# Liquidity Provision Liquidity provision plays a vital role in the Lexer ecosystem since it sets the cap of the total open interest and acts as the counterparty to traders. In return, these **liquidity providers are rewarded with 70% of the trading fee in addition to any potential trader losses.** As Lexer has its unique [Hybrid Liquidity Engine](/innovations-and-mechanism/hybrid-liquidity-engine.md), LPs can choose which engine to provide the liquidity to through the [Smart Router](/innovations-and-mechanism/smart-router.md). For the multi-asset LP engines (CoreCrypto & Arbi), liquidity provision is similar to a blue-chip crypto index with a share of the trading fees and exposure to trader PnL. For the Synthetic LP engine, there is no volatile asset risk as it utilizes stables only, and it also receives a share of the trading fees and exposure to trader PnL. **Fee revenue and exposure to trader PnL are "engine dependent", so providing for one engine will isolate the risk and rewards to the trading from that particular engine.** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
