Concepts

Robinhood Chain (chain ID 4663) is the blockchain where Robinhood's tokenized equities are issued and settled. Each listed equity is represented by a stock token — an on-chain contract whose balance, price, and corporate-action state can be read directly. HoodGrow indexes those contracts and presents the same facts the chain exposes.

A stock token is an on-chain representation of a listed equity — for example NVDA or AAPL. It is a token contract, not a brokerage account position: it has an address, a total supply, a price feed, and — because equities have corporate actions — an on-chain multiplier that keeps its economic supply correct through splits and similar events.

Every price HoodGrow shows carries a source label, because the price path has two steps:

1. Chainlink (preferred) — USD from the token's Chainlink price feed when it can be resolved and read. These equity feeds generally follow NYSE/Nasdaq hours, so a price carried flat over a weekend is expected.
2. Robinhood registry (fallback) — the official registry price, used when Chainlink is unavailable for that token.

We never blend the two or invent a number from a third-party site. If neither yields a price, the field stays empty.

Robinhood's stock tokens implement ERC-8056. A stock split (or similar action) is reflected as a change to the on-chain uiMultiplier(), not a rewrite of every holder's raw balance. The economic figure is:

A 4-for-1 split leaves totalSupply() unchanged but moves uiMultiplier() from ×1.0 to ×4.0 — so a tool that ignores the multiplier reports a supply four times too small. See the worked example on the About page.

Raw total supply is what the contract returns from a standard supply read. Adjusted supplyapplies the uiMultiplier so the number reflects effective economic supply after corporate actions. HoodGrow prefers the adjusted figure when the multiplier is available and labels whether what you're seeing is corporate-action adjusted.

A pendingaction is a future multiplier already visible on-chain but not yet live — you'll see the current vs. staged value and its effective time. Recentactions come from Robinhood's official ledger (dividends, splits, name changes). Most of the time nothing is staged, and an empty pending list is the correct, honest answer rather than a fabricated one.

24h volume is the USD value that actually traded in a token's Uniswap V3 poolsover the last day. HoodGrow indexes each pool's on-chain Swap events and values every swap by its USDGleg (USDG ≈ $1), so the figure is real USD, not an estimate. It's shown both per pool — so you can see where the flow is — and as a total across pools. A pool with no indexed volume yet reads null, not 0, so “no data yet” stays distinct from “genuinely quiet.”

OHLC candles bucket the price history into open / high / low / close per interval (1h, 4h, 1d) — useful for charting and backtesting. Each candle also carries volumeUsd and swapCountfrom the same swap index, so it's true OHLCV. Volume is nullfor buckets older than the indexer's backfill window. Available via the API's /ohlc endpoint.

TVL — total value locked — is the USD value of assets sitting in a token's Uniswap V3 liquidity pools. It's a rough measure of how deep the market is: higher TVL generally means a given trade moves the price less. HoodGrow shows TVL per pool and as a total.

Some tokens can be supplied to Morpho Blue lending markets to earn yield. The supply APY is read live from Morpho and is variable— it is not promised or paid by HoodGrow, and nothing here is a guaranteed return. When a token isn't a loan asset in any known market, the APY is null (not 0), which is different from a real 0% market.

USDG is the USD-pegged stablecoin (≈ $1, 6 decimals) that most Robinhood Chain stock-token pools trade against. Because one side of each swap is already denominated in dollars, HoodGrow can value trading volume from the USDG leg directly — no external price oracle needed.

The machine API supports x402, an open pay-per-call protocol (USDC on Base): an agent can call an endpoint with no account by attaching a small per-request payment, or use an API key for free access. Prepaid credit bundles are also available. See the API docs for endpoints and pricing.

Pages and the API are served from server-side snapshots refreshed by periodic jobs — registry and token snapshots roughly every 15 minutes, with other jobs on their own schedules — rather than an RPC round-trip on every view. Always read a figure together with its timestamp: “live” means recently snapshotted from the chain and feeds, not recomputed on every click.
