The Starknet Foundation, in collaboration with RareSkills, has published a free e-book on advanced smart contract development on Starknet using the Cairo programming language.

Most code is written by agents instead of by hand. However, to manage coding agents effectively, developers must

Understand the design space afforded by the Starknet blockchain.
Be able to quickly read code the agents produce.
Write strong testing frameworks to prevent bugs from being introduced

Starknet offers stronger support for features such as account abstraction, batched transactions, and smart contract upgradeability compared to other solutions. Starknet also provides a strong developer tooling with Starknet Foundry.

However, if developers are unaware of the expanded design space Starknet offers, they might unintentionally copy outdated design patterns that they used previously. They might also miss opportunities to significantly improve end-user UX.

AI is a productivity tool, not a substitute for domain knowledge. Thus, the e-book goes beyond code examples and explains what happens “behind the scenes,” helping developers build a cohesive mental model of how their code interacts with the Starknet blockchain. This makes learning more engaging than memorizing a list of features.

“Our team did a fantastic job creating this e-book, which spans over 50,000 words. The team went above and beyond, even turning dry technical diagrams into animated schematics that convey the same information with less burden for the reader. I’m also grateful to the reviewers who built applications based on the provided resource to really tease out any aspects of the book that weren’t completely clear and compelling,” said Jeffrey Scholz, the founder of RareSkills.

“Rareskills did such a good job with their deep dive into Starknet’s technology that at the end, instead of reviewing the content, I ended up learning from it,” said David Barreto a Developer Advocate at the Starknet Foundation

The Starknet Foundation stewards the growth and development of the Starknet ecosystem by providing the tools, resources, and support needed to create transformative solutions that drive the adoption of a reinvented digital world.

RareSkills is a leading education provider for blockchain developers, with a focus on serving senior engineers, smart contract auditors, and CTOs. RareSkills provides numerous free learning resources for blockchain developers, and a coaching program for busy engineering professionals looking to carve out time for effective technical upskilling.
