Arbitrum Chain

Definition

The Arbitrum Chain is a prominent Layer 2 scaling solution operating on top of the Ethereum blockchain. It enhances transaction throughput and reduces fees by processing transactions off-chain using optimistic rollup technology. This method bundles multiple transactions into a single batch, submitting a cryptographic proof to the Ethereum mainnet. Consequently, Arbitrum significantly improves the efficiency and scalability of decentralized applications and smart contracts.
