Quest Details

Introduction

In Solidity, calls refer to the mechanisms by which smart contracts interact with one another or with externally owned accounts (EOAs). These interactions can be categorized into high-level and low-level calls.

High-level calls, designed to be user-friendly, simplify complex tasks and abstract away many underlying details, making contract interactions more straightforward and secure. In contrast, low-level calls provide granular control over interactions, allowing for more customized and advanced operations.

In this tutorial, we’ll be learning all about the different types of calls, and in which scenarios each one should be used. Let’s go!
