Roadmap

What works today, what is being built next, and where this is going. Grouped by readiness rather than by date.

Everything below is grouped by how close it is to your hands, not by a calendar. We would rather ship something that holds than hit a date with something that does not.

Available now

Capability
Encrypted messaging
Sealed in your browser, carried as ciphertext, opened only by the recipient.
Live
Names you own
Minted to your wallet. No renewal, no rent, no operator who can reassign them.
Live
Gas-only mail
Bodies ride in event logs. Names of five characters and up cost nothing beyond the transaction.
Live
Stamps
Charge strangers to reach you. Answer them and it goes back; ignore them and it becomes yours.
Live
Contacts and blocking
Time-bounded free passes, and a block that returns any stamp being held.
Live
Key rotation
Retire a key without losing older mail. Versions are monotonic and never reset.
Live
Reserved names
Brand and system names held back so they cannot be used to impersonate.

Coming next

Specified and under way. These are the ones we expect to land first.

Independent security audit

In progress

Outside review of both contracts and the client key derivation. Three rounds of adversarial review have been done in house and found real issues. That is the argument for external eyes, not a substitute for them. The report will be published here in full, findings included.

Provable authorship

Coming soon

Today a message proves it was not tampered with, and the chain records who paid for the transaction. A per-account signing key would make authorship provable on its own terms, independent of who sent it.

opBNB

Coming soon

The same protocol on the cheaper chain, so routine messaging costs a fraction of a cent. One mailbox identity already spans both networks by design; what remains is how names resolve across them.

Envelope v3

Coming soon

A move to XChaCha20-Poly1305. The format carries a version byte precisely so this is a clean upgrade: clients keep opening older mail indefinitely.

On the horizon

Intended, not yet specified. Listed so you know where this is going.

Private by default

Contents are already private; the social graph is not. Stealth addressing and sealed sender would close the largest remaining gap, so observers cannot see who is talking to whom.

Attachments

Large files held off chain, with only a reference and a content key inside the envelope. The on-chain size ceiling stays where it is.

Encrypted broadcast

Announcements to many recipients at once, without a plaintext mailing list sitting somewhere waiting to leak.

Tradeable names

Premium names as transferable assets, with a primary market rather than a race between whoever is watching the mempool.

Mobile

A dedicated client. The web app already works on a phone; this is about doing it properly.

Name interoperability

Resolving existing on-chain identities, so a name you already own can point at a mailbox.
