Electrum-LTC


Electrum-LTC is a simple, but powerful Litecoin wallet. A twelve-word security passphrase (or “seed”) leaves intruders stranded and your peace of mind intact. Keep it on paper, or in your head... and never worry about losing your litecoins to theft or hardware failure. No waiting, no lengthy blockchain downloads and no syncing to the network.

IMPORTANT NOTICE (August 1, 2017)

On July 31, around 13:00 UTC, an attacker exploited a vulnerability in the virtualization software employed by this website's host to replace the sources and Windows binaries of Electrum-LTC 2.8.3.5 with modified versions. We were made aware of the issue by 17:30 UTC, and promptly restored the original files. We then proceeded to carefully move the website to a new host that would be immune to said vulnerabilities.

If you downloaded a source distribution or a Windows binary of Electrum-LTC 2.8.3.5 from this website during the above time range, and did not verify its digital signature, your computer may have been infected by malware, and you should take action immediately. Note that the digital signatures have been available and valid all along.

Previous Stable Version: 2.8.3.5 (released 2017-06-23)

  Make sure you back up your wallet/seed if upgrading from an earlier version.  

Release Notes

  • The wallet file format has been upgraded. This upgrade is not backward compatible, which means that a wallet upgraded to the 2.8 format will not be readable by earlier versions of Electrum. Multiple accounts inside the same wallet are not supported in the new format; the Qt GUI will propose to split any wallet that has several accounts. Make sure that you have saved your seed phrase before you upgrade Electrum.
  • Support for the new Litecoin P2SH address version (multisig addresses now start with M). Old multisig wallets must be regenerated from seed to convert them to the new address type.
  • Wallet file encryption using ECIES: A keypair is derived from the wallet password. Once the wallet is decrypted, only the public key is retained in memory, in order to save the encrypted file.
  • Seed phrases can be extended with a user-chosen passphrase. The length of seed phrases is standardized to 12 words, using 132 bits of entropy. In the wizard, the type of the seed is displayed in the seed input dialog.
  • Invoices and contacts are stored in the wallet file and are no longer shared between wallets. Previously created invoices and contacts files may be imported from the menu.
  • This version introduces a separation between wallets types and keystores types. 'Wallet type' defines the type of Bitcoin contract used in the wallet, while 'keystore type' refers to the method used to store private keys. Therefore, so-called 'hardware wallets' will be referred to as 'hardware keystores'.
  • Hardware keystores: The Ledger Nano S is supported.
  • Hardware keystores: Support for Ledger firmwares older than version 1.0.1 has been dropped.
  • Hardware keystores can be used as cosigners in multi-signature wallets. Multiple hardware cosigners can be used in the same multisig wallet. One icon per keystore is displayed in the satus bar. Each connected device will co-sign the transaction.
  • The daemon requires wallets to be explicitly loaded before commands can use them. Wallets can be loaded using: electrum-ltc daemon load_wallet [-w path]. This command will require a password if the wallet is encrypted.
  • Qt GUI: The Address tab is hidden by default, can be shown with Ctrl-A.
  • Qt GUI: a blue icon is shown when connected using a proxy.
  • SPV: add blockchain checkpoints, configurable by user.
  • Support for Replace-By-Fee (RBF).
  • Add Testnet support (--testnet option).
  • Experimental support for Segregated Witness (testnet only).

Features


  • Use instantly: Electrum doesn't download the blockchain or require your computer to sync with the network. Instead, it is maintained on a tamper-proof, remote server.
  • Safe: Your unique twelve word pass-phrase and private keys are never sent to the Electrum-LTC servers. All information received from the server is verified using Simplified Payment Verification (SPV).
  • Forgiving: Never be concerned about losing your wallet! With your unique twelve-word seed, you can always recover and restore your wallet...even if you sustain the worst of hardware or software failures.
  • Cold storage: Use Electrum-LTC to generate and manage your secure offline wallets, enabling you to take some or all of your funds completely offline.
  • Accessible: Export your private keys to other Litecoin clients, at your convenience.

Frequently Asked Questions


Is there a version of Electrum-LTC for Android?
Android is not currently supported. If you are looking for a mobile wallet, check out LoafWallet, Jaxx or Coinomi.
Does Electrum-LTC support Segwit?
Support for native Segwit transactions is in the works. However, this is not needed for normal operation, even now that the Segwit soft fork has activated.
What is the Seed?
Electrum-LTC uses a 128-bit random seed to generate your private keys. The seed can be represented as a 12-word mnemonic code. You do not need to perform regular backups, because your wallet can be recovered from the seed that you can memorize or write on paper.

Seed Example

What is the gap limit?
The gap limit is the maximum number of consecutive unused addresses in your deterministic sequence of addresses. Electrum-LTC uses a gap limit to stop looking for addresses. This is set to 5 by default, so the client generates new addresses until 5 unused addresses are found.
What does it mean to “freeze” an address?
When you freeze an address, the funds in that address will not be used for sending litecoins. You cannot send litecoins if you don't have enough funds in non-frozen addresses.
What should I do with my old Litecoin addresses and wallet when switching to Electrum-LTC?
The best way to switch to Electrum is to send all the litecoins you have on your old wallet to one of the addresses on your Electrum wallet. This way you'll have all your litecoins secured with your seed. Older versions of Electrum could import private keys from another client, but then you had to backup those keys separately, as they could not be restored by the Electrum seed.
Where is my wallet file located?
A default wallet file called default_wallet is created under the /wallets folder when you first run the application. On Windows, this folder is located in \Users\YourUserName\AppData\Roaming\Local\Electrum-LTC. On all other operating systems, it is located in ~/.electrum-ltc.
What is a blockchain?
A blockchain is a long record of every single transaction ever made. Each litecoin traded for a good or service is marked on the ledger with a transaction id and the origination and target wallet addresses.
