Proposal: PartyLayer — Open-Source Wallet Abstraction Layer for Canton
Development Fund Proposal Submission
Proposal file:
./proposals/PartyLayer-Wallet-SDK.md
Summary
PartyLayer is a production-ready, CIP-0103–native wallet abstraction and application-layer interoperability infrastructure for the Canton ecosystem.
The SDK is already live and actively used, with 5 wallet integrations completed and CIP-0103 compatibility implemented. It operates strictly at the application integration boundary, providing standardized wallet connectivity, a CIP-0047–aligned activity interface (without modifying reward logic), and production-grade infrastructure including observability, structured logging, and standardized error semantics aligned with CIP-0103.
PartyLayer is additive infrastructure. It does not modify protocol rules, validator logic, wallet authority, or reward distribution mechanisms.
