How can Coldbunker products help you manage crypto assets securely? What does it mean to own crypto assets?

Take control of your private keys

Owning crypto assets comes down to managing your private keys. To first receive your assets, you request a transaction to a public address created from your private key. To spend the crypto assets, you digitally sign a transaction using your private key as well.
By using a service that holds your crypto assets, you are putting trust in the service to keep the private keys secure from theft and to send your crypto assets when you request so. As long as you’re not managing your own private keys, you don’t really own your crypto.

Manage your private keys. Securely

Coldbunker wallets enable easy and secure private key management. When you set up your device, a unique set of private keys is created byColdbunker's secure hardware and software. These private keys allow you to manage many accounts and crypto assets from a single device.
You transact by verifying and signing transactions on the device. To withdraw from an exchange, you request your crypto assets to be sent to a public address provided by your Coldbunker wallet. That’s how you become the legitimate owner of your crypto.

Save the recovery phrase, it’s your only backup

When setting up your Coldbunker hardware wallet, it will provide a 24-word recovery phrase, sometimes called (mnemonic) seed, for you to write down carefully. This is the only backup of your private keys. It allows you to restore your private keys if you lose access to your hardware wallet.

When a user first receives their Coldbunker wallet, it must always be initialized by following this process:

  • Powering on the device
  • Generating a pin code
  • Generating 24 words
