You might have heard of testnets without knowing what they really are and some of might be wondering should you be doing them? If that is the case then you have come to the right place.

What Are Testnets and Are They Worth Doing?

Yes, we think so! But will you agree with us? Let's dive in first and see what the fuss is about.

In the world of blockchain and cryptocurrency we have mainnets and testnets.

Mainets is the shortened version of main blockchain networks, these are the real deal by the way.

Testnets is short for test networks and they mimic the functionality of a main blockchain network (mainnet). and generally work with free cryptocurrency!

In a nutshell think of testnets being like a sandbox where developers, enthusiasts and users (yes that is you and me) can experiment with blockchain protocols without risking real money or assets. Because let's face it nobody likes the risk of losing their money!

What Are Testnets?

Right then, so a testnet is a parallel version of a blockchain network (mainnet) and is designed for testing and development.

When a new cryptocurrency or decentralized application (dApp) is being built, (responsible) developers need a safe space to trial features, fix bugs, and ensure everything works smoothly before launching it on the mainnet.

Remember on a testnet, test tokens are used and not real tokens so you won't in theory lose any real token!

These test networks replicate the mainnet's rules and mechanics but operate with "fake" or test tokens that hold no real-world value.

How Do You Participate?

Participating in a testnet is surprisingly easy, it is usually fun and often rewarding financially (more of that later)!

Generally you’ll need at least .... a crypto wallet, a bit of technical curiosity, and a link to the testnet.
Here’s a simplistic view of what you'll need to do to participate:

• Find a Testnet Opportunity: Many blockchain projects announce testnet phases on their websites, Discord servers, or social media. Look for terms like "testnet launch" or "incentivized testnet." We at MMO do keep a list of testnets that we are working on. Infact we shall share a tutorial for MONAD in the near future.
• Set Up a Wallet: Configure your wallet to connect to the testnet network (e.g., switch MetaMask to Sepolia). Before you do start on your testnet journey you should only use dedicated testnet wallets. You do not want your real funds in a testnet wallet. Security is paramount, and we do not want you to fall victim of a scam or wallet drain.
• Get Test Tokens: Most testnets provide faucets—tools that dispense free test tokens. You will need to request them via a website or Discord bot.
• Follow Instructions: Projects usually ask participants to perform tasks like sending transactions, staking tokens, or testing dApps. Feedback is often encouraged.

Are They Worth Doing?

Whether testnets are worth your time depends on your goals. For developers and tech enthusiasts, they’re invaluable for learning blockchain mechanics, coding smart contracts, or understanding networks hands-on—without spending a penny.

For casual users, the appeal often lies in incentivized testnets, where projects reward participants with real tokens, airdrops, or early access to their ecosystem once the mainnet launches. In other words you get an incentive for participating.

What Can You Earn?

Earnings vary widely. Some testnets offer nothing beyond experience, while others provide tangible rewards. For instance, successful participation in past testnets like Aptos or Sui led to airdrops worth hundreds or thousands of dollars in mainnet tokens. However, rewards aren’t guaranteed, and the value depends on the project’s success. Time investment can range from a few hours to weeks, so weigh the effort against potential gains.

Do You Need Crypto to Start?

No! That’s the beauty of testnets. Since test tokens are free via faucets, you don’t need to own cryptocurrency to join. All you need is a device, internet, and a willingness to experiment.
Whilst you don't need any funds to start, sometimes the developers reward you more if you do have some funds in your wallet. Showing you have skin in the game can bring more rewards!

The Verdict

Testnets are a low-risk, high-reward way to dip your toes into blockchain. If you’re curious, enjoy learning, or want a chance at early crypto rewards, they’re absolutely worth trying.

Just don’t expect instant riches—think of it as planting seeds for future opportunities.

Beware the scams

If it seems to be too good to be true, then it usually is... In other words ... The same principle applies for entering testnets.

Our tips at MMO:

• Create and use testnet dedicated accounts and wallets.
• Don't click external links unless you are 100% sure they are legitimate.
• Use wallet guards before signing transactions.
• Use revoke.cash to revoke authorizations when you are finished.
