Arbitrum Pre-compiles Explained: A Beginner’s Guide to System-Level Contracts

This video gives a beginner-friendly introduction to pre-compiles on Arbitrum—what they are, how they work under Nitro, and how developers can interact with them using Solidity interfaces. You’ll learn the difference between regular smart contracts and pre-compiles, how Arbitrum implements system-level pre-compiles like ArbSys, ArbGasInfo and why they offer massive performance and gas-efficiency benefits. We also walk through simple coding challenges that help you interact with Arbitrum pre-compiles directly, letting you understand their real-world usage. Topics Covered: What pre-compiles are and why blockchains use them Native execution vs EVM execution Difference between smart contracts and pre-compiles Gas-efficiency and performance benefits How Arbitrum implements pre-compiles inside Nitro The role of Go code (implementation) vs Solidity interfaces Calling pre-compiles like ArbSys, ArbGasInfo How Nitro routes calls to pre-compile addresses On-chain execution vs where the code actually lives Example: calling L2 block number, gas info, retryables, etc. Coding challenges to interact with pre-compiles in your own smart contracts Useful Links: Try hands-on coding challenges on the XCan platform: https://modules.xcan.dev/challenges Arbitrum Nitro Pre-compiles Overview: https://docs.arbitrum.io/arbos/precom...
