Solchat is a communication protocol built on the Solana blockchain, designed to facilitate text, voice, and video communications. It operates within a Web3 environment, leveraging the blockchain's capabilities to offer services analogous to those found in traditional Web2 platforms. The protocol utilises Solana's low transaction fees (gas fees) and has the capability to store messages and group chat data on-chain, ensuring that interactions are recorded within the blockchain.

Solchat is used to provide encrypted communication services in a decentralised manner. The platform supports text messaging, voice calls, and video calls, aiming to replicate the functionality of conventional communication applications but with the added benefits of blockchain technology. This includes enhanced privacy and security, with encryption applied to interactions and the use of peer-to-peer connections for audio and video calls through WebRTC technology.
