Base gas fees are tiny in dollar terms: on October 29, 2026, a simple transfer cost under $0.001 and a swap about $0.02 in gas on our live check. Gas on Base is paid in ETH. Below: how the fee works, live numbers and how to get ETH if you have none.
Key Takeaways
- Gas token: ETH.
- Transfer: under $0.001 on our check.
- Swap: about $0.02 of gas on a live route.
- No ETH, no transactions: even sending a stablecoin needs a little ETH.
How Base Fees Work
Base is an Ethereum layer 2 built on the OP Stack. Every Base transaction pays two parts: an L2 execution fee (gas used × Base gas price) and an L1 data fee for posting the transaction data to Ethereum. Since Ethereum’s Dencun upgrade in March 2024, that data goes into cheaper blobs, which is why Base fees fell to fractions of a cent.
Live Fees on Base
| October 29, 2026 | |
|---|---|
| Gas price | 0.006 gwei |
| ETH price | $2,309.48 |
| Simple transfer (21,000 gas) | under $0.001 + small L1 data fee |
| Swap (live LI.FI route, USDC to ETH) | about $0.02 |
Gas price from a public Base RPC (eth_gasPrice); swap gas from a live LI.FI route for $100 of USDC. Fees move with demand, so check the wallet estimate before you sign.
L2 Execution Fee vs L1 Data Fee
The execution part is what the Base gas price (in gwei) measures; the L1 data part depends on Ethereum blob prices and the size of your transaction. Wallets show the total. On busy days the L1 part can dominate, but both stay small compared with Ethereum mainnet.
How to Pay Less
- Batch actions: fewer transactions mean fewer fees.
- Avoid peak moments: big launches and market crashes push gas up.
- Keep a small ETH buffer: running out mid-way forces an extra top-up transaction.
- Compare networks: see gas tokens by chain and ETH gas fees.
No ETH on Base?
You cannot pay Base fees with another token. The quickest fix is a one-step swap from a network where you already have funds, straight to ETH on Base, using the widget on this page. Related: crypto bridge fees, how long does bridging take.
