Two sources. One sweep.
Watch the feeds
diverge.
Feedspire sweeps two independent public price sources — a Solana DEX-aggregator spot mark and a perp venue mid — and lights up the spread between them in basis points, with a staleness clock that flashes when a source goes quiet. The prices are live and keyless. Nothing here is traded, custodied, minted or signed.
Read-only concept. Marks are live from Jupiter (Solana spot) and Hyperliquid (perp mids) — two independent public sources, not a claim about any specific oracle's internal health. The divergence and staleness are client-observed. Not financial advice.
Your wallet
You, read-only
A read-only view of your connected wallet, read live from the chain through a same-origin RPC. Feedspire never requests a transaction or a signature — it only reads public on-chain data.
The divergence board
Spot mark vs perp mid
For each coin, the Solana spot mark (Jupiter) sits beside the perp mid (Hyperliquid). The spread between them is shown in basis points, and each source carries its own staleness clock — the seconds since this browser last pulled a fresh value for it. When a source stops answering, its clock keeps ticking and flashes.
Pointing the beam at the feeds…
These are two independent public sources — a Solana DEX-aggregator price and a perp venue mid — quoted in slightly different instruments, so a non-zero spread is normal and is not a claim that any specific oracle is wrong or unhealthy. Staleness is client-observed freshness of this browser's own polling, not a source's published heartbeat. Any row whose spot mint returns no price is marked SAMPLE rather than faked. Not financial advice.
The perp floor
Live perp mids
A live read of the busiest Hyperliquid perpetual markets — mark price, 24-hour move and notional volume — sorted by volume. This is the venue the watchtower reads its perp mids from, shown in full.
| # | Market | Mark | 24h | Funding | Volume 24h |

Live from Hyperliquid's public info endpoint, keyless. Mark price, 24-hour change, funding and notional volume are the venue's own figures. Not financial advice.
Under the hood
How the sweep works
Four steps, every price a real call to a public, keyless endpoint. The only modelled parts — the spread math and the staleness clock — are plain arithmetic on live values, shown in the open.
-
01
Pull the spot marks
Feedspire asks Jupiter for the Solana USD price of each coin's spot token — SOL, a wrapped BTC and a wrapped ETH. These are DEX-aggregator marks.
…
-
02
Pull the perp mids
It asks Hyperliquid for every perp's mid price in one call, then matches each coin's symbol to its mid — an independent venue, independent instrument.
…

03
Measure the spread
Spread in basis points is simply
(spot − perp) / perp × 10000. Positive is a spot premium; negative is a spot discount. Nothing is smoothed.…

04
Clock the staleness
Each source carries a clock: seconds since this browser last got a fresh value for it. If a source goes quiet, the clock climbs and the row flashes.

Questions
Is this telling me an oracle is broken?
No. Feedspire watches two independent public price sources — a Solana DEX-aggregator spot mark and a perp venue mid — and shows the gap between them. A spread is normal: they are different venues quoting slightly different instruments. It is not a claim about any specific oracle's internal health, heartbeat or correctness.
What does the staleness clock actually measure?
It is client-observed freshness: the number of seconds since this browser last received a fresh value for that source. It is not a source's published update interval. If your connection or the endpoint hiccups, the clock climbs and flashes — that tells you the watchtower's own view has gone stale, not necessarily the source.
Where do the prices come from?
Spot marks come from Jupiter's public price API for Solana tokens (SOL, a wrapped BTC, a wrapped ETH). Perp mids come from Hyperliquid's public info endpoint. Both are keyless and read directly in your browser. If a coin's spot mint returns no price, that row is marked SAMPLE instead of being faked.
Can I trade or settle anything here?
No. Feedspire is read-only. There is no order, no custody, nothing is minted, and the wallet connect only reads public data — it never asks you to sign or send a transaction.
Do you collect anything about me?
No accounts, no tracking and no cookies. Everything runs in your browser against public APIs and a same-origin read-only RPC.
What this is, plainly
Feedspire is a read-only concept that puts two independent public price sources side by side and measures the gap. The marks are live and keyless; the divergence math and the staleness clock are transparent client-side arithmetic, clearly labelled. Nothing here connects a wallet for signing, places a trade, holds funds or mints a coin. Divergence and staleness are client-observed. Not financial advice.
