Our Work - Engineering the future of digital infrastructure.

RaffleKing pairs a skill question on every entry with provably fair randomization on Ethereum, so only eligible participants who answer correctly enter the draw — and anyone can reason about outcomes using on-chain verification rather than trusting a black-box server.

The platform supports multiple ticket economics: standard paid entries, bonus tickets from promotions and loyalty, and occasional free-entry mechanics, so acquisition and gameplay can evolve without splitting the core raffle engine.

For day-to-day play, ERC-7702 lets the platform sponsor transactions from per-user platform wallets so players get a seamless flow without signing every chain action — a better fit for web2-native users who expect one-click, app-like UX.

Toshi Labs led the development organization end-to-end and built the Mainnet smart contracts for fair draws, ticket accounting across categories, automatic prize distribution, and the ERC-7702–based sponsorship path integrated with those flows.

Certenticat revolutionizes product authentication by combining NTAG242 NFC chip technology with blockchain immutability, creating an unclonable digital identity for physical products that enables instant verification and ownership tracking.

We developed the complete authentication infrastructure including NFC chip integration, blockchain smart contracts for immutable record-keeping, mobile SDK for seamless scanning, and a comprehensive web platform for partners to manage their authenticated products.

Drunken Monkey Members Club revolutionizes luxury concierge services through 5,995 unique NFTs on Ethereum, offering lifetime access to exclusive dining, travel, and VIP experiences without recurring fees.

We built the entire web application, developed smart contracts for NFT minting and membership verification, and led technical oversight of the mobile app development to create a seamless luxury experience platform.

Interview AC revolutionizes technical interview preparation with a course-driven approach, offering structured learning paths, thousands of coding problems, and an advanced Monaco-based code editor with real-time execution.

We built the entire platform from scratch using Next.js, implementing a robust code execution system with time and memory limits, Markdown-based content publishing, and a sophisticated Monaco editor integration for a seamless coding experience.
