EVM Prime Broker Sandbox
A shared-risk sandbox for desks that want one engine across lending, perp, and spot.
A runnable EVM prime broker sandbox: cross-margin lending, perp, and spot under one shared risk engine, with portfolio-level health checks driving liquidation logic across the whole book.
Reactor is not protocol operations tooling for an existing venue. It is a pre-implementation sandbox for DeFi strategy, market structure, and risk design.
Sandbox dossier · Runnable evidence · Scenario surface
A runnable market-structure lab with fixed scenarios, explicit reports, and a source trail. This is not ops software for a deployed protocol. It is a sandbox dossier for a specific engine category before implementation.
On-chain prime broker is structurally uncrowded on EVM. Aave, Morpho, and Pendle are strong as lending primitives, but no major player composes cross-margin, lending, perp, and spot under one risk engine. The EVM Prime Broker Sandbox is the runnable reference for teams trying to map that gap before they build into it.
In Fabrknt, EVM Prime is a pressure-bearing sandbox where market design, trust assumptions, and operational discipline all become legible under stress.
