🏗SolChit Fund 3.0(Digital Committee) is a decentralized rotating savings protocol (ROSCA / Chit Fund) built on the Solana blockchain using Rust and the Anchor framework.
The protocol replaces the traditional trust-based chit fund organizer with deterministic on-chain logic, transparent accounting, and program-controlled vaults.
This project demonstrates full-stack Web3 architecture:
- On-chain smart contract in Rust
- SPL token (USDC) vault management
- Anchor-based program structure
- TypeScript client integration
- Next.js frontend with wallet connection
- ✅Phantom Wallet
- ✅Anchor Client (IDL-based interaction)
- ✅Solana Devnet
- ✅Rust Smart Contract (Anchor Program)
- ✅SPL Token Program (USDC transfers)
📦 Smart Contract Features
- ✅ Pool creation with configurable parameters
- ✅ Member registration and joining logic
- ✅ Periodic contribution validation
- ✅ SPL token vault-based fund custody
- ✅ Secure PDA-controlled treasury authority
- ✅ Deterministic accounting per member
- ✅ Anchor-based account constraints & validations
- ✅ Transparent and trustless fund rotation mechanism
