Dubhe

Dubhe is a development engine for fully on-chain applications written in Move, combining an entity-component-system with schema-based storage: developers define components and systems, state lands on-chain in schema form, and clients read it through type-safe SDKs, removing hand-written serialisation and indexing.

The toolchain covers Sui, Aptos, Movement, Rooch and Initia, each with its own CLI, client and indexer; the indexer turns chain events into a queryable source that a GraphQL layer exposes to front ends. The engine supports logic upgrades and data migration, so a live application can swap contract logic without resetting state, and a sandbox network is used for local integration to avoid trial and error on mainnet. The code is maintained in the open, versions follow semantic numbering, and scaffolding tools generate the project skeleton.
