Wei
The smallest denomination of Ether, with 1 ETH equal to 10^18 wei for exact integer accounting.
Wei is Ethereum's base unit for representing Ether amounts as integers. Using wei avoids floating-point rounding errors in balances, gas fees, and smart contract calculations.
Users often see gas prices in gwei, where 1 gwei equals 1,000,000,000 wei. Wallets convert between ETH, gwei, and wei for readability.
