Gas Fee Visualizer

Real-time Ethereum Gas Prices

Track the current gas fees on the Ethereum network to optimize your transaction timing and save costs.

Understanding Ethereum Gas Fees

Gas fees are the fuel that powers the Ethereum network. Learn how they work, how EIP-1559 changed the market, and how to optimize your costs.

What is Gas?

Gas is a unit that measures the computational effort required to execute specific operations on the Ethereum network. Since each Ethereum block has a limited size (gas limit), users must pay a fee to incentivize validators to include their transaction.

EIP-1559: Base Fee vs. Priority Fee

Base Fee: The minimum fee required to be included in a block. This fee is determined by the network protocol based on congestion and is burned (removed from circulation).

Priority Fee (Tip): An extra fee paid directly to the validator to prioritize your transaction. During high congestion, you may need a higher tip to jump the queue.

Gwei Explained

Gwei is the standard denomination for gas prices. 1 Gwei = 0.000000001 ETH (10^-9 ETH). A transaction fee is calculated as: Gas Limit × (Base Fee + Priority Fee).

Frequently Asked Questions

Gas fees spike when network demand exceeds the block capacity (15 million gas target). When everyone wants to trade a hot NFT collection or token at once, the Base Fee increases exponentially to dampen demand.

Historically, weekends and early mornings (UTC) often see lower congestion. Use this visualizer to spot trends and wait for a dip if your transaction is not urgent.

Your transaction will sit in the 'Mempool' (pending pool) until network fees drop to your level. If they never drop, it might be stuck indefinitely until you 'speed up' (replace) the transaction with a higher fee.

No. Sending $1 million in ETH costs the same gas fee as sending $1. However, complex contract interactions (like swapping on Uniswap) cost more gas than simple transfers because they require more computation.

L2 networks (like Arbitrum, Optimism, Base) process transactions off-chain and bundle them together into a single proof submitted to Ethereum Mainnet. This splits the L1 gas cost among thousands of users, drastically reducing individual fees.
