What is Defx?
Defx is a privacy-focused perpetual DEX that uses zero-knowledge technology to keep all trades private while offering a powerful, CEX-like trading experience on-chain. It supports portfolio margin across major assets—including BTC, ETH, SOL, and stablecoins—and allows users to fund accounts from multiple chains such as Ethereum, Base, Arbitrum, Polygon, and Solana.
Built by an experienced team active in crypto since 2018 and backed by top-tier investors, Defx aims to redefine leveraged trading with privacy, flexibility, and deep liquidity.
Key Highlights
- Private trading: Zero-knowledge execution keeps all trades confidential while remaining fully decentralised.
- Portfolio margin: Use multiple major assets as collateral to maximise capital efficiency.
- Multi-chain deposits: Seamlessly fund your account from five major chains, enhancing accessibility and flexibility.

Defx Review: Defx Perp DEX
Defx’s perpetual DEX is the core of its ecosystem, built on a Central Limit Order Book (CLOB) architecture to deliver better price discovery, tighter spreads, and fair execution for all traders. Orders are matched using price-time priority, ensuring both makers and takers receive the most competitive pricing available.
Traders can interact through the intuitive UI or via APIs, and over time, Defx expects a growing share of trading activity to come from third-party applications built on its builder-code infrastructure.

Supported Order Types
- Market Order: Executes instantly at the current market price, prioritizing speed but potentially causing slippage.
- Limit Order: Executes only at a set price or better, giving full price control but no execution guarantee.
- Stop Market Order: Converts to a market order once the stop price is hit, helping manage risk or protect profits.
- Stop Limit Order: Triggers a limit order at the stop price, offering precise control over both activation and execution price.
- Take Profit Limit Order: Automatically closes a position at a preset profit target using a limit order to lock in gains.

Auto-Deleveraging (ADL)
Auto-Deleveraging (ADL) is Defx’s backstop risk management mechanism that activates during extreme volatility or when the insurance fund is under pressure. It works by automatically reducing positions of traders who pose the highest risk—those with the largest unrealized profits and highest leverage—according to a ranked list. When triggered, ADL liquidates or reduces a trader’s margin position to maintain system stability, and the affected trader is notified immediately.
Self-Trade Prevention (STP)
Defx’s self-trade prevention system ensures that a trader’s orders cannot match against each other, preventing artificial volume or manipulation on the order book. When a potential self-trade is detected, Defx uses one of three actions to stop it:
- EXPIRE_TAKER: Cancels the taker order’s quantity to prevent the self-trade.
- EXPIRE_MAKER: Cancels the maker order’s quantity.
- EXPIRE_BOTH: Cancels both orders involved.
The action taken depends on the taker order’s STP mode. If no STP mode is specified when creating an order through the API, Defx automatically defaults to EXPIRE_TAKER.

Defx Review: Fees
Defx uses a tiered fee model based on your rolling 30-day trading volume. Every day at 00:00 UTC, the system takes a snapshot of your past 30 days of activity to determine your current fee tier. All trades initially incur the Standard User maker/taker fees, and if you qualify for a higher tier, the difference is returned to you as rebates, paid out daily in USDC.
Standard User & VIP Tiers

Defx Review: Vaults
The Defx Liquidity Engine (DLE) is the on-chain market-making vault that powers liquidity for the Defx perp DEX. Users deposit USDC into a pool that runs delta-neutral strategies—avoiding directional risk while generating sustainable, real yield.
How It Works
Deposited funds are used for actively managed, market-neutral LP strategies on the Defx orderbook. The vault balances long and short exposure in real time, ensuring depositors are never betting against traders or exposed to price movements.

Yield Sources
- Funding fees captured from market skew
- Trading fees (50% of maker fees)
- Liquidation profits from executing undercollateralized positions
All rewards are distributed proportionally to depositor shares.
Deposits & Withdrawals
Users deposit USDC directly into the vault. Withdrawals require a 3-day cool-off period to maintain liquidity stability, after which principal and yield can be redeemed.
Risk Management
The DLE avoids speculative strategies, staying fully delta-neutral with protocol-enforced limits and diversified yield sources.
Upcoming: LSTs
Defx will introduce liquid staking tokens (e.g., dUSDC, dstETH) that represent vault positions, offer continuous yield, and unlock DeFi composability.
