FAQ

Common questions

Everything you need to know about cold storage with Qblockx. Can't find your answer?

Ask us directly
What is a cold wallet?
A cold wallet is a cryptocurrency storage method that keeps your private keys completely offline, disconnected from the internet. This creates an air-gapped environment that protects your digital assets from remote hacks, malware, and phishing attacks.
How are my private keys kept offline?
Your keys are generated and stored inside an air-gapped layer that is never connected to the internet. When you move funds, the transaction is signed offline and only the signed result — never the key itself — passes to the online network.
What happens if I lose access to my device?
Qblockx uses encrypted multi-share recovery. Your seed is split into encrypted shares so you can restore your wallet without ever exposing the full seed phrase online. Higher tiers add inheritance and multi-signature recovery options.
Which assets can I store?
Bitcoin, Ethereum and all ERC-20 tokens, plus major networks like Solana, BNB Chain, and Tron. View the full list in the Supported Assets section.
Do you ever have access to my crypto?
No. Qblockx is self-custody — only you hold the keys, and every transfer requires your offline signature. We cannot move, freeze, or access your funds.
How do I get started?
Create a free account, generate your air-gapped cold wallet, and deposit your crypto. Your keys are offline from the very first moment — the entire setup takes under 10 minutes.

Important Notice: Assets held in a Qblockx storage plan are self-custodied: outbound movements require your authorisation, and Qblockx cannot move them without it. Safeguard your recovery shares and credentials — if you lose them there is no support process that can recover those assets for you, and permanent loss is possible. Value you elect to deploy in mining, investments or card-programme products is a separate arrangement with Qblockx as counterparty; the difference is set out in How It Works and in Custody & Security.
