Expected duration: 1 - 6 months Description: We are building a platform with secure, token-based reward mechanics. The web UI has been fully designed and visually prototyped, giving you a clear foundation while leaving room for integration and modifications to support blockchain-based reward logic and session data.
Responsibilities: - Design and implement smart contracts for token-based rewards. - Ensure secure, accurate transactions and token distribution. - Collaborate with the web team to integrate blockchain rewards with the visually prototyped UI, including implementing state management and API interactions. - Test, debug, and optimize smart contracts for performance and security.
Requirements: - Experience with Ethereum, Solana, Polygon, or similar blockchains. - Strong understanding of smart contracts, token standards (ERC-20/ERC-721), and secure transaction handling. - Experience integrating blockchain solutions with web applications. - Ability to work independently and communicate clearly with a remote team.
Preferred: - Previous experience with play-to-earn or token reward platforms. - Knowledge of web frameworks (React, Vue, Angular) for integration.
