In order to do this broken slippage trade that happened with Kyberswap, Most other defi dex will 1) require turning on advanced mode 2) display a warning with confirmation box, or in some cases disallow slippage this high and 3) display a warning confirmation box if the trade moves the price more than 5%.

It is still early days in a lot of ways, but what disgusts me as a web3 developer is seeing tons of underfunded dapps get this right while vc monstrosities like Kyber don’t do the basics.
