DELEGO-Earn on Subs

Problem Statement

The Problem: The digital subscription economy, valued at over $1.5 trillion, is fundamentally inefficient. Consumers waste an estimated $348 billion annually on idle services, a "subscription sinkhole" where value simply vanishes. The alternative, sharing passwords with friends and family, is an insecure and messy process that creates friction for users and revenue loss for service providers. We are forced to choose between wasting our money or compromising our security.Our Solution: DELEGO fundamentally changes this relationship by transforming digital subscriptions into ownable, on-chain assets. Our web-based platform introduces two revolutionary features:Secure Sharing: Users can generate time-limited, revokable "Guest Passes" for others. Our system provides the guest with a unique, temporary session ID, meaning the owner's password and credentials are never exposed.A Liquid Marketplace: For the first time, users can rent out their unused subscription time on a peer-to-peer marketplace. A user on a 3-week vacation can now rent out their 21 days of a streaming service, turning a monthly liability into an income-generating asset.DELEGO is building the Airbnb for digital services—a trusted, user-centric marketplace that unlocks billions in wasted value and gives consumers true ownership of what they pay for.

Solution

Foundation & Blockchain: The entire platform is built on the Flow blockchain, a strategic choice for three key reasons:True NFT Ownership: We used Cadence to write our smart contracts. Its resource-oriented design is fundamentally safer for creating our subscription passes as true, ownable NFTs, preventing common exploits and giving users verifiable control over their assets.Marketplace Viability: Our model relies on frequent, low-value transactions. Flow's consistently low gas fees are essential to make renting a pass for a few dollars economically feasible.Consumer Onboarding: Flow's user-friendly account model allows us to design a seamless web experience where mainstream users can interact with NFTs without the typical friction of Web3.Architecture (On-Chain vs. Off-Chain): DELEGO uses a hybrid architecture to balance decentralization with a smooth user experience.On-Chain (Flow): The core logic for the subscription passes resides here. This includes the NFT contract for minting, transferring, and verifying ownership. All marketplace listings and rental agreements are governed by these on-chain assets.Off-Chain (Backend): We built a backend service (e.g., using Node.js/Express) that acts as a secure proxy and session manager. This service communicates with the Flow blockchain to verify NFT ownership. Its most critical function is to generate temporary, single-use session tokens for renters and guests. This allows us to grant access without the owner's actual credentials ever being stored or exposed on-chain.Frontend: The user interface is a responsive web application built with a modern framework like React/Next.js. It interacts with the Flow blockchain via the Flow Client Library (FCL) for wallet interactions and transaction signing, abstracting away the complexity for the user and making it feel like a familiar, intuitive web platform.
