Monarch.hl

Monarch.hl is a browser extension for Hyperliquid that overlays assets, positions and profit and loss on the native trading interface as a sidebar, and adds copy trading. It addresses the lack of portfolio view and historical analysis in the native interface: the extension reads account positions and fills, computes unrealized PnL and margin usage, mirrors a target address trade by trade with position size scaled to capital, and reads account data only within the scope the user authorizes.

It positions itself as the position and copy-trading tool layer for Hyperliquid, differing from web wallets in that data is aggregated inside the local browser rather than through a third-party server. The product ships as a browser extension with a separate documentation site describing permissions and data sources.
