# Testnet

## Definition

A testnet is a blockchain environment designed for development, experimentation or testing where tokens generally do not represent the same economic asset as mainnet coins.

## What it means in practice

Testnets can reset, change rules or use faucets to distribute testing tokens.

## How this concept appears in Terenval Wallet

Terenval includes selected test networks such as Ethereum Sepolia, Base Sepolia and Bitcoin Testnet4 for supported testing flows.

**Important:** Testnet tokens should not be sold as if they were mainnet assets of the same name.
