Arsia is the next major Mantle network upgrade, following the Limb fork. It unifies multiple OP Stack forks (Canyon, Delta, Ecotone, Fjord, Granite, Holocene, Isthmus, and Jovian) into a single coordinated activation event.
Arsia is scheduled to activate on Mantle Sepolia at L2 block timestamp 1774422000 (Wednesday, March 25, 2026, 07:00:00 UTC).
Warning
All Mantle Sepolia node operators must upgrade to this release before the activation time.
What's Changed
- all: Activate 8 OP Stack forks (Canyon, Delta, Ecotone, Fjord, Granite, Holocene, Isthmus, Jovian) simultaneously at the Arsia timestamp via

- op-batcher: blob data format changed; span batch and brotli compression support
