# Flash Node Passes
This guide covers the authentication process specifically for **Flash Pass** holders.
## What is Flash Pass?
Flash Pass is a limited-access tier that provides entry to exclusive Flash-only RPC node locations. It's designed for users who need access to specific high-demand locations at a lower entry point.
## Flash Pass Characteristics
| Feature | Flash Pass |
| ------------------- | -------------------------------- |
| Renewal Fee | $100 |
| Rate Limit | Up to 400 Request per Second |
| Request Limit | Unlimited |
| Pass ID Format | `F{number}` (e.g., F123) |
| Double IP | Not available |
| Max authentications | **1 IP total** |
| Location access | Flash-only locations exclusively |
## Flash-Only Locations
Flash Pass holders can **only** authenticate to these locations:
| Location | Blockchain |
| -------------- | ------------------- |
| Los Angeles | Solana |
| London | Solana |
| Salt Lake City | Solana |
| Frankfurt | Binance Smart Chain |
> **Important:** Flash Pass cannot access any other locations. Attempting to select non-Flash locations will result in an error.
## Single IP Limitation
Unlike other pass types, Flash Pass has a strict **one IP per pass** limitation:
* You can only authenticate **one IP address** total with your Flash Pass
* This IP can be at any one Flash-only location
* To change locations, you must first delete your existing authentication
## Step-by-Step Authentication
{% stepper %}
{% step %}
**Start the Process**
Open a **Direct Message** with the Auth Bot and type:
```
!rpc auth
```
{% endstep %}
{% step %}
**Select Your Flash Pass**
From the dropdown menu, select your Flash Pass (shown as `F{number}`).
> **Subscription Check:** If your Flash Pass subscription has expired, you'll need to renew before proceeding.
> {% endstep %}
{% step %}
**Choose a Flash Location**
Select from the available Flash-only locations:
```
Los Angeles πΊπΈ
London π¬π§
Salt Lake City (Flash) πΊπΈ
Frankfurt BSC π©πͺ
```
If you select a non-Flash location you'll receive an error message:
"You can only authenticate to Los Angeles or London with your Flash Pass."
{% endstep %}
{% step %}
**Enter Your IP Address**
Click **Auth** and enter your **public IPv4 address**.
IP requirements:
* Valid IPv4 format (e.g., `203.0.113.50`)
* Must be a **public** IP address
* Cannot be private IP ranges (10.x.x.x, 172.16-31.x.x, 192.168.x.x)
{% endstep %}
{% step %}
**Confirmation**
Upon successful authentication you will see:
"Authed IP: \[your IP]"\
"Node URL in #node-urls"
{% endstep %}
{% endstepper %}
## Changing Your Authenticated Location
Since Flash Pass only allows one IP total, to change your location:
1. Delete your current authentication using `!rpc delete`
2. Select your Flash Pass entry from the list
3. Click **Delete** to remove it
4. Run `!rpc auth` again
5. Select your new desired Flash location
## Creating Rentals with Flash Pass
Flash Pass holders can rent out their authentication slot. The pricing tier for Flash rentals is lower than Thor Pass rentals:
### Flash Pass Rental Pricing (Check discord server for recent pricing)
| Period | IP Updates | Flash Pass Price |
| ------- | ---------- | ---------------- |
| 2 Hours | 2 | 0.25 SOL |
| 1 Day | 3 | 0.5 SOL |
| 1 Week | 5 | 1 SOL |
| 1 Month | 9 | 2 SOL |
### How to Create a Flash Rental
1. Run `!rpc auth` and select your Flash Pass
2. Choose a Flash-only location
3. Click **Rent** instead of **Auth**
4. Enter:
* Renter's Discord ID
* Rental period (`2H`, `1D`, `1W`, or `1M`)
* Payment transaction ID
> **Note:** While you have an active rental, you cannot authenticate your own IP until the rental expires.
## Common Error Messages (FAQ)
"You can only authenticate to Los Angeles or London with your Flash Pass"
You selected a location that is not Flash-exclusive. Choose from: Los Angeles, London, Salt Lake City (Flash), or Frankfurt BSC.
"You already authenticated one IP address for your Flash Pass"
Flash Pass only allows one IP total. To authenticate a new IP:
1. Run `!rpc delete`
2. Remove your existing authentication
3. Try `!rpc auth` again
"This location is exclusive to Flash Pass only"
This message appears for non-Flash pass holders trying to access Flash locations. Only Flash Pass can access these locations.
## Flash Pass vs Other Passes
| Comparison | Flash Pass | Thor Pass Types |
| -------------- | ----------------------- | ----------------------- |
| Locations | Flash-only (4) | All general (many) |
| Max IPs | 1 total | 4 to Unlimited |
| Double IP | No | Elite |
| Rental pricing | Lower tier | Higher tier |
| Best for | Specific location needs | Flexible multi-location |
## Tips for Flash Pass Holders
1. **Choose wisely** - Since you only get one IP, pick the location closest to your infrastructure
2. **Check latency** - Before authenticating, verify which Flash location offers the best latency for your needs
3. **Consider rentals** - If you need temporary access to other locations, you can rent slots from other pass holders
4. **Plan changes** - Remember that changing locations requires deleting and re-authenticating
