Frequently Asked Questions
The cost varies significantly based on complexity. A simple integration of NFTs into an existing game might start around $50,000. A full-fledged P2E game with complex tokenomics and a custom marketplace can range from $150,000 to over $500,000. We provide a detailed, transparent quote after a thorough discovery phase.
The "best" blockchain depends on your specific needs regarding transaction speed, cost, security, and ecosystem. Ethereum with L2 solutions like Polygon or Arbitrum is popular for its security and large user base. Solana offers high speed and low costs. We are chain-agnostic and will help you choose the right platform based on a detailed analysis of your game's requirements.
Security is our top priority. Our process includes: writing code based on industry best practices (like OpenZeppelin standards), conducting multiple internal code reviews, comprehensive unit and integration testing, and performing rigorous security audits and penetration testing before any mainnet deployment. We also recommend and can facilitate third-party audits for maximum assurance.
Absolutely. This is one of our core competencies. We have extensive experience developing SDKs and APIs that connect existing game clients and backends (built in Unity, Unreal, or custom engines) to blockchain networks. We work to ensure the integration is seamless and doesn't disrupt your existing architecture.
While we are not a law firm, we build with compliance in mind and have a strong understanding of the evolving regulatory landscape. We can help you design tokenomics that mitigate securities risks and can connect you with our network of legal partners specializing in cryptocurrency and gaming law to ensure your project is structured correctly from a legal standpoint.
Our approach is data-driven and focused on long-term sustainability. We start by defining the core utility of each token within your game. We then model the flow of value, creating balanced faucets (sources) and sinks (uses) to manage supply and demand. We simulate the economy under stress to ensure it's resilient and designed to reward genuine player engagement over pure speculation.
