描述
Objective
Integrate the Polygon (Ethereum Layer 2) blockchain network to enable on-chain transactions for ChamaaChain’s savings and governance features.
Why Polygon?
Polygon offers fast, low-cost, and eco-friendly transactions—perfect for micro-savings and DAO governance in emerging markets.
Key Tasks
- Configure Polygon testnet (Mumbai) connection using Alchemy or Infura.
- Deploy a simple smart contract for on-chain savings records.
- Implement a service (via Ethers.js or Nethereum) to interact with the contract.
- Store transaction hashes in the backend DB (PostgreSQL).
Tech Stack
- Smart Contracts: Solidity
- Integration: Ethers.js / Nethereum
- Blockchain Network: Polygon (Mumbai Testnet)
- Backend: NestJS API
Acceptance Criteria
- Successful deployment of the smart contract on Polygon testnet.
- Backend can read/write on-chain transactions.
- Each user’s transaction hash is stored and retrievable from the database.
- Tested end-to-end with mock savings and governance data.

Future Extension
After testnet validation, migrate to Polygon mainnet and expand smart contracts to include loan approval and voting modules.
