BTC DefiLlama delays app release to eliminate counterfeit apps
DefiLlama's anonymous founder 0xngmi said on August 15 that the platform delayed the public release of its mobile apps while trying to remove apps that fake its DeFi analytics platform from Apple's App Store.
Summary
founder 0xngmi said DefiLlama delayed the release of its mobile app until the fake App Store list was removed. After DefiLlama demonstrated that a counterfeit app could steal cryptocurrency funds, Apple removed it within days. DefiLlama's official iPhone app is now online, and Apple has listed DEFILLAMA LIMITED as a provider. Apple's guidelines prohibit apps from impersonating and using other developers 'brands or product names without authorization. Counterfeit cryptocurrency apps have appeared in the Apple Store multiple times, including recent cases of Ledger and Sparrow wallets.
Based on his post, the team finally demonstrated that a fake app could empty a cryptocurrency wallet with funds before Apple removed it. 0xngmi said DefiLlama had been reporting the app to Apple for months about trademark and impersonation issues, but failed to successfully remove it. The team then injected a small amount of money into a test wallet, downloaded the app, and watched the money disappear. "Within a few days, the app was removed from shelves," he wrote. The amount stolen from the test wallet was not disclosed.
"We have been trying to remove a fake DefiLlama app from the Apple Store for months, informing Apple of trademark infringement, counterfeiting, etc... Then we loaded a small wallet, downloaded the app, cleared as expected, and reported it to Apple. Within a few days, the app was removed."-- 0xngmi (@0xngmi) August 15, 2026
DefiLlama waits for counterfeit apps to be removed
Security issues have directly affected DefiLlama's product launch. 0xngmi said the company "waited until all counterfeit apps were removed before launching our apps to avoid any users being deceived." This timeline is a unilateral statement made by DefiLlama and has not been independently confirmed by Apple. The real DefiLlama app is now publicly released. DefiLlama's official page shows that its mobile products are already available on iOS and Android. Apple's list identifies the iPhone app as "DefiLlama: DeFi Tracker," lists DefiLlama as a developer, and lists DEFILLAMA LIMITED as a provider.
At the same time, Apple's App Review guidelines prohibit apps that impersonate other apps or services. The rules also prohibit developers from using other developers 'icons, brands or product names without permission. Repeated impersonation may lead to removal from Apple's developer program. In official materials reviewed in this report, Apple has not publicly responded to 0xngmi's specific claims. The company has previously said its App Review system evaluates the security and reliability of apps, and Apple reported that it rejected more than 320,000 submissions in 2024 because they copied other apps, constituted spam, or otherwise misled users.
Counterfeit cryptocurrency apps have caused losses
Before the DefiLlama incident, other counterfeit cryptocurrency apps appeared on the Apple market. In April, a fraudulent Ledger Live app reportedly stole 5.9 BTC (approximately $420,000) from musician Garrett Dutton. On-chain researcher ZachXBT traced the stolen Bitcoin to an address associated with KuCoin. Apple is also facing a U.S. lawsuit in which three users claim a counterfeit Sparrow wallet app caused $1.835 million in Bitcoin losses. The allegations have not yet been tested in court. Apple said in the case that it had removed the fake app and terminated the relevant developer accounts. In addition, a fake Phantom wallet app also appeared on the Apple App Store and was removed after users reported losses.
Subsequent development
DefiLlama's official app is now online, and its website provides direct access to genuine mobile products. The iOS list currently displays version 1.0.5 and identifies defillama.com as a developer's website, providing users with multiple verification details before installing. The founders have not disclosed the attacker's address, the amount stolen during DefiLlama's testing, or the technical analysis of the malicious application. These details are necessary to independently recreate the wallet theft process. For users, the most reliable verification guarantee is to access mobile apps through the official DefiLlama website and confirm the developers and providers on the list, rather than relying solely on the App Store search results.
