Crypto-sender

Crypto-sender is a decentralized messenger - using the TON blockchain. Since this service is also a cryptocurrency wallet, you can send cryptocurrency transfers in addition to messages to your contacts. There is no single server or infrastructure - the application connects to any server TON network. All data is distributed across the blockchain network among millions of computers. Turning off the Internet in a separate country and even on a separate continent will not affect the network’s performance.

Using the developed libraries, quite quickly, create smart contracts of any complexity for Android and Windows.

Decentralization

• Decentralized messenger is independent of states, corporations and developers.

• TON blockchain belongs to users.

• No one can control, block, deactivate, restrict or censor accounts.

• Private keys never leave your device.

• The sequence of messages and their reliability is guaranteed by the blockchain.

Spam blocking

You can block any unwanted contact at any time and not waste time on annoying interlocutors, the blocking procedure is extremely simplified. The contacts you blocked in Crypto-sender cannot send you messages, etc. If someone from the “black list” needs to be unblocked, then simply find the desired contact in the list, open the menu with a long tap and press “Remove from black list” in it.
   

Message encryption

Crypto-sender allows you to achieve privacy while communicating using a mobile device. All sent messages are encrypted. The sender encrypts his message with the public key of the recipient, the recipient decrypts the message with his private key.

Private & Public

In a private smart-contract, only users from your list can send messages to you. In a public smart-contract, you can receive messages from all users of the messenger, even not included in your list.
