💡 Xitique Onchain — Decentralized Community Savings on Hedera

"Because saving together is part of our culture — and now it’s part of the blockchain."

Xitique Onchain is a decentralized community savings contract (ROSCA model) built on Solidity.
It enables groups to contribute stable amounts in USDT/USDC, rotating payouts to members based on various mechanisms.

🎯 The Problem

Across Africa, millions of people rely on informal community savings systems — known as Xitique, Stokvel, or Tontine — to pool funds and help each other save and access small loans.

However, these traditional systems face critical challenges:

• ❌ Lack of transparency — members must trust one coordinator.
• ⚠️ Risk of fraud or mismanagement.
• 🕒 Manual and time-consuming contribution process.
• 🌍 Diaspora communities struggle to participate remotely.

In short, the system works — but trust doesn’t scale.

💡 The Solution — Xitique Onchain

Xitique Onchain transforms Africa’s traditional community savings model into a transparent, automated, and trustless Web3 experience, powered by Hedera Smart Contracts.

It’s a decentralized ROSCA (Rotating Savings and Credit Association) that:

• Automates contributions and payouts in stablecoins (e.g., USDC).
• Eliminates the need for a human coordinator.
• Guarantees fairness and transparency through on-chain logic.
• Enables global participation — diaspora members can join from anywhere.
• Records all actions immutably on the Hedera network.

Trust is no longer personal — it’s programmable.

⚙️ How It Works

1. Create or Join a Group
   Define the contribution amount, frequency, and maximum number of members.

2. Contribute Automatically
   Members deposit stablecoins into the group’s smart contract.

3. Receive Payouts
   Each round, one member receives the pooled funds, determined by:

   • Rotation (default)
   • DAO Voting (for emergencies)
   • Auction (highest bid wins priority)

4. On-Chain Reputation
   Members earn trust scores based on their contribution history.

5. Auto-Restart or Close
   Once all rounds are complete, the group can restart or end automatically.

💰 DeFi Integration (Future Phase)

Idle funds between rounds can be invested in DeFi protocols (like Aave) to generate yield, increasing group value and rewarding active members.
