Arbitrum

Arbitrum enhances Ethereum's efficiency as a Layer 2 scaling solution, ensuring swift smart contract execution while slashing transaction expenses. This Layer 2 innovation optimizes Ethereum's foundational Layer 1 by entrusting intricate tasks like transaction handling and data storage to a secondary chain. Essentially, while the Layer 2 chain runs the smart contract, Layer 1 conserves the data. Arbitrum adeptly manages and batches Ethereum transactions, alleviating main network bottlenecks.
