Cool Wallet Go: Safe Crypto Storage After the Atomic Wallet Hack

Cool Wallet Go: Safer Crypto Storage Without the Stress

I've been reading about the Atomic Wallet hack and it shook me a bit. Up to $100M in user tokens got drained from that hot wallet. A Cool Wallet Go setup blends cold storage with on-the-go trading so you don't need a crypto PhD to stay safe. After that mess, I think isolated hardware or a Cool Wallet Go that mixes cold and hot in one app is the move.

The short story is simple. Atomic Wallet said less than 1% of its active monthly users got hit, about 50,000 people. But the total loss was big, between $35M and $100M. That's real money gone from regular folks. I don't want that to be me, and you probably don't either.

What Happened to Atomic Wallet

Atomic Wallet is an Estonian software wallet. It claims 5 million users and supports over 500 tokens. You can buy, sell, stake, and convert crypto inside the app. Then a hack cleared many holdings altogether. The company wrote they don't store or access user private keys, which made the root cause hard to find.

A blockchain audit firm called Least Authority warned in February 2023 that Atomic Wallet users were at risk. They found flawed cryptography, bad docs, and wrong use of the Electron framework. A few months later, a suspected state-sponsored group drained the funds. Some estimates put total loss near $100M.

The wallet's security team speculated that the cause could be a virus on user devices, man-in-the-middle attack, infrastructure breach, or malware code injection.

Why Hot Wallets Are Risky

Hot wallets stay connected to the internet. That makes them easy to use but also easy to hit. Phishing and hacks mutate daily, and some are state-sponsored by groups like Lazarus from North Korea. The Atomic Wallet breach is one more sign that hot storage is not great for long-term hold.

The U.S. Federal Trade Commission warned about a phishing campaign hitting MetaMask and PayPal users. In the first half of 2023, a hacker took $10M in Ethereum from OG crypto users. The threats are real and they keep changing. I'd rather not bet my savings on a hot wallet alone.

Common attack types on hot wallets

What Are Crypto Cold Wallets

If you self-custody and want to play it safe, a hardware wallet is the base layer. what are crypto cold wallets is a fair question. They are devices that keep your private keys offline, away from online danger. A cold wallet does not talk to the web unless you plug it in or tap it on purpose.

Cold storage is not new. CoolWallet launched its first hardware wallet in 2014 and has secured user funds for years. The idea is simple: keys stay on the device, not on a server. That alone cuts most hack paths down to near zero.

A hardware wallet is a cold storage solution that stores users' private keys offline, away from the dangers of hacks and heists caused by online activity.

Examples of Cold Wallets in Crypto

There are a bunch of devices out there. examples of cold wallets in crypto include CoolWallet Pro, CoolWallet S, and other brands people talk about. CoolWallet Pro has an EAL6+ secure element and military-grade Bluetooth encryption. It is wafer-thin and easy to carry without drawing eyes.

The CoolWallet App gives safe Web3 hot and cold storage in one place. You own your keys at all times. If you want to use cold storage but also trade on the go, their setup lets you do both without stress. The two wallet modules live in one app but stay isolated from each other.

How the Atomic Wallet Hack Was Traced

Atomic Wallet worked with Chainalysis and Crystal to look at the stolen funds. Some loot moved through mixing services. Elliptic traced funds to Sinbad.io, a mixer tied to Lazarus Group. That group also hit Axie Infinity for $540M and Horizon Bridge for $100M in past events.

Sinbad.io is a new form of Blender.io, a mixer under U.S. sanctions. The link to North Korea is strong. It is still not clear if affected users will get reimbursed. I hate that part - people lost funds and no clear refund path exists.

Lazarus Group, North Korea's notoriously successful state-sponsored hacking group, is believed to be behind the Atomic Wallet hack.

Lessons From the Atomic Wallet Breach

The hack showed weak spots in hot wallets. It also showed why cold wallets are the way for long-term storage. Hackers keep finding new attack paths. If white hat hackers flag a flaw, like Least Authority did, you should listen and act fast.

A repo with open firmware helps too. CoolWallet is open-sourcing its hardware wallet firmware for review. That builds trust through transparency. For me, seeing code open is a big plus when picking a device.

What we can learn

Best Secure Crypto Wallet Choices

If you want to self-custody, just use a reputable hardware wallet with a proven track record. Look for extra safety like a secure element. best secure crypto wallet for most people is one that is easy but keeps keys offline. CoolWallet Pro fits that for many users.

CoolWallet App now has a custom hot wallet free to download. You can move funds from hot to cold and back as you need. It also gives access to airdrops. The brand calls it combining hot and cold to cool down your worries about self-custody. I like that plain way of putting it.

Best Hotwallet Use With Cold Storage

You don't need to pick only one type. best hotwallet in my view is the free CoolWallet App module used with their hardware. You keep cold storage for most funds and hot for small trades. That cuts your risk but keeps you moving.

The two modules are isolated in the app. So a hit on the hot side does not open the cold side. That split is the whole point of a Cool Wallet Go style setup. Trade on the go, sleep at night.

Other wallets people mention

CoolWallet App Hot and Cold in One

CoolWallet's App gives reliable Web3 hot and cold storage. You get full ownership of assets at all times. Want cold but also trade on the go? Or just use a hot wallet with hardware as backup? The app covers both without making you a tech wizard.

The Pro model has a $149 list price and is built for DeFi, NFT, and Web3 users. It is thin and quiet in your pocket. Bluetooth is encrypted. For me, the mix of mobility and a secure element is the sell.

Why Atomic Wallet Points to Cold Storage

The Atomic Wallet hack points to danger of online wallets with weak support. Users who store for a long time should use cold storage or a mix of cold and hot. That is the plain takeaway from the breach.

I don't think every hot wallet is bad. But for hold, cold is calm. A Cool Wallet Go setup lets you keep cold storage and still trade on the go. No stress, no expert kit needed. That's the kind of simple I can get behind.

Signs you should switch to cold

Download CoolWallet App and open the free hot wallet. Write your seed on paper, not a screen shot. Test a small send in. Then if you can, buy a CoolWallet Pro and move most funds there. Keep a little in hot for trades.

The app shows both modules and you swipe between them. They stay separate. That is the core of a Cool Wallet Go setup. I like that it does not force you to pick one camp. You get both, safe and easy.
