Go estimate ethereum transaction gas limit and add 30% percent

estimate_gas.go

package main

import (
	"context"
	"fmt"
	"log"

	ethereum "github.com/ethereum/go-ethereum"
	"github.com/ethereum/go-ethereum/common"
	"github.com/ethereum/go-ethereum/ethclient"
)

func main() {
	client, err := ethclient.Dial("https://rinkeby.infura.io")
	if err != nil {
		log.Fatal(err)
	}

	tokenAddress := common.HexToAddress("0x90F8bf6A479f320ead074411a4B0e7944Ea8c9C1")
	estimatedGas, err := client.EstimateGas(context.Background(), ethereum.CallMsg{
		To:   &tokenAddress,
		Data: []byte{0},
	})
	if err != nil {
		log.Fatal(err)
	}

	gasLimit := int(float64(estimatedGas) * 1.30)
	fmt.Println(gasLimit) // 27305
}

Why * 1.3?
Thanks!

@aemet93 it's an arbitrary multiplier to make sure transaction goes through quickly. This snippet is outdated and now transactions require max base fee and priority fee

@miguelmota thanks for the answer. As I understand, that priority and etc should be set by client.
Now I need to estimate transaction (gas price and gas limit) on the backend and send it to client (to build raw tx).
And I used for it EstimateGas and SuggestGasPrice(), is it wrong?
