[3/n] My own understanding of "slippage"
1️⃣ What is slippage?
⓵ In a DEX, slippage refers to the difference between the expected transaction price and the actual execution price.
-> In other words, I originally wanted to buy a coin for 1U, but because of excessive slippage (20%), it might be sold for 1.2U, which means I overpaid.
⓶ You can learn more about Uniswap and automated market makers (AMMs) on YouTube.
-> Uniswap is the pioneer of DEXs.
2️⃣ Is it better to set a larger or smaller slippage setting?
⓵ Assume that the slippage setting is larger (if you're in a hurry to buy or sell, set it).
-> The advantage is that it makes it much easier to execute.
-> The disadvantage is that you might overpay and increase the risk of a MEV attack.
⓶ Assume that the slippage setting is smaller (if you're not in a hurry and don't want to lose money, set it).
-> The advantage is that it's less likely to overpay.
-> The disadvantage is that the transaction might not go through.
3️⃣ There are also some other key points to consider, such as when chains are congested, when unpopular coins have poor liquidity, and when there are MEV attacks.
4️⃣ The above is my personal understanding.
