Open Wallet → Funding, find the asset, click Receive, choose the network and click Get deposit address. Send the coins to this address from your wallet or another exchange.

Open Wallet and choose Funding.
Find the asset (use the search) and click Receive.
In Network choose the network you will send from. Networks marked Suspended do not accept deposits right now.
Click Get deposit address and copy the address or scan the QR code. The address is permanent: you can use it again.
If a Memo (tag) is shown under the address, copy it too: you must send it together with the address.
Check the Min. deposit and the number of network confirmations under the address.
Send the coins. On the sending side choose exactly the same network.

Important:

The deposit is credited to your Funding wallet after the number of network confirmations shown on the Receive page. The time depends on the network and its load. When the deposit is credited, it appears in Wallet → History → Payments with the type Deposit, and you get a notification and an email. Before that the deposit is not shown on the site.

A sub-account gets its own deposit addresses in the same way, signed in as the sub-account; its deposits are credited to its own Funding wallet.

To trade the deposited coins, move them to the Spot wallet: How do I move funds between my accounts?

Deposit not arrived? See Why has my deposit not arrived?

Stay safe: Strade support never asks for your password, 2FA codes or seed phrase. Take the deposit address only from your account page, never from an email or a message.
