HYPERBOOK
Elysium · 99901
Hyperbook signs HyperCore's book every ~100 ms and verifies it on Elysium. On top: WHYPE/USDC and KNTQ/USDC pools that price like the exchange and charge arbitrageurs instead of LPs, USDC-margined perps settled against the real book, and a public snapshot API any contract can consume. A small protocol share of every swap and all perp fees flow into an on-chain buyback that burns the protocol token.
Uniswap v4 WHYPE/USDC and KNTQ/USDC. The hook reads the signed HyperCore mid, spread and volatility on every swap and sets the fee dynamically. Trades that pull the pool toward the exchange pay the baseline; trades that exploit a stale pool pay the deviation. LPs keep what arbitrageurs used to take; a fixed protocol share of each swap goes to the buyback and is burned.
Perpetuals that execute at HyperCore's marked book price, margined in real USDC on Elysium. Opens, closes and liquidations all carry a fresh signed snapshot, so the contract never trusts a price older than 3 seconds. Composable from any Elysium contract.
EIP-712 payloads with mid, bid/ask, 25 bps depth, imbalance, volatility and slippage. Verified by BookAttestor on-chain; free over REST and WebSocket. When Elysium ships the native precompile, PrecompileBookOracle drops in without touching integrators.
Every swap carries a signed HyperCore snapshot in hookData. The hook computes baseline = 0.03% + k·spread + k·volatility. If the trade moves the pool away from HyperCore's mid (an arbitrageur exploiting stale pricing) the fee rises to cover the deviation: fee = max(baseline, |deviation| + ½ spread + 3 bps). No fresh snapshot → 1% blind fee.
Why LP here: on a fixed-fee pool, whenever HyperCore moves, arbitrageurs buy your tokens at the old price — the "LVR" leak. Here that trade is repriced to the real deviation, so the leak becomes your fee income. Liquidity is full range so the pool is always quoting.
The vault is the counterparty to every BookPerp position. It receives open/close fees, funding on the heavier side and a share of liquidation bounties. Trader profit comes out of the vault; trader losses go into it. Share price moves with the net result.
Risk: this is a directional, undercollateralised strategy. Open interest is capped at — of vault assets and positions are liquidated at maintenance margin by a permissionless keeper, but a fast move against a crowded side can produce losses. Deposit only what you are prepared to lose.

Every run: USDC → KNTQ on the Hyperbook KNTQ/USDC pool → HBOOK on its Forge pool → 0x…dEaD. The AnchorHook sends its protocol share of every swap straight into it, and BookPerp's protocol fees are claimed into it. Triggered by the keeper, totals on-chain.
Snapshots are signed by Hyperbook's attestation service (public HyperCore feed today; L4 node feed on upgrade). Signer set and freshness are enforced by BookAttestor; the oracle interface stays identical when the native Elysium precompile goes live.
