I am learning more about the blockchain so I just started a tutorial on Freecodecamp, in the following video I need to test Ethereum from Rinkeby authenticated Faucet, I did the following step but showed an error. can anyone help?
It's showing an error because Rinkeby Testnet is almost deprecated. Check this warning. Migrate your contracts and deploy new ones on Goerli or Sepolia. The only two testnets, developers will maintain after the merge.
Use Goerli from now on, It is the most recommended testnet rn. Goerli Testnet Faucet: https://goerlifaucet.com/
FYI Goerli is officially the only Ethereum testnet, Rinkeby and all other testnets are deprecated. +1 for https://goerlifaucet.com
