Backend wallets
===============

LNbits can run on top of many lightning-network funding sources. Currently there is support for
CLightning, LND, LNbits, LNPay, lntxbot and OpenNode, with more being added regularily.

A backend wallet can be configured using the following LNbits environment variables:


### CLightning

Using this wallet requires the installation of the `pylightning` Python package.

- `LNBITS_BACKEND_WALLET_CLASS`: **CLightningWallet**
- `CLIGHTNING_RPC`: /file/path/lightning-rpc

### Spark (c-lightning)

- `LNBITS_BACKEND_WALLET_CLASS`: **SparkWallet**
- `SPARK_URL`: http://10.147.17.230:9737/rpc
- `SPARK_TOKEN`: secret_access_key

### LND (gRPC)

Using this wallet requires the installation of the `grpcio` and `protobuf` Python packages.

- `LNBITS_BACKEND_WALLET_CLASS`: **LndWallet**
- `LND_GRPC_ENDPOINT`: ip_address
- `LND_GRPC_PORT`: port
- `LND_GRPC_CERT`: /file/path/tls.cert
- `LND_GRPC_MACAROON`: /file/path/admin.macaroon


### LND (REST)

- `LNBITS_BACKEND_WALLET_CLASS`: **LndRestWallet**

### LNPay

For the invoice listener to work you have a publicly accessible URL in your LNbits and must set up [LNPay webhooks](https://dashboard.lnpay.co/webhook/) pointing to `<your LNbits host>/wallet/webhook` with the "Wallet Receive" event and no secret. For example, `https://mylnbits/wallet/webhook` will be the Endpoint Url that gets notified about the payment.

- `LNPAY_API_ENDPOINT`: https://api.lnpay.co/v1/
- `LNPAY_API_KEY`: sak_apiKey
- `LNPAY_WALLET_KEY`: waka_apiKey

- `LNTXBOT_API_ENDPOINT`: https://lntxbot.bigsun.xyz/
- `LNTXBOT_KEY`: lntxbotAdminApiKey


### OpenNode

For the invoice to work you must have a publicly accessible URL in your LNbits. No manual webhook setting is necessary.
