What dcSpark does
dcSpark is a remote-first blockchain infrastructure company that builds crypto products targeting interoperability and composability within the Cardano ecosystem and adjacent chains. The company's core product portfolio includes Flint Wallet (a multi-platform Cardano cryptocurrency wallet for iOS, Android, and web extension with dApp browsing and hardware wallet support), Milkomeda (an EVM-compatible sidechain for Cardano featuring Wrapped Smart Contracts technology that enables mainnet wallets to call sidechain contracts without native integration), Carp (an internally developed blockchain indexer), Paima Engine (a framework for onchain games and autonomous worlds), and Shinkai Network (an open-source AI Agent OS for private peer-to-peer agent communication with native Web3 integration).
The company's technical differentiators include being a core contributor to multiple ecosystem projects, authoring the original CIP8 Message Signing Specification for Cardano, and operating an API-first, developer-facing infrastructure model with open-source SDKs and libraries. dcSpark serves as a core contributor to projects owned by external entities, including the Shinkai Foundation.
The business model is primarily grant-driven and consultancy-oriented rather than transactional SaaS. Revenue streams include Cardano Catalyst treasury grants (where dcSpark completes approximately 5-10% of all completed proposals despite submitting only 1% of total proposals, across Funds 5-10), Urbit ecosystem grants (9 completed), and blockchain consulting services. Pricing is not publicly disclosed and the company does not appear to operate traditional commercial pricing models. Customer segments are ecosystem developers, Web3 gaming projects, and blockchain infrastructure projects rather than enterprise SaaS buyers. The company is backed by six investors (Archetype Ventures, Assembly, SOSV, Wave, Graph, and Project23) and operates with over 30 team members globally.
