Academy Series #6: Try the Web3 in a safe environment with Testnets
Whenever we speak about applications in a blockchain (Ethereum, BSC, Polygon, Polkadot, Solana, etc.) we are usually referring to applications that are deployed on the so-called MainNet of that blockchain.
However, all of these blockchains also have parallel instances called Testnets. These are testing environments used to test applications and smart contracts before they go fully live. As the name says it’s particularly useful for testing, and they are already extensively used by development teams.
