Proof
Two shadow vaults, $50,000 each, run every hour on the vault contract's own trading rules. Each order is filled against Hyperliquid's real order book at that moment, with Hyperliquid's real fees and holding costs. Nothing is sent and no money moves. When a real vault is deployed, each order here gets a link to it on chain.
Value, Hour By Hour Paper, live
What $100 has become in each shadow vault, next to just holding the same three coins.
Red Days
A receipt for every UTC day a vault lost money: how much the coins moved, how much the bets paid back, and what it cost.
Every Order
Newest first. "Vs mid" is how far the average fill was from the middle of the book: the cost of crossing the spread and eating the book.
What This Proves

Fills, slippage and fees on Hyperliquid's real mainnet books, every hour.
Real hourly funding paid to (or by) the bets.
How far leverage drifts between hourly checks.

Where our orders would sit in the queue, and other traders reacting to them.
Deposits and withdrawals by other people. These shadow vaults have one fixed deposit.
Bridged coins (Unit Bitcoin, Unit Solana) are valued at the main oracle price, as the contract does.
