everyone preaches "not your keys not your coins" but nobody applies the same logic to how their trades get executed

We all learned the self-custody lesson. mt gox, ftx, celsius, voyager. keep your keys, don't trust exchanges with your funds. fine, most of us got that memo.

but here's what I don't get. the same people who would never leave $10k on coinbase will happily send a market order into a DEX where:

* bots can see your trade before it executes and sandwich you
* the matching engine is a black box you can't audit
* the sequencer or validator set can reorder transactions however they want
* there's zero proof that your trade was executed fairly

we moved our custody off-chain but we still trust execution completely. it's like keeping your cash in a personal safe but handing it to a stranger every time you want to buy something and just hoping they give you the right change.

self-custody should mean more than just holding your keys. it should mean verifiable execution. you should be able to prove that your order was matched correctly, that nobody front-ran you, and that the sequencing was fair. the technology for this exists now (ZK proofs can verify order book state transitions) but almost no one is talking about it.

we went from "trust the exchange" to "trust the DEX" and called it progress. it's better, sure. but it's not the finish line.

What would it take for you to trust on-chain trading the same way you trust self-custody? genuinely curious.
