In plain English
What Crypto wallet means
A wallet does not usually “store coins” the way a bank account stores money. Instead, it stores or helps manage the cryptographic keys that control blockchain addresses. Some wallets are software apps, some are hardware devices, and some are services run by a third party. Control of the keys matters because it determines who can authorize transfers.
Why it matters
The wallet model affects security, recovery, and who can move the assets. In self-custody setups, losing the keys can mean losing access. In custodial setups, a provider controls the keys and the customer depends on that provider’s systems, policies, and solvency.
Example
A user installs a mobile wallet, creates an address, and receives bitcoin. Later, they use the wallet to sign a transaction that sends a portion of that bitcoin to another address. The blockchain transfer is recorded on-chain; the wallet is the interface that authorized it.
