About
SUMaillet is a secure, self-custodial browser mailbox built for SUM Chain. It lets you create and manage your blockchain identity, sign transactions, and authenticate with decentralized applications, all directly from your browser. Your private keys are encrypted and stored locally on your device. They are never transmitted to any server. Features: - Create a new wallet with a standard BIP39 mnemonic seed phrase - Import an existing wallet using your recovery phrase - Sign transactions and messages requested by SUM Chain dApps - Seamless in-page authentication via browser integration - Auto-lock after a period of inactivity to protect your wallet - No account registration or personal data collection required - SUMaillet connects only to SUM Chain endpoints to broadcast signed transactions. It does not collect analytics, track browsing activity, or share any data with third parties. Permissions explained: - Storage: Used to save your encrypted wallet data locally - Alarms: Used for the auto-lock timer to secure your wallet when idle
