**Simple summary**

We are excited about CoW Swap’s expansion to L2s!

WOOFi’s sPMM liquidity, deployed on 9 EVM L2s and alt L1s, provides superior pricing on major assets by simulating CEX orderbook liquidity on-chain. It has processed $14.5b volume across all the networks ($8.3b alone on Arbitrum).

WOOFi’s proactive and faster price discovery powered by its high frequency on-chain oracle will help solvers improve the on-chain price execution for CoW Swap users. Another unique advantage is we provide a 20% swap fee rebate to solvers, which can be claimed as additional revenue and allow solvers to provide even better pricing.

**Motivation**

Integrating WOOFi sPMM liquidity will bring the following benefits to both solvers and users:

- 20% of the swap fee can be rebated to solvers in stablecoins, which solvers can choose to reflect all or partially in the quotes
- No off-chain elements in the integration - better execution guarantee and easier integration than off-chain RFQ
- Price and liquidity simulating CEX orderbook regardless of which network it’s on - ensuring users get high quality execution for majors e.g. WBTC, ETH, native gas tokens
- Arbitraging opportunities with AMMs (passive price discovery)

**Specification**

Onchain methods are available for checking the token list, query swap price, poolsize, and executing swaps. Please see details in the following link
