WorlDate

Worldate is a transformative dating app developed as a World Mini App, basically rewriting the rulebook on digital romance with authenticity, intent, and dedication over surface volume being the priority. The creation is intended to address the major failures of existing dating platforms, like widespread fake profiles, catfishing, dating burnout, and low-fidelity interactions. They do so through the strong identity verification supplied by World ID. Each member has to sign in and prove their status as an original, verified human, virtually removing bots and scammers and creating a bedrock of trust among the millions of users in more than 160 nations.

The main new idea of Worldate is the Mutual WLD Staking mechanism, called StakeMatch. To use the chat feature with a match, both users need to Pay a set amount of the Worldcoin token(WLD). This money commitment makes sure that every chat starts with both users invested and serious, filtering out those who put in little effort like swiping or messaging casually. The staked money is kept safe through a smart contract on a blockchain that works with EVM. This creates a financial reason for respectful and serious behavior, which helps improve the balance between genders by reducing spam messages for women and enhancing the quality of matches for men. Sage Support - one of the Quick Actions from World mini-apps Sage is an AI chatbot that lets users ask questions and get answers, enhance their messages and get some good pickup lines to impress their Date!

How We Built WorlDate

We built WorlDate on the World Mini App framework using MiniKit. This gave us two big advantages right away: Instant access to World App users, so we didn’t have to build our own audience from scratch. Wallet Authentication as the primary auth flow, making it easy for users to log in securely while reducing fake accounts and fraud. This let us focus on what really matters , great matches and a smooth chat experience , instead of spending time on basic setup.

Tech Overview Frontend: The app is built with Next.js (App Router) and TypeScript. We use Tailwind CSS with shadcn/ui to quickly design a clean, responsive interface that’s easy to update.

Backend & Data: We use Drizzle ORM to manage our database with type-safe SQL and easy migrations. The backend is a lightweight Node/TypeScript service with APIs for login, match retrieval, staking, and messaging. Smart Matchmaking Our matching system uses a small machine learning pipeline: Collect signals like age, location, interests, and dating goals. Score potential matches with a mix of rules and a compact ML model. Use a re-ranker to keep results fresh and diverse. This gives users relevant matches without making them answer tons of questions.

AI Chat Support - “Sage Support” Inside the chat, we added Sage, a built-in AI assistant. Sage can: Suggest conversation starters Improve a message before sending Answer etiquette questions It uses conversation context (with strict safety filters) to help people chat more naturally and confidently.

WLD Staking for Mutual Interest To show interest, a user stakes 0.01 WLD. When both people stake, the chat unlocks. We use optimistic UI, so the action feels instant while we process it on-chain in the background. If the transaction fails, we roll back smoothly so the experience still feels seamless. Real-Time Chat

Messages are sent through WebSockets with support for images, GIFs, and emojis. Everything is saved in our database using the same typed SQL layer, making it reliable and auditable.
