Sportsbetting Dark Pool

About project

Sportsbetting Dark Pool is an exchange platform for bookmakers, including betting shops, syndicates or hedge funds with cryptocurrency payments. The exchange algorithm works P2P, which assumes no single central counterparty on which all bets are kept. All bets are absolutely secure and anonymous, and even the company staff does not know who is betting on the game.

Facts

First anonymous bet exchange with payment in crypto.

Implementation

Idea (April 2022)

The customer approached us with a problem but no clear vision for the solution—no defined technology stack, user experience, or understanding of blockchains and cryptocurrencies.

Through multiple brainstorming sessions, we developed a concept that included:
- A component and infrastructure scheme.
- A general algorithm for core processes.
- A structured data model ensuring the required level of anonymity.


Proof of Concept (August 2022)

  • Developed a fully functional prototype covering key business processes, including secure anonymous authentication, balance management (deposit/withdrawal, transaction adjustments), P2P matching, reporting, administration, and public blockchain interaction.
  • Integrated third-party services to fetch game feeds, results, and other critical data for deal execution.
  • Deployed Smart Contract v1 on the production Ethereum blockchain.
MVP (December 2022)

  • Optimized system performance for mobile devices, ensuring smooth operation within the MetaMask browser on Android and iOS.
  • Enhanced user experience and core functionality based on early client feedback.
  • Implemented an incident reporting system via Skype.
  • Improved overall system performance by 10x.
Soft Launch (January 2023)

  • Completed a third-party security audit, including source code review, smart contract analysis, and penetration testing.
  • Prepared the system for a soft launch.
Developed Functionality

  • Peer-to-peer anonymous matching algorithm.
  • Ethereum-based smart contract for balance storage and transaction settlement.
  • Secure anonymous authentication via crypto wallet (MetaMask integration).
  • Cross-platform support for mobile and desktop applications.
  • Client-side blockchain node ensuring full anonymity and operational independence.
