Whispr

Connect any wallet — or generate one with an email — and your address becomes your identity. No username, no password, no sign-up form; one signature activates your private inbox.

Message any registered wallet one-to-one or start a group with as many members as you want. Only the people inside a conversation can read it, and new messages arrive live.

Share images, video, audio and documents that open directly in the chat and stay private to that conversation, with 1 GB of storage per user.

Write one message, add up to ten wallet addresses, and deliver it everywhere with a single wallet signature. Each recipient receives it in their own thread.

Attach ETH or USDC to a message and let the recipient claim it with one tap. There is no gas cost to send or claim USDC, and nobody else can see who received the funds.

Your wallet signs each request, the app's relayer submits it, and a paymaster contract covers the gas, so chatting costs 0 ETH.
