Blockchain Client
Library: @solana/web3.js
Version: 1.x
Reason: Official SDK for transactions & program interaction
Documentation: https://solana-labs.github.io/solana-web3.js/
License: MIT
Secure Key / Session Storage
Library: Expo Secure Store
Reason: Encrypted storage for non-sensitive session data
Documentation: https://docs.expo.dev/versions/latest/sdk/securestore/
Forms / Validation
Library: React Hook Form
Validation: Zod
Reason: Performance & predictable validation behavior
- Backend Stack (On-Chain Logic) Blockchain Platform
Platform: Solana
Networks: Devnet (development), Mainnet (production)
Reason: High throughput, low fees, fast confirmation times
Smart Contract Layer
Language: Rust
Framework: Anchor
Reason: Safer program development, IDL generation, reduced boilerplate
Documentation: https://www.anchor-lang.com/
License: Apache 2.0
Program Design
Model: Program Derived Addresses (PDAs)
Reason: Deterministic accounts & secure rule enforcement
NFT Standard / Metadata
Standard: Metaplex Token Metadata Program
Reason: Solana ecosystem compatibility for NFTs
Documentation: https://docs.metaplex.com/
Decentralized Storage
Options: Arweave / IPFS
Use Cases: NFT metadata, ticket artwork, event details
- DevOps & Infrastructure Version Control
System: Git
Platform: GitHub
Branch Strategy:
