance.balance;
}

async function updateHTML(value) {
   document.getElementById("budsBalanceNum").innerHTML = value/10**9;
}

userBudsBalance().then((balance) => {
   updateHTML(balance);
})

[derekryansnzy]

And the reason I added a second section was just to make sure the user’s tokenBalance can be displayed on the frontend, somewhere in the html

[Yomoo]

You can display it without any magic . All you need is async and await

[derekryansnzy]

so then in this case, I can just use (value) to complete the original calculation I was trying to do?

It would be…
((value) * x.budsAccumulationFromRewards) / sumOfAllHOLDRSBalances

would this be correct?

[derekryansnzy]

this looks pretty magical to someone who’s used to looking at Wordpress drag and drop lol. Coding is literally kicking my butt. I like the challenge and I love learning but wow, doing it all from scratch and knowing absolutely nothing about javascript is intense

[derekryansnzy]

I replaced the two sections of codes with yours:

async function userBudsBalance(){
    const chainOptions = { chain: "bsc" }
    const balances = await Moralis.Web3API.account.getTokenBalances(chainOptions);
    const tokenAddress =  "0x058cdf0ff70f19629d4f50fac03610302e746e58"; // Buds Contract Address
    const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
    return tokenBalance.balance;
}

async function updateHTML(value) {
   document.getElementById("budsBalanceNum").innerHTML = value/10**9;
}

userBudsBalance().then((balance) => {
   updateHTML(balance);
})

and console returned error, uncaught (in promise), tokenBalance is not defined

[Yomoo]

full code please

[Yomoo]

@derekryansnzy

tokenBalance is not defined

The error message speaks about the error itself

[derekryansnzy]

maybe I should just change my title in the forum to asking if any developers are for hire and can get this job done within a couple days lol. By the time I learn Javascript it’ll be 2025

[derekryansnzy]

you’re right, I am a big doofus. I forgot to comment out

b = tokenBalance
console.log(b)

leave it up to me to make the simplest mistakes lol I’m sorry

[Yomoo]

So does it work correctly now?

[Yomoo]

Also I suggest you to “upgrade” return for this function:

async function userBudsBalance() {
  const chainOptions = { chain: "bsc" };
  const balances = await Moralis.Web3API.account.getTokenBalances(chainOptions);
  const tokenAddress = "0x058cdf0ff70f19629d4f50fac03610302e746e58"; // Buds Contract Address
  const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
  if (tokenBalance) {
    return tokenBalance.balance;
  } else {
    return null;
  }
}

[derekryansnzy]

it called the balance of the user correctly, but I’m trying to figure out how to use that balance to calculate the amount of rewards that the user gets.

async function userBudsBalance(){
    const chainOptions = { chain: "bsc" }
    const balances = await Moralis.Web3API.account.getTokenBalances(chainOptions);
    const tokenAddress =  "0x058cdf0ff70f19629d4f50fac03610302e746e58"; // Buds Contract Address
    const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
    return tokenBalance.balance;
}

async function updateHTML(value) {
   document.getElementById("budsBalanceNum").innerHTML = value/10**9;
}

userBudsBalance().then((balance) => {
   updateHTML(balance);
})

I tried going to the browser to open up the console where the html/js file are on the VS code live server and I typed in these values:

• userBudsBalance - which returned the async function
• value - as soon I click enter, it turns into valueOf
• balance - this comes back as undefined

so now I’m not sure which of these values I can use to add to the equation to get the user’s reward amount

[derekryansnzy]

@Yomoo

async function userBudsBalance() {
  const chainOptions = { chain: "bsc" };
  const balances = await Moralis.Web3API.account.getTokenBalances(chainOptions);
  const tokenAddress = "0x058cdf0ff70f19629d4f50fac03610302e746e58"; // Buds Contract Address
  const tokenBalance = balances.find((token) => token.token_address === tokenAddress);
  if (tokenBalance) {
    return tokenBalance.balance;
  } else {
    return null;
  }
}

thanks lol I’ve been using the html to fill in “Buy Some Buds” if the function calls back they have zero balance. Your method works way better

[Yomoo]

Hey @derekryansnzy

How is it going?

[derekryansnzy]

Sorry for the late response! I fell asleep last night lol and spent most of today figuring out stuff for my BSC project. I am back to the javascript codes now. I will report back shortly with results. Really appreciate you checking in on me

[derekryansnzy]

Hey Yomoo, I am still super stuck lol. I got most of the codes to work, but really, they’re just the codes you guys have helped me out with. I did do a quick crash course on javascript, async and await and I have a much better understanding of it now. Take a look at the codes below:

    x = await Moralis.executeFunction(options)
    console.log(options);
}

x = totalRewards()
x.then(function (value) {
    document.getElementById("budsRewardPool").innerHTML = x.budsAccumulationFromRewardsFee / 10 ** 9;
    document.getElementById("rewardsCycle").innerHTML = x.theCurrentRewardsCycle;

    document.getElementById("budsDividendsPool").innerHTML = x.sumOfAllHOLDRBalances / 10 ** 9;
})

// so I thought maybe I'd do another function
// to calculate claimableRewards:
claimableRewards = async () => {
    const userEligibility = await userBudsBalance();
    console.log(userEligibility);
    // I'm not sure how to call balance from userBudsBalance.then(balance)

};

async function claimBudsRewards() {
    const web3 = await Moralis.enable();
    const Rewards = {
        contractAddress: "0x058cdF0fF70f19629D4F50faC03610302e746e58",
        functionName: "claimRewards",
        abi: window.abi
    };
    const BudsRewards = await Moralis.executeFunction(Rewards);
    console.log(Rewards);
}


document.getElementById("connectWalletBtn").onclick = login;
document.getElementById("connectWalletBtnRt").onclick = login;
document.getElementById("logoutBtn").onclick = logout;
document.getElementById("budsClaimRewards").onclick = claimBudsRewards;

I left some comments in the code, but I’ll explain here as well, just in case it’s still unclear.
I am trying to get the balance from userBudsBalance to put into another equation.
The equation would be to find out claimableRewards.
The equation is:
(balance * x.budsAccumulationFromRewardsFee) / sumOfAllHOLDRSBalances

Hope this makes sense!

Hey Yoomoo, I left an update here about 4 days ago, I was wondering if you had time to take a look at the more cleaned up codes for me? Still stuck on that one calculation bit lol
