The Proof-of-Stake Inbox.

Eradicate spam fundamentally. Unverified senders must stake crypto to reach you. If it's spam, they are slashed. If it's real, it's free. Welcome to Web3 Email.

Anti-Spam Economics

Spammers can't afford to send millions of emails if every connection requires a micro-transaction. You slash the stakes of bots, earning the protocol fee.

Escrow Yield Generation

While emails sit in the quarantine queue awaiting your approval, their associated Web3 stakes generate Aave yield directly into your protocol treasury.

Global Consensus Reputation

Every slash event modifies a sender's on-chain reputation score. Our enterprise API feeds this decentralized trust ledger directly to B2B security products.
