End-to-end encryption (E2EE) is a method of data protection in which information is encrypted on the sender's side and decrypted only on the recipient's side. This means that even if the data is intercepted during transmission, it remains inaccessible to third parties, including service providers and the messenger itself.

In the context of messengers, end-to-end encryption provides a high level of privacy and security for conversations, as only the participants have access to the decrypted messages. This protects against unauthorized access, including potential attacks by hackers or government agencies.

Multiple identities is a feature that allows users to create and manage several profiles within one messenger. This is useful for separating personal and professional life, as well as for maintaining privacy in different communication contexts, since each identity has its own profile, settings, and contacts.

Since no information about the number of identities is stored anywhere, users can create as many profiles as they need without restrictions. The PIN code used to switch between identities is the only way to access each of them, and any of the PIN codes can be used to activate an identity, so it is impossible to determine which one is valid.

Built-in payments is a feature that allows users to send and receive money directly in the messenger, without the need to use third-party apps or services. This simplifies the process of financial transactions, making it more convenient and faster.

Payments are made using cryptocurrency, which provides a high level of security and privacy. Users can easily send money to their contacts, pay for goods and services, and receive funds from other users without leaving the messenger or sharing their bank account or credit card details.

Signed documents and assets is a feature that allows users to create, send, and sign legally significant documents directly in the messenger. This may include contracts, agreements, financial documents, and other important papers that require signatures from the parties involved.

Businesses can also use this feature to send documents and assets to clients, such as tickets, vouchers, or certificates. Document signing is carried out using cryptographic methods, ensuring their legal force and protection against forgery.
