Sui Overflow 2026PTB Atomic PaymentsAES 256

Pay, chat, and settle
in rooms that self-destruct

Encrypted
Client-side only

AES-GCM 256. The key is forged in your browser, never uploaded, and dies with the room.

Programmable
PTB-atomic payments

Tip, paid DM, subscription, or invoice — every Sui transfer is bundled atomically with its encrypted message.

Ephemeral
Self-destruct

Closing the room emits an on-chain event. Every client wipes its key. Only undecryptable bytes remain.

How It Works

Encrypt
Transact
Expire

Stripe meets Signal, on Sui. Tip, subscribe, negotiate, or invoice inside an encrypted room — every Sui transfer is PTB-atomic with its encrypted message. Close the room and the key is gone forever. Even if the ciphertext survives on IPFS, no one can decrypt it. No decrypt.

Why Now

Sui just clicked the missing pieces into place. Seal shipped to mainnet — native onchain encryption. Paired with USDsui, the consumer surface is finally here.

Seal — encryption native to Sui

Identity-based encryption with threshold cryptography. Define a policy on-chain; ciphertext only opens when the policy passes. SoSui sits at the intersection — Seal upgrades the invite envelope into a consumer-facing surface.

USDsui — gasless stablecoin

Stripe-issued stablecoin with protocol-level gas abstraction. Tip, subscribe, and settle in dollars without ever holding SUI. Phase 3 makes this the default settlement rail in SoSui.
