## How to Deposit to Lnfi from OKX?

{% hint style="info" %}
Depositing assets on Lnfi works slightly differently from other blockchains.&#x20;

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.&#x20;

**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].

<figure><img src="/files/5Yx7S9zpZGE8A8GxHrnH" alt=""><figcaption></figcaption></figure>

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 %}

<figure><img src="/files/R9RQL3OCxtyAhxjN7Y0e" alt=""><figcaption></figcaption></figure>

3. Copy the Invoice ID. (starts with Inbc....)

<figure><img src="/files/EyQhCkHYuzQ1cvRhGd3s" alt=""><figcaption></figcaption></figure>

4. Head over to your OKX account. Go to Funding > Withdrawal.\
   Select \[BTC]&#x20;

<figure><img src="/files/A3og44dTYHhY45hS84zt" alt=""><figcaption></figcaption></figure>

5. For On-chain withdrawal, select \[Lightning] for Network.

<figure><img src="/files/LMYxRWzB37zAqj9jLUHz" alt=""><figcaption></figcaption></figure>

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].

<figure><img src="/files/uDSxY5ZCDINCzX9KRfGN" alt=""><figcaption></figcaption></figure>

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.
