ACCOUNTING

The ledger is the product.

Every order produces a receipt that itemizes to zero. Margin, fee, impact, PnL — every line accounted, every balance derivable from your own history.

Fail-closed by design — on stale prices the venue pauses orders, never improvises. “Prices stale — orders paused.”

Your order executes against the vault at oracle ± spread — no book to jump, no queue to game.
