Start with three questions: who controls the assets, how does a trade settle, and what can stop a withdrawal? This guide compares exchange custody, DEX settlement and perpetual-trading risk, then gives you a checklist for reading a venue’s rules.
Educational reading guide. Examples describe mechanisms, not a recommendation to use a venue or trade with leverage.
What an exchange balance represents
An exchange interface can make very different systems look similar. A number shown beside a token might represent a claim against a custodian, collateral deposited into a protocol or an asset controlled by a wallet. The first task is to identify which arrangement applies, who can move the assets and what conditions govern withdrawal.
The U.S. Department of Justice's 28 March 2024 FTX sentencing announcement documents the misuse of customer funds. This historical record explains why custody and accounting deserve scrutiny. It does not, by itself, demonstrate that every decentralized venue is safer or that a later trading-volume increase was caused by FTX.
Use dated legal records precisely
In a separate case, the DOJ's 21 November 2023 Binance announcement recorded guilty pleas and a corporate resolution exceeding $4 billion. That is a dated enforcement event, not a description of every current executive, license or later legal development.
Assessing a current exchange requires current, jurisdiction-specific information. An old penalty alone neither certifies nor disproves its present controls, and a dated enforcement event does not establish the cause of a later market-share change.
DEX settlement changes the risk questions
Using a wallet to authorize a transaction does not mean the assets remain freely spendable in that wallet after deposit. A protocol may hold collateral under contract rules, bridge assets, depend on administrators or use external price inputs. Users need to understand withdrawal conditions and upgrade authority as well as signature control.
Order handling is also distinct from settlement. dYdX Chain's documented design distributes in-memory order books across nodes and reconciles them with committed blocks. Calling a venue “onchain” without identifying this boundary can hide important differences in cancellation and finality.
Perpetuals retain liquidation and deleveraging risk
A perpetual contract creates price exposure using collateral. The venue's margin, funding and liquidation rules matter even when settlement is transparent. As a concrete example, Hyperliquid's liquidation documentation describes mark-price-based margin checks, order-book liquidation and a backstop process. Those are protocol rules, not a promise that a trader can always exit at the screen price.
Its auto-deleveraging documentation also describes closing selected opposite-side positions when an account becomes negative. A profitable position can therefore be affected by a loss-management mechanism. This example illustrates a dependency to investigate, not an endorsement or a ranking of venues.
Read volume figures with their limits
Check the measurement period, the product and whether the service still operates under the same contracts. A platform can migrate infrastructure or stop a service after a measurement period; an old volume figure cannot establish its present availability.
Even with a reliable dataset, notional derivatives volume is not deposited capital or a count of unique traders. A market-share comparison needs matching periods, products and venue coverage. Claims that DEXs matched centralized exchanges in every aspect of usability or survived a stress event better need direct operational evidence.
A practical review can compare custody, withdrawal rights, order cancellation, margin rules, oracle inputs, governance and outage behavior. No universal allocation between CEXs, DEXs and self-custody follows from that comparison; each arrangement creates different responsibilities.
A checklist you can use
| Question | Evidence to look for | What it does not prove |
|---|---|---|
| Who controls the assets? | Custody terms, contract permissions and withdrawal rules. | A balance on a screen does not establish unrestricted access. |
| How does the trade settle? | Order-handling documentation, settlement rules and the role of bridges or administrators. | A label such as “onchain” does not explain every dependency. |
| What happens under stress? | Margin, liquidation, oracle and loss-management documentation. | Transparency does not guarantee an exit at the displayed price. |
| What does the activity figure measure? | Period, product, units and venue coverage for the dataset. | Trading volume is not deposited capital or a count of unique users. |
Reading exercise: imagine two interfaces each show a balance of 1,000 units. One is an exchange balance; the other is collateral deposited in a trading protocol. Before treating either balance as available cash, record who can release it, which withdrawal conditions apply and whether an open position can consume it. If a field is missing from the documentation, leave it unresolved.

- Trace HyperCore, HyperEVM and trading risk.
- Separate stablecoin reserves from your redemption route.
- Calculate how price and fees change a cash-out amount.
Review and correction record
19 October 2026: removed unsupported monthly volume, growth, market-share and liquidation totals; these were not reproduced from primary records with consistent definitions. This is a withdrawal of reliance, not proof that each number was false. The old Vertex volume example no longer supports a current-operation claim. Its original project announcement was unavailable during review, so this article does not certify shutdown completion or any successor product. The FTX and Binance records are used as dated events, not as proof of a causal shift to DEXs.
20 October 2026: reorganized the guide around custody, settlement and withdrawal questions, added a comparison checklist and moved the correction history here. The linked records and the limits of the evidence are retained.
Pause and explain
Does moving a trade from a centralized exchange to a DEX remove all its risks?
Compare your explanation
No. It changes the control and settlement path. Contract permissions, execution, asset behavior, collateral and the exit route still need to be examined. Spot exchange and leveraged trading also involve different exposures.
Take these questions into the current chapter: cost, usability and claims on assets outside the chain.
