Since the Ethereum blockchain is decentralized, there is no one “in charge” of it. This means that there is no customer service to contact if you have a problem.
It also means that there is no one to set gas prices or to determine how much gas should be used for a particular transaction.
This can be confusing for people who are new to Ethereum. How do you know how much gas to use for a transaction? How do you know what the gas price is?
The good news is that there are some tools that can help you with this. MyEtherWallet, for example, has a “Gas Tracker” feature that shows you the current gas prices and estimated gas costs for different types of transactions.
Another option is to use an Ethereum block explorer like EtherScan.io.
This website shows you all of the recent transactions that have been made on the Ethereum blockchain. You can use this information to help you estimate how much gas you will need for your transaction.
Once you have an estimate of how much gas you need, you can use a tool like MyEtherWallet to send your transaction. MyEtherWallet will automatically calculate the gas price based on the current prices and send your transaction with the appropriate amount of gas.
Of course, you don’t have to use MyEtherWallet or EtherScan.
There are many other options available, and new ones are being developed all the time. The important thing is to find a tool that works for you and that you feel comfortable using.
