Whisper: The Web3 Messaging Layer

Whisper is a private coordination and execution layer for Web3.

It enables secure communication and value transfer directly between wallets without relying on accounts, profiles, or centralized infrastructure. Whisper is designed for environments where discretion, security, and control are essential.

Whisper replaces traditional identities with cryptographic ones. There are no usernames, passwords, phone numbers, or centralized databases. A Web3 wallet serves as the only identity. Communication occurs directly from wallet to wallet using the XMTP protocol with full end to end encryption. Messages are transmitted off chain. No accounts are created, no profiles exist, and no public identifiers are exposed. Metadata leakage is minimized by design.

Chat in Whisper is not a social feature. It is the execution surface. Within a conversation, two parties can communicate privately, transfer value, and authorize actions using wallet signatures. Payments and approvals are native to the conversation, removing the need to copy addresses, switch interfaces, or rely on external tools.

Each conversation operates through fresh stealth addresses. A user primary wallet is never revealed to counterparties. Payments made inside chat cannot be linked to historical on chain activity. Transactions are routed through relayers using randomized settlement and decoy activity, making attribution from on chain data impractical.

Whisper follows a strict zero trust security model. There is no central server capable of reading, logging, monitoring, or intercepting messages. Every message is encrypted. Every action requires explicit wallet approval. No backend system is trusted with content, identity, or intent.

Whisper does not expose presence signals. There is no last seen status, online indicator, or typing notification. Read receipts can be proven cryptographically without revealing availability or behavioral timing.

There is no public social graph. Whisper has no followers, no public connections, and no visible network effects. Reputation is private and composable. Users can prove successful private interactions without disclosing counterparties or communication details.

Whisper is built for real world coordination where privacy is a requirement, not a feature. This includes funds, founders, DAOs, freelancers, and other high trust participants. Retail usage is a secondary focus.
