Arbitrum is an L2 scaling solution for Ethereum, offering a unique combination of benefits:

• Trustless security: security rooted in Ethereum, with any one party able to ensure correct Layer 2 results

• Compatibility with Ethereum: able to run unmodified EVM contracts and unmodified Ethereum transactions

• Scalability: moving contracts’ computation and storage off of the main Ethereum chain, allowing much higher throughput

• Minimum cost: designed and engineered to minimize the L1 gas footprint of the system, minimizing per-transaction cost.

Some other Layer 2 systems provide some of these features, but to our knowledge no other system offers the same combination of features at the same cost.
