PROFILE

Sabine Schaller

During January 2025, Sabine developed a critical wallet key management feature for the interledger/rafiki repository, focusing on enforcing a single unique active key per wallet address. She implemented a database migration using SQL to guarantee key uniqueness and updated the backend service layer in TypeScript and JavaScript to handle duplicate key creation attempts gracefully. Her approach included robust handling of revoked keys, ensuring that previously revoked keys for the same wallet address and key identifier were managed correctly during new key creation. This work enhanced the security and data integrity of wallet key management, addressing edge cases and reducing lifecycle ambiguity.
