Robinwood Stocks Feeds

Chainlink prices the Stock Tokens on Robinhood Chain. Nobody prices the chain natives — the launchpad tokens and Virtuals agents that trade only on the chain's own pools. Robinwood Stocks built this layer because agentic baskets needed it; it runs in production either way, so it is published here as public infrastructure: free, keyless, no token gate.

Read the disclaimer first: these feeds answer in a Chainlink-compatible shape, and shape is not a guarantee. They are operated by Robinwood Stocks on a best-effort basis, with no SLA, no uptime commitment, and no warranty of any kind. If your protocol needs a guaranteed oracle, this is not one.

What a feed is

Every feed is an immutable adapter contract answering latestRoundData() with a USD price at 8 decimals, built from the asset's own on-chain market rather than any off-chain source:

• v4-pooled assets (launchpad tokens, and VIRTUAL itself): the median sqrtPrice over a 3,600-second window of observations recorded in the PoolTwapObserver (at least 6 observations or no answer), dollarized through the quote side's Chainlink feed (USDG/USD or ETH/USD).
• v2-paired assets (Virtuals agents): the pair's own cumulative-price counters, averaged against a permissionless checkpoint aged between 1,800 and 21,600 seconds, then dollarized through the VIRTUAL/USD adapter. If VIRTUAL's own feed is stale, every v2 feed refuses to answer with it.

A time-weighted price is the load-bearing choice: moving it requires holding a pool at a false price for the whole window against arbitrage, not flashing it for one block. What it costs to do that varies enormously per pool — see Honest limits below.

The interface, exactly

The adapters implement only latestRoundData():

function latestRoundData() external view
    returns (uint80 roundId, int256 answer, uint256 startedAt, uint256 updatedAt, uint80 answeredInRound);

Everything else a full Chainlink aggregator exposes does not exist here. Verified against the deployed contracts:

Three return conventions matter more than anything else on this page:

1. updatedAt == 0 means "no price". The window is not honestly covered (too few observations, checkpoint too old or too young). Treat it as the absence of a price and stop; do not read answer.
2. A revert means "no price", not "retry with something else". A stale or dead upstream (the Chainlink quote feed beyond its heartbeat) makes the read revert instead of returning a lie.
3. Freshness is yours to bound. updatedAt tells you when the newest observation landed. The protocol's keeper records observations around the clock (about every five minutes), but nothing guarantees that cadence — apply your own block.timestamp - updatedAt bound on top.

Directory

The canonical directory is the on-chain AssetRegistry at 0x53B255bff87450979c459cC91aFA47A3B93f81fb: assetCount() / assetAt(i) enumerate the assets, assetOf(token) returns the feed. The feed for an asset is frozen at registration and can never be repointed — not by the curator, not by the protocol. The table below is a verified snapshot (2026-07-28); the registry wins over this page, always:

The registry also lists the Stock Tokens (AAPL, MSFT, GOOGL, AMZN, META, NVDA, TSLA, SGOV, SPY), priced by their official Chainlink feeds (8 decimals, 24h heartbeat, 24/5 with US market hours). We point at Chainlink for those and do not wrap or re-serve them.

Honest limits

• Every native feed is currently thin, and we publish the number. Moving VIRTUAL's TWAP by 5% costs on the order of $30k of committed capital; every other native sits under $2k. Per-feed figures are on app.rwoodstocks.xyz/feeds and at /api/feeds/cost; the model is documented in Manipulation cost. Robinwood Stocks's own use is bounded by contract-level turnover and slippage ceilings; an external lending market has no such bound. Do not use these feeds for liquidation or solvency logic.
• The feed is frozen, the market is not. If a canonical pool migrates or its liquidity leaves, the feed keeps reading the old pool. Inside Robinwood Stocks, delisting blocks new buys; an external integrator gets no such protection. Watch the venue you depend on.
• One keeper covers the windows today. Poking is permissionless and anyone can run a keeper (the observer accepts one observation per second per pool; v2 checkpoints are rate-limited to one per minWindow/4), but if the only keeper stops, windows go uncovered and the feeds answer updatedAt = 0 until someone pokes again. That is the designed failure mode: silence, never a stale number dressed as fresh.
