As the crypto‑asset ecosystem continues to expand, investors are presented with an increasingly diverse set of ways to earn returns. On‑chain Earn and Simple Earn are currently the two most discussed product categories. The former relies on the mechanisms built into blockchain networks themselves, while the latter is a fund‑lending service offered by exchanges. Below we first compare the two from a security perspective, then explain their core differences and walk through the step‑by‑step process for beginners to get started.

In this article we outline the safety‑related differences between On‑chain Earn and Simple Earn, and provide a detailed breakdown of each model’s core mechanism and the onboarding workflow for newcomers. By contrasting risk points and platform risk‑control measures, readers can decide which approach better fits their asset‑allocation strategy. Subsequent sections will also include practical instructions, so a careful read is recommended.
Which Method Is Safer?
Overall, Simple Earn tends to have a higher safety profile, though its inherent risks should not be ignored. This model’s operation centers on moving idle digital assets into the exchange’s lending pool, where the platform distributes earnings to users based on “market‑driven rates, calculated hourly.” OKX (formerly OKEx) applies a strict risk‑control framework, centrally managing assets and allocating a portion of earnings to a risk‑reserve fund to mitigate possible borrower defaults.
By contrast, On‑chain Earn distributes risk more broadly. Returns come from blockchain network block rewards, transaction fees, or DeFi protocol liquidity incentives. The main risk factors include:
- Market‑price declines that erode the asset’s market value
- Smart‑contract bugs or exploitation attacks
- Impermanent loss in liquidity‑mining activities
Investors who are willing to spend time researching projects and selecting reputable on‑chain protocols often can achieve higher yields while enjoying the autonomy that decentralization provides.

Core Differences Between On‑chain Earn and Simple Earn
| Dimension | On‑chain Earn | Simple Earn |
|---|---|---|
| **Technical Barrier** | Requires understanding of staking, node operation, or DeFi contract details | No technical background needed; only ordinary financial actions |
| **Cost Structure** | Includes mining/node hardware, energy costs, and possible on‑chain fees | Primarily opportunity cost of capital; other fees are relatively low |
| **Earning Potential** | Can generate substantial returns during price rallies or in high‑yield protocols, but volatility is high | Returns are relatively stable, capped by the platform’s offered rate |
| **Time Commitment** | Requires continuous monitoring of on‑chain project updates, contract changes, etc. | Set the lending rate on the platform once; minimal ongoing maintenance |
| **Suitable Audience** | Users interested in blockchain technology who can tolerate higher volatility | Traditional investors or those with limited time who want a quick entry into the crypto market |
These five aspects—technical barrier, cost, earning potential, time commitment, and target audience—essentially determine the appropriate use cases and risk tolerance for each product.

How Can a Beginner Subscribe to and Redeem Simple Earn?
Flexible Simple Earn is an upgraded version of OKX’s former “Earn” product, featuring “deposit‑anytime, withdraw‑anytime, hourly interest accrual, and customizable rates.” After transferring assets into the pool, the system matches them at each full hour according to the user‑defined minimum annualized lending rate; a successful match generates interest for that hour.
Minimum Interest Threshold Rules
- Price ≥ 1000 USDT → 0.0001
- 100 USDT ≤ Price < 1000 USDT → 0.001
- 10 USDT ≤ Price < 100 USDT → 0.01
- 1 USDT ≤ Price < 10 USDT → 0.1
- Price < 1 USDT → 1 (updated daily at 00:00 UTC+8)
Tip: If you do not yet have an OKX account, you can register via the link below and download the app.
- Official OKX registration link: <https://www.okx.com/zh-hans/join/B2345>
- OKX APP download: <https://www.bitaigen.com/binance/download>
Subscription Steps
- Open the OKX app, tap the bottom navigation [Explore] → [Simple Earn].

- Choose [Flexible], search or scroll to select the cryptocurrency you wish to lend, input the [Subscription Amount], set the [Target Minimum Annualized Rate], tick the “User Agreement,” and then tap [Subscribe] to complete the process.

Redemption Procedure
On the home screen, go to [Assets] → [Earn]. You can filter the subscribed projects by token or product, tap [Redeem], enter the [Redemption Amount], confirm the destination account, and submit.

Key Points
- Assets placed in Simple Earn are used for OKX’s spot‑margin borrowing business and are only available for tokens that the platform supports for margin borrowing.
- Interest calculation: Users participate in the hourly rate auction at time T; if successful, interest for the period T to T+1 is credited at T+1. Of the accrued interest, 15 % serves as a risk‑reserve fund, while the remaining 85 % goes to the lending user.
- Rate‑setting rule: Users may set a “minimum annualized rate.” The system conducts an hourly auction ordered from low to high demand; the displayed “current annualized rate” reflects the highest bid. If the user’s minimum rate is lower than the current rate, the lending succeeds; if it is higher, the lending fails; if equal, priority is given to earlier timestamps.
*For U.S. residents, similar lending services are typically offered through Binance.US rather than the global Binance platform.*
