Overview

The Euclid network upgrade is coming, introducing major improvements including :

• Lower fees & higher throughput
• Migration to OpenVM Prover & MPT state commitment
• Optimized rollup process
• Support for EIP-7702 & RIP-7212
• Stage-1 security readiness

Timeline

As the upgrade is huge, we separate the upgrade into two phases. Following is the upgrade timeline:

• Sepolia testnet
  • Phase 1: Tue Mar 11 2025 08:00:00 GMT+0000 at timestamp 1741680000
  • Phase 2: Thu Mar 13 2025 08:00:00 GMT+0000 at timestamp 1741852800
• Mainnet
  • Phase 1: Tentatively 2025 April 15th (Tue)
  • Phase 2: Tentatively 2025 April 22nd (Tue)

Impact on Users

Users should expect a slightly degraded experience during the upgrade. This will last between a few hours and one day, and will entail the following:

• During phase-1, batch finalization is expected to be delayed by several hours. Users should expect increased withdrawal times.
• During phase-2, Scroll will migrate to a new message queue contract. As a result, we expect slightly increased delays when depositing funds to Scroll.

Impact on Node Operators

For Euclid phase-1 (MPT Migration), node operators should migrate to the new MPT version of l2geth. This requires a full resync (from network or from snapshot). We will provide a node release and snapshots later. Please refer to Node Runner State Migration Guideline for node runner state migration guide.

Zktrie nodes will continue to operate, but they will stop verifying state roots on the received block headers. We encourage node operators to migrate to mpt nodes shortly before Euclid.
