# API Wallet The wallet system is the cornerstone of play-to-earn games, but some native mechanism of blockchain may cause a worse user experience. Issues such as unfriendly gas fee mechanism, complicated multi-chain assets management, and cumbersome interaction steps still need to be optimized. To make building a GameFi wallet system easier, Rollin.Games provides multiple ready-to-go APIs for creating a ZERO-entry-barriers wallet system for developers. Which significantly lowers the barrier for both developers and players to enter GameFi. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
