On a broker app your order executes inside a private system you must trust; on a DEX it is a public contract call anyone can audit — custody, transparency and recourse are the real differences.

When you buy crypto on a broker app like Robinhood, you are using a custodial service: the company executes the trade through its own systems and holds the asset for you (unless you later withdraw to your own wallet where supported). It is genuinely convenient — card payments, no gas, familiar UX — and for many people it is the right on-ramp. What you give up is verifiability: execution happens inside a private system, and your recourse is trusting the company and its regulators.

On a decentralized exchange the entire trade is a public transaction: your wallet signs it, a smart contract executes it against pool liquidity, and the result — price, route, fees — is permanently readable by anyone. Custody never leaves you. The trade-offs run the other way: you manage your own keys, pay gas, and face DeFi-native risks like thin liquidity and scam tokens.

## The comparison that matters: verifiability

The deep difference is not fees — it is WHO CAN CHECK. A broker's execution quality is asserted in disclosures; a DEX's execution quality is a public record you can audit yourself. BlazePhoenix pushes that to the limit: even the QUOTE is computed on-chain by the same contract that executes, the minimum output is enforced by the contract (the iron floor), and any execution surplus is returned to you — all of it verifiable per-trade from the transaction itself.

Honest guidance: if you want simple exposure with zero self-custody responsibility, a regulated broker is a reasonable choice. If you want to own the asset, verify the execution, and access tokens brokers never list — that is what a DEX is for. Many people use both; the mistake is not knowing which trade-offs you are holding.

**Verify it yourself:** after any DEX swap, open the transaction on the block explorer — route, amounts and fees are all there; try requesting the same audit trail for an in-app broker trade
