ETH Gas Spikes

What it is

When ETH gas crosses 3 gwei or jumps 4× over its recent baseline, you get pinged.

Why it matters

Sustained high gas means blocks are full and someone is paying to be inside them — a large mint, an MEV-heavy window, or a rush of on-chain activity. It is also the condition under which a pending transaction is most exposed to being front-run, because everything in the mempool is bidding for the same block space.

How to read the alert

The alert reports the current gas price and, when the jump was measured against gas's own recent level, what that normal level was. A spike has to hold for 10 minutes before it is reported, which is what distinguishes a sustained condition from a single busy block: transactions submitted during it settle at that price, and the mempool is competing rather than clearing.

Sample alert

Each alert includes

• The current gas price in gwei, and the threshold it crossed
• How long the level has been sustained, in minutes
