Implementing the frontend for a smart contract, especially one as complex and feature-rich as Ajna, requires a systematic approach that accommodates its unique attributes. Here’s a high-level overview of how to approach this:

1. Understand the smart contract functions: We developed a deep understanding of the smart contract’s functions and events. This includes understanding how the lending protocol operates without oracles, how it maintains immutability, and the incentive mechanisms it uses.

2. Create Web3 Provider: Utilisation of ethers.js library to interact with the Ethereum blockchain.

3. User Authentication: Integration of the wallet provider.

4. Smart Contract Interaction: Build interfaces that allow users to execute smart contract functions such as lending, borrowing, managing their positions, take part in liquidation auctions and participate in protocol voting and grants. This involves aggregating data from multiple sources, parsing blockchain state, sending transactions and handling confirmations.

5. Event Handling and State Management: Listen for contract events and state to update the UI in real-time. Use async state management libraries like react-query, Apollo and React Context API to manage application state across different components and data sources.

6. Error Handling and Transactions: Implementation of comprehensive error handling to deal with failed transactions or rejected promises, which can occur due to the immutability of the contract or other reasons.

7. UI/UX Design: Design a user-friendly interface that abstracts the complexity of the blockchain. The UI presents information clearly and guide users through each interaction step by step.

8. Testing: Rigorously test the frontend with unit tests, integration tests, and end-to-end tests.

9. Security: Since the protocol is permissionless and aims to be censorship-resistant, security is paramount. Security audits were conducted and incorporate best practices to protect users’ funds and data implemented.

10. Handling Immutability: To avoid issues during redeployment, the frontend handles updates or migrations of the smart contract without significant downtime or user friction.

11. Documentation and Support: Detailed documentation and support channels for users to understand how to interact with the dApp and troubleshoot issues was provided.

12. Responsive Design: Frontend is responsive and accessible across different devices and platforms to reach a wide user base.
