Email you own. Spam you don’t pay for.
A decentralized mail protocol on Solana — postage paid by the sender and earned by you, pricing spam out at the source; addresses tied to your wallet instead of a rented domain; and mail encrypted end-to-end and stored off-chain on IPFS. Standard SMTP, IMAP, and POP3 underneath, so the inbox you already use just works.
Spam becomes unprofitable, not just harder
Every message costs the sender real SOL, priced by you. Strangers pay a default rate; senders you trust can send for free. Filters guess at spam forever — pricing ends it at the source.
Get paid for your own inbox
Postage from strangers lands directly in your wallet. You’re compensated for the attention you’re already spending defending it, instead of a provider monetizing your data for free.
Turn your inbox into an opt-in income stream
Opt into the campaign pool and advertisers pay you — postage to land in your inbox, and a bounty when you reply. You pick the topics you’ll hear about; nobody reaches you uninvited or for free.
An address that’s actually yours
Tied to your wallet, not a domain someone else controls. Move it to a new domain any time and keep your history and identity intact — nobody can revoke it out from under you.
Private by default
Every message is sealed straight to your wallet and stored on IPFS, not on a company’s server. No provider ever holds your mail in the clear.
Works with the inbox you already use
Standard SMTP, IMAP, and POP3 to the letter — your existing mail client just works. No new app to learn, no migration required.
No gatekeeper, no single company
SithBit is a protocol, not a product. Anyone who owns a domain can run a mail server and earn a share of the mail it carries — the same footing as every other operator on the network.
