Worked on the hyperledger-labs/splice-wallet-kernel repository to deliver a CIP-103 compliant Wallet Event Delivery system, focusing on reliable event propagation and dApp integration. Developed the DappSyncProvider to enable JSON-RPC 2.0 notifications with targeted delivery, addressing event delivery gaps and ensuring robust per-request routing. Enhanced the WindowTransport path by installing an always-on listener and per-request IDs to prevent silent event drops. Bridged transport notifications to AbstractProvider.emit for seamless end-to-end lifecycle delivery. Expanded the TypeScript-based test suite to validate envelope semantics, targeted delivery, and cross-wallet isolation, laying groundwork for improved multi-wallet support and developer experience.
