Public Roadmap · v0.1

From encrypted rooms to programmable private payments
on Sui.

Stripe × Signal, on Sui. Five phases turning PTB-atomic transfers + AES-256 ephemeral rooms into the privacy layer for tipping, subscriptions, OTC negotiation, and private invoicing. Phase 2 is our Sui Overflow 2026 submission — DeFi & Payments core track.

PHASE 01

Foundation — Encrypted Ephemeral Rooms

shipped

Ship the privacy-and-self-destruct primitive that every later payment phase composes on.

Timeline: Shipped on testnet

Core features

Pay SUI to create a room — tiered: free (public) / 0.01 SUI (private)
Per-room AES-256 key generated client-side; private rooms are true E2E via invite envelope
Public rooms encrypted-at-rest with on-chain key sharing (any visitor can join — disclosed, not blanket E2E)
Messages encrypted client-side → pinned to IPFS (Pinata) → CID committed to a Sui shared object
TTL enforced on-chain: 7d public, 30d private; per-room message cap (1000) with paginated UI
Live polling subscription (5s) — new messages render across devices
Two-step destruct: owner flips room to Closed → can then burn_room_key to zero the on-chain key (Burned); clients wipe local key on RoomClosed event
Chain is source of truth — frontend pulls room list + history from Sui, not localStorage
Upgradeable Sui Move package via AdminCap (already migrated Config v1 → v2, Room v1 → v4)

▲ Live on testnet. Package 0xc991…3cda. Config v2 + Room v4 deployed, public/private + TTL + cap all enforced on-chain. Next: PTB-native micropayments + atomic payment memos (Sui Overflow 2026).

PHASE 02

Programmable Private Payments

in progress

Turn rooms into atomic payment channels. PTB binds SUI transfer + encrypted memo + on-chain commit in one tx — programmable money meets ephemeral privacy.

Timeline: Sui Overflow 2026 submission · deadline 2026-06-21

Core features

PTB-native micropayment — atomic send message + transfer SUI in one tx, no two-step approve
Tip-a-message — recipient gets SUI atomically with the message commit; receipt is non-repudiable on-chain
Paid DM rooms — per-message fee, sender pays per send (creator paid-DM model)
Encrypted payment memo — attach AES-256 encrypted note to any SUI transfer; only counterparty decrypts
Auto fee split — room creation fee atomically splits room owner + protocol treasury via PTB
Mainnet deployment path — Sui mainnet config + Pinata production blob backend (50% prize gated on mainnet)

PHASE 03

Account Abstraction & Recurring Payments

next up

Kill signature fatigue. Stack Sui's native AA primitives — zkLogin, sponsored transactions, session keys, and USDsui gasless transfer — so users tip, subscribe, and stream payments without seeing a wallet popup after the first session approval.

Timeline: 4 – 6 weeks after Phase 2

Core features

USDsui gasless transfer — pay and receive in Stripe-issued stablecoin with no SUI required on the user side; gas handled at the protocol level
zkLogin onboarding — sign up with Google / Apple OAuth, no seed phrase, ed25519 keypair derived from the OIDC claim
Sui sponsored transactions — gas station (sui-gas-pool / Shinami) pays SUI gas for add_message and tip txs
Session keys — one wallet popup per room session generates an ephemeral signer scoped to that room
Per-session and per-room spending caps to bound sponsorship cost and abuse
Subscription rooms — monthly USDsui auto-debit via session-key delegation; auto-expire if unpaid
SUI / USDsui streaming payroll — continuous per-second transfer, room as payroll dashboard
Graceful fallback to user-paid mode when relayer is down or session revoked

PHASE 04

Token Economy & DAO

planned

Token flywheel — pay for rooms with $SOSUI at discount, stake to earn free-room allowances, protocol fees buy-back-and-burn.

Timeline: 4 – 6 weeks after Phase 3

Core features

Launch $SOSUI (Sui Coin standard) — fair launch, fixed supply
Pay for rooms with $SOSUI at a discount, or stake to unlock free public rooms
Protocol fees auto buy-back & burn $SOSUI
Token-gated VIP rooms (hold N $SOSUI to enter)
DAO governance — vote on fees, TTL, message cap, treasury allocation
Treasury auto-allocation between protocol reserve / LP / buyback

PHASE 05

Scale & Agent Economy

future

Sui-native decentralized storage + threshold key management, mobile onboarding, and x402-powered API monetization for the AI agent economy.

Timeline: 8 – 12 weeks after Phase 4 (rolling)

Core features

Migrate ciphertext storage Pinata → Walrus (Sui-native decentralized blob)
Seal integration — on-chain access control + threshold key management
x402 protocol integration — HTTP 402 payment-required gating on /api endpoints, AI agents pay-per-request in SUI or USDsui
AI-assisted features priced via x402 — chat summary, live translation, cover art, per-room agent memory
Mobile app (React Native) with push notifications and encrypted offline cache
Public dashboard with privacy-friendly on-chain analytics
Cross-chain bridge in — non-Sui users pay into Sui rooms via Wormhole / native bridges
