Evilcoin is a full node and desktop wallet for the Evil Coin cryptocurrency, written in Qt and forked from the Bitcoin and Litecoin codebase. It is aimed at Windows users who want to run their own copy of the Evil Coin blockchain rather than rely on a third-party service. The software is free and open source, and its code is published on GitHub.
Before you install it, know its status. The project has had no code updates since December 2017, and the latest listed version is v1.0. Software in this state may not receive fixes for newer operating systems or security issues, so treat Evilcoin as a legacy tool for experimentation and archival use rather than a daily wallet for significant funds. This page covers what the program does, how to install it, and how to stay safe.
Why Run a Full Node Instead of a Web Wallet
A web wallet or exchange account is convenient, but you rely on the operator to keep your keys safe and to report balances honestly. A full node changes that arrangement. Your machine stores the chain history and checks every transaction against consensus rules, so you do not have to take anyone's word for it.
The trade-off is time and disk space. Initial synchronization can take hours or longer depending on your connection and hardware, and the blockchain grows over time. Users who only send a small payment now and then may find a lighter option more practical, while those who value independence will accept the wait.
Key Terms You Will See in the Wallet
A blockchain is the shared ledger that every node keeps a copy of. A seed phrase is a list of words that can restore a wallet. Anyone who holds it can spend the funds, so it should be written down offline and never typed into a website.
Bitcoin-derived wallets commonly store keys in a file called wallet.dat. Check the data folder after installation to confirm what Evilcoin creates, and back up that file before you move it or reinstall Windows. Consensus rules are the conditions every node checks, such as valid signatures and correct block structure.
Practical Scenarios for a Legacy Full Node
Some people use an older full node to study how Bitcoin-style blockchains work. Running one locally lets you watch block propagation, inspect transactions and see how a wallet handles keys, all without risking a large balance.
Developers and researchers may also run an archived client to reproduce older behavior or compare code across forks. Because this software predates many current security standards, it is best kept in a separate test environment rather than on the computer you use for banking or email.
Key features
Full node
Qt desktop wallet
Bitcoin and Litecoin lineage
Open source on GitHub
Supported coins
Evilcoin is built for the Evil Coin network, which is derived from the Bitcoin and Litecoin codebases. The program is designed around that single chain, so it is not a multi-asset wallet and you should not expect to hold unrelated tokens in it.
How to install Evilcoin on Windows
- 1
Get the installer from a trusted source
Download only from the official website or the project's GitHub Releases page. Avoid mirrors and file-sharing sites, because a modified installer can carry malware. Choose the Windows build or installer offered on that page.
- 2
Verify the file
Compare the SHA-256 checksum of the downloaded file with the value published alongside the release. If no checksum or signature is listed on the release page, do not run the file. Look for verification details in the repository before continuing.
-
Install and first launch
Run the installer and choose a data folder with enough free disk space for the blockchain. Let the node begin syncing. When the wallet shows a seed phrase, write it down on paper right away and keep your wallet file backed up.
How to use Evilcoin
Evilcoin works like other full node wallets: the node has to sync first, and only then can you rely on the wallet. Plan the first session for a time when you have a stable connection and free disk space, because synchronization cannot be rushed.
- Install the program and launch it once so it creates its data folder.
- Let the node finish synchronizing with the network before you trust any balance on screen.
- Back up the wallet file and write down the seed phrase offline, then store copies in separate safe places.
- Create a receiving address, then send a small test amount to yourself to confirm the wallet works.
- Check the transaction history and confirm the amounts before you move larger sums.
- Close the program cleanly when you finish, so the node can write its data correctly.
Pros & cons
- Free and open source, with publicly viewable code on GitHub
- Full node lets you verify transactions yourself instead of trusting a server
- Native Windows build or installer is available
- Graphical Qt interface avoids the need for a command line for everyday tasks
- No code updates since December 2017
- No guarantee of recent security fixes or compatibility updates
- Full node synchronization takes time and disk space
- Single-chain design, so it does not manage other coins
Is Evilcoin safe?
Evilcoin has not been updated since December 2017, so it carries risks that actively maintained wallets reduce. Use it for small experiments unless you have reviewed the code and understand the trade-offs. Download only from the official website or the GitHub Releases page, never from third-party download portals. Verify the SHA-256 checksum or signature before running the installer, and check the latest version on the official website in case a newer build exists. Never enter your seed phrase on third-party websites or in messages from anyone claiming to be support. Keep backups offline and store them somewhere a malware infection cannot reach.
- Official source only. Download from github.com/coins4lunch/evilcoin. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Evilcoin sits in the same category as Litecoin Core and Dogecoin Core, which are also full nodes and wallets descended from Bitcoin. The difference is the network: Evilcoin serves the Evil Coin chain, so it does not connect you to Litecoin or Dogecoin. Monero CLI takes a different approach, offering a command-line daemon and wallet for the Monero network, while Qtum Core serves its own separate chain. If you want a node and wallet that is still receiving code changes, compare the listed options and check each project's release history yourself before deciding.

Frequently asked questions
It can be used with care, but it has not received code updates since December 2017, so it carries risks that maintained wallets reduce. Verify the installer's checksum, keep your seed phrase offline, and hold only small amounts while you learn how the software behaves.
Yes. The program is listed as free and open source, so there is no charge to download or use the software itself. Sending transactions on the Evil Coin network may involve network fees, which are a separate cost from the program.
Evilcoin is used to run a full node and wallet for the Evil Coin cryptocurrency on Windows. People use it to verify the chain themselves, send and receive coins, and study how a Bitcoin-derived client works. It is not a general-purpose wallet for other coins.
No. The latest code update in the repository is from December 2017, and the newest version listed is v1.0. Expect no bug fixes or compatibility updates, and plan accordingly before you store any meaningful amount of funds.
Download the Windows build or installer from the official website or the GitHub Releases page, check its SHA-256 checksum, and run the installer. Then let the node sync before relying on the wallet. The installation steps above walk through each part of the process.
A full node is software that stores and checks the entire blockchain on your own computer. It verifies transactions against consensus rules without relying on a third party. Running one improves independence, but it requires disk space and time to synchronize.
Verdict
Evilcoin is best suited to Windows users who want to explore a Bitcoin-derived full node and understand how the Evil Coin chain works. It is free, open source and straightforward to inspect, but its code has not changed since December 2017. That makes it a poor choice for holding significant funds or for anyone who needs current security patches. Treat it as a learning and archival tool, keep test amounts small, and review the alternatives before committing any savings.
