Shark Fin is a powerful financial tool designed for users who want to grow their crypto holdings with minimal risk. As a principal-protected savings product, it offers an attractive balance between security and high-reward potential—making it ideal for both conservative savers and strategic investors. Whether markets are rising or falling, Shark Fin lets you capitalize on price movements while keeping your initial investment safe.
This guide breaks down everything you need to know about Shark Fin, including how it works, the differences between bullish and bearish variants, real-world payoff scenarios, and tips for maximizing returns—all while protecting your principal.
What Is OKX Shark Fin?
OKX Shark Fin is a structured crypto savings product that guarantees principal protection and delivers enhanced annual percentage rates (APRs) based on the performance of underlying assets like BTC, ETH, BETH, and OKSOL. Unlike traditional staking or lending, Shark Fin rewards users when the asset’s price settles within a predefined range at the end of the term.
Key features include:
- 100% principal protection: Your initial investment is secure no matter how the market moves.
- Guaranteed minimum APR: Even if conditions aren’t ideal, you still earn a baseline return.
- Flexible subscription options: Choose from 1-day, 3-day, or 7-day terms with predictable outcomes.
- Multi-asset support: Subscribe using USDT, BETH, or OKSOL and earn rewards in the same currency.
- No hidden fees: Zero processing or trading fees—what you see is what you get.
- Dual market strategies: Take advantage of both upward and downward price trends with Bullish and Bearish Shark Fin products.
Understanding Bullish Shark Fin
A Bullish Shark Fin is ideal for users who expect the price of an asset—such as BTC or ETH—to rise over time but remain within a specific range by the settlement date.
How It Works
At the end of the term (e.g., 7 days), the final price of the asset is compared to a pre-set range. If it closes inside that range, you earn a variable APR—higher as the price approaches the upper boundary. If it lands outside the range (either too low or too high), you still receive a fixed basic APR.
Earnings Formula:
Final Value = Subscribed Amount × (1 + APR × Term in Days / 365)
Let’s walk through a realistic example:
- Subscription amount: 1,000 USDT
- APR range: 1% (basic) to 18% (maximum)
- Term: 7 days
- BTC price range: $18,000 – $21,000
Payoff Scenarios
Scenario 1: Price Below Range
If BTC settles at $17,000 (< $18,000):
→ APR = 1%
→ Earnings = 1,000 × 1% × 7/365 = 0.192 USDT
Scenario 2: Price Within Range
If BTC settles at $19,500 (between $18K–$21K):
→ APR = 11% (scaled based on proximity to upper limit)
→ Earnings = 1,000 × 11% × 7/365 = 2.110 USDT
Scenario 3: Price Above Range
If BTC settles at $24,000 (> $21,000):
→ APR = 1%
→ Earnings = 1,000 × 1% × 7/365 = 0.192 USDT
📌 Note: These examples are illustrative and do not guarantee future results.
This structure rewards stability and moderate growth—perfect for volatile assets where extreme swings are common.
Exploring Bearish Shark Fin
While Bullish Shark Fin benefits from rising prices within a cap, Bearish Shark Fin is tailored for users anticipating a decline in asset value—but not a crash.
How It Works
With Bearish Shark Fin, you profit when the asset expires within a defined range, with higher APRs awarded as the price nears the lower end of that range. If the price falls below or rises above the range, you still earn a guaranteed basic APR.
Earnings Formula:
Same as above: Subscribed Amount × (1 + APR × Term / 365)
Example:
- Subscription amount: 1,000 USDT
- APR range: 2% (basic) to 19% (maximum)
- Term: 7 days
- BTC price range: $18,000 – $21,000
Payoff Scenarios
Scenario 1: Price Below Range
BTC settles at $17,000 (< $18,000):
→ APR = 2%
→ Earnings = 1,000 × 2% × 7/365 = 0.384 USDT
Scenario 2: Price Within Range
BTC settles at $19,500 (within $18K–$21K):
→ APR = 11.5%
→ Earnings = 1,000 × 11.5% × 7/365 = 2.205 USDT
Scenario 3: Price Above Range
BTC settles at $24,000 (> $21,000):
→ APR = 2%
→ Earnings = 1,000 × 2% × 7/365 = 0.384 USDT
Bearish Shark Fin allows you to profit from expected dips without needing precise timing or exposure to unlimited downside risk.

Yes. Regardless of market movement, your original investment amount is fully protected. You will never lose your principal.
Q: What happens if the price lands exactly on the boundary of the range?
