Description

Goal: On-chain proof of savings (immutable record of member deposits).

Explanation: This contract handles how much each member contributes, time, and rules like minimum deposit. Ensures fairness and prevents tampering.

Key Functions:

  • deposit()

  • getMemberSavings(address member)

  • setMinimumDeposit(uint amount)

Deliverables:

  • contracts/SavingsContract.sol

  • Unit tests: deposit + query savings balance

Contributor guide

Research direction
Familiarize yourself with the project structure. Set up a Solidity development environment (e.g., Hardhat). Implement the three functions (deposit, getMemberSavings, setMinimumDeposit) in contracts/SavingsContract.sol. Write unit tests using a testing framework like Hardhat tests. Ensure the contract compiles and all tests pass.
