Security model

Engineered, not promised.

A breach of Voltrium's servers cannot move your funds, because the servers never hold anything that can. Here is the exact path your key takes — every step runs on your machine.

  1. 01

    Generate

    Your recovery phrase and keys are created locally, from your device's secure randomness.

  2. 02

    Derive

    Your password is stretched with Argon2id (64 MiB) into a vault key an attacker can't brute-force.

  3. 03

    Encrypt

    Keys are sealed with AES-256-GCM — authenticated encryption that also detects tampering.

  4. 04

    Wrap

    The vault is wrapped again with Windows DPAPI, binding it to your Windows user account.

  5. 05

    Store

    The sealed vault stays on this disk. Nothing that can spend your coins ever leaves it.

  • Keys are generated and encrypted on-device — they are never transmitted.
  • Password re-authentication on every send, with a configurable auto-lock.
  • Your recovery phrase is revealed only after you re-enter your password.
  • Contacts in your address book are encrypted before sync — the server sees ciphertext.

Installing

Run the installer and Voltrium sets up your wallet locally on this device. Because the build isn't code-signed yet, Windows SmartScreen may show a notice — choose "More info", then "Run anyway" to continue.

Questions

Straight answers.

What does non-custodial mean?

Voltrium never holds, controls, or can access your private keys or funds. Your keys are generated and encrypted on your own device, and only you can unlock them with your password.

Is my money safe?

Your funds are as safe as the device and password protecting them. Voltrium encrypts your keys locally with Argon2id and AES-256-GCM and never transmits them. There is no account recovery through Voltrium — if you lose both your password and recovery phrase, no one, including us, can recover your funds.

Which coins are supported?

Bitcoin, Ethereum, Solana and Litecoin, along with tokens on those networks.

How do updates work?

Voltrium checks for and installs updates automatically in the background, so you stay on the latest version without reinstalling. Your wallet data is never touched by an update.

Does it cost anything?

Voltrium is free to download and use. You pay only the standard network fees for transactions and swaps, and those are shown before you confirm.

Why does Windows warn about the installer?

The installer isn't code-signed yet, so Windows SmartScreen shows an "unknown publisher" notice. Choose "More info", then "Run anyway" to proceed. Code signing is planned for a future release.
