The Lightning Network is revolutionizing how users deposit and withdraw Bitcoin by offering faster, low-cost transactions. As a second-layer solution built on top of the Bitcoin blockchain, it enables near-instant transfers with minimal fees—making it ideal for microtransactions and frequent traders. On OKX, you can leverage the Lightning Network for BTC deposits and withdrawals, with a per-transaction limit of up to 0.05 BTC and a daily cap of 0.5 BTC per user.
This guide walks you through everything you need to know about using the Lightning Network on OKX—from its benefits to step-by-step deposit instructions for both web and mobile platforms.
Why Use the Lightning Network for BTC Transactions?
Bitcoin’s base layer has limitations: slow confirmation times and high fees during peak congestion. The Lightning Network addresses these pain points by enabling off-chain transactions that settle instantly and cost fractions of a cent.
Key Advantages of the Lightning Network
- High Transaction Speeds (TPS): While Bitcoin’s main chain processes around 7 transactions per second (TPS), the Lightning Network supports thousands of TPS—scalable to potentially one million in the future. This is achieved by batching transactions off-chain and only recording final balances on the blockchain.
- Low Fees: Traditional on-chain BTC transfers can incur high network fees, especially during busy periods. In contrast, Lightning Network transactions typically cost less than $0.01, making them perfect for small or frequent payments.
- Ideal for Micropayments: Whether you're topping up your trading account or sending tiny amounts regularly, the Lightning Network removes economic barriers associated with high fees.
- Enhanced Scalability: By reducing load on the main Bitcoin chain, Lightning helps scale the network sustainably without compromising decentralization or security.

How to Deposit BTC via Lightning Network on OKX
Depositing Bitcoin using the Lightning Network on OKX is simple and takes just a few minutes. Below are detailed instructions for both web and mobile app users.
Step-by-Step Guide: Web Platform
- Log In and Navigate to Assets
Sign in to your OKX account at okx.com. From the dashboard, go to Assets > Deposit. - Select Cryptocurrency and Network
Choose BTC (Bitcoin) as the cryptocurrency. Then, under deposit network options, select BTC-Lightning. Click Next to proceed. - Choose Destination Account and Enter Amount
Decide whether to deposit into your Funding Account or Trading Account. Enter the amount you wish to deposit—recommended between 0.000001 BTC and 0.1 BTC due to per-transaction limits. - Generate a Lightning Invoice
Click Create Invoice. OKX will generate a unique payment request containing a QR code and an invoice string (also known as a BOLT11 invoice). - Complete the Transfer
Copy the invoice or scan the QR code using your external wallet or exchange that supports Lightning withdrawals. Confirm the transaction on your sending platform.
Once confirmed, funds usually arrive within seconds—no waiting for blockchain confirmations.
Step-by-Step Guide: Mobile App
- Open the OKX App and Tap Deposit
Launch the OKX mobile app and tap the Deposit button from the home screen or asset section. - Pick BTC and Select Lightning Network
Search or select BTC, then ensure the deposit network is set to BTC-Lightning instead of the default on-chain option. - Enter Deposit Details
Input the amount (between 0.000001 and 0.1 BTC), choose your destination account (Funding or Trading), then tap Create Invoice. - Send from Your Wallet
Copy the generated invoice or use your phone’s camera to scan the QR code directly from another Lightning-enabled wallet app like Wallet of Satoshi, Phoenix, or BlueWallet.
Your BTC should reflect in your OKX account almost instantly.
⚠️ Note: Always double-check that you're selecting BTC-Lightning as the network. Sending BTC via Lightning to an on-chain address (or vice versa) may result in permanent loss of funds.
