+**Caution:** Ripple provides the [Testnet and Devnet](../../concepts/networks-and-servers/parallel-networks.md) for testing purposes only, and sometimes resets the state of these test networks along with all balances. As a precaution, **do not** use the same addresses on Testnet/Devnet and Mainnet.
