It simplifies the process of building secure, multichain wallets by leveraging Telegram's cloud storage system to store and retrieve users' private keys.  Problem Addressed: Developers often face challenges when building secure, user-friendly non-custodial wallets. Managing private keys securely, ensuring fast recovery, and integrating multichain support can be complex, especially on mobile platforms.  Key Solutions: Automated Key Management: The SDK automatically generates a master keypair and securely stores it in Telegram’s cloud storage, eliminating the need for external servers or manual key backups. Seamless Wallet Recovery: Users can instantly recover their wallet across sessions by fetching the encrypted master keypair from the cloud. Multichain Support: It simplifies generating keypairs for multiple blockchain networks, streamlining the integration of various chains into a single wallet. By using this SDK, developers can focus on building their dApps while handling secure key management and multichain wallet generation effortlessly inside Telegram.", "hidden": true, "question": "Provide a brief overview of your tool, library, or framework.
