Sending SOL or any other SPL tokens to a Centralized Exchange (CEX) is, in general, as simple as sending SOL to other Solana Wallets.
Usually, the process goes like this:
1. Find SOL or a supported SPL token on your CEX (centralized exchange) portfolio, this may vary from exchange to exchange. If you’re unsure of how to obtain it, we encourage you to get in touch with your CEX’s support team.
2. Find the receive button, which will give you an address you must copy.
Protip: Solana addresses are usually up to 44 characters long, and don’t begin with “0x…”
3. Navigate to your Solflare wallet’s portfolio and find the Send button, and paste the address you got from the exchange.
4. Check the SOL/ SPL token account on your centralized exchange’s wallet balance.
Note: as we explained in our lost assets article, some centralized exchanges do not support all SPL tokens, so it might be in your best interest to only send SOL if you’re unsure. Sending other SPL tokens to a SOL address may result in funds loss.
