WalletChat

WalletChat turns a wallet address into a messaging address: connect a wallet, sign once, and any address can be reached without email or registration. It ships as a standalone inbox and as a chat widget embedded in dApps, letting counterparties talk inside the page instead of moving to external social apps.

Messages are encrypted client-side and only ciphertext is stored, with decryption keys derived from the two parties' communication keys; the sender proves identity by wallet signature and the recipient verifies the address, so impersonation requires both address and private key. It supports token-gated groups, broadcasts by address list, and attaching context such as order or NFT identifiers to a thread. Threads are filed by address with cross-chain addresses listed in one inbox, and businesses can pipe support conversations into their own back office and route them by tag.
