A low-level call refers to a basic function or command execution interacting directly with the underlying protocol of a blockchain. It typically involves programming actions that are close to the hardware level, allowing for more control over processes.These calls often utilize smart contracts, where developers write code to perform specific tasks like transferring tokens or executing complex transactions. Low-level calls bypass higher-level abstractions, granting users and developers more flexibility and efficiency.Due to their close interaction with the blockchain’s infrastructure, low-level calls can lead to reduced overhead and faster execution times. However, they also require a solid understanding of the protocol to avoid bugs or vulnerabilities, making them suitable mainly for experienced developers.In contrast to high-level interactions, these calls provide more precise control, which can be essential for optimizing performance or executing complicated contracts. This makes them valuable for applications requiring specific functionality or enhanced security measures.
