Installation Requirements

System Requirements

  • Operating Systems: Windows, macOS, Linux
  • Memory: 512MB RAM minimum
  • Storage: 200MB available space
  • Internet: Broadband connection
  • Python: 3.6+ (for source installation)

Security Prerequisites

  • Clean System: Malware-free computer
  • Secure Environment: Private location
  • Backup Materials: Pen and paper
  • Verification Tools: GPG software
  • Hardware Wallet: Optional but recommended

Step-by-Step Installation

1

Download Verification

Download Electrum only from the official website (electrum.org). Verify the GPG signature of the downloaded file using Thomas Voegtlin's public key. This step ensures you have an authentic, untampered copy of the software. Never download from third-party sources.

2

Installation Process

Run the installer with administrator privileges. Choose installation location carefully (avoid system directories). Select components based on your needs (full installation recommended for new users). Complete installation and launch Electrum for the first time.

3

Wallet Creation

Select "Create a new wallet" and choose wallet type (Standard wallet recommended for beginners). Name your wallet file appropriately. Select "Create a new seed" for new wallets. Write down the 12-word seed phrase exactly as displayed - this is crucial for wallet recovery.

4

Seed Phrase Backup

Write down your seed phrase on paper using clear, permanent ink. Store multiple copies in separate, secure locations. Never store the phrase digitally or photograph it. Verify the backup by re-entering the phrase when prompted. Consider using metal storage for long-term backup.

5

Password Protection

Create a strong password to encrypt your wallet file. This password protects your wallet data but not your Bitcoin - the seed phrase remains the ultimate backup. Use a unique password that you haven't used elsewhere. Consider using a password manager for complex passwords.

6

Server Connection

Electrum will connect to available servers automatically. You can choose specific servers or run your own for enhanced privacy. Consider using Tor for additional anonymity. Verify that your wallet is properly synchronized before making transactions.

Frequently Asked Questions

Is Electrum safe to use?

Electrum is considered one of the safest Bitcoin wallets due to its long track record, open-source development, and robust security features. However, security depends on proper implementation and user practices. Always download from official sources, verify signatures, and follow security best practices for maximum protection.

Does Electrum support other cryptocurrencies besides Bitcoin?

No, Electrum exclusively supports Bitcoin and Bitcoin-related protocols like the Lightning Network. This specialization allows it to optimize for Bitcoin-specific features but requires separate wallets for other cryptocurrencies. Users seeking multi-currency support should consider alternative wallets.

How do I recover my Electrum wallet if I lose my device?

Restore your wallet using your 12-word seed phrase on any device with Electrum installed. Select "Restore from seed" during setup and enter your words in the correct order. If you used a passphrase, enter it when prompted. Test recovery with small amounts first to ensure the process works correctly.

What are Electrum server fees?

Electrum servers typically don't charge fees for basic wallet operations. However, some servers may implement optional fee structures for premium services. Transaction fees (paid to Bitcoin miners) are separate and required for blockchain transactions. Always verify fee structures with your chosen server operator.

How does Electrum's Lightning Network integration work?

Electrum includes native Lightning Network support, allowing you to open payment channels, send/receive Lightning payments, and manage channel liquidity. Lightning transactions are instant and have minimal fees compared to on-chain transactions. However, they require active channel management and online presence.

Can I use Electrum with a hardware wallet?

Yes, Electrum natively supports major hardware wallets including Ledger, Trezor, KeepKey, and Coldcard.
