描述
CorpAction Engine is a Corporate Action Oracle + Execution Engine for tokenized equities on Robinhood Chain (Arbitrum Orbit L2). It solves the corporate action synchronization problem for RWAs — when real stocks experience dividends, splits, mergers, or delistings, every action needs an on-chain counterpart that executes in sync, or the token diverges from reality. The engine monitors SEC EDGAR, DTCC ISO 20022, and financial data APIs, normalizes events into standardized ActionIntent structs, validates through multi-sig quorum, and executes on-chain via 6 specialized executor contracts. It supports 10 corporate action types (dividends via Merkle-based USDC distribution, forward/reverse splits via ERC-8056 UI multiplier, cash/stock/hybrid mergers with election mechanism, spinoffs, 5-phase delistings with dispute/rollback, and ticker migrations), covering 500+ US equities. The system includes 14 smart contracts, a TypeScript SDK, off-chain ingestion/processor/validator services, and cross-chain broadcasting via LayerZero V2.
本次黑客松进展
Designed and implemented 14 Solidity smart contracts (3 core, 6 executors, 2 integrations, 1 attestation, 1 fee collector, 3 libraries) with full deployment on Robinhood Chain Testnet (Chain ID 46630)
Built 3 off-chain TypeScript services: data ingestion (SEC EDGAR + DTCC + Polygon.io + EOD Historical), event processor with AI-powered hybrid classification (rule engine + Claude Sonnet 4 fallback), and multi-sig validator node
Developed a TypeScript SDK (@corpaction/sdk) with 12 granular event subscriptions, typed parameter decoding, and batch claim support
Wrote 127+ tests (unit, integration, invariant, scenario, fuzz) achieving 94.2% code coverage, including real-world replays of AAPL dividend, NVDA 10:1 split, TWTR delisting, FB→META ticker change, and AT&T/WBD spinoff
Executed 7 live corporate actions on testnet with verified on-chain state transitions, Merkle-based claims, and EIP-712 attestations
Built full observability stack with Prometheus alerting (10 rules), Grafana dashboards (11 panels), and structured logging
Created interactive demo site (https://2mxhf668.mule.page/) with 16 functional panels including action proposal form, lifecycle simulator, fee calculator, Merkle tree builder/verifier, split multiplier calculator, quorum simulator, and delisting phase simulator
Designed PostgreSQL schema (11 tables) and Docker Compose stack for production deployment
