Glamsterdam Hard Fork: Out of gas, still running

About this video

The video explains how the upcoming Glamsterdam hard fork changes gas accounting, allowing contracts to end up with more gas after a failed call. It shows why this can mislead existing contracts that assume gas only decreases, and offers a checklist for developers and auditors. It’s aimed at smart‑contract developers and security auditors.

What it covers

• Gas accounting will change: new storage costs can be refunded later.
• Contracts may retain more gas after a failed call, breaking existing assumptions.
• Simple examples illustrate how this can cause contract failures.
• A checklist is provided for developers and auditors to review before the upgrade.
