Walkthrough

The pull request updates the ScrollSepolia chain configuration to activate the GalileoV2 fork at timestamp 1764831600 and increments the patch version from 17 to 18 in the version constants.

Changes

Cohort / File(s)	Summary
Configuration Update params/config.go	Sets GalileoV2Time to newUint64(1764831600) in ScrollSepoliaChainConfig, replacing nil with a concrete fork activation timestamp
Version Bump params/version.go	Increments VersionPatch constant from 17 to 18

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes

These are straightforward value updates to configuration and versioning constants with no logic modifications or complex interactions.

🐰 A timestamp thumps, a version hops,
ScrollSepolia's Galileo never stops,
From nil to time, the fork takes flight,
Patch eighteen shines forever bright! ✨

params/config.go (1)

331-337: GalileoV2 fork time wiring for Scroll Sepolia looks consistent

GalileoV2Time is now set to newUint64(1764831600), which is strictly after GalileoTime (1764054000) and all earlier fork times (Euclid*, Feynman) on Scroll Sepolia. This preserves the expected chronological ordering and only affects the ScrollSepolia chain config, leaving mainnet and other networks unchanged.

params/version.go (1)

24-29: Patch version bump aligns with the new fork scheduling change

Incrementing VersionPatch from 17 to 18 is appropriate for introducing the GalileoV2 scheduling on Scroll Sepolia, and all version helper functions continue to derive their strings from these constants without further changes.
