If you dabble in crypto, dropping a few dollars here and a few dollars there, you might not be too concerned about security yet. But before you know it, you're holding onto a pretty penny in the form of BitcoinEthereum, and other cryptos—making sure your crypto is extra safe becomes top priority.

Here are the top five, why crypto investors love them, and which coins they support.

There are lots of factors to consider when locking up your crypto safely, from whether to keep your coins on a crypto exchange vs wallet to what type of crypto wallet to use. Once you've upgraded to keeping your crypto off of exchanges and in safe crypto wallets, it's time to start thinking about using an open-source crypto wallet. Here's why and where you can find the best ones.

What is an open-source crypto wallet?

crypto wallet is a software or hardware wallet where you can store the public and private keys that give you access to your cryptocurrency. When software is open source, that means its original code is freely available for anyone to view, change, and redistribute. Therefore, an open-source crypto wallet is a crypto wallet that makes its source code that users can fork to customize and add additional layers of security. 


Open-source crypto wallets are attractive to people who invest in crypto heavily because, without access to the source code running their wallet, investors can't verify for themselves that their crypto is being kept safe and secure. Open-source projects in crypto, from open-source wallets to open-source dApps and DeFi coins, offer ultimate transparency and decentralization.

Is there an open-source multi-crypto wallet?

Virtually all open-source crypto wallets that currently exist are designed for one specific cryptocurrency. For example, there are open-source Bitcoin wallets and open-source Ethereum wallets, but not many open-source Bitcoin wallets can hold both BTC and Ether (ETH).


AirGap Wallet was recently released as one of the first fully open-source wallets to support multiple crypto coins. It's a two-device, cold storage wallet that's completely open source and offers staking. It currently supports 8 cryptocurrencies: Bitcoin (BTC), Ether (ETH), Tezos (XTZ), Aeternity (AE), Polkadot (DOT), Kusama (KSM), Cosmos (ATOM), and Groestlcoin (GRS).

Exodus is a popular option, but it's not completely open-source. They publish open-source code for many but not all of their wallet's components. In particular, they keep their design and user interface code private so that scammers can't duplicate their wallet. That said, Exodus wallets support 150+ crypto coins, so it's definitely a more convenient option for folks who don't want a different wallet for each coin.

Best open source crypto wallets

When it comes to the best fully open source crypto wallets, here are the top five, why crypto investors love them, and which coins they support.

1. Electrum

One of the most established and widely used open-source crypto wallets, Electrum is a fairly user-friendly Bitcoin wallet. You can set up their desktop wallet with cold storage for additional security, but you'll need a second, offline device such as an old smartphone or laptop. Electrum is fast and can be used on desktop and mobile or with various hardware wallets.

2. Mycelium

Mycelium is another one of the most popular open-source crypto wallets, and it's also a Bitcoin wallet. It's completely decentralized, and it's been around since 2013. This mobile wallet is well known for its security—in addition to being open source, it's reproducible and supports hardware wallets and cold storage.

3. MyEtherWallet

If it's Ether you're investing in, MyEtherWallet (MEW) is one of the best open-source Ethereum wallets. This free open-source crypto wallet lets you generate wallets and complete transactions on the Ethereum blockchain. It supports ETH and ERC20 tokens. This web-based wallet also supports integration with popular hardware wallets and you can use it to invest in DeFi.

4. Copay

Copay is a convenient open-source Bitcoin wallet. You can store multiple different wallets within the same app on Copay, and the Copay app (available on iOS and Android as well as Windows, Mac, and Linux) has a clean, user-friendly interface. Wallets include multi-signature security, and your keys are stored offline.

5. Blockstream Green

Blockstream Green, formerly known as Green Address, is an open-source Bitcoin wallet available on iOS, Android, and desktop computers. It's one of the most simplistic and easy-to-use open-source crypto wallets, and for added security, it uses a multi-signature shield and doesn't require KYC. It also integrates with a number of different hardware wallets.

Do I need an open-source DeFi wallet?

Having your own digital wallets is more secure, but it's definitely not necessary to self-store your private keys. These days, accessing DeFi applications on Coinbase, Kraken, and numerous other centralized exchanges is easy. That means you can buy Ethereum with fiat and start trading it right away on Uniswap or other popular decentralized exchanges.

Even Crypto.com and other crypto platforms have added support for NFTs, so you can invest in your favorite generative art projects like LetsWalk or Nouns NFTs. They're custodial wallets, which means they use universal digital wallet infrastructure to let you securely access your digital assets on any device anywhere in the world.
