LNbits Vetted Extensions

Official registry for vetted LNbits extensions

To submit an extension to this registry add your manifest into the extensions.json file in this repository.

Important

Only submit fully working extensions, the review process is not intended to improve the extension code.

Do not add dependencies, LNbits has plenty of dependencies you can use.

The easier an extension is to review, the quicker the review process will be.

Manifest format

The file MUST use the extensions format:

{
    "id": "gerty",
    "repo": "https://github.com/lnbits/gerty",
    "name": "Gerty",
    "version": "0.1.2",
    "short_description": "Your bitcoin assistant",
    "icon": "https://raw.githubusercontent.com/lnbits/gerty/main/static/gerty.png",
    "archive": "https://github.com/lnbits/gerty/archive/refs/tags/0.1.2.zip",
    "hash": "baff0b6162ffb65cc0b4c721a4aa40a7d3d48acd55a3e344cba3eb1d35cf2074"
},

For an exensions local manifest.json use the repos format:

{
    "repos": [
        {
            "id": "gerty",
            "organisation": "lnbits",
            "repository": "gerty"
        }
    ]
}

Paid extensions

It is possible for developers to require a payment for their extensions. In order to do so an extension release must have this field:

   "pay_link": "# payment URL"

Example:

{
    "id": "testext",
    "repo": "https://github.com/lnbits/testext",
    "name": "Test Extension",
    "version": "0.5",
    "short_description": "Private Test Extension",
    "icon": "https://raw.githubusercontent.com/lnbits/example/main/static/bitcoin-extension.png",
    "archive": "https://legend.lnbits.com/paywall/download/BNv6XjB4DKLBQt7q5w4HuG",
    "pay_link": "https://legend.lnbits.com/paywall/api/v1/paywalls/invoice/BNv6XjB4DKLBQt7q5w4HuG",
    "hash": "455527407fcfdc5e8aba93f16802d1083d36dcdfdde829f919cee07420791d61"
}

The Paywall LNbist Extension can be used to serve the extension zip file.

If you do not want to use the Paywall LNbits Extension to server your extension, but instead you want to use your own paywall, then the pay_link endpoint must follow these specifications:

HTTP Request	HTTP Response	Description
GET pay_link	{ "amount": 5 }	Get the amount in `sats` required by this extension release.
GET pay_link?amount=5	{ "payment_hash": "04c33f37d01aff...fd7c407a", "payment_request": "lnbc50n1pju...n7h8gucqn2cgau" }	Request an invoice for the specified amount (or higher).
WS pay_link/{payment_hash}	{"paid": true|false}	Open a websocket to be notified when the invoice has been paid.

In order to download the file one must add the payment_hash and an version (optional) query parameters to the archive URL. Eg:

GET https://legend.lnbits.com/paywall/download/BNv6XjB4DKLBQt7q5w4HuG?payment_hash=3bf...7ec&version=v0.1

Lighter ZIP archive

• documentation, tests and other type of files should not be included in the zip archive generated when a GitHub release is created
• keep the README.md and LICENSE files in the zip as these are required!
• in order to exclude these files one must:
  • create a .gitattributes file (on the top level of the repo)
  • add a line for the ignored files/dirs: tests/ export-ignore

Checking the changes before sending a pull request

• after editing the manifest.json file in this repo you should run python3 check.py as a sanity check
• you can run python3 check.py foo bar only to run sanity checks on extensions named foo and bar
