Скачать или смотреть NEAR SDK Part 2 (Payable, Private, and PanicOnDefault). 🦀Rust Smart Contracts

🔐 In Part 2 of the NEAR SDK series, we dive deep into the security attributes that prevent 90% of contract vulnerabilities:

✅ #[derive(PanicOnDefault)] – Prevent uninitialized contract disasters
✅ #[payable] – Accept NEAR payments safely in your functions
✅ #[private] – Restrict access to contract-only calls

By the end of this tutorial, you'll know how to initialize contracts safely, handle NEAR deposits correctly, and implement proper access control. These attributes are non-negotiable for production-ready NEAR smart contracts.
