EVM Prime Broker Sandbox
A first move on the still-open on-chain prime broker market.
Past the lending layer Aave, Morpho, and Pendle own, no one yet binds cross-margin lending, perp, and spot under one risk engine. This sandbox maps that gap — portfolio-level health checks drive liquidation across the whole book, runnable before you build into it.
Not transaction simulation against a live, deployed protocol — that is the operations layer. This is the engine itself: open, runnable, and forkable, before you build one.

What you can do here
Open OpenHL — CLOB, funding, liquidation, insurance fund, ADL — and read every primitive in source.
Run crash, ADL, oracle, and margin scenarios — each emits a verifiable pass/fail report.
Turn a design dial (like maintenance margin) and watch the outcome shift — proof it bends to your needs.
Adopt the open source, or take it further with a custom build or hosted access.
