Work through the essentials
Use these checks alongside your own device, network, and transaction context. This guidance does not perform wallet operations.
Know what stays offline
Cold-storage principles aim to reduce exposure of signing keys, not to move blockchain assets off-chain.
Understand the signature step
Transactions still need approval and broadcast; know which device handles each step.
Protect physical materials
Offline devices and backup records can still be lost, damaged, or stolen.
