Frequently asked questions

Are testnet coins worth anything? Can I sell them?

No. Testnet coins are free, effectively unlimited, and deliberately worth nothing. Anyone offering to buy or sell them, or claiming they will be worth money later, is running a scam. See why testnet coins have no value.

How do I get testnet coins?

The fastest way is a faucet, which gives them away for free. You can also mine them. Start with getting coins from CypherFaucet, or try mining with TestnetPool.

Is this safe? Could I lose real money?

Testnet coins have no value, so you cannot lose money by using them. The one real rule: never paste a real recovery phrase or private key into a testnet tool, and never send mainnet coins to a testnet address. Always generate a fresh, throwaway testnet wallet.

Do I need to install anything?

No. TestnetWallet runs in your browser, and everything on TestnetHub is a web page. Running your own node is optional and only for going deeper.

Which coin should I start with?

Any of them works. Bitcoin has the most tools and the most documentation, Litecoin confirms faster and adds MWEB, and Monero teaches you privacy by default. If you just want to see the whole loop quickly, start with Bitcoin on testnet4 or signet.

Why is my transaction taking so long?

It is probably waiting in the mempool for a block, or its fee is too low. Testnet block timing is also erratic, so waits are normal. See how confirmations work and debugging a stuck transaction.

Can I use testnet coins on mainnet, or the other way around?

No. Each testnet is a completely separate blockchain with its own coins and address formats, so the two never mix. That separation is the whole point. See what a testnet is.

Is TestnetHub official, or run by Bitcoin/Litecoin/Monero?

No. TestnetHub is an independent, open-source educational project, part of the Tech1k testnet ecosystem. It teaches the real protocols but is not affiliated with any of the coin projects.
