Offchain Labs has developed a suite of scaling solutions for Ethereum. This includes Arbitrum, an Optimistic Rollup, that instantly scales apps, reducing costs and increasing capacity, without sacrificing Ethereum's security. Porting contracts to Arbitrum requires no code changes or downloads since it’s compatible with existing Ethereum developer languages and tooling. Arbitrum today is the leading Ethereum scaling solution with dominant market share including hundreds of apps on the platform and over 50% of all rollup liquidity.
