Ethereum, the second-largest cryptocurrency by market capitalization, has been experiencing a flurry of activity following the “Dencun” upgrade on March 13, 2024. This upgrade introduced “Proto-Danksharding” (EIP-4844), which has sparked renewed interest in the Ethereum ecosystem. Despite ETH not showing significant gains in the current bull cycle, total trading volumes have surpassed $2 billion, indicating a high level of trading activity.
With the increasing demand for robust data tools to handle the growing activity on Ethereum and its layer-2 networks, several solutions have emerged to cater to this need. In this article, we will explore some of the top data tools available for Ethereum developers.
1. Bitquery API
