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 showing transaction details and the requesting origin.

Features:

Password-protected encrypted vault (AES-256-GCM, PBKDF2-SHA512, 600,000 iterations)
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, Ethereum, and cross-chain intents
EIP-191 and EIP-712 message signing
Multi-chain address derivation (Ethereum, Solana, Cosmos, Aptos, Sui, TRON, TON, NEAR)
Auto-lock after 15 minutes of inactivity
No analytics, no telemetry, no data collection

Integrates with the Certen Protocol web application via the window.certen provider API.

Is Certen Key Vault Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Certen Key Vault requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Certen Key Vault may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
