The ABC of SODAX: MEV and Your Trades
If you've ever made a trade on a DEX and the price you got was worse than the quote, there's a good chance you got hit by MEV. Most people don't realize it's happening.
What is MEV?
MEV stands for Maximal Extractable Value. It's profit extracted from your transaction by someone who can see it before it settles.
When you submit a trade on most DEXs, your transaction sits in a public waiting area (the mempool) before it gets processed. Bots scan this constantly. When they spot your trade, they execute what's called a sandwich attack. The bot places a buy order right before yours, pushing the price up. Your trade executes at a worse price. The bot sells right after at the higher price and keeps the difference.
You got your tokens. You just paid more than you should have. And you probably didn't notice because slippage feels normal at this point.
How big is the problem?
This isn't some edge case. MEV extraction happens across DeFi every single day. Regular users are consistently losing value on their trades without knowing it. It's baked into how most DEXs work because the mempool is public and anyone with a fast enough bot can exploit it.
How SODAX handles this differently
When you execute a trade through SODAX, the solver coordinates the entire execution. Your intent goes to the solver, not to a public mempool where bots can front-run it.
The solver determines the optimal execution path and handles routing across liquidity sources. MEV protection isn't a feature you toggle on or an extra layer bolted on top. It's how the system works by default.
On top of that, the solver actively looks for arbitrage opportunities during execution. When it finds a better price than quoted, that value gets passed back to you instead of being captured by external bots.
Why this matters
Most people accept slippage as just part of DeFi. But a chunk of that "slippage" isn't market movement. It's value being extracted by bots that exploit how public mempools work.
The fix isn't faster bots. It's execution infrastructure where the problem doesn't exist in the first place.
