InteractionLogger is a lightweight smart contract built and deployed on the Flow Testnet. The contract securely logs on-chain user interactions along with their timestamps — creating a transparent record of engagement for analytics, health tracking, or proof-of-presence applications.
Every call to the interact() function automatically stores the caller’s address and the time of interaction, ensuring verifiable and immutable event logging on Flow.
⚙️ Key Features 🧠 No Inputs Needed: Each user call is automatically captured — no parameters required. 🕒 Timestamped Logs: Each interaction includes both the user address and block timestamp. 🧾 Permanent On-Chain Record: Data is securely written to Flow’s decentralized ledger. 🚫 No Constructors or Imports: Fully self-contained for portability and reliability. 🔔 Event Emission: Each interaction emits an event for off-chain tracking.
