Cryptocurrency Wallets Explained
A wallet helps you manage blockchain assets. Before moving crypto from an exchange, understand who controls the keys and how to match the receiving address, token and network.
What a wallet actually holds
Your assets are recorded on a blockchain. A wallet provides the keys and signing tools used to control an account; it does not contain physical coins. A receiving address can be shared. A private key or recovery phrase must remain secret. An address and a public key are related, but they are not interchangeable.
With self-custody, you are responsible for access and backups. With a custodial exchange account, the provider controls the keys and sets withdrawal rules. An account password is not a blockchain private key. Learn more about public keys.
Hot wallet
A phone, browser or desktop wallet is convenient for regular use. Its signing environment is exposed to an internet-connected device, so phishing, malicious extensions and compromised software matter.
Hardware wallet
A hardware wallet keeps signing keys on a separate device. Verify transaction details on its trusted screen. It cannot protect you from every malicious approval, disclosed recovery phrase or incorrect destination.
Choose the withdrawal network from the destination
Start on the receiving wallet or exchange. Check which network and exact asset it accepts, then choose the same combination on the sending exchange. A matching address format is not proof that the network is correct. Different networks can use addresses that look identical.
| Receiving instructions | Sending choice | Decision |
|---|---|---|
| Token A · Network X | Token A · Network X | Match the address and any memo before sending |
| Token A · Network X | Token A · Network Y | Stop: a cheaper fee does not make this compatible |
| Token A · Network X | Another token · Network X | Stop: the network matches, the asset does not |
Sending on a different network does not automatically bridge your assets. Also check the token contract or asset identifier when the destination requires a particular token version.
A practical withdrawal checklist
- Open the destination’s current receive or deposit screen. Verify the asset and network are supported and deposits are available.
- Copy its address and any required memo or destination tag. Compare the pasted address carefully; do not reuse an address from transaction history without checking it.
- Review the withdrawal fee, minimum deposit and amount that will actually arrive. A test transfer must itself meet the destination’s minimum.
- Send a small test amount, wait for it to be credited, then recheck the details before sending more. A successful test does not make future transfers risk-free.
- For a self-custody wallet, plan for the network’s transaction fee asset if you will later send or use the tokens.
Example: if a fictional exchange deducts a 1-token withdrawal fee from a 10-token transfer, 9 tokens arrive. If the destination minimum is 10, that test is too small. Check how your own exchange calculates the fee.
Sent, but not visible?
Use the transaction ID in the correct network’s blockchain explorer. Check the destination, token and confirmation status. An exchange may need additional confirmations before crediting a completed transaction. A wallet may need the correct network or token display enabled.
If you used an unsupported network or omitted a required memo, contact the receiving service through its official support. Recovery may be impossible. Never give a recovery phrase to someone offering to recover a deposit.
Choose a wallet you can operate safely
Check supported networks, backup methods, device compatibility and the transactions you intend to make. Download software from the official provider, verify the source, and follow its current setup instructions. Keep recovery material offline and separate from the device.
