Development of Smart Contracts & NFT Logic

Milestone Outputs

The main deliverable in this milestone will be a fully functional set of smart contracts written in Plutus V2, implementing the logic for minting, updating, and managing tiered CIP-68 NFT Membership Passes. The outputs will include:

1. Minting Contract – Enables initial creation of NFTs when customers join the program, assigning the correct tier (Silver, Gold, Platinum) and initializing dynamic metadata fields.
2. Metadata Update Contract – Allows restaurants to update NFT metadata after qualifying events (e.g., customer visit, spend threshold met). Updates will be performed via authenticated transactions signed by the restaurant’s private key to prevent unauthorized modifications.
3. Tier Upgrade & Downgrade Logic – Smart contract rules that allow NFT tier changes based on loyalty points, visits, or spend, automatically updating benefits in the metadata.
4. Perk Redemption Logic – On-chain mechanism to mark perks as redeemed and prevent double usage while still preserving historical perk records in metadata for transparency.
5. Revocation & Transfer Support – Logic to revoke an NFT (e.g., for lost/stolen wallets) and reissue to a new address, as well as safe transfer protocols to ensure perks remain tied to the NFT and not an off-chain account.
6. Test Scripts & Simulations – Plutus Playground and Cardano testnet scripts for simulating key flows such as minting, metadata updates, and perk redemption. All contract code will be stored in a version-controlled GitHub repository, ensuring future audits and improvements.

Acceptance Criteria

The milestone will be accepted when:

• Smart contracts compile without errors in the targeted Plutus version, following Cardano best practices and security guidelines.
• CIP-68 compliance verified by testing against standard metadata parsers in popular Cardano wallets (Eternl, Lace, Nami).
• Authenticated metadata updates confirmed through simulated transactions, ensuring only the restaurant’s whitelisted signing keys can trigger updates.
• Full perk lifecycle tested — from NFT minting to metadata change to redemption flagging, with state transitions correctly reflected on-chain.
• Gas & fee optimization tested to ensure each transaction (mint/update/redeem) remains low-cost, suitable for frequent customer engagement.
• Internal code review completed by at least two independent Cardano smart contract developers.
• Stakeholder sign-off achieved with a live demo of NFT creation and updates on Cardano testnet.

Evidence of Completion

Evidence will consist of:

1. GitHub Repository containing complete Plutus V2 contract code, unit tests, and integration scripts.
2. Testnet Transactions — TX IDs demonstrating NFT minting, metadata updates, and perk redemptions on the Cardano testnet, all verifiable via Cardano Explorer.
3. Technical Documentation — Markdown or PDF files describing contract architecture, entry points, parameters, and how to interact via CLI or dApp.
4. Code Review Reports — Peer review feedback from at least two experienced Cardano developers, confirming adherence to coding standards and security best practices.
5. Live Demo Recording — A short video walkthrough showing the contracts in action, from minting an NFT to updating its perks in response to a simulated POS event.
6. Audit Readiness Checklist — Internal checklist verifying that the contracts meet minimal audit preparation standards before moving to production phases.

HR Portal & Proof Generator

Milestone Outputs

This milestone delivers a fully functional web-based HR Portal for restaurants and fine-dining venues, along with a Proof Generator module enabling customers to selectively disclose NFT perks in a privacy-preserving way. The HR Portal will serve as the operational backbone for restaurant managers to manage member perks, monitor NFT tier upgrades/downgrades, and trigger metadata updates. Core outputs will include:

1. Admin Dashboard – Role-based access for restaurant managers to view the full membership list, track perk usage, and trigger approved metadata updates to NFTs.
2. Proof Request Module – Allows restaurants to request cryptographic proof from customers that their NFT includes specific perks (e.g., “Free Dessert”) without revealing unrelated benefits or historical data. This leverages off-chain generation of proofs tied to the NFT metadata hash.
3. Selective Disclosure Flow – Customers will connect their wallet via the dApp interface, choose which perks to reveal, and generate a signed proof that can be scanned or verified by the restaurant.
4. POS/Booking Integration Hooks – API endpoints enabling the HR Portal to connect with restaurant POS or booking systems, automatically updating NFT metadata after a visit or purchase.
5. Activity Logs & Audit Trail – A secure, append-only log of all perk updates, proof requests, and tier changes, stored off-chain for compliance but linked on-chain via transaction IDs.
6. Front-end UI – Responsive, mobile-friendly interface using React or Vue, integrated with Cardano wallet connectors (Nami, Eternl, Lace).

Acceptance Criteria

This milestone will be deemed complete when:

• HR Portal is live on a secure test server, accessible to partner restaurants with role-based login.
• Proof Generator successfully creates verifiable signatures for selective perk disclosure, validated via an independent verification script.
• POS/Booking system integration tested with at least one mock API, automatically triggering NFT metadata updates upon simulated customer check-out.
• All user flows (proof request, metadata update, tier change) work seamlessly end-to-end with NFT smart contracts developed in Milestone 2.
• Security testing completed for authentication, signature verification, and prevention of unauthorized perk updates.
• Full UX walkthrough validated by at least one pilot restaurant partner, ensuring that the process is intuitive and does not disrupt normal operations.
