In the rapidly evolving Agentic Economy, traditional long-term contracts and subscription models are plagued by trust issues and settlement risks. JoyKeep is a decentralized payment and risk control protocol designed to bridge this gap. We are shifting the paradigm from "long-term uncertainty" to "3-day certainty," providing the essential rails for verifiable, automated commerce. Core Mechanism: The 3-Day Slice Settlement At the heart of JoyKeep is our unique Slicing Plan. Instead of a lump-sum payment or a risky monthly subscription, JoyKeep locks the total budget into a secure Vault. Micro-Settlement: The protocol automatically divides the contract into 3-day "slices." Heartbeat Probing: Before each slice is released, the system performs a "heartbeat" check (PROBE_ATTEMPT) to verify service delivery via our PoE Handshake (Permissions Delivery Handshake Protocol). Atomic Release: Payment is only made to the seller after a successful probe, reducing the risk window to just 72 hours. Immediate Risk Stop-Loss & Compliance JoyKeep eliminates the need for manual audits in high-risk scenarios. Our "Stop Without Audit" logic ensures that if a "black card" or high-risk activity is detected: Service Stops: The merchant side immediately halts delivery. Settlement Freezes: The protocol stops all subsequent slice payments instantly. Only payments for successfully completed slices are retained, protecting both parties from escalating losses. JoyLaw: AI-Powered Dispute Resolution When conflicts arise, JoyLaw takes over. Our protocol invokes Multimodal AI (Gemini) to analyze evidence (text, screenshots, or logs) and outputs a structured JSON verdict. Verifiable Traces: Every step—from X402_PAID to PROBE_RESULT—leaves an auditable trace on the timeline. Automated Justice: If the AI determines evidence is sufficient and supports the buyer, a Dispute Probe is triggered. If the resource remains unavailable, a refund is automatically executed by the smart contract.

"Joykeep demonstrates innovative protocol design with its 3-Day Slice Settlement mechanism, Heartbeat Probing for service verification via PoE Handshake Protocol, and atomic payment releases only after successful service delivery. The protocol includes sophisticated risk management with "Stop Without Audit" logic for immediate service halts and settlement freezes upon detecting high-risk activities. Key strengths include the comprehensive automated dispute resolution system (JoyLaw) using Multimodal AI (Gemini) for evidence analysis and structured JSON verdicts, plus complete auditability with verifiable traces for every transaction step. For improvement, consider implementing more granular risk scoring beyond binary "black card" detection, adding predictive analytics for early risk identification, expanding the AI dispute resolution to handle more complex scenarios, and creating a reputation system for merchants to build trust over time.

"Very good project but the implementation is still in basic starting level. Can be understood since this is a hackathon mvp. Has good potential"
