[SOLVED] Amount Trouble ERC20 tranferring

Moralis General
#1

Hi!
When I trying to transfer erc20 token, amount of tokens become sooo big

my code

async function tokenTransfer() {
    var value = document.getElementById("value").value;
    const contract = "0x04c747b40be4d535fc83d09939fb0f626f32800b";
    const myadress = "0x97B6E7647fba574Ca1E9B46eDe48DB7188160cE2";
    await Moralis.authenticate({ signingMessage: "Test Authenticate" });
    const web3 = await Moralis.enableWeb3();
    

    const options = {type: "erc20", 
                 amount: Moralis.Units.Token(value, "18").toString(), 
                 receiver: myadress,
                 contractAddress: contract}
let result = await Moralis.Web3.transfer(options)
}

12 1200000

What was the value read from that html element?

#4

I entered the value 12 in the input field
it read the value as 12

<input type="number" placeholder="0" id="value"></input>

12

#5

From that print screen it looks like it tries to make a native transfer and not an erc20 transfer

#6

other options for ERC20 trasfer writed on my script

async function tokenTransfer() {
    var value = document.getElementById("value").value;
    const contract = "0x04c747b40be4d535fc83d09939fb0f626f32800b";
    const myadress = "0x97B6E7647fba574Ca1E9B46eDe48DB7188160cE2";
    await Moralis.authenticate({ signingMessage: "Test Authenticate" });
    const web3 = await Moralis.enableWeb3();
    

    const options = {type: "erc20", 
                 amount: Moralis.Units.Token(value, "18").toString(), 
                 receiver: myadress,
                 contractAddress: contract}
let result = await Moralis.Web3.transfer(options)
}

from html-input i get only token amount

If you send directly without converting it to wei I guess that you don’t get the right pop up in metamask either

#8

what do i need to do to fix this?

#9

I don’t know know now, you have latest version of Moralis SDK?
I’m not at computer now to test

#10

This should be without web3, it should be Moralis.transfer directly

#11

i replaced this with Moralis.transfer(options) but the amount is still very large
i have this version of Moralis and Web 3

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

That seems ok for the sdk version

This is the example from documentation, seems similar to what you have


// sending 0.5 tokens with 18 decimals
const options = {type: "erc20", 
                 amount: Moralis.Units.Token("0.5", "18"), 
                 receiver: "0x..",
                 contractAddress: "0x.."}
let result = await Moralis.transfer(options)
#13

Now i have this code, still large

const options = {type: "erc20", 
                 amount: Moralis.Units.Token(value, "18"), 
                 receiver: myadress,
                 contractAddress: contract}
let result = await Moralis.transfer(options)
}

I don’t know now what is the problem, I can test in 1-2 hours

#15

If you change in native instead of erc20 you get same pop up in MetaMask?

#16

I get BNB send window with correct amount

12bnb

#17

Ok, so there isn’t the problem with native. What token are you trying to send there, how many decimals has that token? Not all tokens have 18 decimals

#18

ITAM token. this token based on BEP20 and have 18 decimals

Bscscan info:

18

#19

How does MetaMask know the value of that token?

#20

i don’t know. I just trying to tranfer it like in moralis documentation

#21

Did you add that token to MetaMask?
