Feedana follows a decentralized architecture with three core layers:
- React Application - Modern React 18 with hooks and component-based architecture
- Wallet Integration - Solana wallet adapter for seamless Web3 connectivity
- State Management - Redux Toolkit for global application state
- Solana Network - High-performance blockchain for board ownership and transactions
- Anchor Program - Smart contract framework for program logic
- Program Derived Addresses (PDAs) - Deterministic accounts for board management
The smart contract implements 5 core instructions with comprehensive validation and fee collection:
create_feedback_board- Initialize new feedback boards with metadata and IPFS integration (Platform fee: 10 lamports)submit_feedback- Process anonymous feedback submissions and update IPFS storage (Platform fee: 1 lamport)upvote_feedback- Users can upvote feedback with IPFS updates (Platform fee: 1 lamport)downvote_feedback- Users can downvote feedback with IPFS updates (Platform fee: 1 lamport)archive_feedback_board- Creator-only board archival to prevent new interactions while preserving data (No fee)
- Archive Protection: Prevents voting and feedback submission on archived boards
- Creator Authorization: Only board creators can archive their boards
- IPFS Validation: Comprehensive CID format and length validation (32-64 chars, must start with "Qm" or "b")
- Platform Fee Collection: Automatic fee transfer to platform wallet
96fN4Eegj84PaUcyEJrxUztDjo7Q7MySJzV2skLfgchY - Event Emission: All actions emit blockchain events for tracking and analytics
pub struct FeedbackBoard {
pub creator: Pubkey, // Board creator's wallet address (32 bytes)
pub ipfs_cid: String, // Current IPFS content identifier (4 + up to 64 bytes)
pub board_id: String, // Unique board identifier (4 + up to 28 bytes)
pub is_archived: bool, // Archive status flag (1 byte)
}The program implements 15 comprehensive error types:
