FAQ

Why should smart contracts store values in wei?

Wei avoids floating-point errors by representing ETH amounts as integers, which is the safe and standard on-chain pattern.

Why is gwei shown so often in wallets and explorers?

Gas fees are typically priced in gwei because it keeps fee values human-readable while preserving enough precision.
