[SOLVED] Executing Payable Functions from a deployed Contract Address

Moralis General
#1

Hi, So I want to execute a function from a deployed contract address. The contract was deployed to Rinkeby testnet and the address is
0x3104d924a36A55D054544A8bAbFbeb1bd2ea7E5d

For reference, I have been able to execute a read only function that returns fata from the smart Contract. For this, I used both the runContract() method and the the executeFunction() method. And each time, the function was executed properly. However, as you know, the runContract method can only run a function that does returns data from the contract. I.e a function marked as view.
Basically, I want to execute a function that takes one parameter and makes changes to the blockchain (not read values off of it).
So for my payable function, I have tried to use the executeFunction() method. Please find the code below…

//code to run an async function hooked up to a button
async function extraMint(){

const ABI = [{“inputs”:
[{“internalType”:“uint256”,“name”:“amount”,“type”:“uint256”}],“name”:"_extraMint",“outputs”:[],“stateMutability”:“payable”,“type”:“function”}
]

let options = {
contractAddress: 0x3104d924a36A55D054544A8bAbFbeb1bd2ea7E5d",
functionName: “_extraMint”.
abi: ABI,
params: {
amount: 1000 //I tried using a dynamic input from the html where I read the value of an input field and convert it to an integer, it was throwing errors, decided to use a static input to test the process.
}
}
//in some cases, I added a web3 instance here. To be honest, I don’t know what that does.

await Moralis.executeFunction(options)
}

The error generated says something about matching failure. I will attach an image of my console.
Remember, I already used Moralis to execute a function from this same deployed address and it worked smoothly. So I am sure it’s not my syntax or anything local from my PC. Thanks a lot.

here it seems like a type with a string that doesn’t have " at the start for that contract address

#3

I dont think That’s the problem. It is correctly typed on my Code editor. I just wnat to know, can the moralis execute function run payable functions? Cause it seems like it cant.

#4

it should be able to run payable functions fine
here is the documentation: https://docs.moralis.io/moralis-dapp/web3/web3#executefunction

#5

The link @cryptokid shared explains it all.
If you’re trying to pass amount to be paid, it should be

msgValue(optional): Number|String|BN|BigNumber. The value transferred for the transaction in wei.
#6

async function extraMint() {

const ABI = [{"inputs":[{"internalType":"uint256","name":"amount","type":"uint256"}],"name":"_extraMint","outputs":[],"stateMutability":"payable","type":"function"}]; // Add ABI of 0xdAC17F958D2ee523a2206206994597C13D831ec7

const extraMintInput = parseInt(document.getElementById("extraMintInput").value)

const options = {

    chain: "kovan",

    address: "0xB507BFBCF557A1EB1de005b55429621E737Bb941",

    function_name: "_extraMint",

    abi: ABI,

    params:{

        amount: "1000"

    },

    msgValue: extraMintInput

};

await Moralis.authenticate()

await Moralis.executeFunction(options);

}

This is what I have and it’s still throwing the same error.

you need to use the exact parameter names as in documentation:

const sendOptions = {
  contractAddress: "0xe...56",
  functionName: "setMessage",
  abi: ABI,
  params: {
    _newMessage: "Hello Moralis",
  },
};

for example, I see function_name in the above code instead of functionName

THANKS A LOT GUYS!!!
I just got it to work. No errors. Gracias.
