Oct 1, 2025October 2025 monthly summary for hyperledger-labs/splice: What was delivered: - Validator onboarding: party hint association. Implemented end-to-end support for associating a 'party hint' with validator onboarding secrets, enabling accurate party identification during onboarding and secret validation. This required changes across the API layer, storage model, and frontend components to accommodate the new mapping. Commits tied to this feature include bf9b01f8d861a1440e13e0a98df5415843f6541a (Tie validator onboarding secrets to a party hint) and 5c44ac71ae8454579b78b9c8586a9a9f598d4332 (Add release notes for validator onboarding with party hint). Key bugs fixed: - Clipboard handling for onboarding secrets in Chrome: Fixed copying onboarding secrets by switching to writeText for plaintext copy, improving reliability and usability in the Chrome browser. Commit 1cdf1ae5516b5d379a4a3c9502ceab195e38c7a0. - Security vulnerability fix: HappyDOM upgrade: Upgraded the HappyDOM library to address a vulnerability, with minor frontend refactors and test setup adjustments to accommodate the updated library. Commit ebd1cb713e8cdbdd1d911677bd685ddbaf45b73b. Impact and accomplishments: - Strengthened onboarding reliability and security: The party hint association reduces onboarding ambiguity and improves identity verification during validator onboarding, contributing to safer and more auditable operations. - Reduced surface area for onboarding errors in the browser: Chrome copy reliability improved for onboarding secrets, reducing support incidents related to miscopied data. - Improved security posture and maintenance readiness: The HappyDOM upgrade addressed a known vulnerability, with related testing adjustments to prevent regressions. Technologies and skills demonstrated: - End-to-end feature delivery across API, storage, and frontend layers, including API data modeling, storage considerations for party hints, and UI integration. - Frontend UX and browser API work (Clipboard API, writeText) to improve usability. - Dependency management and security hardening (library upgrade, tests). - Documentation and release engineering (creating release notes for the feature).
