What is a crypto wallet?
DefinitionA crypto wallet is an app or device that stores the private keys controlling your cryptocurrency. Your coins stay on the blockchain; the wallet proves they are yours, shows your balance and signs the transactions that move them.
What a crypto wallet actually does
A crypto wallet does not hold coins the way a leather wallet holds cash; it holds the keys that unlock them. If you delete the app, the coins are still on the blockchain, and the recovery phrase brings back access. A typical wallet:
- Creates your private keys, usually from a recovery phrase
- Shows a receiving address for each network
- Reads your balances and history from the blockchain
- Builds and signs transactions so you can send funds
Types of crypto wallets
Crypto wallets are grouped in two ways: who holds the keys, and whether the keys touch the internet. One wallet can belong to both groups at once, such as a self-custody app on your phone, which is non-custodial and hot.
- Custodial: a company holds the keys, as in an exchange account
- Non-custodial (self-custody): you hold the keys and the recovery phrase
- Hot: keys on an internet-connected device, such as a mobile app
- Cold: keys kept offline, such as on a hardware wallet
How to choose a crypto wallet
Before you put money into a wallet, check a few things:
- Does it give you a standard recovery phrase you can restore elsewhere?
- Does it support the networks you actually use, such as Tron for TRC20 USDT?
- Does it show the network fee before you confirm?
- Does it warn you about risky addresses and fake tokens?
- Did you download it from the official website or store?
