Rankers

Rankers is a platform designed to motivate personal growth and build better habits through gamified challenges and financial commitment. Here’s how it works: users join challenges by setting a goal, a timeline, and staking an initial deposit. Progress is tracked, and rewards are distributed based on performance—achieve 80% of your goal, and you earn 80% of your stake back. Top performers share the reward pool—the portion of funds left from unmet goals—while 50% of this pool is donated to NGOs promoting mental health, wellness, and social impact through sports and education. The platform ensures fairness, transparency, and automation through smart contracts, which manage deposits, track progress, and distribute funds securely.

Smart Contracts: Developed in Solidity, our smart contracts autonomously handle deposits, milestone tracking, and reward distribution on the Ethereum blockchain.

Frontend Framework: Built using Flutter, the platform delivers a seamless, cross-platform user experience for both mobile and web users, ensuring accessibility and a modern UI.

Blockchain Integration: Utilizing web3auth SDKs, we provide secure, wallet-less authentication, making it easy for users to onboard and interact with the blockchain without requiring prior technical knowledge.

Transaction Management: Leveraging Biconomy's Superfluid Transactions, we ensure gas-efficient and user-friendly staking, withdrawals, and reward distribution, minimizing friction in blockchain interactions.

Onramp / Offramp and Stake: Integrated with the Coinbase SDK, users can easily onramp and offramp funds using fiat-to-crypto or crypto-to-fiat conversions. Coinbase SDK is also used for staking operations, offering a streamlined and trusted experience.

Deployment: Hosted and deployed on Nouns, the platform ensures scalability and reliable access to blockchain nodes, enabling real-time interactions and robust performance and aligned with a strong social mission.
