Error: transaction failed on PancakeSwap trading bot
Genray100 opened this issue · comments
So I have been trying to adjust the bot to buy a specific token using swapExactETHForTokens instead of swapExactTokensForTokens since I heard that there is no need to approve when using the former.
const addresses = {
WBNB: '0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c',
factory: '0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73',
router: '0x10ed43c718714eb63d5aa57b78b54704e256024e',
recipient: 'my_wallet_address'
}
const mnemonic = 'seed phrase left our for obvious reasons';
const provider = new ethers.providers.WebSocketProvider('wss://bsc-ws-node.nariox.org:443');
const wallet = ethers.Wallet.fromMnemonic(mnemonic);
const account = wallet.connect(provider);
const router = new ethers.Contract(
addresses.router,
[
'function swapExactETHForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline) external returns (uint[] memory amounts)'
],
account
);
const init = async () => {
const options = {gasPrice: 5000000000, gasLimit: 400000 };
const amountIn = ethers.utils.parseUnits('0.1', 'ether');
const amountOutMin = 1
const tx = await router.swapExactETHForTokens(
amountIn,
amountOutMin,
[addresses.WBNB, '0xb3225ac90b741f762beca76dea1ead278ef26a96'], //just used a random token address, LOF in this case
addresses.recipient,
Date.now() + 1000 * 60 * 10, //10 minutes
options
);
console.log(`Transaction hash: ${tx.hash}`);
const receipt = await tx.wait();
console.log(`Transaction was mined in block ${receipt.blockNumber}`);
}
init();
But I get the following error all the time:

When I look up the taransaction details at Bscscan it always says Status: Fail
and after a little bit of time
Warning! Error encountered during contract execution [execution reverted]
Could someone help me? I can not seem to locate where the error lies.
same here for some reason do u know the reason by any chance?
Same. Can't use that function. It works with Uniswap but not working with Pcs. Just use swapExactTokensForTokens + deposited WBNB.
