dYdX is a decentralized exchange deployed on the Ethereum blockchain, classified as a decentralized finance (DeFi) application. Launched in August 2018, it offers financial services for cryptocurrencies issued under the ERC-20 protocol. Currently, dYdX supports borrowing, lending, and margin trading for assets like ETH, USDC, and Dai. Its margin trading feature resembles futures trading, allowing users to take long or short positions.
How Lending Works on dYdX
dYdX employs a model similar to Compound, utilizing liquidity pools for lending operations executed via Ethereum smart contracts. Interest rates for each asset fluctuate based on supply and demand. Although rates are variable, the lending rate consistently exceeds the borrowing rate.
Earning Through Deposits
Depositing funds on dYdX is a relatively low-risk method to earn passive income in the blockchain space. Users simply deposit cryptocurrencies into their dYdX account to start earning interest. There are no strict loan terms; funds can be added or withdrawn at any time.
Understanding Borrowing Dynamics
Interest earned by lenders is paid by borrowers. dYdX ensures all borrowers maintain sufficient collateral to cover their loans. If a borrower’s collateral value falls below a certain threshold, it is automatically liquidated.
Collateral and Liquidation Explained
Collateral ratios on dYdX determine borrowing limits and liquidation triggers. Each cryptocurrency has a unique ratio, but all require a minimum 125% initial collateral ratio and a 115% maintenance ratio. If the collateral value drops below the maintenance ratio, automatic liquidation occurs, accompanied by a 5% liquidation fee. Understanding these ratios is crucial for effective risk management.
Practical Example
Assume 1 ETH = $100 and 1 USDC = $1. If a user deposits 2.5 ETH as collateral:
- Initial Collateral Ratio (125%):
Collateral value = $250. Maximum borrowing = $250 / 125% = 200 USDC. - Maintenance Collateral Ratio (115%):
If ETH drops to $90, collateral value becomes $225. The collateral ratio is now 112.5% ($225 / 200), triggering liquidation. After a 5% fee, the remaining collateral is calculated as:
2.5 ETH – (200 / $90 * 95%) ≈ 0.264 ETH.
Margin and Leverage Trading
dYdX offers two margin trading options:
- Isolated Margin (Wallet-based): Conducted directly through a connected wallet.
- Cross Margin (Account-based): Requires transferring assets to a dYdX account wallet.
Both methods support long and short positions.
Price Oracles and Data Integrity
A robust decentralized lending platform relies entirely on blockchain technology. dYdX uses smart contracts not only for executing loans but also for sourcing asset prices through oracle technology. Oracles automatically fetch real-time prices from blockchain sources:
- ETH: Uses MakerDAO’s ETH-USD price feed.
- Dai: Calculates USD price using a combination of ETH2Dai, Uniswap, and MakerDAO oracle data.
- USDC: Fixed at 1:1 with the US dollar, as verified by Coinbase.
The dYdX Protocol Framework
The dYdX protocol leverages Ethereum smart contracts to enable ERC-20 token lending and margin trading. Its core contracts include:
- Margin Contract: Handles margin trading operations.
- Proxy Contract: Facilitates asset transfers on behalf of users.
- Vault Contract: Safeguards assets used in margin trades.
Critical Assessment
Decentralized cryptocurrency derivatives represent a fascinating market niche. Compared to traditional finance, dYdX offers decentralization and low entry barriers. However, its margin trading environment remains underdeveloped. DeFi products are still niche, suffering from limited trading depth and liquidity—key factors for growth in crypto markets. That said, dYdX provides greater transparency and security than centralized alternatives due to its public, immutable ledger.

Conclusion
Within DeFi, dYdX offers more diverse services than platforms like Compound or Dharma. As a futures-style derivative, it signals the expansion of financial services into crypto. However, mainstream adoption requires time. The platform’s limited supported assets may deter investors; expanding its cryptocurrency offerings could enhance its future prospects.
