Most Popular EVM API Methods
A comprehensive list of the most popular EVM API methods
Introduction
Knowing about the most popular API methods of the Ethereum Virtual Machine (EVM) can be valuable for developers looking to interact with smart contracts on the EVM blockchains. These methods allow for various actions such as querying contract data, retrieving transaction information, and checking the status of the blockchain. Understanding the capabilities and use cases of these popular methods can help you make informed decisions when building decentralized applications and interacting with the EVM networks. Additionally, this knowledge can also be useful for individuals looking to access and analyze blockchain data for analytics or research purposes.
On this page, you will find a list of some of the most widely used API methods for interacting with the EVM blockchains.
