Polygon PoS mainnet: required vs actual priority gas fees?

You should go with the minimum priority fee of 30 gwei as specified in the documentation. Even though the gas station might show lower values for standard and low fees, it's important to meet the minimum requirement to ensure your transaction gets processed on the Polygon PoS mainnet

Your transaction would get stuck if the priority fee is less than 30 gwei. Even at low, I see the priority fee is above 30 gwei right now.

Make sure to keep track of the current priority fee at the gas station. Though you mentioned using the gas station at https://gasstation.polygon.technology/v2 and sometimes seeing around 29 for standard, it's important to stick with at least 30 gwei as recommended in the docs to avoid long pending transactions.

On the Polygon PoS mainnet, the documentation states that the minimum priority fee should be 30 gwei, but in reality, the actual required gas fee fluctuates based on network congestion. If you're checking the Polygon Gas Station and see lower priority fees listed for standard or low transactions, it means the network isn't experiencing heavy traffic, and you can likely get your transaction confirmed with a lower fee.

That said, I’d recommend setting 30 gwei if you want reliability. Even though you might get away with a lower fee, using the documented value ensures that your transaction isn’t delayed when network activity suddenly increases. If you’re not in a rush, you can experiment with the lower values shown by the gas tracker, but be prepared for possible delays.

I’ve personally tried submitting transactions at lower fees based on real-time gas data, and while they usually go through, there were times when congestion spiked, causing my transaction to stall. If you’re dealing with important transfers, DeFi interactions, or NFT minting, it’s better to follow the 30 gwei guideline to avoid waiting longer than expected. However, if you’re just making a casual transaction and don’t mind some delay, using the lower suggested fee can save some MATIC.

Ultimately, the choice depends on your priorities—speed or cost. If you need certainty, stick to 30 gwei. If you want to save on gas and can wait, go with what the gas tracker suggests.

Not necessarily. The Polygon Gas Station reflects real-time gas fee trends, meaning if the displayed priority fee is lower than 30 gwei, transactions can still be confirmed at that lower rate. However, setting 30 gwei or higher ensures that your transaction gets picked up quickly, especially when network traffic spikes.

So you can try:

• Follow the Gas Station Data – If the standard or low priority fee is below 30 gwei, you can likely set your fee accordingly without issues.
• Use 30 Gwei for Faster Confirmation – If you want consistent transaction speed, stick to the documented 30 gwei minimum, especially if you are processing important or time-sensitive transactions.
• Adjust Based on Congestion – During peak activity, setting a higher priority fee can prevent delays.
