03 / A FEW DETAILS
Good to know.
Is this a security audit?
No. It checks block-timing assumptions around Denim. A clear result is not a guarantee of safety, an audit, or a certification.
What does the free check cover?
Public, Sourcify-verified code for a Base address, with verification and proxy details. Off-chain keepers, indexers, unverified code, and behavior outside the scanner’s rules are not covered.
Do I need to connect a wallet?
No. Just a public contract address. There are no signatures or transactions.
When does Denim activate?
The configured target is November 5, 2026 at 18:00 UTC. Activation timing may change; confirm it in the official Base schedule.
