Pump a pool.The priceshrugs.

JIKA is the price of every token on Solana, read on chain from every pool it trades in. Deep pools count more, money poured in at the last moment counts for nothing, and every price carries a band that says how sure it is.

7: DEX programs it reads: Orca, Raydium three ways, Meteora, pump.fun and PumpSwap.
6,400: compute units for a program to read a price through one CPI.
0: admin keys, publishers or applications. A pool exists, so a price can.

JIKA: the price of the moment

A real thin token, three real pools

Pools pushed: not yet
JIKA price: $0.001445
Band: ± 1.20%
Lender, 3% limit: reads
Time: now
It cost you: 0 SOL

Three pools, one price.

A real thin token: three pools, 44.93 SOL of depth within 2%. Pick how far to push it, then how.

Push the pools up by: nothing yet

01 Read every pool

Up to eight pools per token, from Orca, Raydium, Meteora, PumpSwap and the pump.fun curve. The program reads each pool's price and depth from the pool's own account. Nobody sends it a number.

02 Weigh by depth

Depth is the SOL it takes to move a pool 2%. A pool 23 SOL deep counts for more than one 10 SOL deep, in exact proportion.

200 SOL added to a 10.47 SOL pool and kept. Dashed: in the pool. Blue: what it may count.

1 min: 26 SOL
10 min: 135 SOL
25 min: 193 SOL

03 Count only depth that stayed

A pool's vote is capped at the depth it held across earlier reads, averaged over about ten minutes. Liquidity added for one transaction buys no say.

Half the depth is passed inside the deepest pool: its price is the price.

04 Take the middle

Line the pools up by price and stop where half the depth has been passed. To move that point you have to move pools holding more than half the depth.

At rest: ± 1.20%

During a 5% spike: ± 8.98%

During a 20% spike: ± 22.36%

A lender asking for 3% or better reads the first and refuses the other two.

05 Draw the band

Pools that disagree, a middle that jumps away from the steady price, or a token too thin to take 1 SOL: each one widens the band, and a reader can refuse it.

A 20% spike every 10 seconds. Blue: nobody refreshing. Light: a keeper.

Nobody refreshing: +20.27% in 260 s
A keeper every 10 s: 0.00%

06 Move slowly, stamp the slot

The price programs read follows only the least extreme of the last three 10-second windows, at most 0.77% per window. One honest reading in any window pins it. Each price carries its slot.

Every step runs inside one instruction, each time the price is read.

The doubts, answered

Prices from pools get pumped. Mango lost over $100M that way in 2022.
Mango read one thin market's price as it stood. On a real thin token, a 20% spike across every pool, sold back in the same transaction, cost 11.49 SOL and moved the JIKA price 0.00%. The band jumped to ±22.36%, so a careful lender refused it.
And a patient attacker?
With nobody refreshing the price, spiking every 10 seconds walked it up 20.27% in 260 seconds for 241.51 SOL. With a keeper refreshing once every 10 seconds, 60 spikes over 624 seconds moved it 0.00%. Run a keeper: about 0.043 SOL a day.
What if nobody refreshes it for an hour?
Every price carries the slot it was computed in. Your program passes the oldest slot it accepts, and the read fails instead of handing over an old number. Anyone can refresh a price, any time.
What about a token with one tiny pool?
The band always includes how far a 1 SOL trade would move the token. A live pump.fun curve with 0.68 SOL of confirmed depth read at ±6.05%. For the thinnest tokens the band says: not known yet. That is the honest answer.
Why not just use Pyth?
Pyth prices the assets its publishers choose. JIKA prices any token with a pool, from the moment a pool exists, with nobody to apply to. Majors can keep reading Pyth; the long tail reads JIKA.
Who can change the rules?
The program has no admin key. Anyone can create a token's price or add a pool to it, and a new pool starts with zero say until its depth has stayed. A new kind of DEX needs a new program version.
