implement-arc-standards

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".
