The Filecoin Warm Storage Service (FWSS) v1.3.1 and ServiceProviderRegistry v1.2.0 contract upgrades are scheduled for execution and validation on Filecoin Mainnet on August 12, 2026. The maintenance window starts at 14:15 UTC, shortly before the announced execution epoch 6,274,616 (approximately 14:28 UTC), and remains open through 23:59 UTC for post-upgrade validation. The existing FWSS and ServiceProviderRegistry proxy addresses will remain unchanged; the matching StateView will be switched separately only after the implementation upgrades pass validation.
