PROFILE

Sabine Schaller

Over a two-month period, contributed to the interledger/rafiki repository by developing a wallet key management feature that enforces a single unique active key per wallet address, addressing security and data integrity concerns. This involved implementing a database migration in SQL to ensure key uniqueness and updating the service layer in TypeScript to handle duplicate key creation attempts and manage revoked keys effectively. Additionally, improved documentation accuracy in the interledger.org-developers repository by removing outdated references to deprecated STREAM receipts from blog content, utilizing Markdown and technical writing skills to align published guidance with current standards and minimize confusion for developers.

January 2025 (2025-01) monthly summary for interledger/rafiki. Delivered a critical security and data-integrity feature: Wallet Key Management enforces one unique active key per wallet address, with proper handling of revoked keys and transitions. Implemented a database migration to enforce key uniqueness and updated the service layer to gracefully handle duplicate key creation attempts. Ensured previously revoked keys for the same wallet address and kid are correctly managed when creating new keys. This work reduces key lifecycle ambiguity, strengthens security posture, and improves data integrity across wallet key management.
