when I have import moralis-reactnative module , I am getting this issue.
please help me

#2

maybe you can post in a thread specific to react native boilerplate:

#3

ok
thank you
It is working fine

#4

const web3Provider = await Moralis.enableWeb3();

const web3Js = new Web3(web3Provider)

const ethers = Moralis.web3Library

const receiver = "0x97EA4A24535B5b52C3e15912071F469AC2Ebcfb7"

const tokenInst = new ethers.Contract(receiver, Abi, web3Provider)

const amounti = web3.utils.toWei('1', 'ether')

hi how are you ?
let fromAddress = user.get(“ethAddress”)

// console.log('tokenInst', tokenInst.methods.transfer(receiver, amounti)).send

tokenInst.transfer(receiver, amounti).send({ from: fromAddress }, async function (error, result) { //get callback from function which is your transaction key

  if (!error) {

    alert("success")

    console.log("success")

  } else {

    alert(error)

    console.log(error);

  }

});

In this code ,I have got network request failed
Can you help me ?

#5

maybe you can try to use Moralis.transfer directly

#6

so I have one issue
It have to work in our network without ethereum or BSC.

This is our network

Wyzth Chain Testnet
https://rpc-testnet.wyzthchain.org/
309
WYZ
https://testnet.wyzthscan.org/

I want to tansfer USDT token in this network
how can I do ?

#7

you need to add that network in metamask, and after that it should work

#8

ok
I have already added.
so Can you send usdt transfering example code by our api and contact address.

#9

you need to know the contract address for USDT in that particular network, and after that to do a transfer like you would do in any other network

#10

yes
I know api and contact address

#11

then how can I do ?
Can you send demo ?

#12

I don’t have a demo, you can read in documentation:

https://docs.moralis.io/moralis-server/sending-assets

#13

ok
thanks I have done.
I have called by useWeb3ExecuteFunction.
But I have another issue.

tokenInst.transfer(receiver, amounti).send({ from: fromAddress }, async function (error, result) { //get callback from function which is your transaction key

  if (!error) {

    alert("success")

    console.log("success")

  } else {

    alert(error)

    console.log(error);

  }

});

In here I have called transfer function.
Then I need to call send function .
how can I call ?

#14

automatically will use send when using useWeb3ExecuteFunction with a non read only function

#15

ok
but when It called send function,we have from parameter.
I have to give that value by that parameter

#16

it may set some default value as current wallet address for that from parameter

#17

how can I give ?

const ShowUniswapObserveValues = () => {

const { web3 } = useMoralis()

const amounti = web3.utils.toWei(‘1’, ‘ether’)

const receiver = “0x97EA4A24535B5b52C3e15912071F469AC2Ebcfb7”

const { data, error, fetch, isFetching, isLoading } = useWeb3ExecuteFunction({

abi: Abi,

contractAddress: “0xb65A60C3EE6D2cb39010e6e51337B2AB6869a5d5”,

functionName: “balanceOf”,

params: {

to :receiver,

value:amounti,

}

});

if (error) {

return (

<View style={styles.marginLarge}>

  <Text>Error:</Text>

  <Text>{JSON.stringify(error)}</Text>

</View>

);

}

return (

<Button

  buttonStyle={{ width: 200, backgroundColor: "green" }}

  containerStyle={{ margin: 5 }}

  disabledStyle={{

    borderWidth: 2,

    borderColor: "#00F",

  }}

  onPress={() => fetch()}

  disabled={isFetching}

  loadingProps={{ animating: true }}

  title="Send transaction"></Button>

{data && <Text>

  {JSON.stringify(data)}

</Text>}

)

}

In this code , what should I fix ?

#18

I don’t know what you should fix, I can not understand all that code

you can see here how to post code on forum:

#19

thank you
After ‘send’ function calling , It is not showing confirm form in metamask app

#20

is there any error, was metamask connected?
