So, I just got myself into this Crypto thing, and it’s like a whole new world out here. I’ve been hearing a lot about MetaMask and how people are using it for transactions and all. I know MetaMask is a browser-based wallet used to store Ethereum and ERC-20 tokens. Now, I came across the term Sepolia testnet and I’m a bit confused about it. Is it something like a trial version before making actual transactions on MetaMask? How do I use this testnet on MetaMask? Can anybody please help me out here and guide me through the process? Just keep it simple for a newbie like me.

Sure, I can help with that. The Sepolia testnet is indeed like a trial version of the Ethereum network. It’s used mainly for development purposes, allowing developers to test out their dapps or smart contracts without the risk of losing real Ether if something goes wrong. It’s a safe space where operations can be carried out just like on the live Ethereum network, but with pseudo Ether that has no real-world value.

To use Sepolia on MetaMask, you need to set it up as a custom network. Go to your MetaMask and click on the network dropdown, usually set to ‘Ethereum Mainnet’, then click on ‘Custom RPC’. In the new network form, put in ‘Sepolia’ as the network name, ‘https://sepolia.aragon.network’ as the New RPC URL, ‘100’ as the chain ID, ‘ETH’ as the currency symbol, and ‘https://sepolia.aragon.network’ as the block explorer URL. Once you’re done, hit ‘Save’, and you’re all set to interact with the Sepolia testnet! You can switch between the Sepolia and main Ethereum network in the same network dropdown. Happy experimenting!
