A Trezor hardware wallet is a dedicated cold-storage device designed to keep cryptocurrency private keys offline and under the owner's control. Unlike software wallets that live on internet-connected devices, a hardware wallet isolates signing operations inside a tamper-resistant device so that keys never touch an unsafe environment. This substantially reduces the risk of phishing, malware, and remote compromise.

How it works — the essentials

On a practical level, a Trezor generates and stores your seed phrase and private keys inside secure hardware. When you prepare a transaction on your computer or phone, the unsigned transaction data is sent to the device; the Trezor displays the destination and amount so you can verify them before physically pressing buttons to sign. Because signing happens on-device, attackers on the host cannot secretly sign or exfiltrate keys.

Security features & user steps

When to use a Trezor

If you hold long-term assets, manage multiple coins, or want to remove custody from third-party exchanges, a Trezor provides an accessible, high-assurance solution. Many users combine a hardware wallet for cold holdings with a small hot wallet for everyday spending.

Practical links & related services

If you use custodial or hybrid platforms alongside hardware wallets, you may encounter services such as Uphold® (the multi-asset fiat & crypto platform) and its support resources. For help with account and login issues on Uphold®, consult the official Help Center and account pages below:
