Hi @MSghais i will like to take this up
Kindly assign

Hi @ShantelPeters!
Maintainers during the ODHack # 8.0 will be tracking applications via OnlyDust.
Therefore, in order for you to have a chance at being assigned to this issue, please apply directly here, or else your application may not be considered.

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

software engineer(backend) and contributor in similar project from last hacthons(https://app.onlydust.com/u/Josh-121). looking to make first contribution here

How I plan on tackling this issue

Set Up Database Models
Review Vault Repo: Analyze the existing database models in the Vault repository under the src/routes directory to understand how data is structured.
Define Models for Onramp/Offramp: Create new database models for the onramp/offramp process. This should include fields such as:
Nostr Pubkey/Starknet Address: For user identification.
Passkey (if applicable): As an alternative to Starknet or Nostr keys.
Transaction Data: Include fields for tracking transaction status (e.g., pending, completed, failed), timestamps, and any metadata related to the onramp/offramp process.
Migration Scripts: Write database migration scripts to add these models to the existing schema.
2. FunKit SDK Integration
Install FunKit SDK: Integrate the FunKit SDK into the backend. Ensure all necessary SDK functions for Starknet onramp/offramp are imported.
Handle Onramp/Offramp Logic: Write service functions using the FunKit SDK to handle:
Onramp: Depositing assets from external sources to Starknet.
Offramp: Withdrawing assets from Starknet to external sources.
Ensure proper error handling and logging for potential issues in the onramp/offramp process.
3. Create Backend Routes & Endpoints
Write New API Endpoints:
Onramp Endpoint: Allow users to initiate an onramp transaction by sending their Nostr pubkey/Starknet address and relevant onramp data.
Offramp Endpoint: Allow users to initiate an offramp transaction similarly.
Read/Write to Database: Ensure these routes can both log transactions (write) and query their status (read) by interacting with the database models.
Security & Validation: Implement necessary validation for Starknet addresses, Nostr pubkeys, and Passkeys. Add security measures such as rate limiting and input sanitization to avoid abuse.
4. Testing and Validation
Unit Testing: Write tests for the new models, service functions, and API routes. Mock the FunKit SDK calls to simulate successful and failed transactions.
Integration Testing: Test the end-to-end flow for both onramp and offramp to ensure data is correctly written to the database and transactions complete without errors.

My background and how it can be leveraged

Hello @ @MSghais please kindly assigned as discussed.

ETA: 2 days

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I have experience in developing backend systems and integrating various SDKs, including FunKit, which aligns with the requirements for adding onramp/offramp functionality for Starknet. My familiarity with database modeling and API route implementation will enable me to efficiently create the necessary models and endpoints. Additionally, I have a strong understanding of React Native, which will be beneficial if UI integration is pursued in a future task.

How I plan on tackling this issue

Review existing code for insights into database models and structure.
Create database models for onramp/offramp.
Integrate Funkit SDK for transactions.
Develop routes and endpoints for handling requests.
Test functionality thoroughly.

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I have a solid background in backend development and database management, with experience in integrating APIs and SDKs

How I plan on tackling this issue

To implement this, I would:

Examine the Vault repo to understand the current database models and backend structure.

Create new database models for onramp/offramp functionality that include Nostr pubkey, Starknet address, or Passkey.

Set up the Funkit SDK in the backend to handle onramp/offramp transactions.

Create the necessary routes and endpoints for reading and writing data related to onramp/offramp operations.

Implement unit and integration tests to ensure functionality and reliability.

If needed, outline a plan for simple UI integration in the React Native app for user interaction.
