Frequently Asked Questions

What is Qwertycoin?

Qwertycoin is a cryptocurrency designed for people and for everyday use. It improves upon the original Bitcoin blockchain and aims to fulfill its initial purpose of providing individuals and businesses with a fast, efficient and decentralized way of making direct transactions while maintaining your privacy.

When was Qwertycoin created?

Qwertycoin was created in 2017.

Is Qwertycoin a private company and how is it funded?

No, it is 100% open-source software and not a private company funded through an ICO or pre-mining. Development is supported by our community members.

How to run Daemon?

First download the CLI-Wallet (Contains Daemon and Wallet) in Download Section here:

Unzip it and start qwertycoind.exe on Wndows. Or ./qwertycoind on Unix Systems. Now your Daemon synchronized your PC with the network.

How tu run a Masternode?

Cryptonote coin’s wallets can operate through remote daemon without downloading blockchain. It allows to start working quickly when needed. It is quite safe as remote daemon can’t steal your coins, running own node is more secure of course. But these remote nodes are not rewarded anyhow in any CN coin. Only in Qwertycoin such remote nodes are rewarded for their service. We call them Masternodes because this term is well known and to troll other coins Grin.

So, basically, Masternode it is the CLI Qwertycoin daemon running on a machine with open port which allows to connect to it for such light wallets and, most important, mobile wallets in the future. Qwertycoin wallets, connected to Masternode, are paying small fees to that node when are sending transactions through it. These fees are supposed to help to cover the costs of operating Qwertycoin nodes.

These Masternodes are providing service necessary for mobile wallets, and besides are helping to maintain and enlarge Qwertycoin network. We have plans no incentivize such nodes even more in the future.

To start own Qwertycoin masternode all is needed is just a machine with static IP and open port. Machine should have enough CPU power to handle load when parsing blockchain for connected wallets, it can be even spare PC at home. On such machine you can run qwertycoin daemon specifying a wallet address where fees would go like this:

./qwertycoind --restricted-rpc --enable-cors=* --enable-blockchain-indexes --rpc-bind-ip= --rpc-bind-port=8197 --fee-address=QWC1VCm4QNGbyaFeBHdZqGYadFGbTZHQRGhPZuZSS2LxjcBjxH1s9rYHp5Qe5LxLRyPY1bAkXtYGPetZJ5X4Fm2a1ZMkTrZLYL

You can specify any wallet address, it can be your GUI wallet address, even paper wallet. This is the wallet where you will receive fees.
You need to make sure your port is open and not blocked by firewall. If you are running it at home behind router you need to do port forwarding.

If you have PC at home constantly running with fast connection and static IP and want to operate such Masternode to help Qwertycoin network, run daemon as in example and send ous your IP so We can add it do default nodes list.
You can check if your node is running opening its IP in browser like this

and you should see something like this


with your wallet address where fees should go.

You can also run Masternode on VPS with dedicated domain and publish here with description so people can add your node manually if they prefer it. It is not recommended to run node on VPS now specially for Qwertycoin, do it only when you already have spare VPS and it is idling.
For now, do not expect yet to earn a lot of fees because there is very low usage of such remote nodes.

How can i add my Masternode to default node list?

If you have PC at home constantly running with fast connection and static IP and want to operate such Masternode to help Qwertycoin network, run daemon as in example and send a Pull Request on Github So we can add it do default nodes list.

What are the P2P and RPC Ports?

P2P Port: 8196

RPC Port: 8197

What is the max transaction size?

Max transaction size is not limited, but limited to the Blocksize. Currently the limit is a total max of 10 Millions of QWC per Block.

So we estimated max Transaction size for a single Transaction is ~ 100,000. A good Transaction size is lower than 50k.

When will Transaction size increase?

The transaction size will increase after we hit Block height 60,000

At this Point the new Block size is 1,000,000,000 QWC per Block.

How to switch from CLI Wallet to Desktop Wallet?

Just download your Desktop Wallet here and unzip it to your favourite folder. Go to this folder start ./Qwertycoin or Qwertycoin.exe.

Once you open Qwertycoin Wallet, it will automatically create your first Qwertycoin address and start synchronizing with the network. Now you can go to “File > Open Wallet” navigate to your existing Walletfolder and open your name.wallet File.

That’s it.

Pretty simple or?

Import Paperwallet in Desktop Wallet

Import your Paperwallet into Desktop Wallet with only a few clicks:

Your paperwallet generated “Keys for GUI Wallet” to complete these Tutorial.

1. Open Qwertycoin Wallet and go to “File > Import private key“.

If you set all click on OK


How to update Desktop Wallet in Case of Update?

WARNING Connection error: Unexpected symbol

This is just http parsing error, wallets stats requests are causing this. Nothing to be worry about it. Its just a Warning in Debugmode.

Transaction size is too big

You get Errors like this?

2018-02-27 14:48:09 [payments] Error with transfer RPC request to wallet daemon {"code":-4,"message":"Transaction size is too big"}
2018-02-27 14:48:09 [payments] Payments failed to send to {"amount":15000000000000,"address":"QWC1K......utZ4

The max Transaction size is not limited, but limited to the Block size. And currently the max Block size is pretty small to reduce the Blockchain size while Network grow up. After Block 60,000 was mined Block size will increase by Factor 100. So try send smaller Amounts like 50k and MixIn Count 0.

And start mine some QWC 🙂

When QWC will go to Exchange?

The planned Date to go to Exchanges is directly after Block 60,000 was mined. Our Community has start a plan to go faster to any Exchanges, so we create some Donation Addresses to pay the Listing Fee a lot faster. You can donate some Coins to our Addresses, or spent some Hashpower and mine these Coins with our Publicaddress:

Donate Addresses:





BCH (Bitcoin Cash)






How to synchronize Blockchain faster

First: Download a copy of Blockchain in a Single file here: (Use the newest Date).

You need two Files:
blockindexes.dat, blocks.dat you can download each file or download a Archive in a Single Download.

How to setup a blockchain downloaded from the site

0. Close all Qwertycoin related apps and services: Qwertycoin Wallet, walletd, and qwertycoind

1. Open Windows Explorer
2. Type %APPDATA%\qwertycoin for the directory path and press Enter to open it
3. Delete blocks.dat and blockindexes.dat if exist
4. Move downloaded blocks.dat and blockindexes.dat to %APPDATA%\qwertycoin

1. Open Finder
2. Press Cmd+Shift+G or select from menu Go -> Go to Folder and type ~/.qwertycoin and press Enter
3. Delete blocks.dat and blockindexes.dat if exist
4. Move downloaded blocks.dat and blockindexes.dat to directory ~/.qwertycoin

Unable to check for update. Error Socket operation timed out.

You got this Error?

No worry about it. Your Wallet ask our Server if there is a new Version available. But your Connection is maybe to slow, so you got these timed out Error. It’s not a problem. Just click OK. A small problem is that your wallet does not inform you when a new version is available. So please check at regular intervals if a new version is available.
