Rotare Finance
Rotare Finance revolutionizes traditional Rotating Savings and Credit Associations
Problem Statement
Rotare FinanceRotare Finance is a Decentralized Rotating Savings and Credit Association (ROSCA) platform built on the Citrea Testnet (Bitcoin L2) that reimagines one of the worldโs oldest and most widely used financial models โ community savings groups.For centuries, ROSCAs have provided financial inclusion to millions of people who lack access to formal banking systems. They work by pooling contributions from members on a recurring basis and distributing funds to participants in turns. While effective, traditional ROSCAs suffer from trust issues, lack of transparency, zero yield on locked funds, and high coordination overhead.Rotare Finance solves these pain points by bringing ROSCAs on-chain and enhancing them with DeFi-powered yield generation, transparent Dutch auctions, and automated smart contracts. The platform is designed to be accessible, fair, and yield-generating โ democratizing collaborative finance while leveraging the security of Bitcoin and the programmability of EVM-compatible contracts on Citrea.๐ What Makes Rotare Finance Unique?On-Chain Transparency โ Every contribution, payout, and auction result is verifiable through smart contracts, eliminating the need for blind trust.Yield-Generating Pools โ Unlike traditional ROSCAs, pooled funds are deployed into DeFi protocols, generating 8โ15% APY while members wait their turn.Dutch Auctions for Early Access โ Members can bid for early fund withdrawals via a fair and transparent Dutch auction system, ensuring optimal price discovery.Bitcoin L2 Advantage โ Built on Citrea, Rotare Finance inherits Bitcoinโs unmatched security while enabling smart contract programmability.Safety & Governance โ Multi-signature controls, emergency withdrawals, and slippage protection provide strong user safeguards.๐๏ธ How It WorksPool Creation & Membership โ Users connect their wallet, configure contribution schedules, and join savings pools.Contributions & Yield โ Members deposit funds periodically, which are automatically deployed into DeFi protocols to earn competitive yields.Dutch Auctions โ Any member can participate in a transparent bidding process to gain early access to funds. Winning bids are distributed fairly via smart contracts.Payouts & Tracking โ At each cycle, funds (plus yield) are distributed to members, with all records visible on-chain.๐ Key FeaturesCollaborative Pools โ Flexible durations (3โ24 months) and contribution schedulesReal-Time Dashboard โ Track yield, contributions, auctions, and payoutsSecurity First โ Multi-sig governance, emergency exit, rate limitingCross-Chain Potential โ Roadmap includes support for BTC, ETH, and DeFi strategies across multiple chainsScalability โ Designed for both small community savings groups and large institutional adoption๐ Market OpportunityROSCAs represent a $2.5 trillion global market, heavily used in Africa, Asia, and Latin America.By moving these community finance models on-chain, Rotare Finance unlocks global accessibility, yield generation, and financial transparency.It also appeals to DeFi-native users seeking new yield strategies and traditional savings groups who want secure, digital-first alternatives.๐ฃ๏ธ RoadmapPhase 1 (MVP) โ Core ROSCA smart contracts, Citrea deployment, dashboard (โ Done)Phase 2 (Growth) โ Multi-asset support, advanced yield farming, governance token (๐ง In progress)Phase 3 (Scale) โ Cross-chain bridges, institutional adoption, white-label ROSCA solutions, mobile app (๐ฎ Planned)๐ Why Rotare Finance?Rotare Finance is pioneering the first DeFi-powered ROSCA platform, bridging the gap between centuries-old community savings practices and the modern decentralized financial ecosystem. By combining DeFi yield generation, Dutch auctions, and Bitcoin-secured execution, we are unlocking a new era of trustless, yield-bearing, and globally inclusive collaborative finance.
Solution
Rotare Finance was built by combining the old idea of community savings groups with the new world of blockchain and DeFi. Hereโs how we put it all together:Frontend (User Side): We used React + TypeScript with Tailwind CSS and Framer Motion to build a clean, simple interface. This makes it easy for anyone to join savings pools, track their contributions, and see how their money is growing.Smart Contracts (Brains of the System): We wrote Solidity contracts that handle everything โ contributions, auctions, payouts, and yield distribution. These contracts make sure the system runs automatically and transparently without needing to trust a middleman.Blockchain (Where It Lives): The contracts are deployed on Citrea Testnet, a Bitcoin Layer 2 chain. This gives us the best of both worlds โ Bitcoinโs security and Ethereum-style smart contracts.DeFi Integration (Money at Work): Instead of funds just sitting idle, we connect them to DeFi protocols (like lending pools and yield farms). That way, members earn interest (APY) while waiting their turn in the ROSCA.Wallet & Web3 Tools: We used Wagmi + Viem for wallet connections and blockchain interactions. This lets users easily join pools, sign transactions, and participate in auctions directly from their wallets.Architecture in Action:A user creates or joins a savings pool.Smart contracts handle deposits and lock funds safely.Funds are deployed into DeFi to generate yield.Members can bid in Dutch auctions if they need early access.Payouts are handled automatically, with everything recorded on-chain.In short: we built Rotare Finance to feel like a modern app on the outside but run completely trustless and decentralized under the hood.
