ProprietaryX

ProprietaryX turns the prop-firm trading model into an on-chain workflow for Arbitrum. A trader starts by buying an examination account on Arbitrum Sepolia using Circle Test USDC. The account receives a paper balance, trades against real-time GMX-derived market data, and is evaluated through contract-enforced risk rules. The trader can also authorize an agent signer, allowing an AI trading agent to place exam trades through the same account permission system as a human wallet.

The examination layer is built to feel like a real trading environment without risking platform capital during evaluation. It uses live GMX market data with an off-chain paper execution and order-matching layer for the exam experience, while the contract system records account ownership, signer permissions, ledger activity, rule checks, PnL, drawdown, and pass/fail state. This gives users a fast and realistic examination flow while keeping the account state and risk logic auditable on-chain.

Once a trader passes the examination, ProprietaryX activates a funded account. The funded trading terminal is the real-capital path designed around GMX execution on Arbitrum. For this hackathon build, the contracts already support the funded account lifecycle, order records, reconciliation states, and 85/15 payout accounting between the trader and the platform. Live GMX keeper execution is being treated honestly as the next production milestone; the current funded demo can run in fallback mode to prove the contract lifecycle without overstating live keeper fills.

During the hackathon, I built ProprietaryX as a full-stack Arbitrum application. I wrote and deployed the core smart contracts: AccountRegistry, RuleEngine, GmxOracleAdapter, ExaminationVault, FundedVault, and PayoutVault. Together, these contracts handle account creation, signer authorization, risk rules, exam trading, pass/fail resolution, funded account activation, funded order status, and payout accounting.

I also built the frontend application in Next.js. The app includes a landing page, wallet connection, challenge selection, Circle Test USDC approval and purchase flow, examination terminal, funded trading terminal, rule and drawdown displays, account state views, and deployment proof. The frontend supports both a demo mode and a real testnet mode that reads from and writes to deployed Arbitrum Sepolia contracts.

On the backend, I built a TypeScript agent service. It supports the prop-firm demo state machine, GMX market and price helpers, trade previews, funded-account flows, payout routes, admin demo controls, and a BYOK agent decision endpoint. The agent endpoint lets a user connect their own OpenAI key and ask the agent to propose a trade intent based on the account and market context.

I also added smoke scripts, deployment scripts, GMX validation, test coverage, and submission documentation. The repo includes Foundry tests for exam purchase, signer authorization, risk rejection, PnL, drawdown, funded activation, funded order lifecycle, and 85/15 payouts. We validated GMX Sepolia addresses and market reads, while keeping the live keeper-fill limitation clearly documented.

ProprietaryX does not currently have any formal fundraising status. We have not raised outside capital, announced a round, or accepted committed investment for this project.

That said, the project was built with a clear path beyond the hackathon. Our goal is to keep scaling ProprietaryX from a testnet proof-of-concept into a mainnet-ready agentic prop firm on Arbitrum.
