I'd say Uniswap is interesting. That doesn't use an oracle.

  But it also only works with on-chain cryptoassets.

    If you want to work with off-chain things then necessarily your system is going to include off-chain things. I'm not sure of your point here. However, I can think of an exception. Augur is a prediction market that doesn't use a trusted source to resolve bets. It doesn't get a lot of use these days, and probably won't before scaling resolves gas prices, but the bets that have been live on the system have resolved correctly.
