A DIFFERENT KIND OF CONNECTION
Your social life,
held in your hand.
Your identity is a key on your device. Your posts and messages start there, too. Mentos connects you directly when it can; relays help when it can’t.
You decide what stays. Someone else can keep a copy only when you allow it and they accept.
Know how sharing works. A source needs to be online for content to travel, unless someone has been allowed to keep a copy.
THE CONNECTION UNDERNEATH
Phone to phone.
Powered by iroh.
Mentos uses iroh to connect devices over encrypted QUIC connections. It tries a direct path first, with public n0 relays helping when the devices can’t connect directly.
Explore iroh.computerDirect when possible.
Hole punching helps devices find each other across networks. A relay provides a fallback path.
Relays carry encrypted traffic.
They don’t keep your Mentos account or store your posts and messages.
Choose your connection mode.
Use direct connections, relay-only mode, or Tor through a locally configured Orbot proxy.

CRYPTO & THE MNT WALLET
Your keys. Your transactions.
Send and receive Mentos (MNT), view transaction history, and track funds held in escrow. Signed account chains are shared between phones on the network.
MENTOS WALLET•••••• MNT
SendReceiveEscrow
MNT is the app’s own ledger asset, not a Bitcoin or Ethereum wallet. Network partitions can disagree; confirmations are not irreversible guarantees.
How the ledger worksTHE PEER-TO-PEER MARKETPLACE
A market between people.
Buy and sell goods, post paid tasks, trade MNT, or offer spare storage and compute. Signed listings travel across the network.
ShopTasksExchangeResourcesAdsPlugins
Order and task payments use escrow, with acceptance, release, refund, and dispute flows. Reviews are tied to completed trades.

Under the hoodCryptography starts with your identity.
An Ed25519 key identifies you and signs what you create. A 24-word recovery phrase restores that identity. The app encrypts its local database, and groups and spaces use shared encryption keys.

THE DETAILS MAKE IT YOURS
More than a place to talk.
Everyday social features, with controls
for the data and devices behind them.
Messages with a delivery trail
Direct messages use a durable queue for each recipient. Mentos distinguishes sending from delivery: an authenticated acknowledgement confirms arrival, and a separate receipt can confirm that it was read.
A little more detail
Pin, mute, archive, and organize conversations into folders. Group invitations are accepted before keys are shared; removing a member rotates the group key.
Calls, streams, and live sharing
Voice and video calls use their own media transport. Mentos also includes live streaming and live location sharing inside conversations.
A little more detail
Call media is accepted only from peers registered for that call. Real-time sharing depends on the participating devices being reachable.
Posts, stories, and communities
Publish posts, share stories, save drafts, and bookmark content. Spaces bring channels and forums together, while broadcasts let people subscribe to an author.
A little more detail
Public spaces can be discovered through marketplace directory listings. Posts are available from an online source or a device that has agreed to keep a copy.
Files with explicit custody
Manage transfers and inspect who holds what. Your content, content you agreed to keep, and temporary live content are treated differently.
A little more detail
Storage leases encrypt files on the renter’s phone. The provider receives ciphertext without the key, and periodic possession checks control escrow payouts.
Put spare capacity to work
Offer storage or a supported compute task through the marketplace. Device checks measure CPU throughput, memory, free storage, disk speeds, and network conditions.
A little more detail
Compute jobs use a fixed menu: compression, photo resizing and compression, and proof-of-work stamps. The renter verifies results before releasing payment; submitted files are not executed as code.
An identity you can take with you
Create an identity without an email address or phone number. Switch between local identities, protect access with a PIN, inspect stored data, and export your information.
A little more detail
The 24-word recovery phrase restores the identity key. Recovering the key alone does not recover every locally stored message or file; keep a data backup as well.

WHAT PROTECTS WHAT
Privacy in layers.
Identity, transport, storage, and sharing
each have a different job.
Ed25519 signatures
Your public key is your user ID and iroh endpoint identity. Signed envelopes preserve the author’s exact payload; recipients verify signatures and permissions before accepting it.
Ed25519 · BIP39Sealed group traffic
XChaCha20-Poly1305 seals shared group and space payloads. Membership controls who receives a key, and keys rotate when members leave.
XChaCha20-Poly1305Encryption on the device
The local database is encrypted. The file-encryption helper uses chunked AES-256-GCM with a fresh key per file; SHA-256 identifies and verifies transferred blobs.
AES-256-GCM · SHA-256Where content lives matters.
Mentos does not have a central archive. Availability depends on reachable devices and the copies people consent to keep.
- Owned
- Created on this device, stored locally, and served to peers.
- Kept
- Another person allowed a copy, and this device accepted it.
- Live
- Temporary content in memory, dropped when no source is reachable.
A FEW THINGS TO KNOW
Open about
how it works.
What happens when someone is offline?
Two devices exchange data while both are reachable. A permitted keeper can provide a copy when the author is away. There is no central store-and-forward service; a queued message waits for a suitable connection.
Does peer-to-peer mean there are no relays?
No. Direct UDP paths are tried where possible. The public n0 relays help establish connections and carry encrypted traffic where needed. They do not host your Mentos account or archive your content.
What does a wallet confirmation mean?
Accepted means this phone counts the entry. Witnessed means another phone has voted for it. Final means the app’s witness threshold is met without a competing entry; Conflicted signals a competing entry. These are ledger states, not a guarantee of irreversible settlement. Disconnected parts of the network can disagree.
Read the ledger rules ↗Can I hide my IP address from peers?
Standard mode allows direct connections. Relay-only mode avoids exposing a direct device address to peers. Tor mode uses relay-only networking with a configured local HTTP CONNECT proxy such as Orbot. Each mode has different connection and performance tradeoffs.
What does a recovery phrase restore?
The phrase restores the same signing identity. Messages, media, and other local content need a separate backup or an available authorized copy. Identity recovery and content recovery are different.
