Gasless On-Chain Password Manager: A Comparative Analysis Across EVM-Based Platforms

In the 21st century, with the exponential advancement of the technology industry, most people manage multiple digital identities for diverse online interactions. Safeguarding this plethora of digital IDs necessitates the use of passwords, but the task of remembering them is a hassle of its own. While there exist different types of password managers as solutions, each comes with its own set of advantages and drawbacks. Centralized password managers have a single point of failure, which poses a substantial threat of cyberattacks and security breaches. Additionally, a centralized system requires a form of centralized trust. Conversely, blockchain-based password managers have gas costs and scalability issues. In this paper, we have discussed an architecture to develop a trustless novel gasless on-chain password manager with a robust recovery mechanism. The fundamental goal is to overcome the prevalent challenges related to gas fees in current on-chain password managers, which often impede accessibility and usability. To validate its efficacy, a comparative analysis was conducted across various EVM-compatible platforms, demonstrating the solution’s performance across these platforms.
