Crypto Gas Fee Tracker
Compare live gas fees across Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, and Avalanche before you swap, bridge, mint, or move funds.
Fee speed curve
Slow, standard, and fast fee estimates for the selected network| Network | Slow | Standard | Fast | Transfer | Swap | Status |
|---|
For EVM networks, estimates use gas units multiplied by gwei price and native coin USD price. This page is educational and should be compared with your wallet before confirming a transaction.
Use gas data before you move money.
Gas fees are one of the easiest costs to ignore and one of the fastest ways to turn a small transfer, swap, bridge, or mint into a bad trade. This tracker helps you compare network cost before you confirm a wallet transaction.
Estimate the real transaction cost
Select a network, choose the transaction type, and compare slow, standard, and fast fee estimates in both native coin and USD.
Compare Ethereum and L2 networks
Ethereum mainnet can be expensive during congestion, while Base, Arbitrum, Optimism, Polygon, BNB Chain, and Avalanche often provide cheaper execution.
Plan swaps, bridges, and mints
Model common actions before opening your wallet so you can decide whether to wait, use a cheaper route, or batch multiple actions together.
What are crypto gas fees?
Gas fees are the network costs paid to process a blockchain transaction. On Ethereum and most EVM-compatible chains, the fee is based on the amount of computational work a transaction uses, the current gas price, and the native token price.
A simple token transfer usually uses fewer gas units than a DEX swap, bridge transaction, NFT mint, or complex DeFi interaction. That is why two transactions on the same network can have very different costs even when the token amount is the same.
- Gas units describe how much work the transaction requires.
- Gwei price reflects current network demand and priority fee conditions.
- Native coin price converts the fee into USD so you can compare networks clearly.
How to reduce gas fees without taking unnecessary risk.
Lower fees are useful, but the cheapest option is not always the safest. Use these checks before moving funds across networks or signing a smart-contract transaction.
Wait when the network is crowded
If a transaction is not urgent, check again later. Gas often changes across the day as network activity, liquidations, NFT mints, and market volatility rise or fall.
Use L2s for smaller transactions
For routine swaps and transfers, Layer 2 networks can reduce costs. Still verify bridge security, withdrawal times, and whether your destination supports that network.
Review the wallet quote
This tracker is an estimate. Your wallet has the final transaction details, including exact gas units, max fee, priority fee, contract route, and any slippage settings.
Gas fee tracker FAQ.
Quick answers for common questions about gwei, Ethereum gas, L2 fees, swaps, bridges, and wallet quotes.
Does this gas fee tracker show live data?
Yes. The tool attempts to refresh gas data from public RPC endpoints and native coin prices from public market APIs. If a network endpoint is unavailable, the page shows a fallback estimate and labels it clearly.
Why is my wallet showing a different gas fee?
Wallet quotes can differ because the wallet knows the exact contract call, route, priority fee, slippage settings, and gas limit. This page is designed for planning and comparison before you confirm the final wallet transaction.
What is gwei?
Gwei is a small unit of the native gas token, commonly used to quote gas prices on Ethereum and EVM networks. A higher gwei price means you are paying more per unit of gas work.
Why are swaps more expensive than transfers?
A basic token transfer is usually simple. A swap may interact with liquidity pools, routers, approvals, and multiple contract calls, so it normally uses more gas units.
Are Layer 2 networks always cheaper than Ethereum mainnet?
They are often cheaper for everyday transactions, but not always the best choice. You still need to consider bridge costs, withdrawal delays, supported assets, exchange deposit support, and smart-contract risk.
What is the best time to send a crypto transaction?
The best time is when network demand is lower and the transaction is not urgent. Use the slow, standard, and fast estimates to decide whether waiting is worth it for the amount you are moving.
Can gas fees make a small trade unprofitable?
Yes. If the fee is large compared with the trade size, expected profit, staking reward, or bridge amount, the transaction may not be worth doing. Compare the gas estimate with your expected outcome first.
Is this financial advice?
No. The Crypto Town provides educational tools and estimates only. Always verify final fees in your wallet and make your own decision before signing a transaction.
Compare fees before your next transaction.
Use the live tracker above, then check your wallet quote before you approve a transfer, swap, bridge, mint, or DeFi interaction.
