Lnd has several pluggable back-end chain services including grsd (a full-node), groestlcoind, and neutrino (a new experimental light client).

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.

Changelog 0.8.2
• We now support gifting mgro to the peer when opening a channel, via push_msat, providing a brand new way to lose money!
• Invoice routehints can be overridden using exposeprivatechannels: try setting to [] to eliminate all of them to fit your invoice in twitter messages!
• Wallet withdraw transactions now set nLocktime, making them blend in more with other wallets.
• Preliminary support for plugins hooks which can replace the default groestlcoin-cli with other blockchain querying methods (API may change in future releases though!).
• listforwards now records the outgoing short_channel_id, even if it wasn't possible to start forwarding.
• Plugins can set additional feature bits, for more experimentation.
• More than one plugin can register for the htlc_accepted hook: others will become multi-user in future releases.
• Prevent a case where grossly unbalanced channels could become unusable.
• New config option --large-channels (also known as 'wumbo') which enables opening channels of any size. (Note that your peer must also support large channels.)
• This release includes a keysend plugin, which will enable receiving 'keysend' payments, as first introduced by Lightning Labs. Note that the included keysend plugin is receive only for this release. Nodes which do not want the hassle of spontaneous unrequested payments should add 'disable-plugin=keysend' to their config!
• We'll now announce multiple connection endpoints for a single 'type', e.g. multiple IPv4 addresses.
• Big performance improvement in the pay command (~1s speedup on average).
• c-lightning nodes can now participate in creating larger channels (with the --large-channel config option).
• We now wait until the first payment through a channel before updating the feerate; this should help with some spurious closures at channel open or re-connect that were occurring against older versions of other implementations.
• A new command getsharedsecret for getting the BOLT-compliant shared secret finding for a node and a point.
• Facilities for building rendez vous compatible onions has been added to the onion devtool.
• Plugin options will now respect the type they were given in the manifest.
• Fixes with plugin cleanups and hangs.
• Python2 has been removed as a dependence.

Features
• Creating channels.
• Closing channels.
• Completely managing all channel states (including the exceptional ones!).
• Performing path finding within the network, passively forwarding incoming payments.

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.

Changelog 0.3.3

HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is Hodl GRS's core design principle. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

Features
• Simplified payment verification for fast mobile performance
• No server to get hacked or go down
• Single backup phrase that works forever
• Private keys never leave your device
• Import password protected paper wallets
• Payment protocol payee identity certification
• Apple Watch support

This application is licensed under MIT. There is no warranty and no party shall be made liable to you for damages. If you lose coins due to this app, no compensation will be given. Use this app solely at your own risk.

Groestlcoin Sentinel Testnet is a great solution for anyone who wants to test the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts TPUB's, UPUB'S, VPUB's and individual Groestlcoin Testnet address. Once added you will be able to view balances, view transactions, and (in the case of TPUB's, UPUB's and VPUB's) deterministically generate addresses for that particular wallet.
Groestlcoin Sentinel Testnet is a fork of Groestlcoin Samourai Testnet Wallet with all spending and transaction building code removed.

Changelog v3.5.06:
• Added adaptive icons for Android 8 and above
• Add blockbook testnet blockexplorer

Features
• Sweep P2PKH, Segwit BIP49 (P2SH-P2WPHK) and Segwit BIP84 (bech32) amounts into selected account/address
• Broadcast hex tx
• Receive address closes upon receipt of testnet groestlcoins
• Refresh button
• Multiple blockexplorers support
• Haptic PIN entry support
• Open source and unlicensed.
• No Private Keys - Groestlcoin Sentinel Testnet only uses Public Keys. It never knows or never asks for your Private Keys.
• Track multiple TPUB's, UPUB's, VPUB's or Addresses - Add multiple TPUB's, UPUB's, VPUBS's or addresses to your Groestlcoin Sentinel Testnet Watchlist to keep track of balances, transactions, and accept payments into any added wallet or address.
• Deterministically derives Groestlcoin Testnet Addresses - Deterministically derive new Groestlcoin Testnet addresses associated with your added wallets without needing access or knowledge to your private keys.
