ETH Gas Tracker – Full Ethereum Gas Tracker Guide

When interacting with the Ethereum blockchain, you’re required to pay gas fees. These fees are known for being volatile, and the price is directly influenced by the network’s supply and demand of computational power. Consequently, during times of high network activity, it can be quite expensive to transact on the Ethereum blockchain. Fortunately, this is where tools like Ethereum gas trackers enter the equation, allowing crypto enthusiasts, traders, and Web3 developers to optimize transactions for cost-effectiveness and performance. But what exactly is an ETH gas tracker? And where can you find the best one? If you’re looking for the answers to these queries, follow along in this article as we explore the intricacies of ETH gas trackers!


In today’s guide, we’ll kick things off by diving into the intricacies of Ethereum gas trackers. In doing so, we’ll learn what they are, how they work, and why you might need them. From there, we’re going to dive straight into our ETH gas tracker list, where we’ll cover three prominent platforms: Etherscan, Blocknative Gas Estimator, and Cryptocurrency Alerting. Lastly, for those interested in Web3 development, we’ll top things off by introducing you to Moralis – the industry’s #1 tool for anyone looking to build blockchain analytics platforms and other Web3 projects!

Nevertheless, without further ado, let’s dive straight into the main topic and answer the question, ”What is an ETH gas tracker?”

What is an ETH Gas Tracker? 

Gas fees on Ethereum are known for being notoriously volatile, which is a direct effect of the dynamic interplay between supply and demand for processing power within the network. Consequently, when Ethereum is experiencing high activity, the demand for processing power exceeds supply, causing prices to surge. This has been a recurring issue on Ethereum, where the network has experienced astronomically high gas fees, rendering it economically unviable for many users to transact on the blockchain. 

So, how do users deal with these issues? And how are they mitigating gas fees on Ethereum?

Well, this is where ETH gas trackers enter the equation! 

Put simply, an ETH gas tracker is an application, website, or other platform monitoring and providing information about historical and current gas fees on the Ethereum network. With greater insight into the gas dynamics of Ethereum, users can leverage this data to make more informed decisions on when and how to carry out transactions. In return, this allows them to optimize the cost-effectiveness and performance of their Ethereum transactions! 

Nevertheless, to better understand ETH gas trackers and the utility of these tools, let’s take the following subsection to dive a bit deeper into gas fees on the Ethereum network! 

Gas Fees on Ethereum 

In the context of Ethereum, gas refers to the unit that measures the computational efforts required to execute certain operations on the Ethereum network. In short, it’s essentially the fuel that powers the network, much in the same way that a car relies on gasoline to run!

With that said, what exactly are Ethereum gas fees? 

Well, gas fees on Ethereum are made up of three distinct components: 

  • Base Fee: The base fee is set by the protocol, and it’s the least amount you must pay for your transactions to be considered valid.
  • Priority Fee: The priority fee is a tip that you add on top of the base fee, making it more attractive to validators so they choose it for inclusion in the next block. 
  • Units of Gas Used: More complex operations require more computational power. For instance, interacting with smart contracts uses more gas than sending simple transactions. 

What’s more, the formula for calculating Ethereum gas fees is: Units of gas * (base fee + priority fee).

Moreover, gas fees on Ethereum have to be paid in the chain’s native cryptocurrency, Ether (ETH). However, prices are typically denominated in Gwei – short for gigawei – which equals one billionth of an ETH (0.000000001 ETH). 

All in all, gas fees are what users pay to process transactions or smart contracts on the Ethereum blockchain. What’s more, these fees can change drastically in a short period depending on supply and demand factors. And one of the easiest ways to monitor and understand Ethereum gas fees is to use a tool like an ETH gas tracker!

Now, with an overview of Ethereum gas fees, let’s dive into our ETH gas tracker list to explore some existing platforms you can use!  

ETH Gas Tracker List 

There are multiple prominent ETH gas trackers available on the market for you to choose from, and we won’t be able to cover them all in this article. Consequently, in the following sections, we have put together an ETH gas tracker list comprising three industry-leading platforms: 

  1. Etherscan
  2. Blocknative Gas Estimator
  3. Cryptocurrency Alerting

However, the ETH gas trackers above are only three prominent examples. If you’d like to explore more platforms, check out our Web3 gas tools page on Moralis’ dapp store: Web3 Wiki

Nevertheless, without further ado, let’s dive straight into our first ETH gas tracker: Etherscan! 


Etherscan is a popular blockchain explorer and analytics platform that tracks and sorts data from the Ethereum blockchain into easily navigatable information. With Etherescan, it’s possible to seamlessly look through blocks, transactions, smart contracts, wallet addresses, and other on-chain-related data on the Ethereum network. Furthermore, one of Etherscan’s most prominent features includes the ETH gas tracker! 

Etherescan’s ETH gas tracker is one of the most popular tools for tracking Ethereum gas prices. With it, you can effortlessly access both real-time and historical ETH gas prices so you can make well-informed decisions on when and how to transact on the network. 

Moreover, Etherescan’s ETH gas tracker updates gas estimations every 15 seconds and provides features like a gas price heatmap, historical charts, and price estimates for various actions, such as swapping fungible tokens, NFT sales, and much more. 

Blocknative Gas Estimator 

Blocknative Gas Estimator is another prominent ETH gas tracker. This tool inspects all pending public Ethereum transactions, and leverages advanced machine-learning models to deliver accurate gas fee predictions. What’s more, Blocknative Gas Estimator offers free updates every five seconds. And commercial users can even get updated gas fee estimations once every second!

Furthermore, like Etherscan, Blocknative Gas Estimator also provides additional features, including historical heatmaps and charts for gas fees.
