Electrum Wallet Guide for Bitcoin Casino Players

Electrum is a free, open-source Bitcoin-only wallet for Windows, macOS, Linux and Android. It has been around since November 2011, gives you full control over transaction fees and coin selection, and works with most hardware wallets. For casino players who deposit and withdraw in BTC, it is one of the most precise tools available, but it supports no other coins and has no iPhone app.

This guide covers Electrum as of October 2026 (current version 4.8.2, released 11 September 2026): what it does, how to install it without falling for fake downloads, how its seed works, what fees you pay, and how to move BTC to and from a crypto casino.

What is Electrum?

Thomas Voegtlin created Electrum in November 2011. It is distributed under the MIT licence, and its binaries are reproducible and signed by several developers, so anyone can check that the download matches the published source code.

Electrum is a “light” wallet. Rather than downloading the whole Bitcoin blockchain, it connects to Electrum servers and verifies your transactions with Simple Payment Verification (SPV). Your private keys are encrypted and never leave your computer; the Electrum FAQ states that the client never sends private keys to the servers. Servers can, however, see your IP address and which addresses belong to your wallet, which is a privacy trade-off. Advanced users can run their own server to remove it.

The project describes itself plainly: Electrum only supports Bitcoin and has never supported altcoins. Any “Electrum” app offering Ethereum, Litecoin or tokens is a different product or a fake.

Pros and cons for casino players

How to install Electrum safely

Fake versions are the biggest risk with Electrum, so installation deserves care.

1. Download only from electrum.org. Type the address yourself. Do not follow links from ads, forums, search ads or in-app messages.
2. Verify the signature. Electrum publishes GPG signatures for its binaries. The FAQ recommends verifying them, which lets you ignore false antivirus warnings with confidence and catches tampered files.
3. Install on a clean device. A computer with malware or remote-access tools can steal a hot wallet no matter how good the software is.
4. Android: use the official listing linked from electrum.org. The current Android app (rebuilt on QML in version 4.4.0, April 2023) needs Android 8.0 or later.

History shows why this matters. From late December 2018, attackers added malicious servers to the Electrum network that showed older clients a fake “update required” message linking to malware. Malwarebytes reported that the campaign stole more than 771 BTC. The developers patched the flaw and the network has changed since, but the lesson stands: Electrum never needs you to download an update from a pop-up.

Creating a wallet and understanding the seed

1. Open Electrum and choose a wallet name.
2. Pick “Standard wallet” (other options are two-factor, multi-signature and import).
3. Select “Create a new seed”. Electrum shows a seed phrase, by default 12 words.
4. Write the words on paper in order and store them offline. Then retype the seed to confirm.
5. Set a strong password. This encrypts the wallet file on that device.

Two points catch people out. First, the password cannot be recovered. The Electrum FAQ says you can restore from the seed and set a new password, but if you lose both, there is no way to recover the money.

Second, Electrum seeds are not BIP39 seeds. Electrum’s documentation explains that its seed phrases include a version number that tells the software which derivation to follow, and that Electrum does not generate BIP39 seeds. In practice this means an Electrum seed may not restore in another wallet such as MetaMask or a phone wallet. Electrum can restore BIP39 phrases from other wallets, and version 4.0.3 (September 2020) added automated BIP39 recovery that scans the common derivation paths.

New standard wallets use native SegWit addresses starting with “bc1”, the default since Electrum 3.3.0 in December 2018. SegWit transactions take up less block space than older address types, which lowers fees.

Electrum fees explained

Electrum itself charges nothing. Every Bitcoin transaction pays a miner fee, and Electrum lets you choose it. Fees are priced per unit of transaction size (satoshis per virtual byte), not per amount sent, so sending 0.001 BTC and 1 BTC from a single input costs about the same.

The FAQ explains that recent versions use “dynamic fees”, taking estimates from servers so your fee suits current demand. You can also set the fee by hand on the send screen. Three tools make Electrum strong here:

• Fee slider. Choose between a target based on mempool depth or estimated confirmation time, or type a fixed rate.
• Replace-by-fee (RBF). If a deposit sits unconfirmed because the fee was too low, right-click it in History and choose “Increase fee”.
• Child-pays-for-parent (CPFP). When you receive a stuck transaction, for example a slow casino withdrawal, you can spend its output with a high fee to pull both into a block.

A short worked example: a typical one-input, two-output native SegWit payment is roughly 140 virtual bytes. At 5 sat/vB that is about 700 satoshis (0.000007 BTC); at 50 sat/vB it is about 7,000 satoshis (0.00007 BTC). Combining many small inputs, such as lots of small casino withdrawals, makes a transaction larger and the fee higher. Coin control (View, Show Coins) lets you pick which inputs to spend.

Bitcoin aims for one block about every ten minutes on average, so a deposit with a competitive fee usually gets its first confirmation within that sort of window, but busy periods can take much longer. Casinos decide how many confirmations they need before crediting you.

Lightning in Electrum

Electrum added experimental Lightning Network support in version 4.0.1 (July 2020) and trampoline routing in 4.1.0 (March 2021), which lets a light client delegate path-finding instead of downloading the network graph. Later versions added submarine swaps (moving funds between on-chain and Lightning) and, from 4.6.0 (July 2025), the use of Nostr to find swap providers.

