Base ChainArbitrum OneThe flagship L2 chain is decentralized and permissionless, deriving security from Ethereum while leveling up what it can do.
Data AvailabilityArbitrum AnyTrustArbitrum AnyTrust offers best-in-class security, relying on a trust-minimized Data Availability Committee (DAC) which keeps data offchain. By doing so, Arbitrum AnyTrust can provide ultra-low fees for chains that opt-in. If the committee is unable to sign, the chain can still operate by falling back to a standard rollup protocol.
StackOptimism BedrockOP Stack rollups offer Ethereum equivalence, inherited Ethereum security, along with sub-second confirmation times and low, predictable gas fees.
