Blockscan Chat

Blockscan Chat is a wallet-to-wallet messaging tool from the Etherscan team that addresses the missing communication layer in on-chain interaction by letting address holders talk directly. Messages travel off-chain with end-to-end encryption, covering both EVM and Solana address systems. The product ships a mobile app and IDM identity management, caps accounts at 50 sessions, and allows only addresses with a nonce above zero to start conversations to block spam. Once an identity is bound to an Ethereum address it can be reused across sessions, and messages arrive through mobile notifications; conversation lists support quick search by address notes, with unread badges on the app icon.

The tool integrates deeply with the Etherscan explorer so counterparties can start a conversation inside the block browser without switching apps. It runs in public beta, with sessions and identity features open, and message records are kept only on local and recipient devices.
