XNDU
Xanadu Quantum • Robinhood Token
Pools
README
Xanadu Quantum is a Robinhood Chain stock token — an upgradeable BeaconProxy (ERC-20, 18 decimals) sharing one Stock implementation with every other Robinhood stock token.
It doesn't have a Chainlink price feed yet, so there's no live price to show. The contract, holders, and any pools are indexed live here; a price will appear the moment a feed is deployed.
Read the price
// Read XNDU correctly on Robinhood Chain (chain 4663). ethers v6.import { ethers } from "ethers";
const provider = new ethers.JsonRpcProvider(RPC);
const feed = new ethers.Contract(
"0x… (no feed yet)",
["function latestRoundData() view returns (uint80,int256,uint256,uint256,uint80)",
"function decimals() view returns (uint8)"],
provider
);
// price = stock × uiMultiplier already — do NOT multiply again
const dec = await feed.decimals();
const rd = await feed.latestRoundData();
const priceUSD = Number(ethers.formatUnits(rd.answer, dec));
// the real guard: reject a stale answer (feed is 24/5, market-aware)
const now = (await provider.getBlock("latest")).timestamp;
const stale = Number(now) - Number(rd.updatedAt) > 6*3600;
// NOTE: do NOT gate on the L2 sequencer feed — it's hardwired to 'down' here.Or just fetch the record
No RPC, no ABIs, no guard logic — gitstock already resolved and guarded everything.
// No RPC or ABIs needed — fetch the whole resolved record.
const r = await fetch("https://gitstock.io/XNDU/stock.json");
const s = await r.json();
s.price.usd // live price (already stock × multiplier)
s.holders // holder count
s.tvlUsd // pool TVL in USD
s.dependents // tokens paired against XNDU
s.feed.proxy // the Chainlink proxy gitstock reads
s.fieldNotes // the quirks that break integrationsField notes — what the docs don't tell you
No feed for XNDU yet
No Chainlink feed is deployed for this token yet, so there's no live price. The universal Robinhood-stock-token quirks below still apply the moment one appears.
The price feed is not on the token
The Stock token carries no price and no feed pointer on-chain — no latestRoundData(), no priceFeed(). The Chainlink feed is a separate, unlinked contract, and the token→feed mapping isn't published anywhere. gitstock resolves it for you (verified via the token factory's own creation events, not by symbol).
⚠ The L2 sequencer gate is hardwired to “down”
Robinhood ships a custom SequencerGate whose source() is currently the zero address — so latestRoundData() returns answer = 1 (down) forever, while the price feeds are healthy. Copy the standard Chainlink pattern require(sequencerUp == 0) and your app will never render a price here. Read the gate for transparency, but don't hard-gate on it yet.
Staleness is the real guard — and it's market-aware
Because the sequencer gate is unusable, freshness on the feed itself is the actual safety check. During US market hours the feed updates every ~17min–1h on deviation; off-hours it slows to a few hours but keeps moving (24/5). A single tight threshold false-flags overnight reads. Weekend-flat is normal, not stale.
Feed price is the TOKEN price, not the stock price
latestRoundData() already returns stock_price × uiMultiplier() — don't apply the multiplier again. Dividends reinvest through the multiplier, so the token tracks total return and drifts above the headline stock price over time. That's why the number here won't match Google Finance.
oraclePaused() is advisory, not enforced
During corporate actions the token oracle is paused. oraclePaused() == true means “price temporarily unavailable”, not zero/error — and it isn't enforced on-chain, so a paused oracle can still return a value. Treat it as a display state; rely on staleness for protection.
Read decimals() on-chain; don't hardcode
Feed answers use the feed's own decimals (8 for these USD feeds). Read decimals() from the proxy every time rather than assuming.
