Why ApeX Pro stands out

ApeX Pro is a decentralized perpetual exchange that takes a fundamentally different approach to DeFi trading. Rather than relying on liquidity pools or oracle-based pricing, it runs a fully non-custodial, orderbook-based exchange secured by StarkEx — the same ZK-rollup technology that powered dYdX v3 and Immutable X. The result is institutional-grade execution with the security guarantees of Ethereum.

What distinguishes ApeX Pro from other decentralized perpetual exchanges is its combination of ZK-rollup security, cross-chain accessibility, and a trade-to-earn rewards program that actively returns value to the most active traders through APEX token emissions.

Built on StarkEx ZK-rollup

Same tech as dYdX v3: StarkEx is a proven, battle-tested ZK-rollup that processes transactions off-chain and posts STARK validity proofs to Ethereum. Your funds are protected by Ethereum-level security — not just by trust in the operator.

Non-custodial orderbook exchange

True self-custody: ApeX Pro never holds your assets. You retain control through your own private key at all times. The exchange cannot freeze withdrawals or access your funds unilaterally.

Cross-chain deposits

Deposit from Ethereum, Arbitrum, BSC, Polygon, or Optimism — whichever chain holds your USDC or USDT. ApeX Pro abstracts away the bridging complexity so you can fund your account from your preferred network in minutes.

Competitive low base fees

0.02% maker / 0.05% taker are among the lowest fees in the decentralized perpetuals space. With referral code save20, these already-low fees drop a further 20%, making ApeX Pro one of the most cost-efficient venues for active traders.

Trade-to-earn rewards program

Earn while you trade: ApeX Pro distributes APEX tokens to active traders based on their trading volume. This effectively reduces your net cost of trading below even the discounted fee rate, rewarding high-volume users with meaningful protocol ownership.

How to apply the referral code

  1. Open ApeX Pro through the referral link You must use the referral link to activate the discount — there is no field to enter the code manually. Click join.omni.apex.exchange/save20 to register with the 20% fee discount automatically applied.
  2. Connect your EVM wallet Click "Connect Wallet" and select MetaMask, WalletConnect, Coinbase Wallet, or any compatible wallet. No email address, no KYC, and no account form — just a wallet signature to get started.
  3. Create your StarkEx key (one-time setup) ApeX Pro will prompt you to sign a one-time message in your wallet to derive your StarkEx private key. This is an off-chain signature — it costs no gas and only takes a few seconds. Your StarkEx key is generated locally and never leaves your device.
  4. Deposit and trade with 20% lower fees Go to the Deposit section and send USDC from Ethereum, Arbitrum, BSC, Polygon, or Optimism. Once funded, open a perpetual position on BTC, ETH, SOL, or any available pair — your 20% fee discount from code save20 is applied from the very first trade.

Fee structure with code save20

ApeX Pro charges a flat fee structure with maker and taker rates. The 20% discount from referral code save20 applies directly to both fee types, reducing your cost on every single trade regardless of size.

Annual savings estimate

The table below shows how much the 20% fee reduction saves over a year at different monthly trading volumes, based on the standard 0.05% taker rate.

Monthly volumeAnnual fees (standard)Annual fees (save20)You save
$10,000$60$48$12
$100,000$600$480$120
$250,000$1,500$1,200$300
$500,000$3,000$2,400$600
$1,000,000$6,000$4,800$1,200

These figures use the taker rate only. Makers pay 0.016% with the discount, saving even more as a percentage of total fees. Traders who also earn APEX tokens through the trade-to-earn program can offset fees further.

ApeX Pro vs centralized exchanges

ApeX Pro delivers the precision and speed of an orderbook exchange while keeping users in full control of their funds. The comparison below shows where ApeX Pro differentiates itself from the dominant centralized alternatives.

The key trade-off is leverage ceiling: centralized exchanges offer higher maximum leverage. ApeX Pro wins on self-custody, privacy, no KYC requirement, and the ZK-rollup security guarantee that your funds can always be withdrawn even if the operator goes offline.

Available trading pairs

ApeX Pro offers a growing selection of perpetual markets, all settling in USDC. The 20% fee discount from code save20 applies equally across every pair on the platform.

Major markets

BTC-USDC, ETH-USDC, SOL-USDC, DOGE-USDC, XRP-USDC, AVAX-USDC, LINK-USDC, ARB-USDC, OP-USDC, MATIC-USDC

Additional markets

ApeX Pro regularly adds new perpetual pairs based on market demand. Additional available markets include APT-USDC, SUI-USDC, INJ-USDC, TIA-USDC, ATOM-USDC, NEAR-USDC, FIL-USDC, LTC-USDC, and others. Check the live platform for the current full list of available trading pairs.

All ApeX Pro perpetuals use USDC as the settlement currency and support isolated margin mode, giving traders granular control over their risk exposure on each individual position.

The APEX token

APEX is the native governance and utility token of ApeX Protocol. It is central to three aspects of the platform: governance participation, staking rewards, and the trade-to-earn program that distributes value back to active traders.

Governance and staking

APEX holders can vote on protocol upgrades, parameter changes, fee structures, and the direction of the treasury. Staking APEX entitles holders to a portion of protocol revenue, creating a direct alignment between token holders and the long-term health of the platform.