Lightning payments are near-instant and cheap, but you have to open a channel first, and backups work differently from an on-chain wallet. Version 4.8.0 (July 2026) fixed channel backups for certain channel types, which is a reminder that Lightning in Electrum is still evolving. For casino deposits, use Lightning only if the cashier explicitly lists a Lightning option and you understand channel management. Most casino cashiers we track list on-chain BTC.

Using Electrum at a Bitcoin casino

Depositing BTC from Electrum

1. In the casino cashier, choose Bitcoin (BTC). If several networks are offered, choose the native Bitcoin network, not a wrapped token on BEP-20 or ERC-20.
2. Copy the deposit address. Paste it into Electrum’s “Pay to” field and check the first and last characters against the cashier.
3. Enter the amount. Check that it meets the casino’s minimum deposit after fees.
4. Set the fee. If you want to play soon, use a rate the slider shows as confirming in the next block or two. Leave RBF on so you can bump it later.
5. Click Pay, enter your password (or confirm on your hardware wallet) and send.
6. Watch the transaction in History. The casino credits the balance after its own confirmation rule.

Some casinos generate a fresh deposit address each time. Always copy the current address from the cashier rather than reusing an old one from Electrum’s contacts.

Withdrawing back to Electrum

Open the Receive tab, create a request and copy the bc1 address. Paste it into the casino’s withdrawal form and choose the Bitcoin network. Casinos set their own minimums, limits and processing times, and many apply identity checks before a first or large withdrawal under their terms. Our reviews list the operator-stated numbers, for example the 7Bit Casino review and the mBit Casino review.

Electrum’s labels help with record-keeping. Tag each deposit and withdrawal with the casino’s name, so you can see your net result per site and, where your country taxes crypto disposals, have the data you need.

Is Electrum safe?

Electrum’s design is sound: private keys stay encrypted on your device, transactions are verified by SPV, the code is open, and builds are reproducible. The release notes show a steady run of security updates; 4.7.0 (January 2026) through 4.8.2 (September 2026) are each labelled as security updates. Keep it updated from electrum.org only.

Most losses come from the user side:

• Downloading a fake Electrum from a search ad or a pop-up.
• Entering a seed into a “recovery” or “validation” website.
• Malware on the computer that swaps copied addresses or reads the wallet file.
• Losing the seed and forgetting the password at the same time.

Two features reduce those risks. With a hardware wallet such as a Trezor, Electrum builds the transaction but the device signs it, so keys never touch the computer. Electrum 4.8.0 added support for the Trezor Safe 7. A watch-only wallet, made from your public key, can show balances and create receive addresses on an everyday computer while signing happens elsewhere. See our Trezor guide for that setup.

Two-factor wallets work through TrustedCoin, a third-party co-signing service. They add protection against a stolen computer but bring their own dependency and terms, so read them before you choose that option.

Electrum vs other wallets for gambling

If you deposit in ETH or USDT as well as BTC, pair Electrum with our MetaMask guide, or compare more options in the software wallet guide. The crypto wallet hub explains hot versus cold storage.

Getting bitcoin into Electrum

Electrum does not sell bitcoin. Buy BTC on an exchange that is licensed or registered where you live, then withdraw it to an Electrum receive address. Exchanges charge their own withdrawal fee, which can be higher than the network fee itself, so compare it before you choose. Our exchange guide covers the main platforms. For the casino side, our Bitcoin casino guide lists the sites we have checked and their current offers.

Whatever wallet you use, keep your gambling budget separate from savings and use the casino’s own deposit limits. Our responsible gambling page lists where to get help.

Electrum in summary

Electrum is a mature, free and open-source Bitcoin wallet that gives casino players unusual control over fees and transactions. It suits BTC-only players on desktop or Android who are happy with a technical interface. It is the wrong choice if you need ETH or stablecoins, or if you only use an iPhone. Download it only from electrum.org, back up the Electrum seed knowing it is not BIP39, keep RBF on for deposits, and use a hardware wallet for anything you are not about to play with.

Electrum FAQ

Is Electrum wallet safe?

Electrum is open source, keeps private keys encrypted on your device and has run since 2011. Most losses come from fake downloads, phishing and malware, so download only from electrum.org, verify the signature and consider a hardware wallet.

Is Electrum good for Bitcoin casinos?

Yes, for BTC. You can set the fee for each deposit, bump a stuck one with replace-by-fee and label transactions by casino. It does not support any coin other than Bitcoin.

Does Electrum charge fees?

No. Electrum charges no fee of its own. You pay the Bitcoin network fee, which you can set yourself, and the casino or exchange may charge its own withdrawal fees.

Is Electrum available on iPhone?

No. Electrum is available for Windows, macOS, Linux and Android 8.0 or later. There is no official iOS app, so treat any Electrum app in the App Store with suspicion.

Can I restore an Electrum seed in another wallet?

Often not. Electrum uses its own versioned seed format and does not generate BIP39 seeds, so many other wallets cannot read it. Electrum itself can restore BIP39 phrases made elsewhere.

Can I buy bitcoin with Electrum?

No. Electrum is only a wallet. Buy bitcoin on an exchange and withdraw it to an Electrum receive address.
