Crypto wallet
Definition
A crypto wallet is software or hardware that stores your keys and signs transactions; it does not hold coins, which live on-chain.
A crypto wallet is a tool for managing cryptographic keys. Despite the name, it does not contain any coins. Balances are recorded on the blockchain; the wallet holds the private keys that let you authorise spending and reads the chain to display your balance. When you “send” funds, the wallet builds a transaction and signs it with your key.
Why it matters
Wallets fall into two broad groups. In a self-custody (non-custodial) wallet, you alone hold the keys and the seed phrase, so you bear full responsibility for backups and security. In a custodial wallet, such as an account on an exchange, a company holds the keys on your behalf; you rely on their security and policies. Knowing which type you use tells you who can actually move your funds.
Common misunderstanding
Two ideas cause the most confusion. First, that coins are stored inside the app; they are not, so reinstalling the app does not lose funds as long as you have the seed phrase. Second, that all wallets are equally exposed to the internet. A hot wallet is connected and convenient but more exposed; a hardware wallet keeps keys offline. Choosing between them is a trade-off between convenience and how much value you are protecting. A common pattern is to keep small, active balances in a hot wallet for daily use and larger, long-term holdings in cold storage, so a single compromise cannot reach everything. This layered approach is widely recommended for anyone holding meaningful value.
