You need a wallet on Polygon PoS and an explorer for that chain, which is not Ethereum mainnet.
What you need before you start
Your wallet shows an estimated fee built from the current Polygon PoS gas price. That estimate is not final, because demand moves the gas price and your transaction's gas use can change.
How to check fees step by step
The explorer lists gas price, gas used, and the total fee. Gas price is what one unit of gas costs, and gas used is how many units the transaction consumed. Total fee is the two multiplied together.
- 1Open a Polygon PoS explorerPick one that names Polygon PoS, then paste your transaction hash from wallet activity into its search box.
- 2Read the two gas numbersBoth appear on the transaction page: the gas price in gwei and the gas used in units.
- 3Multiply the twoDivide the gas price by one billion to get POL, then multiply by the gas used.
- 4Check the statusA confirmed transaction shows a settled fee, and a pending one shows none yet.
After you send: records and checks
Once the transaction confirms, your wallet activity shows the fee it charged. Note it in POL and its dollar value that day, because the IRS treats cryptocurrency as property and paying a fee in POL is generally a taxable disposal. Demand changes the gas price, so check the explorer again before your next confirmation.
