    ink-kit

    ink-kit

    Onchain-focused SDK with ready-to-use templates and themes

    ...It provides contract templates, deployment scripts, and client SDKs so you can iterate on on-chain logic and a frontend without stitching together disparate tools. The kit standardizes project layout and environment configuration, making local development, testing, and staging deploys predictable. Utilities for wallet connection, signing, and basic indexing help you focus on business logic rather than bootstrapping. Example apps and guides demonstrate common patterns—minting, access control, payments, and simple off-chain integrations—so teams can adapt and extend quickly. The overarching goal is to reduce time-to-first-transaction and give projects a maintainable base that scales as features grow.
