Hi, I trying to integrate 1inch, first step is for me to ask user to approve token spend, but when i use 1inch api it gives permission to spend token to my website, not to 1inch exchange:
Message in Metamask:
Allow Http://localhost:1234 to spend your PPAY? Do you trust this site? By granting this permission, youāre allowing Http://localhost:1234 to withdraw your PPAY and automate transactions for you.
1inch dex require that they get permission right?:
I get their address with:
let url1 = "https://api.1inch.exchange/v3.0/1/approve/spender";
let url2 = "https://api.1inch.exchange/v3.0/1/tokens";
console.log(url1);
const address_spender = await fetch(url1)`enter code here`
.then( res => res.json() )
.then( data => {
console.log(data);
return data
});
where address_spender is their address
I get then api call to approve/calldata:
let url3 = "https://api.1inch.exchange/v3.0/1/approve/calldata?amount="+amount+"&tokenAddress="+selected_coin;
console.log("URL3 before tp");
console.log(url3);
const transactionParameters = await fetch(url3)
.then( res => res.json() )
.then( data1 => {
console.log("url3 ");
console.log(data1);
const transactionParameters = {
to: data1['to'], // Required except during contract publications.
from: user_address[0], // must match user's active address.
value: "0",
data: data1['data']
};
return transactionParameters
});
try {
const txHash = await ethereum.request({
method: 'eth_sendTransaction',
params: [transactionParameters],
});
let data = txHash.data;
} catch (error) {
if (error.code === 4001) {
alert("User denied transaction signature.")
} else {
alert(error)
}
}
and send tx via metamask, but only my website get permission. So do you have any suggestions?
Thanks!
