Scalable Token Staking and Reward Distribution on Ethereum: A Pull-Based Smart Contract Approach

Abstract: Traditional financial systems commonly suffer from central control, opacity, and exclusion. Decentralized Finance (DeFi) solves this by employing blockchain technology such that users can interact directly without the need for intermediaries. Nonetheless, developing secure, equitable, and user-friendly staking systems is an enormous challenge. This paper introduces a DeFi token staking and rewards management automation platform based on Ethereum-based programmable contracts, React, and Node.js. By removing third-party control and offering transparent protocols, the system enables users to stake tokens securely. Smart contracts handle significant aspects such as the lock-up period, penalties, and reward distribution. With MetaMask support, authentication and transaction processing are seamless. A new dynamic reward mechanism optimizes payouts based on staking duration and network activity, promoting equitable rewards for small players. With OpenZeppelin for comprehensive audits, the platform provides increased security and reliability with a 40% reduction in gas fees compared to traditional models.Democratized passive income access and centralization risk elimination, this work facilitates the creation of scalable, user-centric DeFi applications. It offers a blueprint for the wider adoption of decentralized financial infrastructures, driving the creation of open and inclusive economic systems.
