What is a crypto wallet?
TradFi equivalentCloser to a keyring than to a bank account. A bank account is a claim on the bank's balance sheet, while a wallet holds only the credential proving control of assets that sit on a public ledger.
The definition above says a wallet holds keys rather than tokens. What it leaves out is the work the software does with them. A wallet derives addresses from a seed phrase, reads balances from an RPC endpoint, builds transactions, asks the holder to approve them, signs with the private key and broadcasts the result. Each of those steps is a point where what the holder sees and what actually gets signed can diverge.
Wallets also differ in what controls the address. A standard wallet signs for an externally owned account, where one key carries full authority. A smart account built on account abstraction puts a contract in charge, which makes spending limits, multiple signers and social recovery possible.
The bank account analogy holds only on the interface: both present a balance and a way to send funds. It breaks on everything behind that. A bank account is a claim on an institution that can freeze, reverse or restore it. A wallet is a credential, and nobody stands behind it.
The decision a holder faces is which signing setup matches the value at stake: a hot wallet for operating balances, a hardware wallet or multisig for reserves, and a recovery path settled before it is needed.
