People using the wallet in particular are mainly believing in binance. Binance promoted the wallet and even as it's main wallet. Users aren't all smart to understand the differences between wallets, this is why they feel confortable with the most trusted source they think it is. In this case it's binance the giant exchanger in the market. Fortunetly it will cover the loss, but this rises a big red flag about all closed source applications.
Binance must be held accountable for all the problems they cause their clients & this form of responsibility deserves appreciation. After this, people should realize how red flag Binance is & all their centralization products.
I asked Google with keywords: Is trust wallet open source?
Yes, Trust Wallet uses a mix: its core library, Wallet Core, is open-source (C++), but the main mobile apps and browser extension have proprietary elements and, as seen in late 2025, have faced vulnerabilities, leading to strategic code closures for security reasons, making it not fully open-source in the traditional sense, though it leverages open-source tools.
You can see the answer I got from the AI summary, summary makes a convoluted meaning, at the beginning it says that the application is open-source, but at the end of the sentence it says not fully open-source. Dangerous summary for beginners who want to find out factual information about trust wallet.
