Decentralized finance (DeFi) continues to evolve, bringing users closer to seamless, high-yield opportunities across multiple blockchain ecosystems. One of the latest advancements is the launch of Compound v3 on Arbitrum, now available through a simplified yield-earning product for USDC holders. This integration marks a significant step toward user-friendly DeFi participation, combining robust protocol mechanics with accessible interfaces.
Whether you're new to decentralized lending or an experienced yield optimizer, this guide breaks down everything you need to know about earning with Compound v3 on Arbitrum — from how it works and what rewards are available, to how you can get started in just a few clicks.
What Is Compound v3?
Compound is one of the most established lending and borrowing protocols in the DeFi space. With the release of Compound v3, the protocol expanded its capabilities by introducing EVM (Ethereum Virtual Machine) compatibility, enabling deployment across Layer 2 networks like Arbitrum. This upgrade significantly reduces transaction fees and increases scalability while maintaining security and decentralization.
In Compound v3, users can:
- Deposit assets to earn interest
- Use deposited assets as collateral to borrow other tokens
- Earn governance rewards in the form of COMP tokens
The protocol operates entirely on-chain, meaning all interest rates, collateral factors, and reward distributions are determined algorithmically and transparently.

How to Earn Yield with USDC on Arbitrum
Starting July 3, 2025, users can earn competitive yields by depositing USDC into the Compound v3 (Arbitrum) vault via a streamlined on-chain earning product. Unlike traditional DeFi platforms that require complex wallet setups and manual interactions, this solution simplifies access without compromising transparency.
Key Features of the USDC Yield Product
- No subscription cap: Anyone can participate regardless of deposit size.
- True on-chain yield: All deposits are routed directly to the Compound protocol, ensuring verifiable, trustless earnings.
- Simplified user experience: No need for advanced technical knowledge — the interface guides you through every step.
- Multi-layered rewards: Earn not only interest but also incentive tokens during promotional periods.
Understanding Your Earnings
There are three primary components to your potential returns when participating in this product:
1. Deposit Interest (Variable APR)
By supplying USDC to the Compound protocol, you earn interest based on real-time market demand for borrowing. This rate fluctuates depending on utilization but is typically competitive compared to other stablecoin yield opportunities. Interest accrues continuously and is paid out when you redeem your principal.
2. COMP Token Rewards (Governance Incentives)
As a liquidity provider, you also earn COMP, the native governance token of the Compound ecosystem. These rewards are distributed weekly and automatically credited to your account. Holding COMP grants voting rights on future protocol upgrades and parameter changes.
3. ARB Bonus Campaign (Limited-Time Incentive)
To celebrate the launch, a special campaign offers additional ARB token rewards until July 15, 2025. A total pool of 100,000 ARB is shared between participants and the OKX Web3 Wallet ecosystem. These bonuses are distributed daily, providing consistent extra income on top of your base yield.
⚠️ Note: Reward amounts may vary based on total participation and market conditions. Always review current APR estimates before depositing.

Frequently Asked Questions (FAQ)
Q: Is there a minimum deposit requirement?
A: While there’s no official cap, some protocols enforce minimum thresholds for redemption due to gas costs. Check the product page for specific details before depositing very small amounts.
Q: When does interest start accruing?
A: Interest begins accruing immediately after your transaction is confirmed on the Arbitrum network. However, exact timing may depend on blockchain confirmation speed.
Q: How often are COMP rewards distributed?
A: COMP incentives are disbursed once every seven days directly to your funding account. No manual claiming is required.
Q: Can I withdraw my funds anytime?
A: Yes, but redemptions are subject to the underlying protocol’s withdrawal cycle, which may include a short processing delay due to on-chain settlement times.
Q: Are my funds safe in this product?
A: The product routes your assets directly to the audited Compound v3 smart contracts. However, like all DeFi protocols, risks such as smart contract vulnerabilities or oracle failures exist. OKX does not guarantee capital protection.
Q: Why choose Arbitrum for this product?
A: Arbitrum offers faster transactions and significantly lower fees than Ethereum mainnet, making frequent deposits and withdrawals more cost-effective — ideal for optimizing yield strategies.
Why This Matters for DeFi Users
The integration of Compound v3 on Arbitrum represents a convergence of security, efficiency, and accessibility. Historically, participating in DeFi required navigating multiple platforms, managing gas fees, and understanding complex risk parameters. Now, with structured products like this one, users gain exposure to leading protocols with reduced friction.
Moreover, incentive campaigns like the ARB reward distribution help bootstrap liquidity and encourage broader adoption — a win-win for both users and the ecosystem.
