CrypTalk

CrypTalk is a wallet-to-wallet encrypted messaging and trading platform where users connect by address rather than phone number or email, serving privacy-conscious traders, DAOs and buyers of high-value physical goods. Conventional messengers require an identity handle, keep chat logs and trading intent on platform servers, and make phishing and impersonation hard to distinguish.

Messaging runs on XMTP with end-to-end encryption between clients and wallet signatures for authentication. Files and asset documents sit in Filecoin, and the chat window supports price checks, transfers and escrowed trades; an integrated model flags scam scripts and suspicious links. On the physical-asset side, escrow contracts and on-chain reputation accumulate trade history per address, and high-value items can be split into transferable shares.
