What is Arbitrum?

Arbitrum is an EVM-compatible optimistic rollup protocol managed by on-chain Ethereum contracts.

Arbitrum uses a technique called optimistic rollup, which means that it executes transactions on a layer 2 network and periodically submits proofs to the Ethereum mainnet. This way, it can achieve higher throughput and lower fees than the Ethereum mainnet, while still inheriting its security and interoperability. Arbitrum is managed by on-chain Ethereum contracts, which ensure that the layer 2 network follows the rules and can be challenged if needed.

Take a look at our Arbitrum Documentation page to start working with the Arbitrum protocol.
