Gas estimation failed

[kumarbitindi]

hi i am trying it on BSC network and using https://api.owlracle.info/v3/bsc/gas this for gas

import { ChainId } from "@0x/contract-addresses";
import axios from "axios";
import { ethers } from "ethers";

export const getGasEstimation = async (chainId: ChainId) => {

if (chainId === ChainId.BSC) {
const gasEstimation = await (await axios.get('https://api.owlracle.info/v3/bsc/gas')).data['speeds'];
// solution presented at ethers-io/ethers.js#2828
const maxFeePerGas = ethers.utils.parseUnits(
Math.ceil(gasEstimation.maxFee) + '',
'gwei'
)
const maxPriorityFeePerGas = ethers.utils.parseUnits(
Math.ceil(gasEstimation.maxPriorityFee) + '',
'gwei'
)
return { maxFeePerGas, maxPriorityFeePerGas }
}

return {}
}

[JoaoCampos89]

Swap api not works well with tokens with taxes, you need to use a higher slippagePercentage to help it cover the tax fee

[JoaoCampos89]

You don't need to change the gas fee logic for BSC, it should solve the issue when you put a higher slippage
