Transferring SOL (Solana) from Binance to OKX (formerly OKEx) is a straightforward process, but it requires careful attention to network selection and wallet addresses. This guide explains exactly how to move your SOL tokens between these two major exchanges.

First, log into your Binance account and navigate to the "Withdraw" section. You can find this under the "Wallet" tab. Select SOL as the cryptocurrency you want to withdraw. If you have multiple assets, make sure you choose SOL specifically, not any other token on the Solana network.

Now you need to get your deposit address from OKX. Log into your OKX account, go to "Assets" then "Deposit". Search for SOL. The exchange will display a deposit address and require you to select the correct network. This is the most critical step: you must choose the Solana network (not BEP-20, not ERC-20, not any other chain). If you select the wrong network, your funds may be lost permanently.

Copy the OKX SOL deposit address. Return to Binance and paste this address into the recipient field. Binance will typically automatically suggest the correct network. Confirm it says "SOL" or "Solana" network. Do not proceed if it shows a different network like BSC or Ethereum.

Enter the amount of SOL you want to transfer. Pay attention to the minimum withdrawal amount set by Binance and the withdrawal fee. For SOL transfers, the fee is usually a very small fraction of a SOL token. Larger withdrawal amounts sometimes have lower relative fees.

Review all details: the address, the network, and the amount. Binance will prompt you to confirm via email or 2FA. Complete the security verification. The withdrawal will be submitted and you will see a transaction ID (TXID).

SOL transfers on the Solana network are very fast, typically completing in 10-30 seconds. Do not close the page or refresh aggressively. Wait for the transaction to show as confirmed on the blockchain.

Check your OKX account. Go to "Assets" then "Deposit History" or "Transaction History". The SOL should arrive within a minute or two. If you see the transaction as successful on Binance but not yet in OKX, wait a few minutes. The OKX system may need a moment to process the incoming transfer.

Common mistakes include using the wrong network (e.g., sending via BEP-20 when OKX expects Solana), entering an incorrect address by one character, or forgetting the memo/tag. For SOL transfers, no memo is required, but always double-check the address you pasted.

If your transfer does not arrive after 30 minutes and the Binance history shows a "Completed" status, contact OKX support. Provide them with the transaction hash (TXID) from Binance. They can check the blockchain and credit your account if the network and address were correct.

For frequent transfers between Binance and OKX, consider whitelisting your OKX deposit address on Binance. This adds a security layer and can speed up future withdrawals because you will not need to approve a new address each time.

By following these steps carefully, you can move SOL between Binance and OKX safely and efficiently. Always triple-check the network before confirming any cryptocurrency transfer.
