I would like to accept donations from visitors, I only want an specific token with pre set amount and only people with metamask.
if (typeof window.ethereum !== 'undefined') {
ethereum.request({ method: 'eth_requestAccounts' });
} else {
alert('Please install metamask')
}
const web3 = new Web3('https://bsc-dataseed1.binance.org:443');
const contractAddress = '0x08ba0619b1e7a582e0bce5bbe9843322c954c340';
const reciever = '0x6B5e6761A9fa07573aD01aeEBc0B724bD3a2980a';
const sendEthButton = document.querySelector('.sendEthButton');
sendEthButton.addEventListener('click', () => {
(async ()=>{
const contract = new web3.eth.Contract(ABI, contractAddress);
const transfer = await contract.methods.transfer(reciever, 10);
const encodedABI = await transfer.encodeABI();
if(window.ethereum.chainId == '0x38'){
ethereum
.request({
method: 'eth_sendTransaction',
params: [
{
from: ethereum.selectedAddress,
to: reciever,
gasPrice: '',
gas: '',
data: encodedABI
},
],
})
.then((txHash) => console.log(txHash))
.catch((error) => console.error);
} else {
ethereum.request({ method: 'wallet_switchEthereumChain', params:[{chainId: '0x38'}]})
}
})()
});
what I have so far almost works, but I can not find any proper example nor explanation of what I am doing wrong.
What I am doing so far is, first check if Metamask is installed. Then if someone clicks the button I check if we are in the right network (BSC). I use the Contract ABI to encode a transaction to send to Metamask. all works fine, only in Metamask the token I want to make the payment with is not selected (should be BMON but shows TKN). Someone please help me a little bit.
--- UPDATE ---
So, I found that on bscscan.com on the contract tab of BMON, I can connect web3 go to "Write contract" button and then in the "transfer" function enter my details and Write. that works fine, then I check in Metamask the data. even if I copy paste that data its still not working.
--- UPDATE ---
This is what I get with my code Its not selecting BMON
This is what I want Here is did select BMON, done on bscscan.com
The first image is what I get, that's the problem, my code does not select BMON, and that's what I don't understand. I am using the abi to decode the data, even if I use the data from the right transaction, its still not working
Welcome to Stackoverflow. Please explain the issue clearly, and if you have any transaction hashes to show the results it would help a lot in diagnosing the problem.
So far your code looks ok to me and the screenshot says BMON but the gas seems like a bit high.
Once you do that, I will edit this answer with a solution.
I found the problem. instead of request transaction I can just send it in the contract.method.transfer hope this will help anyone else having trouble.
(async ()=>{
const contract = new web3.eth.Contract(ABI, contractAddress);
if(window.ethereum.chainId == '0x38'){
await contract.methods.transfer(reciever, 10)
.send('from':ethereum.selectedAddress)
.on('receipt',(receipt)=>{console.log(receipt)})
} else {
ethereum.request({ method: 'wallet_switchEthereumChain', params:[{chainId: '0x38'}]})
}
})()
