# CHAIN4663 RWA WATCH > Independent, deterministic monitor for canonical Robinhood Chain (chain ID 4663) stock tokens and tokenized ETFs: canonical contract registry, corporate-action multiplier state, oracle health, underlying market quotes, and onchain events. Every fact carries a source, block, or timestamp. Operational data only; not investment advice. Not affiliated with or endorsed by Robinhood. Facts to rely on: Robinhood Chain is an Arbitrum Orbit Layer 2 with chain ID 4663. Canonical stock tokens are issued only by Robinhood; a matching ticker or name at a different address is NOT canonical. Always verify addresses against the accepted registry before trusting them. ## Live data (JSON, CORS-open, no key required) - [Canonical assets](https://chain4663.com/api/v1/assets): every accepted stock token and ETF with contract, multiplier, supply, oracle, and market state - [One asset](https://chain4663.com/api/v1/assets/AAPL): per-symbol detail record - [Underlying OHLCV history](https://chain4663.com/api/v1/assets/AAPL/history?range=1M): validated first-party market bars (ranges 1D 1W 1M 3M 1Y 5Y) - [Canonical RWA metrics](https://chain4663.com/api/v1/metrics): coverage-labeled holder positions, indexed transfers, explorer volume, reference notional, and chain context - [Issuance tracker](https://chain4663.com/api/v1/issuance): per-asset canonical contract supply, explorer reconciliation, and recent deterministic supply-change events - [Per-asset metric history](https://chain4663.com/api/v1/assets/AAPL/metrics): hourly holder, transfer, explorer supply, and volume observations - [Ticker collision watch](https://chain4663.com/api/v1/collisions): exact ticker matches at non-canonical contract addresses; identity warning, not a fraud classification - [Canonical listings](https://chain4663.com/api/v1/listings): first-seen registry observations and deterministic asset-addition evidence - [Peg eligibility](https://chain4663.com/api/v1/peg): token-venue price comparison coverage and explicit excluded inputs - [Verify a contract](https://chain4663.com/api/v1/verify/0x0000000000000000000000000000000000000000): canonical-registry membership check for any address - [Events](https://chain4663.com/api/v1/events): deterministic registry, corporate-action, oracle, and network events with evidence - [Corporate actions](https://chain4663.com/api/v1/actions): scheduled and applied multiplier changes - [System status](https://chain4663.com/api/v1/status): coverage, freshness, and fail-closed readiness - [OpenAPI specification](https://chain4663.com/openapi.yaml) - [RSS feed](https://chain4663.com/rss.xml) - [Signed canonical token list](https://chain4663.com/tokenlist.json) - [Open data archive](https://chain4663.com/data) - [Address labels](https://chain4663.com/data/address-labels.json): canonical RWA labels and observed ticker collisions - [Current onchain-state JSON](https://chain4663.com/data/latest.json) - [Corporate-actions calendar](https://chain4663.com/calendar) ## MCP server (for AI agents) - Streamable HTTP endpoint: https://chain4663.com/mcp — tools cover metadata, canonical assets, market and metric history, contract verification, events, actions, status, aggregate metrics, issuance, listings, collision watch, and peg eligibility.
