C-lightning is a lighweight, highly customizable and standard compliant implementation of the Lightning Network protocol.
C-lightning only works on Linux and Mac OS, and requires a locally (or remotely) running groestlcoind (version 2.16.0 or above) that is fully caught up with the network you're testing on.

Features
• Creating channels.
• Closing channels.
• Completely managing all channel states (including the exceptional ones!).
• Performing path finding within the network, passively forwarding incoming payments.
• Sending outgoing onion-encrypted payments through the network.
• Automatic channel management (autopilot).

GRSPay Testnet is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with GRSPay Testnet go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your tpubkey or vpubkey.

GRSPay Testnet is available at https://testnet.grspay.com/

• Open Source - MIT license

FAQ
### How to use WooCommerce store with GRSPay Testnet?
https://www.youtube.com/watch?v=qNMTDEPhWhY

### Does GRSPay Testnet need my private key?

Absolutely not. The fact that GRSPay Testnet never needs access to your master private key for on-chain transactions is a huge security advantage. Even if our server gets hacked, your funds from the on-chain transactions are always safe. Securing your on-chain funds, comes down to your own security.
When we will support lightning node, GRSPay Testnet technically will have access to the keys (macarons) of your LN.

### Address re-use - How GRSPay Testnet creates a different address?

GRSPay Testnet generates a different address for each invoice. The address is derived from your tpubkey or vpubkey. Your private keys are never uploaded or required by GRSPay Testnet. The software only needs your extended public key. You can create your private key in your software or hardware wallet and import the public key (tpub/vpub) into GRSPay Testnet so that it can derive addresses from it. Meanwhile, you should stick to the best practices for protecting your private key.

### What e-commerce integrations are available?

Currently, GRSPay Testnet has integrations with the following e-commerce platforms:
- WordPress / WooCommerce
- Magneto
- Drupal
- Prestashop
- Custom integration

### Does GRSPay Testnet Support Lightning Network Testnet?

No not yet but coming soon.

## Invalid Status Code:301 when pairing the store with GRSPay Testnet.

Please make sure to enter the URL of the host you're trying to pair with correctly, including the HTTP(s) part. For example https://testnet.grspay.com

## Invalid derivation scheme

If you're getting this error, this means that you have not connected your wallet to GRSPay Testnet. In Store>Settings> Derivation Scheme, on the right-hand side click modify and set up your derivation scheme correctly.

It is appreciated if feedback of the following is provided:
1. Are you able to register at GRSPay Testnet?
2. Are you able to create a store?
3. Are you able to create an invoice?
4. Are you able to create a POS?
5. Are you able to receive payments through GRSPay Testnet?
6. Are you able to setup your derivation scheme?
7. Are you able to setup 2 factor authentication?

To use Zeus, you must have a running Lightning Network Daemon (lnd). You must provide Zeus GRS with your node's hostname, port number, and the lnd macaroon you choose to use in hex format.
If you're running a Unix-based operating system (eg. macOS, Linux) you can run xxd -ps -u -c 1000 /path/to/admin.macaroon to generate your macaroon in hex format.

Features:
• Scan LNDconnect functionality
• Dark and light theme
• Option to lock app with a pin
• Open Source

KWH-GRS is a browser extension that connects to c-lightning or Eclair nodes and enables interactions with Lightning apps.

Features
• Browse balance and latest transactions
• Webln support
• Pay highlighted invoice with a context menu click
• Handle lightning: links
• "Generate invoice here" context menu
• Manual payments and invoice creation
• Instant notifications on received payments
• No window popups, all interactions happen in the browserAction popup.
• Open Source - MIT license

Requirement to use KWH-GRS
• a c-lightning node with a Spark in front of it
• an Eclair node with the API enabled and accessible

Caveats
• If you are using Google Chrome, consider enabling the Experimental Extension APIs flag on chrome://flags for a better experience.
• If you are using Eclair, the WebSocket won't connect on Firefox, so you won't get notifications when a payment is sent or received, the experience will not be as nice as if it did.

Now you can lookup how many LN nodes and channels there are on GRS testnet.

Features
• Light and Dark Mode
• Ability to create invoice to donate for development funds
• Open source

Requirements
• If connecting to a remote LND, you need to set lndHost and lndDir params. lndDir must have admin.macaroon and tls.cert files.
• For c-lightning set --daemon clightning and specify clightningDir if not using default location. Note that c-lightning supplies less data about channels than LND.

This app features a standalone SPV Groestlcoin testnet wallet with a fully functional built-in Lightning node. It allows to send and receive regular on-chain transactions as well as off-chain Lightning payments.

Features
• GLW uses 'Olympus servers' which serve multiple functions, including storing an encrypted backup, functioning as a watchtower, and helps with routing of payments across the Lightning Network.
• Tor support
• Off-chain data loss protection is present: in case of emergencies such as phone loss you will only need a mnemonic phrase to recover both on-chain Groestlcoin testnet balance and off-chain Lightning balance.
• Back channel states on Google Drive and on Olympus server
• Storage tokens: These are special cryptographic entities provided by Olympus server in exchange for a Lightning payment. You can think of them as single-use tickets which are used to anonymously store data such as lightning channel backups or watch revoked channel states on Olympus server
• Watchtower service is present: don't worry about getting an online periodically.
• Fingerprint support
• Ability to use trusted groestlcoin node
• Multiple Fiat currencies
• Migration tool to move wallet data to another phone by making snapshots (NOT encrypted)

Groestlcoin Eclair requires Groestlcoin Core 2.17.1 or higher. If you are upgrading an existing wallet, you need to create a new address and send all your funds to that address.
Groestlcoin Eclair needs a synchronized, segwit-ready, zeromq-enabled, wallet-enabled, non-pruning, tx-indexing Groestlcoin Core node.
Groestlcoin Eclair will use any GRS it finds in the Groestlcoin Core wallet to fund any channels you choose to open. Eclair will return GRS from closed channels to this wallet.
You can configure your Groestlcoin Node to use either p2sh-segwit addresses or bech32 addresses, Groestlcoin Eclair is compatible with both modes.

Features
• Creating channels.
• Closing channels.
• Completely managing all channel states (including the exceptional ones!).
• Mainnet and testnet support

Groestlcoin Eclair is developed in Scala, a powerful functional language that runs on the JVM, and is packaged as a JAR (Java Archive) file. We provide 2 different packages, which internally use the same core libraries:
eclair-node (headless application that you can run on servers and desktops, and control from the command line): https://github.com/Groestlcoin/eclair/releases/download/v0.3.2.1/eclair-node-0.3.2.1-4852bfc.jar
