# LNURLw
|
|
|
|
## Create a static QR code people can use to withdraw funds from a Lightning Network wallet
|
|
|
|
LNURL is a range of lightning-network standards that allow us to use lightning-network differently. An LNURL withdraw is the permission for someone to pull a certain amount of funds from a lightning wallet.
|
|
|
|
The most common use case for an LNURL withdraw is a faucet, although it is a very powerful technology, with much further reaching implications. For example, an LNURL withdraw could be minted to pay for a subscription service. Or you can have a LNURLw as an offline Lightning wallet (a pre paid "card"), you use to pay for something without having to even reach your smartphone.
|
|
|
|
LNURL withdraw is a **very powerful tool** and should not have his use limited to just faucet applications. With LNURL withdraw, you have the ability to give someone the right to spend a range, once or multiple times. **This functionality has not existed in money before**.

## Usage
|
|
|
|
#### Quick Vouchers
|
|
|
|
LNBits Quick Vouchers allows you to easily create a batch of LNURLw's QR codes that you can print and distribute as rewards, onboarding people into Lightning Network, gifts, etc...
|
|
|
|
1. Create Quick Vouchers\
|
|
|
|
- select wallet
|
|
- set the amount each voucher will allow someone to withdraw
|
|
- set the amount of vouchers you want to create - _have in mind you need to have a balance on the wallet that supports the amount \* number of vouchers_
|
|
2. You can now print, share, display your LNURLw links or QR codes\
|
|
|
|
- on details you can print the vouchers\
|
|
|
|
- every printed LNURLw QR code is unique, it can only be used once
|
|
3. Bonus: you can use an LNbits themed voucher, or use a custom one. There's a _template.svg_ file in `static/images` folder if you want to create your own.\
|
|
|
|
|
|
#### Advanced
|
|
|
|
1. Create the Advanced LNURLw\
|
|
|
|
- set the wallet
|
|
- set a title for the LNURLw (it will show up in users wallet)
|
|
- define the minimum and maximum a user can withdraw, if you want a fixed amount set them both to an equal value
|
|
- set how many times can the LNURLw be scanned, if it's a one time use or it can be scanned 100 times
|
|
- LNBits has the "_Time between withdraws_" setting, you can define how long the LNURLw will be unavailable between scans
|
|
- you can set the time in _seconds, minutes or hours_
|
|
- the "_Use unique withdraw QR..._" reduces the chance of your LNURL withdraw being exploited and depleted by one person, by generating a new QR code every time it's scanned
|
|
2. Print, share or display your LNURLw link or it's QR code\
|
|
|
|
|
|
**LNBits bonus:** If a user doesn't have a Lightning Network wallet and scans the LNURLw QR code with their smartphone camera, or a QR scanner app, they can follow the link provided to claim their satoshis and get an instant LNBits wallet!
