🔇 Additional comments (2)

foundry.toml (1)

8-8: EVM version bump to cancun looks good; verify toolchain support

The config change is straightforward and consistent with the rest of the file. Please just confirm your Foundry/anvil versions and any CI nodes recognize cancun so you don't silently fall back or get config warnings.

.gas-snapshot (1)

1-2: Gas snapshot updates consistent with EVM bump

The reduced gas figures look like the expected fallout from switching to cancun. No issues from a correctness perspective; just ensure snapshots are regenerated whenever tests or compiler/EVM config change again so these stay in sync.
