Smart Contract Engineer (NFT Marketplace) About the Project We are developing a next-generation decentralized marketplace designed to return data sovereignty to users and eliminate reliance on centralized intermediaries. Our platform leverages high-performance blockchain logic, decentralized storage, and advanced encryption to create a secure environment for verifiable digital assets. By moving away from centralized databases, we enable true ownership, private encrypted access, and the creation of composable reputation data within digital ecosystems. Responsibilities Contract Development: Design and deploy robust smart contracts managing asset lifecycles and secure state transitions. Storage Integration: Architect systems linking on-chain assets to high-capacity decentralized storage to ensure data integrity. Privacy & Security: Implement encryption protocols to secure sensitive metadata, ensuring only authorized holders gain access. Onboarding & UX: Integrate modern authentication, including social-login flows, to simplify the user experience for mainstream audiences. Optimization: Refine transaction logic and batching to maintain high throughput and reduce operational costs. Technical Stack Language: Move Blockchain: Sui Network Storage: Walrus Protocol Encryption: Seal Identity: zkLogin Experience Required Smart Contract Expertise: Proven experience with object-centric or resource-oriented blockchain environments. Infrastructure: Proficiency in integrating decentralized storage solutions and managing content-addressed data. Cryptography: Technical experience with threshold encryption, verifiable credentials, or zero-knowledge proof systems. Logic Design: Deep understanding of secure fund-handling, programmable escrow, and capability-based security models.
