Electrum Qtum Wallet-Logo


Qtum is an open sourced public blockchain platform, leveraging the security of UTXO while enabling multiple virtual machines including EVM and the revolutionary x86 VM. Qtum is PoS based and boasts a Decentralized Governance Protocol (DGP) which allows specific blockchain settings to be modified by making use of smart contracts. For instance, the block size of Qtum can be increased without the need of a hard fork.

Electrum Qtum Wallet is a simple, but powerful Qtum wallet. A unique secret phrase (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 Qtums to theft or hardware failure.

NOTICE

Electrum Qtum Wallet is a community-maintained port of Electrum Qtum Wallet, the Bitcoin wallet, to Qtum. It is not an official product of Electrum Technologies GmbH, which does not support it.

Features


  • Use instantly: Electrum Qtum Wallet doesn't need to download the whole blockchain, which is instead maintained on a tamper-proof, remote server.
  • Safe: Your unique secret phrase and private keys are never sent to the Electrum Qtum Wallet 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 seed, you can always recover and restore your wallet...even if you sustain the worst of hardware or software failures.
  • Cold storage: Use Electrum Qtum Wallet 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 Qtum clients, at your convenience.

Frequently Asked Questions


Is there a version of Electrum Qtum Wallet for Android?
Android is not currently supported. If you are looking for a mobile wallet, check out LoafWallet, Jaxx or Coinomi.
Does Electrum Qtum Wallet support Segwit?
Yes.
What is a “seed”?
Electrum Qtum Wallet 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 should I do with my old Qtum addresses and wallet when switching to Electrum Qtum Wallet?
The best way to switch to Electrum Qtum Wallet is to send all the Qtums you have on your old wallet to one of the addresses on your Electrum Qtum Wallet. This way you'll have all your Qtums secured with your seed. Older versions of Electrum Qtum Wallet 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 Qtum Wallet seed.
What does it mean to “freeze” an address?
When you freeze an address, the funds in that address will not be used for sending Qtums. You cannot send Qtums if you don't have enough funds in non-frozen addresses.
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 Qtum Wallet. On all other operating systems, it is located in ~/.Electrum Qtum Wallet.
What is the gap limit?
The gap limit is the maximum number of consecutive unused addresses in your deterministic sequence of addresses. Electrum Qtum Wallet 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.
