Juby Passport
Juby is the first self-custody retirement Mini App for freelancers.
Problem Statement
The Problem: In Latin America, the freelance workforce is booming, but financially naked. Traditional pension systems are broken by inflation, and current crypto wallets are built for trading, not saving. This leads to panic-selling grants and zero long-term wealth accumulation.The Solution: Juby Passport is a World Chain native Mini App designed to automate financial stability for the gig economy. We transform the World App from a "claim & sell" interface into a "claim & build wealth" platform.Key Features:Verify: Uses World ID to create a unique "Proof of Savings" reputation, laying the groundwork for future under-collateralized loans.Grow: Direct access to institutional-grade yield vaults (modeled on Morpho Blue) without the complexity of DeFi dashboards.
Solution
Frontend & Integration: We built the frontend using the MiniKit SDK to ensure a fully native experience within World App. We focused heavily on "Calm UX," abstracting away gas fees and complex approvals to suit non-crypto-native freelancers.Identity: We integrated World ID verification as a mandatory step. This isn't just for login; it links the on-chain vault to a unique human, preventing bot farming and establishing a trusted financial history for the user.Smart Contracts (DeFi Architecture): We deployed our contracts on World Chain. Since Morpho Blue is not yet available on the World Chain Testnet, we architected and deployed a custom ERC-4626 Vault (MockMorphoVault.sol) that strictly replicates the logic and interface of a Morpho Vault.The Hack: To simulate the yield experience for the demo without live liquidity, we created a "yield injector" function in our contract that mathematically simulates share price appreciation based on block.timestamp. This allows the judges to see the "wealth accumulation" effect in real-time during the demo, proving the viability of our roadmap to integrate the real Morpho protocol on Mainnet.
