Many financial technology firms and crypto exchanges have noted Coinbase's success with Base, its layer-2 blockchain, and decided to work with layer 2s themselves or build their own.

Neutral DeFi protocols that others can easily build on top of are a better path to scale than giant on-chain brokers or funds such as Aave or Compound.
