scroll sepolia should be available as a chain from viem/chains here.

if we have a test logo let's use that instead of DAI to not mislead the user

hey @bhargavaparoksham - running into a few issues:

• I'm not able to apply to a round on Scroll, and it looks like it's due to a LIT error:

• The Builder "My Projects" page generally takes a really long time to load, and also seems to be missing Scroll Sepolia projects

[vacekj]

scrollTestnet is ambiguous as a chain name, since there was previously a scroll alpha testnet, and there will be new testnets in the future. let's call it scrollSepolia to disambiguate.

closing for now since LIT doesn't support scroll testnet
