v1.5.3 Sepolia Arsia

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 AlignOpWithMantle().
• op-node: Derivation pipeline now aligned with upstream OP Stack rules — strict batch ordering, no buffering or reordering, and deposits-only fallback on invalid payloads
• op-batcher: blob data format changed; span batch and brotli compression support
• contracts: New OperatorFeeVault predeploy at 0x420000000000000000000000000000000000001b
• contracts: Updated GasPriceOracle with Arsia fee model
• contracts: Updated L1Block with operator fee fields
• contracts: L1 SystemConfig upgraded with Arsia config: setGasConfigArsia() (replacing deprecated setGasConfig()), setEIP1559Params(), setOperatorFeeScalars(), setMinBaseFee(), and setDAFootprintGasScalar()

1.4.2 Mainnet Limb

Mainnet Limb Release

This release is primarily aimed at enabling the Mantle Mainnet Network to support all features of the Ethereum Osaka upgrade.
The Limb fork is scheduled to occur at 2026-01-14 07:00:00 UTC.

🚧 Note: It is a required upgrade for all operators of Mantle Mainnet Network. 🚧

Change Log

op-node: #235 #236

• Compatible with Osaka op-geth
• Use the new consensus-layer rpc eth/v1/beacon/blobs/ to query blob data. And update the blob verification logic to use KZG commitments to verify blob transaction data.

op-batcher: #235

• Added a flag to support cell proofs blob transaction submissions after Fusaka Upgrade.
• Blob base fee retrieval was changed from computing it using block header parameters to querying it directly through the L1 RPC.
• In the transaction retry mechanism, the fee increase percentage was raised to help rollup transactions confirm more quickly during network congestion.
