Decentralized finance (DeFi) has revolutionized the way individuals interact with financial services. Among the leading platforms in this space, dYdX stands out as a powerful, open-source trading protocol that empowers users to lend, borrow, and trade digital assets with full control over their funds. This guide focuses on one of its core functionalities: lending — a low-risk, passive income strategy that allows crypto holders to earn interest on their idle assets.
Whether you're new to blockchain or looking to expand your DeFi knowledge, this step-by-step tutorial will walk you through the entire process — from setting up a wallet to earning real-time interest on your deposits.
What Is dYdX Lending and Why Should You Do It?
Lending on dYdX means depositing your cryptocurrency into the platform’s liquidity pool, where other users can borrow it. In return, you earn interest — paid directly by borrowers. The entire process is automated via smart contracts on the Ethereum blockchain, eliminating intermediaries and ensuring transparency.
One of the biggest advantages of lending on dYdX is passive income generation. Unlike active trading, which requires constant monitoring, lending works automatically. As soon as your assets are deposited, they start earning interest by the second. There's no lock-in period — you can withdraw your funds at any time.

Moreover, dYdX ensures security through over-collateralization. Every borrower must deposit more value in collateral than they borrow. If the value of their collateral drops below a certain threshold, the system automatically liquidates part of it to repay the debt. This mechanism protects lenders from default risk.
All operations happen on-chain, meaning your assets remain under your control at all times. No registration or KYC is required — just connect your wallet and begin.
Supported Assets and Dynamic Interest Rates
dYdX currently supports three major assets for lending:
- ETH – Native token of the Ethereum network
- DAI – A decentralized stablecoin pegged to the US dollar
- USDC – A regulated stablecoin backed 1:1 with USD
Each asset carries a dynamic interest rate, which fluctuates based on supply and demand within the platform. When many users want to borrow a particular asset (high demand), its lending rate increases. Conversely, when there's an oversupply of lenders, rates go down.
You can view real-time interest rates under the “Supply APY” section on the dYdX market page. These rates update continuously, allowing informed decisions about which asset to lend.
For this guide, we’ll use USDC as an example due to its stability and widespread adoption. However, the process is nearly identical for DAI and ETH.
Getting Started: Prerequisites
Before you begin earning interest on dYdX, ensure you meet these three basic requirements:
- A compatible cryptocurrency wallet (MetaMask)
- A small amount of ETH for gas fees (transaction costs on Ethereum)
- Any amount of supported assets (e.g., USDC) to deposit
Even small deposits qualify — there’s no minimum requirement. However, keep in mind that every transaction on Ethereum incurs a gas fee paid in ETH. We recommend holding at least $5 worth of ETH to cover initial deposits and future withdrawals.
To acquire USDC or ETH, you can use trusted exchanges like Coinbase, Binance, or Kraken. On platforms like Coinbase, converting USD to USDC and withdrawing it to your wallet is typically free.
Once you've acquired your assets, transfer them to your MetaMask wallet — the next critical step in the process.
Setting Up Your MetaMask Wallet
MetaMask is a browser extension wallet that allows direct interaction with decentralized applications like dYdX. It's free, user-friendly, and widely supported across the DeFi ecosystem.
👉 Learn how easy it is to manage your crypto securely with a non-custodial wallet.
To get started:
- Visit metamask.io and install the Chrome extension.
- Follow the setup instructions to create a new wallet.
- During setup, write down and securely store your 12-word recovery phrase (seed phrase). This is the only way to recover access if you lose your device or forget your password.
After setup, your wallet will only display ETH by default. To see USDC or DAI balances:
- Click "Import Tokens" below your balance
- Search for “USDC” or “DAI”
- Select the correct token (ensure it's on Ethereum Mainnet)
- Click “Add Custom Token,” then “Next” and “Add Tokens”
Now, when you receive USDC or DAI, they’ll appear in your wallet.
To receive funds from an exchange:
- Open MetaMask
- Click your account name to copy your public address
- Paste this address into the withdrawal field on your exchange
- Confirm the transaction
Always double-check addresses before sending funds — blockchain transactions are irreversible.
Depositing Funds into dYdX
With your wallet funded and configured, you're ready to start earning interest.
- Go to the official dYdX platform
- Click the blue “Connect Wallet” button in the top-left corner
- Select MetaMask when prompted and confirm the connection
Once connected, you’ll see a green “Connected” status in the top-right corner.
Navigate to the "Balances" tab at the top of the screen.
Here’s what happens next:
- For ETH, you can deposit directly by clicking “Deposit” and entering the amount.
- For DAI or USDC, you must first "Enable" the asset for use on dYdX.
This one-time activation authorizes dYdX to interact with your token balance via smart contracts. When you select DAI or USDC from the dropdown menu, the “Deposit” button changes to “Enable.”
Click “Enable,” then confirm the transaction in MetaMask. You'll see a gas fee estimate — this is the maximum you’ll pay; actual fees may be lower depending on network congestion.
After confirmation, wait a few seconds for the transaction to be processed on-chain. Once complete, the button will change back to “Deposit.” Now you can enter the amount you wish to lend and click “Deposit” again.
Confirm the final transaction in MetaMask.
Your deposit is now pending confirmation by Ethereum miners. Depending on network traffic, this may take anywhere from 15 seconds to several minutes. Once confirmed, your dYdX balance updates instantly — and interest begins accruing immediately.
You can check your current earnings in real time under your account balances.
