Crypto Startup MVP in 30 Days – DAY 9/30
Laid the foundation for the crypto project frontend. First lines of code today! 
Set up the architecture
Crypto startup MVP in 30 days – DAY 9/30
Today I mainly focused on the UX of the form and the project overall, quickly designed the app and created the form, as well as made a mobile version. Everything is now ready in the Next.js application for further integration.
I also added a store using Zustand — it’s lightweight, simple to use, and offers efficient state management with minimal boilerplate, making it perfect for fast iteration and scaling in React apps.
The AI Vibe Trader interface is live.
Next up: GMX integration, followed by a clean, intuitive TradingView-powered chart designed for everyday users — no noise, just clarity.
I’ve already done a deep dive into GMX, but the next 10 days will be all about mastering the internals — reverse engineering, refining, and building a custom implementation tailored to our product vision.
We’re not just shipping features — we’re laying the foundation for a user-first trading experience.
First trade is live!
Today I successfully executed the first trade from my own interface directly into the GMX smart contracts — and it felt great.
I’ve also started integrating the custom trading form — still a work in progress, but we’re moving fast toward a seamless user-driven trading flow.
But this trade is on Arb real GMX contracts, my next aim is to make short and close position and make a Arb contracts => make a Hyperion contracts
Today’s focus: connecting the frontend to GMX smart contracts.
The goal is to fully wire up the custom trading form — sending user input directly into the contract — and implement market close for long positions.
Step by step, we’re turning this into a real trading product.
This weekend, I hit pause on the project.
I was mentally drained — too much coding, research, context-switching.
Sometimes the fastest way forward is to step back.
I took a break, got some rest, spent time offline. And honestly, it helped a lot.
Today I’m back — focused, recharged, and ready to push hard again.
Today I spent time diving into GMX’s smart contracts. There are some solid mechanisms in place, but I’m not sure all of them are necessary for the MVP.
This week, the goal is to finalize the research and get the contracts live.
Right now, I’m leaning toward a minimal setup: just two contracts — Vault and PositionsManager. Simple enough for an MVP, but structured to scale later.
Today I did a base for a contract for DogEx and tested it!
Under the hood — how DogEx works
Vault enables DOGE/USDC leveraged trading through a minimal interface:
openPosition() — Enter long/short with leverage (10x–100x)closePosition() — Settle P&L, reclaim collateralCollateral: USDC
Leverage: 10x–100x
P&L logic: Calculated on-chain
Security: ReentrancyGuard, owner-controlled pricing with safeguards
Manual price feed for now — capped at ±10% per update with 1-minute cooldowns.
All critical actions emit events: position openings/closings, price updates — enabling full frontend and analytics support.
Today we’re laying the foundation for our own price oracle — a critical piece of infrastructure for any serious DeFi protocol.
I’m deploying a minimal, chain-agnostic oracle prototype on Sepolia. The architecture is lean and pragmatic:
getPrice()setPrice()This setup gives us reliable, on-chain access to external pricing — essential for use cases like a futures exchange. No price, no protocol. We’re solving that today.
Execution over complexity.
Ok now I have 3 parts for my mvp: oracle, contract and frontend. On this stage I want to merge all of them and see how it works on Arbitrum and then move to Hyperion
It almost works on sepolia rn. My plan for now
@i_am_supaman_lj where are you?
Nice project, I think the gamification put you out of touch with your real goal. You should stick to one niche or trend. DEX or gamefi.
You have a great DEX project but not a god gamefi project.
Not all project have to do everything, just solve a problem. Just a token from me.
This is where I got to from following the link sent.
Now my main aim to move it to Hyperion chain, show to first users and work on improving MVP experience
Done now, thanks for the insight
You are welcome, any other thing you need you can tag myself or @Ghostt
Today I deployed all contracts to Hyperion testnet.
DogEx
oracle with $DOGE price
liquidator
Just waiting for more gas from the @hyperion_xyz to launch it!
DogEx is LIVE on Metis Testnet!
