Summary

Following the approval of the Canton dApp API Standard (CIP-0103), a preview version of the dApp SDK was released and is successfully being used by the Wallet Gateway. This proposal outlines a grant for Digital Asset to continue the core development required to deliver an open source company agnostic, production-ready dApp SDK and connectivity ecosystem. While foundational architecture is in place, significant core software engineering remains to build the production SDKs, develop turn-key UI components, abstract away differences between dApp API and direct Ledger API connections for Wallet SDK compatibility, and finalize security audits. We will deliver universal wallet discovery components, integrate Wallet Connect as a core capability, execute rigorous internal and external security audits, and build an automated compliance test suite. Beyond core engineering, this grant funds dedicated, hands-on integration support to drive widespread ecosystem adoption, explicitly targeting full CIP-103 compliance across the network's top-tier dApps and major wallet platforms. This ensures that the foundational work of CIP-103 transitions into a secure, mass-adopted reality.
