Verified domains
A project proves domain control with a DNS TXT record, then links approved email senders to that domain.
For projects and DAOs
Stop your users getting phished by people pretending to be you.
Post3 gives your project a verifiable mailbox channel, so members can see sender and action proof before they trust an announcement, payment request, governance notice, or claim.

The project identity checks passed.
Project announcements in group chats and social DMs can be copied in seconds. Users often have no reliable way to tell whether a message is actually from the team, especially when it asks them to sign, claim, vote, or send funds. Post3 fixes that by attaching project identity and wallet-origin proof to the message itself.
Project identity
Prove the sender before the user has to decide.
Post3 connects a project, its domains, its wallets, its senders, and its contracts into one visible trust story.
Wallet binding
A project wallet can be bound through a current-wallet challenge, name-service record, Safe owner check, or contract ownership signal.
Sender registration
Approved project senders can carry the same identity context instead of looking like random email addresses.
Verified payout wallets
Payment requests can show whether the payee wallet matches the signer or a wallet already verified for your project.
Concrete scenario
A DAO sends a treasury notification and members can verify it.
The message arrives in members' wallet inboxes with the proof beside it, not hidden in a blog post or pasted in chat.
The DAO sends the notification from a verified project wallet.
Members receive it at their wallet addresses, even if they have not opened Post3 before.
The trust panel shows the signer owns the contract and the payout wallet matches.
A fake message cannot produce the same proof, so guessing stops.
Treasury notification
verified DAO message
signed by contract owner
The wallet that signed this notice controls the DAO treasury contract. The payee wallet also matches the signed action.
Verified calls to action
Your mint, vote, claim, or payment request should carry proof.
Users are trained to distrust links in chat. Post3 moves the call to action into a wallet mailbox with sender identity and action proof beside it.

How verification works
The checks are plain proof, not vibes.
A project proves control over the things users already recognize: a domain, a wallet, and a contract.
Domain
Add a Post3 TXT record to DNS so the inbox can show that the sender controls the domain.
Wallet
Sign a challenge or publish a matching record so the project wallet can be tied to the project.
Contract
Post3 checks ownership or role signals so messages can show a relationship to the contract users care about.
