Polygon zkEVM offers **predictably low gas fees**—typically **$0.01–$0.10 per transaction**—thanks to its ZK-rollup design, but costs vary by activity:  

1. **Bridging** – Ethereum L1→zkEVM transfers incur Ethereum’s base fees (~$2–$10), but zkEVM-side tx costs are minimal.  
2. **Swaps/LP Actions** – DEX trades (e.g., QuickSwap) average **$0.02–$0.05**, cheaper than Polygon PoS.  
3. **Contract Deploys** – Higher complexity = higher fees (e.g., NFT mint ~$0.15), still 10x cheaper than Ethereum.  

*Pro Tip*: Fees spike during Ethereum congestion—schedule zkEVM interactions during **UTC midnight–6am** for optimal rates.
