MicroFi: Blockchain for Microfinance

In developing countries, one of the main ways for women to be financial indepedent is through microfinance loans. What if we made this simple and secure through a blockchain marketplace?

Inspiration

Women in South East Asia and many developing regions rely heavily on microfinance loans. As a CS and Econ double major, I had already read a lot about these systems, and it was obvious that there were too many issues: very high interest rates, slow transactions, limited transparency, and in some cases exploitation. None of it felt efficient or fair. Blockchain technology felt like the perfect match for solving these problems, so I wanted to try building a better version.

What it does

MicroFi is a blockchain based loans platform and marketplace. Borrowers can request a loan, and individual lenders can choose to fund a portion of that loan. It creates a way to support someone’s goals while also giving lenders the chance to earn. Everything runs through Solana, with smart contracts and an on chain ledger handling the backend. We also built an AI advisor that evaluates each borrower. The flow is simple: a borrower submits a request, the AI runs a risk assessment, the smart contract is created, lenders contribute, and the loan is released.

How I built it

We built a full stack application using the Gemini API for the AI advisor and Solana for all blockchain interactions. The system ties together the front end, the risk model, and the smart contract flow.

Challenges I ran into

Solana resources were not accessible on university WiFi, so I had to reach out on Slack and then switch to cellular data. Integrating both Solana and Gemini also took time since each required different setups and testing.

Accomplishments that we're proud of

I built a complex app that has real potential to support millions of people. I am also proud that we were able to dive into blockchain for the first time and actually make it work in a meaningful way.

What I learned

We learned how to integrate external systems like Solana and how to combine AI with blockchain in a practical workflow.

What's next for MicroFi: Blockchain for Microfinance

The next steps are extensive testing, onboarding our first users, and adding more safety and reliability features to make the platform ready for real communities.

Alignment with Technica's mission

MicroFi supports an inclusive tech community by making financial tools easier to access, safer to use, and more transparent for people who are often left out of traditional systems. Many women who rely on microfinance face high interest rates, slow processing, and unclear decision making. MicroFi gives them a clearer and more fair process with open smart contracts, simple workflows, and consistent AI based evaluations.
