zkLink is a trading-focused multi-chain L2 network with unified liquidity secured by ZK-Rollups. zkLink makes it possible for liquidity pairs to be made of native tokens from separate chains, and of any type, such as ETH-SOL, UNI-CAKE, USD-XXX, and many more. Multi-chain Trading Curves

*   UNI V2: Constant product curve
    
*   UNI V3: Concentrated liquidity model
    
*   [Curve.fi](http://Curve.fi): Optimized stableswap curve Massive Liquidity Pool A better swap experience enabled through deep unified stablecoin liquidity.
    

Only one liquidity pool is needed for each token, no matter the different chain origin (e.g. USDC-Solana vs. USDC-Ethereum). High Capital Efficiency A higher utilization rate while trading on the zkLink L2 network.

zkLink merges stablecoins from different chains, so traders only need to hold a short list of stablecoins. [https://zk.link/](https://zk.link/) [https://zklink.crew3.xyz/invite/LLwhquCwkuG5K9yL99yCl](https://zklink.crew3.xyz/invite/LLwhquCwkuG5K9yL99yCl)
