描述
Helix is a programmable treasury operating system for DAOs and onchain businesses. Treasury owners define financial policies as code (e.g. "keep 18 months runway in stablecoins, allocate excess 50% to tokenized SPY, 30% to Aave USDC supply"). An off-chain Execution Agent monitors markets and proposes actions — but never executes. Every proposal is validated on-chain by a Stylus/Rust PolicyEngine that enforces inviolable hard constraints, then requires Safe multisig approval with a timelock before execution. The system covers multi-asset custody (stablecoins, DeFi positions, tokenized RWAs via Robinhood Chain), jurisdiction-aware tax accounting (FIFO/LIFO/HIFO), and produces a fully verifiable audit trail for every treasury action.
本次黑客松进展
Designed full system architecture with STRIDE threat model, 9 named security invariants, and 8 technical docs (~3,000 lines)
Built and deployed 14 Solidity smart contracts on Arbitrum Sepolia: TreasuryVault, PolicyRegistry (7-day timelock), ProposalRegistry (bond + slash mechanics), TaxEngine, OracleAggregator (Chainlink + Pyth + deviation guard), TreasuryFactory, 4 asset adapters (ERC20/Aave/Pendle/RobinhoodRWA), HelixSafeModule
Built PolicyEngine in Rust targeting Arbitrum Stylus (WASM): hard constraint evaluation (runway floor, max single asset, daily movement cap, whitelist/blacklist, emergency brake), policy bytecode decoder, action simulator, 6 modules with 32 unit tests
Built Execution Agent in TypeScript: MarketMonitor (vault event subscription), Simulator (eth_call dry-runs), ProposalBuilder (wallet signing + on-chain submission), PolicyEvaluator, Reporter (Discord/Slack with LLM-generated summaries), LLMProvider (Anthropic/OpenAI for NL-to-DSL policy translation)
Built SDK (@helix-treasury/sdk): HelixClient with policy management, proposal lifecycle, tax report export
Deployed 9 contracts to Arbitrum Sepolia with 94 on-chain transactions (deposits, withdrawals, emergency drills, config updates). Mock token suite (mUSDC, mWETH, mARB, mSPY, mTBILL) with live vault holdings
Integrated Robinhood Chain testnet: RWA adapter for tokenized equities, CorporateActionListener for dividends/splits/mergers
CI pipeline: Foundry tests (33 passing, 10,000 fuzz runs), Rust build + clippy + tests, TypeScript build + tests, Slither static analysis, TruffleHog secret scan, ABI export
融资状态
Not yet fundraised / Bootstrap. Solo builder, self-funded during buildathon. Seeking pre-seed after mainnet audit (target Q3 2026). Open to grants from Arbitrum Foundation, Robinhood Chain ecosystem fund, or strategic angels with treasury/DeFi infrastructure experience.
