On a centralized exchange (CEX), your collateral is held by the exchange. On an on-chain perp DEX, it stays in your own wallet until you deposit it into a smart contract — and you can withdraw it at any time, without asking anyone's permission. That single structural fact shapes everything else: counterparty risk, transparency, what assets you can trade, and who can access the market. This article breaks down each dimension so you can evaluate which model fits your needs. > **NFA.** Perpetual futures are leveraged products that carry a high risk of loss. Availability varies by jurisdiction. ### At a Glance: The Core Comparison

### Custody: The Structural Divide On a CEX, you deposit funds into an account the exchange controls. You trust the platform to hold your money honestly, execute your trades accurately, and return your funds when requested. When that trust breaks — as it did with FTX in 2022 — users have no on-chain recourse. The exchange held the keys; the exchange decided what happened next. On an on-chain perp DEX, you hold your private keys. When you trade, a smart contract locks only the margin you explicitly deposit for a given position. Outside of that, nothing leaves your wallet. If you choose to stop trading, you withdraw — the protocol cannot prevent it. This is the difference between **institutional custody** (you trust someone else) and **self-custody** (you trust math and code). Both carry risk — a CEX can fail, and a smart contract can have vulnerabilities — but the nature of the risk is different, and the degree of control is not. ### Transparency On a CEX, you see your account balance and trade history as reported by the exchange. You cannot independently verify that the exchange's stated reserve matches reality, or that your reported price is accurate, or that liquidations happened when claimed. Exchanges can be audited, but audits lag real time. On a DEX, every order, fill, funding payment, and liquidation is a blockchain transaction — publicly indexed, timestamped, and verifiable by anyone. You can audit the protocol's total open interest, check any position's margin level, and verify your own trade history against the chain. This is what "trustless" means in practice: you don't need to trust a company's reporting because the ledger is open. ### Access and Account Requirements CEXs require account creation, identity verification (KYC), and in some cases geographic restrictions determined by the platform's licensing. For many users globally, this creates friction or outright barriers. A perp DEX has no concept of an account in the traditional sense. You connect a wallet address — that address *is* your account. No email, no password, no document uploads. Any wallet anywhere in the world can interact with the protocol's smart contracts. Note: on-chain perp platforms may still apply geographic access controls at the front-end (web interface) level to comply with local regulations. Check a platform's terms of service for your jurisdiction before trading. ### Fees **CEX fees** follow a maker/taker model. Makers (who add liquidity via limit orders) typically pay less than takers (who fill existing orders with market orders). High-volume traders unlock discounts. There are no gas fees, but withdrawals carry a fixed fee per asset. [**DEX fees**](https://docs.afx.xyz/) consist of a protocol fee (charged per trade, typically as a percentage of notional) plus blockchain gas. Gas costs on modern Layer 2 networks are minimal — often under $0.10 per trade. The protocol fee is fixed regardless of order type or volume. The practical difference is small for most trade sizes on L2 DEXs. For very large institutional-scale orders, CEX maker rebates can make CEXs more cost-efficient. For smaller traders or those avoiding KYC overhead, DEX total costs are comparable. ### Liquidity and Execution CEXs concentrate liquidity from professional market makers and institutional traders. Major pairs like BTC and ETH have deep order books with tight spreads, meaning large market orders execute with minimal price impact. For active traders running high-frequency or large-size strategies, this remains a meaningful edge. On-chain perp liquidity has grown substantially — decentralized perp volumes reached $6.7 trillion in 2025, up 346% year-over-year, representing roughly 7.8% of CEX volume according to public industry data. For standard trade sizes on major pairs, slippage on leading DEXs is now competitive with mid-tier CEXs. Thinner markets and less-traded assets still show more slippage. Execution speed differs in kind, not just degree. CEX trades settle on internal servers in milliseconds. DEX trades confirm on-chain, typically in a few seconds on modern L2 networks, but subject to block times and occasional congestion. ### Asset Availability: Where On-Chain Now Leads This is where the comparison shifts in favor of on-chain DEXs for a specific category of trader. CEXs primarily offer crypto perpetuals. Stock-linked derivatives and commodity contracts face heavy regulatory restrictions in most jurisdictions, so few CEXs can offer them to retail users globally. On-chain perp platforms are opening up a different asset universe. On AFX, you can trade perpetuals on: * **Crypto**: BTC, ETH, SOL, and others * **Equity perps**: MSTR, NVDA, TSLA, AAPL — stock-linked perpetuals with no expiry * **Metal perps**: XAU (gold), XAG (silver), settled in USDC * **Index perps**: SPX (S\&P 500) All of these trade **24/7** — including weekends and holidays, when traditional stock markets are closed. This is a structural advantage that no CEX can offer within its regulatory constraints.

They serve different needs. **On-chain perps make more sense when you:** * Want to keep custody of your funds and avoid exchange counterparty risk * Prefer not to create an account or submit identity documents * Want access to equity, commodity, or index perps trading 24/7 * Value being able to verify your own trades and the protocol's health on-chain **CEX perps make more sense when you:** * Trade at high frequency or very large size where liquidity depth and execution speed matter most * Prefer the user experience of a traditional trading interface without managing a crypto wallet * Are in a jurisdiction with clear regulatory guidance for CEX-based crypto derivatives Many active traders use both — CEXs for crypto-heavy execution and on-chain platforms for asset classes CEXs cannot offer. ### FAQ **What is on-chain perps?** An on-chain perpetual (on-chain perp) is a perpetual futures contract where order matching, settlement, collateral custody, and liquidations all happen through smart contracts on a blockchain. Users trade directly from a self-custody wallet with no centralized intermediary holding their funds. **What is perps CEX?** A CEX perp is a perpetual futures contract offered on a centralized exchange. The exchange acts as a counterparty and custodian: it holds your deposited funds, matches your orders on its internal systems, and manages liquidations via its own risk engine. **What is the difference between a CEX and a DEX?** The fundamental difference is custody and trust model. A CEX is a company that holds your funds and operates its own matching engine — you trust the company. A DEX is a set of smart contracts on a blockchain — your funds stay in your wallet, and trades settle on-chain. See [What Is a Perpetual DEX?](/basics/what-is-a-perpetual-dex.md) for a full explanation. **Are perps risky?** Yes — particularly with leverage. Both on-chain and CEX perps can result in full liquidation of your margin if the market moves against your position. On-chain perps carry the additional risk of smart contract vulnerabilities. CEX perps carry exchange counterparty risk. In either case, only trade with capital you can afford to lose entirely.
