How many floors
does your trade
climb?
Quietfloor asks Jupiter for real quotes at five sizes — $100 to $100,000 — and draws the result as a building section: buys climb the floors above the spot price, sells descend into the basement. The quiet floor is the biggest trade that barely moves the price.

The depth ladder
Type a ticker or paste a mint. Quotes are fetched one at a time (about one every 1.6 seconds) to respect Jupiter's public rate limit — the drawing builds as they arrive.

Step height = the larger of Jupiter's price impact and the all-in cost vs spot, on a square-root scale so small and large values both stay readable.

Some quotes came back busy (Jupiter's free API is rate-limited).
"Impact" is Jupiter's reported price impact for that quote. "All-in vs spot" compares what you'd receive with Jupiter's spot price and so also includes pool fees and any token transfer fee — small negatives just mean the route beat the reference price.

Method of survey
Four steps, each one a real public request.
Identify
Jupiter's token search turns a ticker or mint into its decimals, spot price and liquidity — and warns you when several tokens share a ticker.
Quote the rungs
For each size we ask the Jupiter router for an exact-in quote: spend USDC to buy, or sell the matching token amount for USDC.
Measure
We read price impact from each quote and compute the all-in result against spot, which captures fees and transfer taxes too.
Draw the section
Buys rise above the spot line and sells fall below it. The largest size whose cost (impact or all-in, whichever is larger) stays under 1% is named the quiet floor.

What the section is good for
Check the exit door
A token can be easy to buy and hard to sell. The basement half of the drawing shows how much a sale would cost you.
See past market cap
A big market cap with a thin ladder means the price is fragile. Depth is the honest number.
Compare tokens
Run two tokens back to back to see which one absorbs a $10k order better.
Spot transfer taxes
Token-2022 transfer fees show up as a gap between impact and all-in cost — BERN is a good example.
Learn routing
Larger sizes are often split across several venues. The route column shows where the router found depth.

Depth notes
A practical guide to price impact on Solana.
Price impact is the slope of the stairs
When you trade against an automated market maker, your order changes the pool's balance and therefore its price. Price impact is how far your own trade pushes the price away from where it started. Small trades barely move it; large trades climb steep stairs. Impact depends on how much liquidity sits near the current price — not on market cap.
A worked example (formula, not live data)
In a classic constant-product pool (x × y = k) holding a quote reserve Y, spending Δ moves the price by roughly Δ ÷ Y. If the pool's total liquidity is L dollars, about half is the quote side, so impact ≈ 2Δ ÷ L. A $10,000 buy into a $1,000,000 pool therefore moves the price about 2%; the same buy into a $100,000 pool moves it roughly 20% (the approximation understates very large trades).
Concentrated and binned liquidity
Many Solana venues — Orca Whirlpools, Raydium CLMM, Meteora DLMM — let liquidity providers concentrate funds in a price range or in discrete bins. That makes the first steps very shallow while depth lasts, then suddenly steep when your trade walks out of the busy range. This is why a ladder tells you more than a single liquidity number.
Impact, slippage and fees are different things
Price impact is predictable at quote time. Slippage tolerance is the extra movement you allow between the quote and execution, because other trades land first. Fees are what the pools charge, usually a fraction of a percent per hop. A Token-2022 transfer fee is a tax built into the token itself. Quietfloor's "all-in vs spot" column bundles impact, fees and taxes together.
Why the router splits
Jupiter searches many venues and can split one order across several routes, so the effective ladder is the combined depth of all of them. That is why the routes for $100 and $100,000 often look completely different.

Questions
Are these real prices I could trade at?
They are real, live quotes from Jupiter's public router at the moment you ask. Markets move every few hundred milliseconds, so actual execution can differ — especially for volatile or thin tokens.
Why does the ladder take a few seconds?
Jupiter's free public endpoint allows only a few requests per second. Quietfloor sends the ten quotes one by one, about 1.6 seconds apart, and retries politely if it is told to slow down.
Why is buying cheaper than selling (or the reverse)?
Depth is often asymmetric: liquidity providers may have more of one side, concentrated ranges may sit above or below the current price, and some tokens tax transfers. The two halves of the drawing make that visible.
What does "no route" mean?
The router could not fill that size at all — usually because the pools are too small, or the token can't be traded on the venues Jupiter covers.
Why is a negative all-in number possible?
The spot price used for comparison is Jupiter's reference price, which can lag the best venue slightly. When a route beats it, the all-in difference is a small negative.
Can I place the trade from here?
No. Quietfloor is read-only: no wallet connection, no signing, no swaps.
Why do several tokens appear when I type a ticker?
Anyone can create a token with any ticker. Quietfloor shows the matches so you can pick the right mint — always confirm the address.

Limits & honesty
- All quotes and prices come from Jupiter's public, keyless API (
lite-api.jup.ag). It is rate-limited; if it refuses, the rung shows a retry note. - Quotes are snapshots. They do not include network or priority fees, and they don't account for other traders moving first.
- Venues Jupiter does not route through are not counted.
- The 1% "quiet floor" threshold is Quietfloor's rule of thumb, chosen only to summarise the drawing.
- Liquidity and spot price figures are Jupiter's estimates.
- Not financial advice. Quietfloor never trades and never asks for a wallet.
