What Is Base? Coinbase's Ethereum Layer 2 Explained
Base is an Ethereum layer 2 network created by the exchange Coinbase. It aims to make Ethereum cheaper and easier to use, and to bring more everyday people on-chain. This short guide explains what Base is, how it works, and what to watch out for.
The 20-second version
Base is a low-fee Ethereum layer 2 built by Coinbase using Optimism's open-source OP Stack. It settles to Ethereum for security. Notably, Base has no token of its own — fees are paid in ETH.
What is Base?
Base launched in 2023 and quickly became one of the busiest Ethereum layer 2s. It was incubated by Coinbase, one of the largest crypto exchanges, which gives it tight integration with Coinbase's apps and a large built-in audience.
Under the hood, Base is built on the OP Stack — the same open-source technology behind Optimism — and is part of the wider Superchain vision of interoperable networks.
How Base works
Like Optimism and Arbitrum, Base is an optimistic rollup. It processes transactions cheaply off to the side, batches them, and posts them to Ethereum, which acts as the secure settlement layer. We compare rollup styles in optimistic vs zk rollups.
- Built on the OP Stack, so it shares Optimism's design.
- Settles to Ethereum for security.
- No native token — fees are paid in ETH.
What to keep in mind
Base's ties to a large, regulated exchange are a strength for newcomers, but they also mean a single company plays a central role in the network today — something the project says it intends to decentralise over time.
A fair warning
Because Base has no token, beware of scam coins and fake 'Base tokens' promising airdrops. Always verify contract addresses, never share your seed phrase, and only risk what you can afford to lose. This is education, not financial advice.
Key takeaways
- Base is an Ethereum layer 2 built by Coinbase on the OP Stack.
- It's an optimistic rollup that settles to Ethereum.
- Base has no native token — fees are paid in ETH.
- Be wary of scams claiming to offer a 'Base token'.
Frequently asked questions
Does Base have its own token?
No. Base does not have a native token, and fees are paid in ETH. Any coin claiming to be 'the Base token' should be treated with suspicion.
Is Base the same as Coinbase?
No. Coinbase is the exchange that built Base, but Base is a public, Ethereum-based network that anyone can build on or use.
