Accepted Answer

EVMgastracker.xyz is the all-in-one hub for EVM blockchains to optimize your transactions and cut your gas fees. In one place you get the official explorers of the main EVM chains, one-click RPC switching via Chainlist, and everything you need to make the right decisions. With EVMgastracker.xyz, you can:

🚦 See at a glance which chains are calm or congested.
🔍 Instantly understand why fees are rising, thanks to “Why?”.
🔄 Switch RPC in seconds via Chainlist.
🔔 Get notified when a network calms down, so you can transact at the best moment.
📅 Use “Best time” to find the cheapest day and hour of the week to pay the lowest fees.

Whether you're an investor, trader, airdrop farmer or DeFi user, EVMgastracker.xyz helps you save time and money on all your EVM transactions.

Question 2

How do the low-gas alerts work?

Accepted Answer

Tap the bell (🔔) on any chain to follow it — you can select as many chains as you like. You'll get a push notification the moment a followed chain turns calm (its gas drops well below its usual 7-day level), so you can send your transactions when they're cheapest. It even works with the site closed once you add EVMgastracker.xyz to your home screen. No account, no email — nothing personal is stored.

Question 3

What is gwei?

Accepted Answer

Gwei is one billionth (10⁻⁹) of a chain's native gas token. On Ethereum, 1 gwei = 0.000000001 ETH; on other EVM chains it refers to their own token (BNB, MON, POL…). That's why this dashboard compares costs in USD, not in gwei.

Question 4

Why are gas fees high sometimes?

Accepted Answer

Fees rise when demand for block space exceeds supply: NFT mints, airdrop claims, memecoin trading or network congestion. The “Why?” button on each card shows which contracts are burning the most gas right now.

Question 5

What is an RPC, and why switch when a chain is congested?

Accepted Answer

An RPC endpoint is the server your wallet uses to talk to a blockchain — send transactions, read balances, estimate gas. When a chain is congested, public RPCs often get overloaded too: transactions hang, fail or get bad gas estimates. The “RPC” button (chainlist.org) lets you switch to a healthier endpoint in seconds and can save a failed transaction.

Question 6

Which blockchain has the cheapest fees?

Accepted Answer

It changes constantly. Most L2s (Base, OP Mainnet, Scroll…) and recent L1s cost well under a cent per swap, while Ethereum mainnet is usually the most expensive. This dashboard compares 56 chains in real time, in USD.

Question 7

When is the best time to transact?

Accepted Answer

Gas is often cheaper at night and on weekends, but every chain has its own pattern. The “Best time” button shows a 7-day × 24-hour heatmap of gas prices in your local timezone.

Question 8

How does EVMgastracker work?

Accepted Answer

It reads the public RPCs of 56 EVM chains every few minutes, converts fees to USD using each chain's own gas token price, and keeps 7 days of history. No API key, no sign-up, no tracking — free.
