You can use Sepolia PoW Faucet, that just requires Gitcoin Passport with a score >= 2 as of now.
You can easily achieve a passport score >=2, just by connecting some of your socials.
And, then you can start mining Sepolia-Eth easily in no time.
Or, you can use Chainlink faucet to get 0.1 Sepolia-Eth, or any other native testnet token depending on your need (as long as it’s available in the list). They’re not asking for any mainnet funds availability or so.
