Powered by a sophisticated risk engine with dynamic withdrawal limits, tiered liquidation, backstop community fund, auto‑deleveraging, and real‑time risk monitoring. The platform also aims to democratize MEV. - **[HelloTrade (mobile app)]**: A mobile‑first, blockchain‑powered trading app (not yet launched publicly; expected end‑2025 / early‑2026) that enables users to trade U.S. stocks, commodities, ETFs, and cryptocurrencies in a single interface, using crypto rails to bypass traditional brokerage barriers. ## Market Standing - **Valuation**: Not disclosed (seed stage) - **Key Metric**: Total seed funding raised – **$4.6 million** - **Notable Investors/Partners**: Lead investor: Dragonfly Capital. Also backed by Mirana Ventures and multiple angel investors. - **Growth Signals**: - Founders previously led BlackRock’s pivot into crypto (iShares Bitcoin Trust, Ethereum Trust ETFs). - Pre‑launch, already hiring founding‑level engineers (smart contract, low‑latency Rust/C++ roles). - Target market: global investors who lack access to U.S. equities (e.g., Vietnam, Indonesia), a large underserved demographic. ## Competitive Advantages - **Founder DNA**: Both founders came from BlackRock’s digital assets team, bringing deep institutional knowledge of compliance, trust, and large‑scale trading infrastructure. - **Blockchain‑native architecture**: By tokenizing traditional assets, HelloTrade enables 24/7 trading, fractional ownership, and global access without traditional intermediaries. - **Mobile‑first UX**: Purpose‑built to be more intuitive than incumbents like Robinhood or Revolut, with a focus on clean user interface and seamless on‑chain transactions. - **DeFi risk engine**: Perpetuity’s sophisticated risk management system (dynamic limits, tiered liquidation, community fund) differentiates it from simpler DeFi exchanges. ## Strategic Focus - Launch the HelloTrade consumer app globally by early 2026. - Invest heavily in security and user education to build trust with new users unfamiliar with blockchain. - Continue building out the Perpetuity protocol as a capital‑efficient, secure venue for perpetual futures and leveraged trading. - Grow engineering team (currently ~4–10 employees) in New York, with hybrid presence. ## Why Work Here - **Culture**: Fast‑paced, mission‑driven team of builders from BlackRock, top crypto firms, and high‑growth startups. Hybrid work model with in‑person preference in New York. - **Engineering focus**: Early team members get meaningful equity and autonomy to architect core systems (matching engine, smart contracts, risk models) from scratch. - **Perks**: Competitive salary, unlimited PTO, flexible hours, health/dental/vision benefits. - **Impact**: Solve cutting‑edge problems at the intersection of crypto, global markets, and mobile UX – a rare chance to build a new financial primitive. - **Work environment**: Small team (pre‑launch), high ownership, direct lines to founders. ## Sources 1.
