What is Mainnet and Testnet?
Mainnet is the real blockchain network used for “actual” transactions with “monetary value”, your wallet is set to Mainnet by default. Testnet on the other hand is a testing network that runs the same protocol as Mainnet does and is used for testing purposes. It allows you to experiment without having to use valuable coins on the main network (Mainnet).
Testnet coins are distinct from actual coins, they do not have any monetary value and cannot be used to pay transactions. Although similar, the testnet and mainnet are not compatible. This means that you cannot use actual coins on the testnet, and you cannot use testnet coins on the mainnet.
On the Crypto.com Onchain app, we currently support CRO testnet and ETH testnets -
CRO Testnet: Croeseid testnet is a testnet on the Crypto.com Chain—a secure, low-cost, and open-source blockchain powered by the Cosmos SDK.
Cronos Testnet: Powered by Ethermint, Cronos Testnet is the trial version of Cronos Chain—allowing rapid porting of apps and smart contracts from Ethereum. You can receive a test CRO to transact on the Cronos Testnet using the TCRO Faucet.
ETH Testnet: ETH Testnet is a simulation blockchain that allows you to trial Ethereum transfers and smart contracts without using real tokens. We support Ropsten, Kovan, Rinkeby and Goerli ETH testnets on the Crypto.com Onchain app

How do I know if I am using testnet in my Crypto.com Onchain app?
When you are using testnet, there will be a blue indication bar at the top of the screen when you are navigating the app. All transactions and contract calls will be conducted on testnets.
As mentioned, testnet wallets do not involve real currency, and there is no way to turn testnet coins into cryptocurrency with real financial value.
How can I receive testnet coins?
Faucets are a popular way to get testnet coins. They are web apps that were developed to help users to get tokens on testnet for experiments. The two most popular Ethereum testnets are (i) Ropsten, which uses PoW (Proof of Work), (ii) Rinkeby, which uses PoA (Proof of Authority). Here are some faucets to receive testnet coins on ETH & CRO testnets -
CRO - Croeseid: | ETH - Kovan:
|
CRO - Cronos: | ETH - Goerli: |
ETH - Ropsten:
| ETH - Rinkeby: |
You’ll be able to also find the latest available faucets with a simple web search for "testnet faucet".
How can I swap testnet coins?
Unfortunately, we currently do not support the swapping of testnet coins on the Crypto.com Onchain App. Our team is working hard to support more DApps on the app. Stay tuned for our service updates and product offerings by subscribing to our email updates from Home Screen > Explore or Settings > Account > Notifications.
