This is an ordinary hot wallet in the form of a web service. It has a nice interface and works quickly. You can store up to 15 cryptocurrencies on various blockchains (such as BTC, ETH, TRX, TON, and others), as well as manage rubles. To work with fiat, you need to go through verification (standard KYC using a passport). The wallet can be topped up in both cryptocurrency and fiat (for example, via transfer through the SBP or by card number). After that, you can convert fiat to crypto, send tokens to other users (both within ExWallet and across the entire blockchain), pay for various services, and so on.
