Base chain
Coinbase's optimistic rollup built on the OP Stack — fastest-growing L2 by stablecoin yield surface.
Base launched 2023, settles to Ethereum, and inherits security from the OP Stack. Hosts Aave v3, Morpho, Aerodrome, and is the deployment chain for Coinbase-native stablecoin products including USDC and the Coinbase USDC rewards programme.
