Inspiration

Azina finance is inspired by the emergence of decentralized finance, DeFi. The new paradigm of offering financial services on the blockchain is the core concept behind Azina. Azina is a hybrid solution encompassing the expertise of traditional finance and virtues of decentralized finance.

What it does

Azina allows users to borrow local fiat against their crypto assets. Azina aims to address the following problems:

1. Complexies in USD-based crypto loans
   - Fluctuations in exchange rates
   - Overdependence on the P2P markets liquidity
   - P2P add additional risks and steps to the loan process

2. Misuse/ Loss of user collateral

How I built it

Azina is made up a couple of moving parts:

1. The UI/ Frontend
2. Web3 Providers
3. Backend API
4. Smart Contracts
5. Chainlink Services

The frontend: Built with Quasar Framework
Allows interaction with the smart contract and backend.
Through the frontend, users can request and manage their loans; however, due to the decentralized nature of Azina, the frontend is completely optional

Providers: QuickNode and MetaMask
Allow access to the blockchain

Backend API: Built with FastAPI and Deta Space
Performs Admin functions such as account verification
Allows Loan processing and Loan Management
It interfaces with payment service provider for fiat payments processing

Azina Loan Smart Contract: Built with Solidity
Manages Loan data
Holds collateral
Loan management such as liquidation, top up, withdraw excess collateral, repayments

Azina Verification Smart Contract: Built with Solidity
Azina is a permissioned service and therefore users must be verified.
The contract manages the verification of accounts.

Chainlink Services:

1. Automation:
   Checks if there is a loan to be liquidated. This protects the platform from bad debt
   Loans are liquidated via Spookyswap

2. Data Feeds:
   Provides the Azina loan smart contract with collateral prices.

   Challenges I ran into

   Integrations with external services such as payment service providers and Spookyswap.

   Accomplishments that I'm proud of

   Architecting the project with a lot of moving parts and ensuring they all function in synchrony.

   What I learned

   Architecting hybrid permissioned decentralized applications.

   What's next for Azina

   We keep on buidling. Azina has a lot of potential especially in emerging markets where access to the USD is limited.
