Professional quotes,
on-chain,
every block.
Quotient is a PropAMM venue for Elysium. Market makers post prices from their own inventory, refreshed every block, and traders fill against them through standard Uniswap v4 swap paths.
We are the venue, not the market maker. The quotes are theirs; the hook enforces them.

Why on-chain spreads are wide
A PropAMM lets the market maker set the price, not a formula.
The curve is always late
A passive AMM prices with a formula. When the market moves on Hyperliquid, the curve does not, and arbitrageurs trade against it until it catches up. LPs pay for that, so pools charge wide fees and traders pay them.
Off-chain quotes do not compose
Professional makers quote tight spreads, but on-chain they mostly do it through RFQ: signed off-chain, gated by API keys, often with last look. Routers cannot read those quotes like a pool, and contracts cannot call them.
Elysium removes the excuse
Real blocks every ~120 ms and a quote update that costs about $0.0002. For the first time on an EVM chain next to Hyperliquid, a maker can refresh an on-chain price every block and still make money.
How it works
Read the docs →One storage slot per pool.
Mid, both spreads, a per-block size cap, size impact, age decay, time-to-live, sequence and flags pack into 32 bytes. Batch every pool in one transaction: 29.4k gas for the first, 5.8k for each extra.

Standard Uniswap v4 paths.
Pools are ordinary v4 pools with a custom-curve hook. The Universal Router, the official V4Quoter and any v4-aware aggregator route in unchanged. The view quote matches the swap to the wei.
Stale quotes price themselves out.
The contract stamps each quote with its inclusion L2 block. Quotes expire after a maker-set number of blocks, widen with every block of age, cap fills per block, and can demand same-block freshness.
