Opportuna is a real-time cryptocurrency arbitrage platform that helps traders spot profitable price differences across 12+ exchanges - without needing API keys or coding skills.

What We Do

We monitor live price data across major exchanges including Binance, Bybit, OKX, KuCoin, and more, surfacing two types of arbitrage opportunities:

  • Spot arbitrage: buy crypto cheaper on one exchange, sell higher on another
  • Funding rate arbitrage: profit from spreads between spot and perpetual markets

Key Features

  • Real-time scanner: live price updates, not delayed or historical data
  • Smart filters: filter by exchange, profit threshold, volume, and transferability
  • No API keys required: works out of the box, no complex setup
  • Mobile-optimized: full functionality on any device
  • Free tier: full scanner access with no credit card required
  • Guest preview: browse live opportunities without signing up

Why Opportuna?

Most arbitrage tools either require API keys, limit you to a few exchanges, or show stale data. Opportuna is built for traders who want to find opportunities fast without spending hours configuring tools or manually checking exchanges

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.
