Do simple settings like price limits help regular people avoid bad crypto trades?
Research question: What simple settings and habits (such as slippage limits and checking transaction details) can an ordinary person use on a decentralized exchange to avoid bad trades, and do they help?
The records show that traders can set a gas price, a slippage limit, and an expiration time to manage their trades on decentralized exchanges 12. A slippage limit is one of the defenses proposed against sandwich attacks, which limit price impact alongside slippage 13. Private transaction submission reduces the attack surface compared with public-mempool chains, but it does not eliminate sandwich exposure entirely 15, and one bot's sandwich attacks on Base were still attributed to transaction-pool leakage before inclusion 16. The facts do not measure how much these settings reduce losses for an ordinary user, so their benefit is only partly established. The newest fact is from 2026 151617.

The paper states that, for a trader, slippage corresponds exactly to the AMM's impermanent gain, meaning the trader's price impact is the mirror image of the pool's impermanent loss.

In a Constant Sum Market Maker (CSMM), the constant price reduces slippage, which is a useful feature for trading tokens with stable relative prices.

Arbitrage activity can entirely drain the liquidity pool of a token in a Constant Sum Market Maker (CSMM) because the constant price cannot respond to external market pressure.
"The main point we wish to make here is that a CSMM functions poorly as a decen- tralized exchange because arbitrage activity can entirely drain the liquidity pool of a token, and the simple x y k case suffices to show that."Automated Market Makers and Decentralized Exchanges: a DeFi Primer (2020)

In a Constant Product Market Maker (CPMM), the price changes every time the reserves change, even if by a small amount, due to the varying slope along the level curve.
"One of the features of a CPMM (and a CMMM) is that along a particular level curve, say k0 in Fig. 4, the slope varies at every point, and consequently the price changes every time the reserves change, even if by a small amount."Automated Market Makers and Decentralized Exchanges: a DeFi Primer (2020)

Arbitrageurs can exploit price differentials between an external market and an AMM to realize risk-free profits, which eventually eliminates the opportunity as prices equalize.
"An arbitrageur could buy X in the exter- nal market for 49.9 and sell it in the AMM for 50.0 Y , thereby making a profit of P Y/X M Y/X 50.0 49.9 0.1 units of Y per unit of X ."Automated Market Makers and Decentralized Exchanges: a DeFi Primer (2020)

Wallet interfaces automatically suggest an optimal gas price based on network activity to balance execution probability and cost, though most users accept the median price.
"Wallet interfaces automatically suggest an optimal gas price, depending on the current levelofnetworkactivityandbasedonthetrade-offbetweentheprobabilityofexecution within the next few blocks and the cost.

Gas fees on decentralized exchanges are fixed costs that do not scale with the dollar value of the transaction, meaning their relative impact decreases for larger trades.

Transaction costs on DEXs include slippage (price impact), exchange fees, and gas fees, which are distinct from the costs on centralized exchanges that primarily involve spread and commissions.

Users prefer centralized exchanges over decentralized ones because CEXes do not have a slippage mechanism, ensuring price consistency and preventing financial losses from price fluctuations during the trade.
