Why check ETH gas before every transaction?
Save $10β$50 per swap
Ethereum gas swings from 1 Gwei off-peak to 100+ Gwei during congestion. A single Uniswap swap can vary by $20β$50 depending on timing. Checking first lets you pick a cheap moment.
Avoid stuck transactions
Set gas too low while the network is busy and your transaction stays pending β forcing a costly speed-up. The tracker shows the minimum needed to land in the next block.
Know when to bridge to an L2
When ETH gas spikes, bridging to Base or using BNB Chain is 100β1000Γ cheaper. Compare all three networks quickly to decide where to transact.
When is Ethereum gas cheapest?
ETH gas depends on pending demand in the mempool. The quietest windows tend to be:
- 1Saturday β Sunday, 8 PM to 6 AM UTC β global low-traffic period
- 2Weekday early mornings, 2β8 AM UTC β before European and US markets open
- 3Avoid peak hours: 1 PM β 11 PM UTC β US and EU markets fully active
- 4Avoid major events: hot NFT mints, token launches, airdrop claims β gas can spike 10β50Γ
How to read the ETH Gas Tracker
- 1
3 speed tiers: Standard / Fast / Rapid
Standard (~30s): the default wallet tier, fine for most transactions. Fast (~15s): higher priority fee. Rapid (~10s): highest priority, for volatile conditions.
- 2
Gwei and how fees are calculated
1 Gwei = 0.000000001 ETH. Cost = Gas price (Gwei) Γ Gas limit Γ· 1,000,000,000. A Uniswap swap uses ~357,000 gas Γ 2 Gwei = 0.000714 ETH. The tracker pre-computes this in USD.

Base fee vs Priority fee (EIP-1559)
Total fee = Base fee (burned, adjusts with congestion) + Priority fee (tip to validators). When the network is busy the base fee rises fast β that's when to pick Fast or Rapid.

Frequently asked questions about ETH gas
What is the ETH gas fee today?+
ETH gas changes every block (~12s). Off-peak it's often 1β5 Gwei (ETH transfer $0.5β$5, swap $2β$15); when busy it can hit 20β100+ Gwei with swaps costing $30β$100+. The tracker above shows the live Gwei right now and converts it to USD per transaction type.
How are Ethereum gas fees calculated?+
Cost (ETH) = Gas price (Gwei) Γ Gas limit Γ· 1,000,000,000. Example: an ETH transfer uses 21,000 gas Γ 2 Gwei = 0.000042 ETH β $0.09 (at $2,000/ETH). Complex swaps use 150,000β400,000 gas. The estimate table above pre-calculates transfer, swap, NFT and bridge.
What is a normal ETH gas price?+
Under normal conditions: 1β5 Gwei. During hot NFT mints or major launches: 20β100+ Gwei. Watch the tracker for the current rate before transacting.
What is the difference between Base fee and Priority fee?+
Base fee is the mandatory minimum, burned under EIP-1559 β it doesn't go to validators. Priority fee is an optional tip for faster inclusion, paid to validators. Your total = Base fee + Priority fee.
How can I save on gas when swapping on Ethereum?+
1) Transact on weekends, 8 PMβ6 AM UTC. 2) Set max fee just above base fee β don't overpay. 3) Use an aggregator like 1inch for gas-efficient routes. 4) Bridge to Base if you don't strictly need mainnet.
