X PrimeFlow Stock Token Verifier

Problem. On Robinhood Chain, a ticker proves nothing: a scan of the chain on 20 September 2026 (chain explorer: https://robinhoodchain.blockscout.com; our catalogue and method: https://xprimeflow.trade/robinhood-chain) found 286 contracts presenting as Stock Tokens, and 92 of them were look-alikes, including a second NVDA and a second GME at other addresses. Stock Tokens also do not rebase: dividends and splits move a per-token multiplier, so the price of one underlying share is the token price divided by that multiplier. Users who research the chain have to jump between an explorer, token lists and market tools to get this right.

What we built. A single public, read-only page for Robinhood Chain (chain ID 4663):

- Stock Token catalogue: the 194 genuine tokens identified by contract bytecode hash and deployer address, never by name, each with its live corporate-action multiplier;

- network pulse: block height and block time, gas, and ETH escrowed on Ethereum L1, read from our own Ethereum node;

- market context: perpetual markets on Lighter and Chainlink price feeds for the same underlyings, plus aggregator quotes shown as quotes only;

- a keyless read-only API behind every number, with source and freshness shown for each section;

- open source: the verification rule, the registry snapshot, a command-line verifier, a library and the read-only API are published under Apache-2.0 at https://github.com/BonyNode/stock-token-verifier (data terms in DATA.md).

Built during the event window. The Robinhood Chain integration, the authenticity checks, the public dashboard and its API were built in September 2026 (first commits on 20 September). The open-source repository is a clean extraction of that module, published on 28 September 2026 as a single commit; a dated commit log is available to judges on request. X PrimeFlow is not affiliated with, endorsed by, or officially connected with Robinhood Markets, Inc. The page uses the issuer's term "Stock Tokens" and never describes them as share ownership.

Why Arbitrum. Robinhood Chain is an Arbitrum chain; the dashboard makes its on-chain information easier to inspect and verify.

No smart contract is deployed by our team: this is a data and tooling product.
