How this estimate works
Gas units × (next-block base fee + observed median priority fee). Contract calls need a wallet gas estimate.
Fiat fee = native network fee × native coin spot price. Fee-to-amount ratio = fiat fee ÷ transaction value × 100. A $2 fee on a $20 transfer consumes 10%. Use this ratio to assess small transfers. Fees can change before confirmation. Exchange charges, swap fees, slippage and taxes are excluded. No wallet connection or transaction execution is required.
