Gas Fee Predictor

Best Time to Send ETH Right Now

Live decision

How the decision is made

The card above blends three live signals to give you a one-line answer:

  • Current Gwei: pulled every 30 seconds from public Ethereum gas trackers.
  • Next forecasted lower window: our pattern-based predictor scans the next 12 hours and finds the cheapest 1-hour bucket it can identify with confidence.
  • Decision threshold: if the predicted window saves you more than 30% and arrives within a reasonable wait, we suggest waiting. Otherwise the answer is "send now."

Hit rate over recent weeks: the predicted window lands in the cheapest quarter of the next-12h period about 55% of the time — meaningfully better than random timing, but not magic. Treat it as a tiebreaker, not a gospel signal.

When is ETH cheapest to send?

  • Saturday late night to Sunday morning UTC — usually the week's cheapest stretch
  • Weeknights, 02:00–06:00 UTC — US asleep, Asia not yet ramped
  • Right after a congestion spike resolves — base fee decays quickly
  • Sunday evening UTC — pre-Monday lull
  • Outside major NFT mint or token launch windows — check the calendar before timing

How to make the wait easier

  • Set a gas alert. Pick a target Gwei — we email you when live gas drops below it.
  • Use Standard tier. Wallets default to Fast. Standard saves 20–40% and still confirms in a few minutes.
  • Check the forecast first. The 24-hour gas fee forecast shows the full trend, not just one bucket.
  • If you can settle elsewhere, use an L2. Arbitrum, Optimism, Base, Polygon all run at a fraction of mainnet cost regardless of timing.

Frequently asked questions

Should I send ETH right now or wait?

The decision card above gives you a live answer. We compare the current gas price against the next forecasted lower-fee window (up to 12 hours out). If the savings are more than 30% and you can wait, we recommend waiting. Otherwise, send now.

What time of day is gas cheapest for sending ETH?

Late night UTC (02:00–06:00) on weekdays, and most of Saturday and Sunday. US daytime hours (14:00–22:00 UTC) tend to be 3–5x more expensive due to peak DeFi and NFT activity.

How much can I save by waiting for a cheaper window?

On a typical week, the difference between peak and off-peak gas is 50–80%. A $25 ETH transfer at noon UTC might cost $5 the same night. For a $1,000 USDT transfer or a Uniswap swap, that gap compounds.

How accurate is the "best time" prediction?

It's a directional signal, not a guarantee. Our pattern-based predictor lands in the cheapest 25% of the next-12h window about 55% of the time — 2x better than random timing, but not infallible. Sudden NFT mints or news events can shift the picture in minutes.

Can I get notified when ETH gas drops?

Yes. Set a gas alert at your target Gwei threshold. We email you the moment live gas crosses below it, so you do not have to keep refreshing this page.

Does the decision change for ERC-20 tokens or NFTs?

Same timing logic applies — gas-cheap windows are gas-cheap regardless of transaction type. The dollar savings just scale with the gas units used (a swap saves ~7x more than a plain ETH transfer for the same Gwei drop).

Should I use a Layer 2 instead of timing mainnet?

If your destination accepts L2 tokens, yes — Layer 2 transfers cost cents regardless of mainnet conditions. Use this page to time mainnet only when you have to settle on L1 (e.g., depositing to a CEX that does not support L2 withdrawals).
