Rubicon Overview ---------------- Rubicon is an onchain order book protocol built on the leading Ethereum L2 networks. On Rubicon, Limit Orders earn fees. When an order is filled, the majority of [protocol fees](https://docs.rubicon.finance/protocol/rubicon-market/fees) are paid directly to the “maker”, the address that placed the order, as a rebate. Maker Rebates compensate traders that provide liquidity on the protocol, helping them cover their transaction fees and the risk of providing liquidity onchain. ![](https://storage.googleapis.com/papyrus_images/37c5c86d0ef759bc2fbe70ea929e7e1cdf24a5b3711d0e9665afd9c456056d41.png) Paying gas fees for every single limit/cancel order can get expensive. To solve this, Rubicon has [Batch Orders](https://docs.rubicon.finance/protocol/rubicon-market/batch-orders), novel order types traders use to **place, cancel, or update hundreds of orders in a single transaction**, limited only by the network’s block/transaction gas limit. By batching many orders into one transaction, traders can prorate transaction fees across multiple orders, reducing their **cost per order**. By saving on transaction fees with rebates and batch orders, Rubicon market makers can actively update their onchain positions as prices change on centralized exchanges. This means better returns for liquidity providers, and lower spreads/better rates for traders!
