Proposal: Canton-native Privacy-First Perpetual Futures Exchange

Development Fund Proposal Submission

Proposal file: /proposals/canton_hexa_dex.md

---

Summary

Hexa DEX is a privacy-first perpetual futures exchange built natively on Canton Network. It is the first on-chain derivatives venue to keep orders fully encrypted until settlement, eliminating MEV, frontrunning, and stop-loss hunting via an AWS Nitro Enclave matching engine with Frequent Batch Auctions, with all settlement committed to Canton smart contracts. This proposal requests 1,000,000 CC across three milestones to complete and launch a production system supporting BTC/USD, ETH/USD, SOL/USD, and CC/USD perpetual markets on Canton MainNet.

Notes for Reviewers

• Prior Canton work: Shipped TruthOracle, a live prediction market on Canton TestNet bridging Kalshi institutional liquidity with Canton settlement. Direct production experience with Daml contracts, the Ledger API, and on-chain event architecture.
• 4+ months of existing development: A working trading application, published whitepaper, and full system architecture are already complete. Links in the proposal header.
• Champion: Currently seeking a Tech & Ops Committee champion. Happy to connect with any committee member for a technical walkthrough.
• Security audit: Budgeted as part of Milestone 3 before mainnet deployment. All critical/high findings will be resolved prior to M3 disbursement.
• Open-source outputs: All five Daml contracts (M1) and the Market Maker SDK (M2) will be released under Apache 2.0.
• CC/USD market: In addition to the standard BTC/USD, ETH/USD, SOL/USD markets, Hexa launches with a CC/USD perpetual to create native Canton ecosystem utility.
