Description

ChainCircle is a decentralized savings platform built on Push Chain that brings traditional Rotating Savings and Credit Associations (ROSCAs) on-chain. The platform enables users from different blockchains (Ethereum, Solana, Push Chain) to participate in collaborative savings circles without bridging or network switching.

Users can create or join savings circles where members contribute fixed amounts periodically, and each member receives a payout once per cycle. The platform features a reputation system with four tiers (None, Bronze, Silver, Gold) that rewards consistent participation, automated yield generation at 4% APR, and soulbound NFT badges for achievements.

Key innovations include universal blockchain access powered by Push Chain's universal transaction layer, social accountability through friend-based circles, democratic governance for emergency withdrawals, and a gamified experience with streak tracking and bonus points. The platform includes a public faucet for testnet CUSD tokens and a comprehensive name registry for improved user experience.

ChainCircle combines traditional community savings wisdom with blockchain technology to create a transparent, automated, and accessible savings solution.

Progress During Hackathon

Successfully deployed complete ChainCircle platform on Push Chain Donut testnet with seven smart contracts: ChainCircleCore (main logic), CUSD (token with faucet), ReputationManager (4-tier system), BadgeNFT (soulbound achievements), GovernanceModule (democratic voting), MockYield (4% APR), NameRegistry, and WalletPreferences. Built full-stack React frontend with dashboard, circle management, profile system, payout tracking, and notifications. Implemented comprehensive test suite with 52 passing tests covering all core functionality. Integrated Push Chain UI Kit for seamless wallet connectivity across chains. Deployed live demo at chaincircle.org with all features functional including circle creation, joining, contributions, automated payouts, reputation tracking, and NFT badge minting.
