Testnet
A non-production blockchain network where developers test wallets, contracts, and upgrades using coins with no intended market value.
A testnet is a separate network that imitates many mainnet rules while using distinct coins, addresses, peers, and chain history. It lets developers and learners test software without risking real funds.
Testnets are useful for integration testing, smart contract rehearsals, protocol experiments, and education. They are not perfect copies of mainnet: liquidity, validator behavior, hash rate, congestion, and tooling support can differ substantially.
Testnet coins should be obtained from faucets or mined in a test environment, never purchased as an investment. Keep test wallets clearly labeled and avoid reusing mainnet seed phrases or private keys in experimental tools.
