What this skill does
NEAR Smart Contracts Development Comprehensive guide for developing secure and efficient smart contracts on NEAR Protocol using Rust and the NEAR SDK (v5.x). When to Apply Reference these guidelines when: Writing new NEAR smart contracts in Rust Reviewing existing contract code for security and optimization Implementing cross-contract calls and callbacks Managing contract state and storage Testing and deploying NEAR contracts Optimizing gas usage and performance Getting Started Prerequisites Install the required tools before starting development: Create a New Project CRITICAL: ALWAYS run cargo near new to create new projects. NEVER manually create Cargo.toml, lib.rs, or any project files. The command generates all required files with correct configurations. Why cargo near new is mandatory: Generates correct Cargo.toml with proper dependencies and build settings Creates proper project structure with src/lib.rs template Includes integration test setup in tests/ directory Configures release profile with overflow-checks = true Sets up correct crate-type for WASM compilation Avoids common configuration mistakes that cause build failures DO NOT: Manually create Cargo.toml Manually create src/lib.rs Copy-paste project structure from examples Skip this step and create files directly Project Structure Deploy to Testnet Rule Categories by Priority Priority Category Impact Prefix --------- ---------- -------- --------- 1 Security & Safety CRITICAL security- 2 Contract Structure HIGH structure- 3 State Management HIGH state- 4 Cross-Contract Calls MEDIUM-HIGH xcc- 5 Contract Upgrades MEDIUM-HIGH upgrade- 6 Chain Signatures MEDIUM-HIGH chain- 7 Gas Optimization MEDIUM gas- 8 Yield & Resume MEDIUM yield- 9 Testing MEDIUM testing- 10 Best Practices MEDIUM best- 1. …
