Analytical Proof & Invariants
Machine PrecisionGoverning Mathematical Formula:
Total Fee = Gas Units × (Base Fee + Priority Fee) in Gwei × (1 ETH / 10⁹ Gwei) × ETH Price
Step-by-Step Mathematical Derivation
1
Effective Gas Price
Total Gwei = Base Fee (24.0) + Priority Tip (2.0) = 26.0 Gwei.
2
EVM Gas Unit Allocation
DEX smart contract swaps (Uniswap v3) require ~150,000 gas units to execute routing, slippage checks, and token balance transfers.
3
Ether Conversion
Fee in ETH = 150,000 units × 26.0 × 10⁻⁹ = 0.00390 ETH.
4
Dollar Valuation
Dollar Fee = 0.00390 ETH × $3,200/ETH = $12.48. Under EIP-1559, 92.3% of this fee (0.00360 ETH = $11.52) is permanently burned from circulation.

Frequently Asked Questions
What is 1 Gwei in Ethereum?
1 Gwei (giga-wei) is 10⁻⁹ ETH (0.000000001 ETH). It is the standard denomination used to quote gas prices on the Ethereum network.
Why do DEX swaps cost more gas than simple ETH transfers?
A simple native ETH transfer between two wallets requires exactly 21,000 gas units. A DEX swap executes multiple storage read/write operations, arithmetic validations, and token allowance updates across smart contracts, consuming 130,000 to 180,000 gas units.
