# Onsen V1

**AMM Mechanism (System)**

Onsen Swap leverages mathematical curves, in combination with Uniswap V2 and Stable pair protocols, to optimize liquidity. Depending on the asset pair, the platform selects the most suitable curve to concentrate liquidity and enhance trading efficiency.

**Token Mechanism (System)**

Onsen uses a dual-token model consisting of the native liquid ON and its escrowed version bON. These tokens provide continuous support for Onsen Farm rewards, with bON being the primary supporter to reduce unchecked emissions and incentivize liquidity while maintaining protocol health.

**Farming** **Mechanism (System)**

The long-term emission strategy of Onsen will concentrate on the LSD track and blue-chip protocols that yield genuine profits. The acquisition of high-quality asset liquidity that generates real profits will be prioritized, as this is crucial for the healthy, long-term development of the protocol and the broader zkSync Era ecosystem. We believe that LSD will drive a new round of DeFi summer.

**Launchpad (System)**

Coming soon
