Getting started with Cold Storage Coins

Blockchain Mint is the companion app for your physical Cold Storage Coins. It lets you check balances, top up coins, and sweep funds — all without your private keys ever leaving your device.

The app works 100% on your phone: your private keys are never uploaded, never sent to a server, and never stored anywhere else. We only keep a list of your coin addresses (public keys) so we can show balances and send you alerts.

The basics

• Dashboard — see all your coins and their balances at a glance.
• Scan — add a coin by scanning the QR code on your Cold Storage Coin.
• Shop — browse and order new coins.
• Sweep — move funds off a coin by signing the transaction on your device.
• Me — settings, backup, alerts, and this help section.
