5. Smart Contract Specification

Data Structure

struct TransferStruct {
    address sender;      // Transaction initiator
    address receiver;    // Recipient address
    uint256 amount;      // Amount in wei
    string message;      // User-provided message
    uint256 timestamp;   // Block timestamp
    string keyword;      // Category keyword
}

Functions

• publishTransaction()— Records a new swap on-chain
• getAllTransactions()— Returns complete transaction history
• getTransactionCount()— Returns total transaction count
