Wallets, Keys & Self-Custody

Owning digital assets is one thing. Controlling them safely is another. Wallets, Keys & Self-Custody explains how wallets, addresses, private keys, recovery phrases and transaction signing actually work, and why operational discipline matters as much as technology. The book compares custodial and self-custodial models, explains hot wallets and hardware wallets, and shows how to build a practical recovery and backup strategy. Readers will also learn how common security failures occur, how to reduce single points of failure, and how to design a personal custody plan appropriate to their own level of responsibility. The objective is not to encourage self-custody at all costs. It is to ensure that readers understand the responsibilities involved before taking control.
