Oracles

Raydium's AMM uses the pricing curve k=x*y to determine price according to the ratio of tokens in a liquidity pool, and therefore does not rely on an outside oracle at this time for pricing feeds.

This also means that Raydium is not at risk of Oracle manipulation, and with Solana's Proof of Work consensus and high TPS, flash-loan attacks are not really feasible in current conditions.

Similarly goes for front-running of transactions, which is not really possible on Solana at the moment.
