Question 1

What are Base gas fees?

Accepted Answer

Base gas fees are the transaction costs paid to validators who process and confirm operations on the Base network. As an EIP-1559 compatible chain, Base fees consist of a base fee (adjusted dynamically per block based on network demand) plus a priority tip that incentivises faster transaction inclusion. The Ethereum gas guide walks through how base fee and priority tip combine, using the same model Base inherits. The cost of a standard transfer (21,000 gas) varies depending on current network congestion and token price.

Question 2

How to track Base gas prices?

Accepted Answer

This real-time Base gas tracker shows the current cost of transactions at four priority levels: Low, Normal, High and Max. Network congestion is currently at 10.4%. Base produces blocks every 2s. All data is fetched live and refreshed automatically every few seconds.

Question 3

How much does a swap cost on Base?

Accepted Answer

Transaction costs on Base depend on the operation complexity. A simple native token transfer uses 21,000 gas, while an ERC-20 token transfer requires around 65,000 gas. More complex operations like DEX swaps typically use around 150,000 gas, and NFT mints can use 150,000 gas or more. Use the Base gas fee calculator above to estimate the real-time cost for each operation type at every priority level.

Question 4

How to reduce Base transaction costs?

Accepted Answer

Select "Low" priority when your transaction is not time-sensitive to pay the minimum fee. Transact during off-peak hours when network congestion is lower. You can also compare Base fees with other networks on the multi-network gas station to find the cheapest blockchain for your transaction.
