ROFL.DAM
ROFL.DAM Is a Web3-enabled chat platform running on OASIS ROFL where users can create or join groups, chat via a Nostr relay, and manage group membership with help from MongoDB
ROFL.DAM (Runtime Off-chain Logic Decentralized Authenticated Messaging) solves key problems of traditional chat platforms by giving users full control, privacy, and resilience through decentralization.

Testament
Last will and testament for crypto holders. Keep your will private while you're alive. After you're deceased, beneficiaries can claim their share.

P.I.M.P.
Public prediction markets leak alpha the moment a trade appears in the mempool. Bots and fast‑followers watch every order, jump the queue, and extract value that should belong to the trader.
Private Insight Market Protocol (PIMP) fixes that leak. Built on Oasis Sapphire’s confidential EVM, PIMP encrypts every bet at the wallet, stores only a hash on‑chain, and keeps trade details sealed inside Sapphire’s TEE until settlement.

ChainLab Grid
ChainLab Grid's mission is to make computing resources accessible via decentralized crowdfunding of compute power, securely validated and aggregated by our TEE, powered by Oasis.

ZK-Pal
On-ramps/Off-ramps system using Paypal

RØPE
Trust-minimized on/offramp solution deployed as an MCP server. No KYC, no middleman, no payment verification risk. Just verifiable execution with ROFL & private data handling via OPL.

Pasanaku
Pasanaku is a community based savings and credit system through rotation. In a round-robin, every month a different member receives CRC deposits from all other members.

HealthTrust
HealthTrust turns sensitive health records into a self‑sovereign, privacy‑preserving data asset that patients can safely monetize.
Users connect their wearables once, retain full control over who accesses their data, and earn tokens whenever it fuels valuable research.

Activist Toolkit
A decentralized, privacy-first protocol to empower activists, protect their identities, and preserve immutable proof of protest — even under repressive regimes.
Built using Oasis Sapphire and ROFL, Activist Toolkit provides censorship-resistant infrastructure to verify presence, coordinate emergency alerts, and resist digital erasure without exposing user identities.

Shield Wallet
Shield Wallet is a POC of a next-generation multisignature meta-transaction design.
It is simple but robust in its core and includes many features that have been designed by analyzing the current vulnerabilities in Gnosis Safe that led to attacks like the Bybit one.
