Mostro has implemented a new end-to-end encrypted chat for its Bitcoin P2P exchanges, designed to resolve disputes without compromising user privacy. Using advanced cryptography (DHEC), each transaction generates a unique *shared master key* known only to the buyer and seller. In case of a dispute, either party can voluntarily hand over this key to a mediator, allowing them to decrypt and review only that specific conversation, which is unalterable and cannot be deleted by scammers. This innovative feature ensures the availability of verifiable evidence for fair resolution, avoiding the need for centralized message storage and protecting the overall privacy of communications on Mostro.

All of this aims to provide a privacy-focused, user-friendly peer-to-peer exchange platform, supported by HRF, Opensats, and other contributors.
