Delivery

Primary Mint

We engineered the NFT contract architecture with dynamic pricing that increases on every mint, creating built-in scarcity mechanics.

The mint flow was optimized for Immutable zkEVM and integrated with Immutable Passport for seamless wallet onboarding.

Marketplace Infrastructure

We designed and implemented both primary and secondary marketplace logic, enabling secure peer-to-peer trading directly within the ecosystem.

The system supports structured listing, settlement, and asset transfers, tightly integrated with the NFT contracts to ensure ownership, pricing, and trading operate cohesively.

Leaderboard & Game Integration

We built the API bridge between smart contracts and the game engine, enabling real-time synchronization of NFT ownership and in-game inventory.Leaderboard logic was implemented to reflect player activity and performance, connecting blockchain assets with competitive gameplay mechanics in a unified architecture.

Outcome

OverKnights launched with a scalable Web3 architecture enabling dynamic minting, frictionless onboarding, real-time asset synchronization, and integrated marketplace trading.

The result is a production-grade gaming infrastructure where NFTs, player inventory, and competitive mechanics operate as one cohesive system.
