Frequently Asked Questions
Everything you need to know about L2 gas fees
What is gas fee on Base/Arbitrum?
Gas fee is the transaction processing cost on Ethereum L2 networks. Base and Arbitrum use ETH for gas payments, but fees are significantly lower than Ethereum mainnet — typically 10-100x cheaper.
When is the best time to trade with low gas?
Gas prices fluctuate throughout the day. Generally, off-peak hours (UTC 2:00-6:00) have the lowest gas. Our AI tool analyzes real-time data to recommend the best trading windows.
How accurate is the fee calculator?
The calculator uses standard gas estimates for common transaction types. Actual costs may vary slightly depending on contract complexity and network congestion. Always verify on-chain before transacting.
Why are L2 gas fees cheaper than Ethereum?
L2 networks batch transactions and post them to Ethereum mainnet as a single compressed transaction. This shared cost model dramatically reduces per-user fees while maintaining Ethereum security.
Is it safe to use this tool?
Yes. This tool only reads public blockchain data. It does not connect to your wallet, execute transactions, or handle any funds. It is purely informational.
Why is Base gas so high today?
Base gas fees spike during periods of high network activity, such as popular NFT mints, token launches, or heavy DEX trading. When demand exceeds block capacity, the priority fee rises. Check our real-time tracker and AI advisor to see if current fees are elevated relative to the 24h average.
How do I reduce gas cost on Base?
Transact during off-peak hours (typically UTC 2-6 AM), use a wallet that supports EIP-1559 priority fee estimation, batch multiple operations into a single transaction when possible, and avoid transacting during known high-traffic events. Our AI advisor analyzes real-time patterns to suggest the cheapest windows.
What is the base fee on Arbitrum?
Arbitrum's base fee consists of an L1 component (covering data availability on Ethereum) and an L2 component (for execution on Arbitrum). The L1 portion fluctuates with Ethereum gas prices, while the L2 portion depends on Arbitrum's own congestion. This is why Arbitrum gas can sometimes appear higher than expected during Ethereum L1 gas spikes.
Can I use this tool on mobile?
Yes, L2 Gas Tracker is fully responsive and works on all mobile browsers. The interface adapts to small screens, and all features — gas tracking, AI advisor, fee calculator — are available on mobile devices with the same real-time data.
