About

Certen Key Vault is a secure browser extension for managing cryptographic keys and signing blockchain transactions across Accumulate and EVM networks.

Your private keys are encrypted with AES-256-GCM and never leave your browser. Every signing request requires your explicit approval through a visual popup that shows transaction details and the requesting origin.

Key Features:
- Password-protected encrypted vault (AES-256-GCM, PBKDF2-SHA512)
- Ed25519, secp256k1, and BLS12-381 key generation
- BIP-39 mnemonic seed phrase backup and recovery
- HD wallet with BIP-44/SLIP-0010 key derivation
- Transaction signing for Accumulate cross-chain intents
- Multi-chain address derivation for popular networks
- Auto-lock after 15 minutes of inactivity
- No analytics, no telemetry, no data collection

Certen Key Vault integrates with the Certen Protocol web application via the window.certen provider API, enabling two-phase transaction signing with user-controlled approval.
