Jun 1, 2025June 2025 monthly summary for fedimint/fedimint: Delivered two high-value updates enhancing payment reliability, safety, and automation readiness. Implemented an invoice payment verification endpoint in the recurring daemon with LUD-21 (light) support, updating the recurringd API and internal logic to verify invoice payment status. Fixed wallet-client behavior to skip on-chain deposits smaller than the federation fee, mitigating economic risk and preventing potential panics. These changes improve reliability of payments and on-chain interactions, reduce risk, and set the stage for smoother future releases.
