Frequently Asked Questions

Does Base have a token?
No. Base does not have a native governance or utility token. Coinbase has stated there are no plans to launch a Base token. ETH is used for gas fees on the network.
Is Base controlled by Coinbase?
Base was incubated by Coinbase and currently uses a centralized sequencer operated by Coinbase. Over time, Base plans to decentralize as part of the Optimism Superchain initiative.
Which L2 has more DeFi protocols?
Arbitrum currently has a larger and more mature DeFi ecosystem. However, Base is growing rapidly and has attracted significant TVL, particularly through protocols like Aerodrome.
Are fees the same on Base and Arbitrum?
Both have very low fees, especially after EIP-4844 reduced data posting costs. Fees vary slightly depending on network congestion but are broadly comparable.
Can I use MetaMask on both?
Yes. Both Base and Arbitrum are EVM-compatible L2 networks. You can add either chain to MetaMask and use the same Ethereum address on both.
