Wallet basics

Digital wallets can present payment cards, display a provider balance, or authorize blockchain transactions. Start by identifying the product you are evaluating and what the balance represents. Then compare who holds the keys, how access is recovered, and which networks and devices are supported. These guides turn unfamiliar terms into practical questions you can use when reviewing a wallet. Read the introduction first if the terminology is new, then use the custody and hot-versus-cold comparisons to separate control from the signing environment. Finish with the selection guide to build a requirement list around an actual task instead of choosing by features you may never need.
