Overview

Secure key vault and signer for the Certen Protocol - generates, stores, and signs with ED25519 and secp256k1 keys

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.
