Testnets are test blockchain networks that act and perform similarly to the main Ethereum network, without requiring users to spend actual ether.
Manifold Studio is the only complete end-to-end contract deployment and token minting platform that provides creators the ability to deploy and mint NFTs to testnets before publishing directly to mainnet. This allows users to experiment with creations more cheaply and preview work completely before going live on mainnet.
To deploy contracts and mint tokens on Sepolia, you will need Sepolia ether. You can use public Sepolia faucets to claim a nominal amount of ether to complete transactions on the Sepolia test network.
