Cake Wallet is a U.S. company. Its developer is Cake Labs Inc., which is based in Wyoming, United States. The official website states that Cake Wallet was founded in 2018.

Cake's one serious incident deserves specifics, not a soft clause. Versions before v4.1.7 generated 12-word Electrum-style Segwit Bitcoin wallets from a weak random-number generator, producing keys with far too little entropy — few enough that attackers could brute-force them. The flaw was disclosed in May 2021 and patched in v4.1.7. Later research by the Milk Sad team traced about 548.9 BTC flowing through 8,757 weak wallets between 2020 and 2024, with the later drains mostly malicious sweeps of stragglers who never moved their coins. Two facts frame it fairly. Monero wallets were never affected — the bug lived only in the Bitcoin key path. And the fix shipped five years ago, with no comparable incident since. It stays in this review because a wallet that once shipped a key-generation flaw owes readers the scale, the fix, and the lesson: move funds off any Bitcoin wallet created in Cake before v4.1.7 if you somehow still have one.

Cake Labs LLC is a US company registered in Orlando, Florida, founded by Vikrant Sharma. That is worth stating plainly, because it separates Cake Wallet from the anonymous-team wallets that dominate the privacy niche. The wallet shipped in 2018 as the first Monero wallet on iOS, has run for eight years without interruption, and reports around 1.75 million users. A named founder, a US business registration, and a public GitHub repo are exactly the trust signals a self-custody user should demand before trusting an app with seed generation, and Cake clears all three. The product itself is one thing, cleanly. There is no exchange attached, no custodial account tier, no token, and no rename history. You download the app, it generates keys on your device, and Cake never holds your funds.

Generally speaking, the longer the wavelength and the lower the frequency, the less an electromagnetic wave is scattered, the stronger its ability to diffract, and the farther it can usually travel. Therefore, red light generally travels farther than blue light, and lower-frequency electromagnetic waves generally propagate more easily than higher-frequency electromagnetic waves.

Higher-frequency waves attenuate more easily, while lower-frequency waves travel farther.

Light and radio waves are both electromagnetic waves, made up of mutually perpendicular, time-varying electric and magnetic fields. Both can travel through a vacuum at the speed of light, approximately 3×10^8 meters per second. Both can undergo reflection, refraction, diffraction, interference, and polarization, and both can carry energy and information. Visible light has wavelengths of about 380 to 750 nanometers. It has a high frequency and relatively high energy, and it can be detected by the human eye. Radio waves have longer wavelengths, lower frequencies, and lower energy per photon. They are commonly used for communication, broadcasting, and radar. They are fundamentally the same type of wave. The main differences are their wavelength, frequency, and photon energy. The formulas are: c = fλ E = hf

Escaping centralized platforms

Once or twice security issues pop up, the relationship is over—just delete them permanently. 🗑️ If someone lacks basic privacy awareness, they fundamentally don't care about your safety. ⚠️ How could a person like that not stab you in the back when it counts? Keeping someone like this around is a total disaster. 💣

I finally understand why Japan is a society where men tend to have a slightly higher status, hahaha. I’ve seen so many Japanese people...

There’s nothing wrong with not having AI. If I can’t subscribe, then I simply won’t. I built the code by modifying it bit by bit, and I can still get things done on my own. 💪 No matter how much technology advances, having one more Bitcoin feels more practical. In many cases, building financial wealth is more useful than technological progress. 💰 After all, the high-tech industry seems to be obsessed with monopolies. If they want to monopolize things, so be it—it’s really no big deal. 😌

“I don’t care about the privacy of my communications” is basically the same as saying, “I don’t care about your safety.” When someone says that, they’re telling you that your safety doesn’t matter to them. Just block them.
