Hi there 👋, kox here

Welcome to my PoW ! I'm a passionate developer focused on building and contributing to the Solana ecosystem. Below, you'll find a collection of projects I've worked during last months related with Turbin3, with a focus on the Q3 Cohort.

I also included my participation in the Talent Olympics during the 4 days in which I earned a bronze medal.

Please, don't hesitate to drop some comments, open issues, follow or contribute.

Capstone

Introduction

My capstone project aims to create a platform that allows users to deploy customizable vaults on Solana. The platform is designed to start with simple vault structures that can be tailored to meet various needs and strategies.

Goal

The primary objective is to offer a flexible platform for building and managing vaults, while also providing tools for options, analytics, and strategy development.

The platform will integrate Solana Blinks for facilitating the customer acquisition.

Technology Stack

• Blockchain: Solana
• Smart Contracts: Anchor
• Customer Acquisition: Solana Blinks
• Frontend: React
• Backend: Fastify

The roadmap is pretty extensive so I hope to keep it simple and see where it takes me.
