Crypto Wallet Security: Custodial vs Self-Custody Options Uncovered

Setting up a crypto wallet is a crucial step for securing one's digital assets. In Germany, users have two main options: custodial and self-custody models.

In the custodial model, a company holds the private key, providing convenience but also counterparty risk. If the company becomes insolvent or loses control of its keys, funds are tied to that fate.

Self-custody, on the other hand, means the user holds the private key, eliminating counterparty risk but also requiring strict backup procedures. The recovery words are the entire contingency plan.

A software wallet is a practical option for self-custody, generating keys and managing funds within an application. Hardware wallets offer an additional layer of security by storing keys offline on a dedicated device.

The process of setting up a software wallet involves choosing a reputable provider, generating a new wallet, backing up recovery words, and testing the wallet with a small amount. The recovery words are portable between manufacturers and follow an open standard called BIP-39.
