In today's world, when institutional players trade large blocks of tokenized Real World Assets (RWAs) — such as $5M of tokenized T-Bills — public blockchains broadcast every detail. MEV bots front-run, copy-traders pile on, and slippage costs 2–5% of trade value. In traditional finance, dark pools solve this. On-chain, there is no privacy layer for confidential OTC settlement. Result: The $15T RWA tokenization wave stays stuck because institutions can't trade without broadcasting their intent.
ClawSearch DarkDesk solves this by acting as an AI-brokered OTC dark pool built on iExec Confidential Tokens and the Nox Protocol.
Key Features:
- 🤖 AI Trade Negotiator: ChainGPT Web3 LLM-powered chat for natural-language OTC negotiation.
- 📈 Live RWA Price Oracle: Alpaca API for real-time T-Bill yields and stock prices — zero mocked data.
- 🔒 Confidential Wrap/Unwrap: ERC-20 ↔ cToken conversion via iExec Nox Protocol (ERC-7984 TEE standard).
- 🤝 Confidential Escrow: Atomic swap contract holding both parties' cTokens.
- 🔍 Split-Screen Verifier: Side-by-side: Arbiscan (encrypted) vs. DarkDesk (real balances).
We built the frontend using Next.js 16 and Tailwind CSS v4. The Web3 integration uses wagmi v2 and viem connected to Arbitrum Sepolia. We integrated the ChainGPT API to power the AI negotiator and the Alpaca Markets API for live off-chain oracle data. Our smart contracts are built with Solidity 0.8.28 using the iExec Nox Protocol ERC-7984 (TEE) implementation for Confidential Tokens:
| Package | Version | Purpose |
|---|---|---|
@iexec-nox/nox-confidential-contracts |
0.1.0 | ERC-7984 IERC7984 interface & ERC7984Base |
@iexec-nox/nox-protocol-contracts |
0.2.2 | euint256 encrypted types & Nox SDK |
- [iExec]: We use the Nox Protocol ERC-7984 (TEE) implementation — not OZ/Zama FHE — for Confidential Tokens that hide OTC settlement amounts and balances. Imports
IERC7984andeuint256directly from@iexec-nox/*packages. Seecontracts/DarkDeskEscrow.sol. - [ChainGPT]: We used the ChainGPT Web3 LLM API to build the AI Negotiator that brokers the trade. The implementation can be found in
src/lib/chaingpt.tsandsrc/app/api/chat/route.ts.

Note for Judges: Our front-end runs on
http://localhost:3000. You will need to connect a wallet via RainbowKit. Please ensure you are connected to the Arbitrum Sepolia (Chain ID: 421614) testnet and have Testnet ETH to cover gas for the Escrow.
