What is Wei and Gwei?
Wei is the smallest unit of an EVM coin (10⁻¹⁸), and Gwei is one billion wei (10⁻⁹), the unit gas prices are usually quoted in.
EVM chains track balances in integers to avoid rounding errors, so one MON equals 10¹⁸ wei. Most tokens use 18 decimals for the same reason.
Gas prices are small, so they're shown in gwei (1 gwei = 1,000,000,000 wei) for readability.
