Financial services: lending, borrowing, fractionalization, using oracles to peg tokens to real-world assets like USD and EUR, equities, perhaps eventually physical goods like gold bullion, high-end liquor, physical property. Payments: transfers, escrow, crowdfunds, auctions, charitable giving, royalty splitting. Digital property: name aliases, user accounts, single sign on. See Lens Protocol and Farcaster which build on these ideas. Art and collectibles, obviously. See Art Blocks, Foundation, SuperRare. Experimental protocols and games like PoolTogether, 0xMonaco CTF, Dark Forest. Privacy preserving payment rails like Aztec, Polygon Nightfall. Game economies like Skyweaver. Once Ethereum development is a little further along and L2 landscape more mature, there will be a lot more applications that can start to be built on top of the ledger. Think higher-level abstractions like ticketing, in-app and in-game assets, better payment processors. These would not use Ethereum mainnet directly for every transaction, but instead use a higher-level abstraction like a zkEVM rollup or validium.
