ARC (Algorand Request for Comments) standards define conventions for encoding, method calls, and application specifications on Algorand. This skill covers the most essential ARCs for smart contract development.

| ARC-4 | Application Binary Interface (ABI) | All smart contract method calls, type encoding | | ARC-22 | Read-only method annotation | Methods that don't modify state | | ARC-28 | Event logging specification | Emitting structured events | | ARC-32 | Application Specification (deprecated) | Legacy app specs (use ARC-56 instead) |

| ARC-56 | Extended App Description | Modern app specs with full contract metadata |

Implement Algorand ARC standards in smart contracts and clients. Use when needing to understand ARC-4 ABI encoding or method signatures, working with application specifications (ARC-32 or ARC-56), calling ARC-4 methods from contracts or clients, encountering ABI encoding/decoding issues, or generating typed clients from app specs. Strong triggers include "What is ARC-4?", "How do I encode ABI arguments?", "What's the difference between ARC-32 and ARC-56?", "method selector not matching", "application specification", "arc56.json".
