# Swap

**Classic Swap:** Emulates the familiar, full-range pool model for a traditional DEX experience. It’s fully permissionless, supporting both volatile (vAMM) and stable (sAMM) pools, and simplifies token trading and liquidity provisioning for users.

**Concentrated Liquidity (Fusion) Swap:** This swap type leverages our FUSION model, combining concentrated liquidity with ALM strategies to optimize liquidity utilization and deliver improved price efficiency for traders. Where applicable, swaps are also routed through manual CL positions, further enhancing liquidity access. For more on concentrated liquidity, please see our dedicated CL page.
