Layer One DeFi

Definition ∞ Layer One DeFi refers to decentralized finance applications and protocols built directly on the foundational blockchain layer, such as Ethereum or Solana. These applications operate without relying on secondary scaling solutions. They utilize the security and decentralization properties inherent to the underlying mainnet. This category includes core lending, borrowing, and exchange protocols.
Context ∞ News frequently discusses Layer One DeFi in relation to network congestion, transaction costs, and security audits. Debates often involve the scalability limitations of these base layers versus their strong security guarantees. The ongoing development of Layer One blockchains significantly influences the growth and operational capabilities of these foundational DeFi services.
