Orbita

Orbita (https://0xorbita.xyz/) is a lending protocol deployed on World Chain that solves one of DeFi's longest-standing problems: undercollateralized lending. By integrating World ID verification, Orbita creates a tiered borrowing system where verified unique humans unlock better interest rates, higher loan-to-value ratios, and access to an undercollateralized lending tier that is unavailable to unverified users.
The core problem is simple. Traditional DeFi lending requires overcollateralization because there's no way to trust anonymous borrowers. Orbita changes this by using World ID as a sybil-resistance layer. If the protocol can verify you're a real, unique person, it can extend more favorable and even undercollateralized loan terms, bridging the gap between DeFi capital efficiency and TradFi-style credit access.
Users verify with World ID, supply collateral (e.g. WETH), borrow against it (e.g. USDC), and can perform collateral swaps within the protocol. The entire backend orchestration, including real-time price feeds and automated liquidation monitoring, is handled by Chainlink CRE workflows running autonomously.

Orbita's smart contracts are written in Solidity and deployed on World Chain testnet. The frontend is built with Next.js and integrates the World ID SDK for on-chain identity verification.
The backend orchestration runs on Chainlink CRE (Compute, Runtime, Environment) with two core workflows. The data-feed-workflow pushes price updates for USDT, WETH, WBTC, and the native token through on-chain oracle contracts, each confirmed as individual transactions on-chain. The liquidate-workflow discovers active lending pools from an indexer, iterates through borrowers, computes health factors based on borrow debt versus collateral limits, and triggers liquidations when positions fall below the safety threshold. Both workflows are simulated via the CRE CLI and designed for live deployment on the CRE network.
The stack includes Solidity for lending pool and oracle contracts, Chainlink CRE for workflow orchestration, World ID for identity verification, and Next.js/React for the frontend.
