## How to Deposit to Lnfi from OKX?
{% hint style="info" %}
Depositing assets on Lnfi works slightly differently from other blockchains.
Since Lnfi is built on the Lightning Network, a Lightning invoice **must be** generated by the receiver to send Bitcoin, Satoshis, or Taproot Assets from the sender.
{% endhint %}
In this **deposit** scenario, your Nostr address on Lnfi functions as the receiver, while your OKX account serves as the sender.
**To complete the deposit, you’ll need to generate a Lightning invoice using your Nostr address on Lnfi and provide it to your OKX account for payment.**
Here’s how to generate a Lightning invoice on Lnfi:
1. Go to Lnfi Asset Dashboard, tap on \[Deposit].
2. Select the \[Receive Token] type and input the \[Amount] to receive, then tap on \[Create Invoice].
{% hint style="info" %}
Currently only SATS is supported. \
\
SATS is the minimum unit of BTC, 100 million SATS=1 BTC. \
It is essentially BTC, not BRC20 SATS.
{% endhint %}
3. Copy the Invoice ID. (starts with Inbc....)
4. Head over to your OKX account. Go to Funding > Withdrawal.\
Select \[BTC]
5. For On-chain withdrawal, select \[Lightning] for Network.
6. Paste the copied Lightning Invoice ID. If you have sufficient amount of the \[Receive Token], you can proceed to complete the deposit by tapping on \[Next].
7. Once completed, the \[Receive Token] will be credited to your Nostr address. The process should be nearly instantaneous, thanks to the Lightning Network's unique capability for fast transactions.
