# Wei

## Definition

Wei is the smallest denomination of ETH, with one ether equal to 10^18 wei.

## What it means in practice

Ethereum protocol values are commonly represented internally as integer wei to avoid floating-point ambiguity.

## How this concept appears in Terenval Wallet

Terenval can display user-friendly ETH amounts while transaction values are ultimately encoded in Ethereum integer denominations.

**Important:** Check units when reading raw transaction data because wei, gwei and ETH differ by large powers of ten.
