**Scalus** is an established, open-source Cardano development platform, built by **Lantr Engineering** over three years of continuous delivery. It is the integrated, JVM-native toolset for complex protocols and mission-critical applications, such as **Gummiworm L2, Bifrost bridge, SugarRush DEX, Vela stablecoin, DID / DIDComm decentralised identity**, that build on it. Its components are already reused inside Cardano's most widely used developer tooling: **MeshJS, Evolution SDK, Lucid Evolution, Cardano Client Lib, and YaciDevKit**. Many teams depend on Scalus without ever integrating it directly. This proposal funds a focused, 9-month continuation across three lines of work: - **protect** the existing infrastructure and prepare it for the upcoming **Dijkstra hard fork (maintenance and readiness)** - **deepen** its reuse across the **JVM and JavaScript ecosystems (interoperability)** - **expand** Scalus beyond protocol development toward **operating applications (first scoped application runtime)**. It is a deliberately reduced resubmission. DReps recognised the previous Scalus proposal's vision, technical quality, and delivery record, but found its scope and budget too large. This version answers that directly: the ask is cut to **₳2,464,844** over 9 months, at a conservative **\$0.16/ADA** reference rate and **no contingency**. Delivery is milestone-based, administered through audited SundaeSwap treasury contracts with an independent oversight board and third-party assurance. The goal is bounded and concrete: protect prior public investment, keep Scalus and everything built on it working through the next protocol cycle, make it more reusable across the ecosystem, and extend it from building applications to running them. It's a proportionate continuation of proven work. **At a glance** - **Ask:** ₳2,464,844 (~\$394,375 at \$0.16/ADA) · 9 months · no contingency - **Scope:** maintenance · Dijkstra hard fork readiness · interoperability (JVM + JS/TS) · a scoped application runtime - **Excludes:** standalone L1 node · full L2 integration · broad formal verification - **Vs. previous proposal:** reduced from ₳8.5M / 12 months; L1 node and third-party dependencies removed - **Team:** Lantr Engineering, three years building Scalus, every prior milestone delivered on time - **Governance:** SundaeSwap escrow · independent oversight board · third-party assurance
