## Layer 3 Technology

Layer 1 is based on Ethereum. Ethereum builds a solid foundation, ensuring unparalleled security and decentralization.

Arbitrum acts as Layer 2, optimizing scalability, reduces costs and increases speed by processing transactions off-chain.

Built on Rollup architecture, DeriW inherits Ethereum's security while seamlessly integrating Layer 3 applications with Layer 2 infrastructure to ensure complete transparency of on-chain data.
