must buy to incentivize miners to add your transaction to a block. Read our ETH
Gas 101 article for a comprehensive overview of ETH gas, gas pricing, and the
challenges of estimating gas.

DO I NEED TO PAY GAS FOR MY TRANSACTION?

Yes, always. To transact on the Ethereum network, you are charged a fee, which
is paid out to a miner who processes and validates the transaction. It is
important to note that not all transactions will cost the same amount of gas.
Depending on the size of the transaction and the number of transactions actively
competing to be submitted on-chain, gas fees will vary.

HOW IS GAS CALCULATED ON ETHEREUM?

EIP-1559 changed how Ethereum transaction fees are calculated and where those
fees go. Instead of a singular Gas Price, you now have to pay attention to three
separate values:

 * The Base Fee, which is determined by the network itself, is the first value
   to be aware of. It is subsequently burned during the transaction.
 * A Max Priority Fee, which is optional, determined by the user, and is paid
   directly to miners.
 * The Max Fee Per Gas is the absolute maximum you are willing to pay per unit
   of gas to get your transaction included in a block. For brevity and clarity,
   we will refer to this as the Max Fee.

Calculations: Base Fee, Priority Fee, Max Fee.



WHAT IS GWEI?

Gwei is the smallest denomination of ETH that is equivalent to 1/1,000,000,000
of 1 ETH (1 ETH = 1,000,000,000 gwei). All transaction fees on the Ethereum
network are denominated in gwei.

WHY IS GAS SHOWN IN GWEI?

Since one unit of gwei is an extremely small amount of Ethereum (0.000000001
ETH), it is much simpler to interpret and transact in terms of gwei rather than
fractions of a fraction of ETH.

WHAT IS A BASE FEE?

The base fee is an algorithmically determined fee that users on the Ethereum
blockchain must pay to complete a transaction. The base fee is designed to help
smooth transaction fees and prevent sudden price spikes by targeting 50% full
blocks. Depending on how full the new block is, the Base Fee is automatically
increased (the block is more than 50% full) or decreased (the block is less than
50% full). Visit our blog to learn more about EIP-1559 base fees.

WHAT IS A PRIORITY FEE?

The Priority Fee is an 'optional' additional fee set by the user and paid
directly to miners to incentivize them to include your transaction in a block.
It is sometimes referred to as the miner tip. Users will always be charged their
Priority Fee. Visit our blog to learn more about priority fees.

WHAT IS A MAX FEE?

The max fee is the absolute maximum amount you are willing to pay per unit of
gas to get your transaction confirmed. It is an 'optional' additional fee that
is paid directly to miners, and incentivizes miners to include your transaction
in a block. By monitoring mempool data, Blocknative users can accurately set
their max priority fee to increase the chances that their transaction is
confirmed as fast as possible. Visit our blog to learn more about max fees.

WILL I BE CHARGED MY MAX FEE?

You are rarely charged your max fee.

WHAT IS THE ETHEREUM TRANSACTION GAS LIMIT?

The gas limit is the maximum amount of gas miners are authorized to consume to
complete a transaction. Visit our blog to read more on Ethereum transaction gas
limits.

WHAT’S THE DIFFERENCE BETWEEN EIP-1559 AND LEGACY GAS FEES?

EIP-1559 added complexity to the Ethereum gas fee marketplace compared to the
previous first-priced auction system. Users now have to factor in a multitude of
variables including base fee, priority fee, and max fee. Visit the Blocknative
blog to view our guide to EIP-1559’s impact on gas fee calculations.

WHEN ARE ETHEREUM GAS FEES LOWEST?

Ethereum gas fees are lowest when there is the least amount of competition in
the mempool. Users can monitor gas fees to receive ETH gas price alerts right in
their browsers through Blocknative’s gas price extension for Chrome, Brave, or
Firefox.

WHY ARE ETHEREUM FEES SO HIGH?

Ethereum fees are high when the network experiences a rapid spike in demand for
getting transactions submitted on-chain. A common cause of an Ethereum
transaction fees spike is a highly anticipated NFT release. During these drops,
it’s common for users to set high priority fees to be competitive for inclusion
in the subsequent blocks. Congestion builds in the mempool as more people try to
mint the NFT, causing base fees to rise due to blocks being more than 50% full.
You can see these public gas auctions in action in our presentation How
Everything (and Nothing) Changes With Gas Fees.

Blocknative’s ETH Gas API Platform leverages real-time mempool data to help you
maximize predictability, and avoid overpaying when gas fees are high.



IS GAS REFUNDED FOR FAILED TRANSACTIONS ON ETHEREUM?

No, gas is not refunded for failed transactions on Ethereum, since miners had to
use resources to process the transaction before it ultimately failed. However,
any excess gas will be refunded to the originator. Learn more about Ethereum
transaction errors and how to avoid them.

CAN I TRACK ETH GAS FEES AND GET NOTIFICATIONS?

You can track ETH gas fees live with Blocknative’s Gas Estimator, available
through the web version, or as a browser extension for Chrome, Brave, and
Firefox. Sign up for a free Blocknative account to be instantly alerted any time
gas falls below a specified price directly through your extension.

DOES YOUR GAS ESTIMATOR HAVE REVIEWS?

Yes, our extension is rated 4.7 out of 5 with over 40,000 users on the Chrome
Web Store.
