# Optimism

## Definition

Optimism is an Ethereum Layer 2 network based on optimistic-rollup technology and the OP Stack ecosystem.

## What it means in practice

Optimism has separate balances and transaction state from Ethereum mainnet, with bridging used to move assets between network contexts.

## How this concept appears in Terenval Wallet

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

**Important:** Verify the selected chain before sending because an EVM address alone does not tell you whether the intended balance is on Optimism or Ethereum.
