You define which server(s) to use to receive the messages, your contacts — the servers you use to send the messages to them. Every conversation is likely to use two different servers. This design prevents leaking any users' metadata on the application level. To further improve privacy and protect your IP address you can connect to messaging servers via Tor. Only client devices store user profiles, contacts and groups; the messages are sent with 2-layer e2e encryption.Starting Price: Free -

Solarium
Solarium
Solarium is a fully decentralised, end-to-end encrypted, censorship-resistant instant messenger based on the Solana blockchain. Solarium is currently in alpha phase, running on the Solana devnet. All messages in Solarium are end-to-end encrypted using the XChaCha20-Poly1305 symmetric encryption algorithm, using a 256-bit content encryption key (CEK) that is shared for all messages in a given channel. The message content in Solarium is not directly signed, i.e. the data itself, once decrypted, does not contain details about the sender. Instead, the blockchain transaction that adds the message to the channel is signed by the sender. -
