Etherscan Gas Tracker

Gas is the fee paid to Ethereum validators for processing transactions. The Etherscan Gas Tracker at etherscan.io/gastracker shows real-time gas price recommendations in Gwei (one billionth of an ETH) for three speed tiers: Slow, Standard, and Fast. Understanding how to read and use the gas tracker is one of the most practically useful Etherscan skills — it directly affects how much you pay for every Ethereum mainnet transaction.

How to Use Etherscan Gas Tracker

Etherscan requires no account or login — just visit etherscan.io and start exploring.

01

Visit the Gas Tracker

Go to etherscan.io/gastracker or click "Gas Tracker" in the main Etherscan navigation.

02

Read the Three Tiers

Slow = cheapest, 5-10 minute confirmation (or longer). Standard = moderate, 1-3 minutes. Fast = most expensive, next 1-2 blocks.

03

Calculate Your Cost

A simple ETH transfer uses exactly 21,000 gas. Multiply the Gwei price by 21,000 and divide by 1,000,000,000 to get the cost in ETH. At 20 Gwei: 20 × 21,000 / 1B = 0.00042 ETH.

04

Choose Your Tier

Not urgent? Use Slow. Need it soon? Use Standard. Time-critical (DeFi arbitrage, NFT mint)? Use Fast or set a custom gas price.

05

Check Timing Patterns

Gas is typically cheapest on Saturdays and Sundays UTC morning. Most expensive on weekday US trading hours. The historical chart on the Gas Tracker page shows patterns.

FAQ

Questions About Etherscan Gas Tracker

What is Gwei on the Etherscan gas tracker?
+
Gwei is a denomination of ETH — one Gwei equals 0.000000001 ETH (one billionth of an ETH). Gas prices on Ethereum are quoted in Gwei. A standard ETH transfer costs 21,000 gas units; at 20 Gwei per unit, the total fee is 420,000 Gwei = 0.00042 ETH.
What gas price should I use on Ethereum?
+
Use the Etherscan Gas Tracker\'s "Standard" recommendation for most transactions. Use "Slow" if you are not in a hurry and want to minimize costs. Use "Fast" or higher only for time-sensitive transactions like participating in limited NFT mints or DeFi arbitrage.
Why is Ethereum gas so expensive sometimes?
+
Gas prices rise when demand for Ethereum block space exceeds supply. Popular NFT mints, major DeFi events, market volatility, and large protocol deployments all drive up gas as users compete to get transactions processed quickly.
What is the best time to transact on Ethereum for low gas?
+
Historically, the lowest gas prices occur on weekends (especially Saturday/Sunday) during early UTC morning hours (1:00-8:00 AM UTC). Avoid US market hours on weekdays (2:00-10:00 PM UTC) when gas tends to peak.
What does "mempool" mean on the Etherscan gas tracker?
+
The mempool (memory pool) is the waiting area where unconfirmed Ethereum transactions sit before being included in a block. A large, growing mempool indicates high network demand and rising gas prices. A small, shrinking mempool suggests low demand and potentially lower gas costs.
Reviews

What Users Say

Mainnet Cost Optimizer
★★★★★

"Checking the Etherscan gas tracker before every significant transaction has saved me significant amounts on fees. The habit of waiting for "Standard" to drop below 20 Gwei has paid back months of gas savings."

NFT Minter
★★★★☆

"Essential tool for NFT mint timing. The "Fast" tier during a hyped mint can still fail — but at least knowing the current gas baseline helps set a competitive gas price. The pending transaction counter is especially useful."

Gas Alert User
★★★★★

"Set up a gas alert via my free Etherscan account to notify me when gas drops below 15 Gwei. Got several overnight alerts that let me process large transactions at minimal cost."
