# ZKsync Era

## Definition

ZKsync Era is an Ethereum Layer 2 network using zero-knowledge rollup technology and an EVM-oriented execution environment.

## What it means in practice

Its transactions, balances and fee environment are separate from Ethereum mainnet even though the network is designed to inherit security from Ethereum through its rollup architecture.

## How this concept appears in Terenval Wallet

ZKsync Era is one of the built-in real networks supported by Terenval Wallet.

**Important:** Check network and bridge destination carefully because ETH on ZKsync Era is not the same chain balance as ETH on Ethereum mainnet.