Trade-to-earn rewards

Every trade on ApeX Pro earns APEX tokens through the trade-to-earn program. Allocations are distributed based on daily trading volume, meaning more active traders earn proportionally more APEX. These rewards can meaningfully offset trading fees — for very active traders, the net cost of trading can approach zero or even turn positive.

Fee discounts for stakers

Beyond the referral code save20 discount, users who stake APEX tokens may qualify for additional fee reductions based on their staked balance. Combining the referral code discount with staking benefits gives high-volume traders the most cost-efficient trading conditions available on ApeX Pro.

About ApeX Protocol

ApeX Protocol was founded by a team with deep roots in the centralized exchange world — several core contributors were previously at Bybit, bringing institutional-grade trading infrastructure expertise to the decentralized space. The protocol launched ApeX Pro as its flagship product: a non-custodial orderbook perpetual exchange built on StarkEx.

StarkEx, developed by StarkWare, is a ZK-STARK validity proof system that enables high-throughput, low-latency off-chain trading while settling all state transitions on Ethereum. This is the same technology that secured dYdX v3 through billions of dollars in cumulative volume. Unlike optimistic rollups that rely on a dispute window, ZK-rollups provide immediate mathematical proof of transaction validity — a fundamentally stronger security model.

ApeX Protocol has attracted investment from Dragonfly Capital, Jump Crypto, and Mirana Ventures — some of the most respected institutional investors in the crypto space. This backing reflects confidence in both the technical architecture and the team's ability to execute in a competitive market.

Since launching, ApeX Pro has processed billions of dollars in cumulative trading volume and has maintained a clean security record. The combination of ZK-rollup security, cross-chain accessibility, and trade-to-earn rewards positions ApeX Pro as a compelling alternative for traders who want the control of DeFi without sacrificing the trading experience of a centralized exchange.

FAQ

What is the best ApeX referral code? +
save20 is a verified ApeX Pro referral code that gives you a 20% fee discount on all perpetual trades. Use the link join.omni.apex.exchange/save20 to apply it automatically when you connect your wallet.
How much does ApeX referral code save20 save? +
Code save20 gives you a flat 20% discount on all trading fees. At the standard taker fee of 0.05%, you pay 0.04% instead — saving $10 on every $100,000 traded. A trader doing $500,000 per month saves $600 per year from the discount alone, before factoring in trade-to-earn APEX rewards.
Does the ApeX referral code expire? +
No. Once you register through the referral link, the 20% fee discount is permanently tied to your StarkEx account. There is no expiry date, no minimum volume, and no need to re-apply on subsequent logins.
Is ApeX Pro safe? +
ApeX Pro is built on StarkEx, a ZK-rollup with a proven track record of securing billions in trading volume. ZK-rollups provide mathematical validity proofs for every state transition — a stronger security model than optimistic rollups or custodial exchanges. The exchange is non-custodial: your funds are protected by cryptographic proofs and you can always withdraw to Ethereum, even if the ApeX operator goes offline. As with any leveraged trading, position liquidation is an inherent risk when using margin.
Do I need KYC for ApeX Pro? +
No. ApeX Pro requires no identity documents, no email address, and no account registration. You connect an EVM-compatible wallet, sign a one-time message to create your StarkEx key, and start trading immediately. Important: you must use the referral link to get the discount — there is no manual code entry field.
What is StarkEx and why does it matter? +
StarkEx is a ZK-rollup scalability engine built by StarkWare. It processes trades off-chain at high throughput and then submits STARK zero-knowledge validity proofs to Ethereum, ensuring every settlement is mathematically verifiable without requiring each trade to be processed on-chain. This gives ApeX Pro the speed of a centralized exchange while inheriting Ethereum's security. Unlike a custodial exchange, no operator action can prevent you from withdrawing your funds — the proof system guarantees it.
What wallets work with ApeX Pro? +
ApeX Pro supports MetaMask, all WalletConnect-compatible wallets (Trust Wallet, Rainbow, Argent, imToken, etc.), Coinbase Wallet, and hardware wallets connected via MetaMask or WalletConnect. Since ApeX Pro derives your StarkEx key from your EVM wallet signature, any standard Ethereum wallet works without additional configuration.
How does ApeX compare to dYdX? +
ApeX Pro v3 and dYdX v3 both used StarkEx, making them architecturally similar. The key differences today: dYdX migrated to a Cosmos appchain (dYdX v4), moving away from Ethereum's security model. ApeX Pro remains on StarkEx, maintaining Ethereum-backed security. ApeX Pro also offers cross-chain deposits from five networks, a trade-to-earn rewards program, and referral code discounts like save20. dYdX v4 has higher liquidity and more trading pairs, while ApeX Pro offers lower fees and APEX token incentives.
What is the APEX token? +
APEX is the governance and utility token of ApeX Protocol. It is used for voting on protocol upgrades, staking to earn a share of protocol revenue, and participating in the trade-to-earn program that distributes APEX to active traders based on their daily volume. Staking APEX can also unlock additional fee discounts beyond the save20 referral code discount, giving high-volume traders multiple ways to reduce their effective trading cost.
Can I use ApeX from the US? +
ApeX Pro's terms of service restrict access from certain jurisdictions, including the United States. US residents should carefully review the platform's terms of service before using it and consult local regulations regarding access to derivatives platforms. Compliance with applicable local laws is each user's own responsibility.
