How to deposit BTC using Lightning Network

When depositing BTC, you will now have three network options to choose from:

• Bitcoin (on-chain)  
• Binance Smart Chain (BEP20)  
• Lightning Network  

The Lightning Network provides an additional option designed for speed and efficiency—especially for smaller or time-sensitive transactions. 

The Lightning Network can be used if you want to:

• Transfer BTC quickly between platforms  
• Minimize transaction fees  
• Send smaller amounts efficiently  

For larger transfers, or when sending to wallets that do not support Lightning, the standard Bitcoin network may be more appropriate. 

• Log in to your Ndax account.  
• Select Wallet from the left-hand side menu.  
• Choose BTC.  
• Select Receive at the bottom of the screen.  
• Choose the Lightning Network as the deposit method.  

Create a Lightning Invoice

• Enter the amount of BTC you want to deposit.  
• This is required before creating an invoice.
