# September 6, 2026 — Atomic Requote v2 & Delegate Cancel

> Atomic requote v2 on Solana L1, delegate cancel without withdrawal authority, and Lite Dock 1-click execution presets.

# September 6, 2026 — Atomic Requote v2 & Delegate Cancel

Delivered core smart contract safety upgrades on Solana devnet, dedicated order delegate permissions, and enhanced execution speed in the Lite Dock.

## Smart Contracts & Core Execution

* **Atomic Requote v2**: Upgraded on-chain slab matching instructions to support single-transaction atomic order replacement (cancel + submit). Prevents sandwich attacks and eliminates execution gaps where both orders could temporarily fill.
* **Scoped Delegate Cancel**: Added fine-grained delegate keys enabling execution bots to cancel open slab orders without custody or withdrawal privileges over the trader's collateral.

## Frontend & UX Polish

* **Lite Dock 1-Click Toggle**: Smooth bottom taskbar expansion for rapid order entry on smaller screens.
* **Execution Presets**: Pre-configured leverage and size hotkeys for rapid position sizing.
* **Orderbook Depth Ergonomics**: High-visibility cumulative depth visualization with real-time spread indicators.
