10 Best Ethereum (ETH) APIs for Developers After the “Dencun” Upgrade

Since the “Dencun” upgrade on March 13, 2024

Since the “Dencun” upgrade on March 13, 2024, which brought in “Proto-Danksharding” (EIP-4844), Ethereum trading has stayed active—despite ETH not showing strong gains in this bull cycle yet.

The cryptocurrency is still a hot topic in the crypto community despite its price action, and it’s no surprise given the fact that the second-largest cryptocurrency is used by millions of users every day.
