7 proven methods to lower Polygon gas fees:

1. Set manual gas prices in MetaMask. Enable Advanced Gas Controls. Set Priority Fee to 25 to 30 Gwei. Cuts fees by 50 to 80%.
2. Transact during off-peak hours. Fees lowest during late-night UTC and weekends.
3. Batch multiple operations. Combining 5 operations into one transaction reduces fixed overhead by up to 80%.
4. Use efficient RPC endpoints. Switch to Alchemy, QuickNode, or Infura for accurate gas price reads.
5. Avoid peak congestion events. Delay non-urgent transactions during NFT mints and DeFi launches.
6. Use a gas price oracle. Integrate a gas oracle API to fetch optimal prices automatically.
7. Fix stuck transactions immediately. Replace stuck transactions using the same nonce with a higher gas price to unblock your wallet.
