The $2 Trillion Trust Problem

RizqFi solves the fundamental trust problem in Rotating Savings and Credit Associations (ROSCAs) - a traditional financial system used by over 1 billion people globally with $2+ trillion in circulation.

What are ROSCAs/Committees?

Traditional committees work like this: 10 friends each contribute $100 monthly. Each month, one member receives the full $1,000 pool until everyone gets their turn. It's crowdfunded savings + forced discipline.

The Critical Problems:

1. Fraud & Default ($2B+ lost annually)

   • Organizers disappear with funds
   • Members stop contributing after receiving payout
   • No legal recourse in most jurisdictions

2. Lack of Transparency

   • Manual tracking prone to errors
   • Disputes over who received payout when
   • No audit trail

3. Limited Access

   • Requires physical proximity
   • Restricted to tight-knit communities
   • Excludes digital-first populations

How RizqFi Solves This:

✅ Trustless Execution: Smart contracts automatically enforce contributions and payouts - no human intermediaries

✅ Complete Transparency: All transactions on Base blockchain - immutable audit trail viewable by all members

✅ Automated Enforcement: Can't receive payout without contributing. Can't skip rounds. Rules encoded in Solidity.

✅ Global Access: Works across borders with USDC stability. Basenames create familiar social trust layer.

✅ Privacy + Security: Private committees with invite codes. Only members see committee details.

Real-World Impact:

For Immigrant Communities: Send money home collectively while building local savings

For Unbanked Populations: Access structured savings without traditional banking

For Savings Groups: Eliminate fraud risk while maintaining community spirit

For Diaspora Networks: Coordinate cross-border collective finance trustlessly

RizqFi takes a proven financial model and makes it fraud-proof, transparent, and accessible to anyone with a wallet.

Technical Challenges Overcome

1. Multi-Phase State Management ⚡

Problem: Committees transition through phases (Joining → Deposit → Payout → Next Round) with complex state dependencies.

Solution: Implemented a robust state machine in Solidity with time-based automatic transitions and manual override functions. Used enums for phase tracking and validation modifiers to ensure state integrity.

enum Phase { Joining, Deposit, Payout, Completed }

modifier onlyInPhase(uint256 _id, Phase _phase) {
    updatePhase(_id);
    require(committees[_id].phase == _phase, "Wrong phase");
    _;
}

2. USDC Approval Flow on Production 🔄

Problem: Two-step transactions (approve → create) weren't working on Vercel deployment, causing "params[0].to is required" errors. Worked fine locally.

Solution: Implemented proper transaction state management with separate tracking for approval and creation steps. Added

reset()

3. Basename Integration for Identity 👤

Problem: Needed to display human-readable names instead of addresses, but had to work across Base mainnet (for Basenames) and Sepolia (for testing).

Solution: Configured OnchainKitProvider with Base mainnet for name resolution while keeping contract interactions on Sepolia. Used dynamic chain detection to show correct network warnings.

4. Private Committee Access Control 🔒

Problem: Needed invite-only committees while keeping public committees discoverable, without exposing private committee details.

Solution: Implemented

canViewCommittee()

5. Payout Rotation Fairness 🎯

Problem: Ensuring fair rotation where everyone gets exactly one payout, no duplicates, no skips.

Solution: Used

nextPayoutIndex

hasReceivedPayout

6. Real-time UI Updates 🔄

Problem: Users needed to see committee state changes (phase transitions, new members) without manual refresh.

Solution: Implemented 5-second polling with Wagmi's

refetch()

7. Environment Variables in Production 🌍

Problem: Contract address undefined on Vercel despite working locally.

Solution: Added environment variables via Vercel CLI, forced rebuild with

--force

Key Learning

Building a production-ready dApp requires thinking beyond smart contract logic - transaction UX, state management, and deployment configurations are equally critical. Every "it works locally" bug taught valuable lessons about Web3 production environments.
