Want to transfer coins from the exchange to your Web3 wallet, or vice versa? This tutorial will guide you step by step. The prerequisite is that you have already created a wallet and have a basic understanding of concepts like public chains, GAS fees, and main chain coins.

**Deposit Process (Exchange → Wallet)**

Step 1: Open your wallet and find the receive entry point (usually there are two), then click in.

Step 2: Select "Transfer from Exchange," then choose the coin type. Taking BNB as an example, then select the public chain — here we use Binance Smart Chain (BSC) for demonstration. **Note: No matter which chain you are transferring to, you must first transfer a small amount of the main chain coin as GAS fee.** For example, on BSC, you need to transfer some BNB as a fee, so that when transferring tokens like USDT later, you won't be prompted about insufficient fees; for SOL chain, transfer SOL; for Ethereum, transfer ETH, the logic is the same.

Step 3: Enter the amount of BNB to transfer, then click Next.

Step 4: Confirm again + complete security verification, usually arrives almost instantly.

Step 5: Check the transaction record in your wallet to confirm the deposit has arrived. Then switch back to the exchange, click Assets → Spot, find the BNB record to verify the transfer out was successful — in this case, we are transferring from the spot account, which is the usual operation.

That's it. The reverse operation (transferring from wallet back to exchange) is similar in logic, more details will be explained later.
