Those who have traded futures have likely seen this kind of market behavior:
A single spike wipes out your position, only for the price to rebound a few minutes later.
You might have been right about the direction—but your position is already gone. Even if the price surges afterward, you can only watch.
So when I saw f(x)’s promotion of FX100, what caught my attention first wasn’t the leverage or the trading pairs, but a very specific design feature:
“15-Minute Liquidation Protection for New Positions”
—
According to the official description during the public test phase, FX100 is a perpetual futures product deployed on the Base Sepolia testnet.
Each new position is granted an initial 15-minute liquidation protection window.
f(x) specifically highlighted this mechanism in their September Chinese community discussion.
So what exactly does this 15-minute window do?
It’s simple.
When trading short-term, it’s not just where the price ends up that matters—it’s also how it got there.
For example, you just opened a long position:
Open position → sudden plunge → liquidation triggered → price rebounds minutes later
You might have been correct about the direction.
But because of that brief volatility, your position was wiped out.
The subsequent rebound? It no longer matters to you.

FX100 aims to fix exactly this problem.
As described by the official team, during the initial protection window, new positions won’t be immediately liquidated due to price fluctuations.
In other words:
After opening a position, even if there’s a sharp, short-term price spike or drop, traders still get a buffer period to observe and manage their position.
I think this point deserves serious attention.
Because it doesn’t help you predict whether the price will go up or down—it solves another very real problem:
What if your analysis is correct, but your position doesn’t survive long enough for the market to turn back?

But it’s crucial to clarify this:
“15-minute protection” ≠ “15 minutes without losses”
The price will still fall if it’s supposed to.
Unrealized losses will still grow.
The protection window doesn’t erase your losses, nor does it guarantee the price will return.
Once the 15 minutes are over, your position still faces normal risk and liquidation rules.
So I prefer to think of it this way:
It changes how new positions handle sudden, short-term volatility at the moment of entry.
It gives you time—not a get-out-of-jail-free card.

Beyond liquidation protection, FX100 has another feature I think is easily overlooked:
One-Click Trading.
After completing the necessary authorization, you no longer need to repeatedly wait for wallet pop-ups and confirm signatures each time you place an order.
This might not sound flashy, but anyone who’s used on-chain trading knows how critical it is.
The normal flow often goes like this:
Click to place order
→ Wallet popup appears
→ Confirm
→ Wait for signature
→ Switch back to trading page
If the market moves fast, by the time you finish these steps, the price may have already moved on.
So reducing repetitive confirmations may seem like a minor UX improvement—but it directly impacts order execution speed.
Of course, convenience comes with responsibility.
You must carefully review the scope, duration, and nature of your authorization.
Know exactly what permissions you’re granting.

If you’re planning to try FX100, I’d suggest not jumping straight into max leverage on the testnet.
Instead, fully experience the 15-minute protection window.
Pay close attention to these points:
① When does the protection countdown begin after opening a position?
② How are unrealized profits and losses displayed during price swings?
③ How does the interface warn you about risk during the protection period?
④ Are there clear changes in position rules before and after protection ends?
⑤ Are margin, liquidation levels, and fees clearly and intuitively presented?
Pay special attention to this:
The 15-minute window applies only to the initial protection period of a new position.
It does not reset every time the price moves again.
Exact timing rules, whether adding to positions affects the timer, and other operational details should always be verified against the latest official documentation and on-screen information.

The reason FX100 is worth examining is actually quite straightforward:
It doesn’t just talk hollow phrases like “faster trading” or “better experience.” Instead, it directly addresses a problem every futures trader knows well:
What do you do when you get liquidated right after opening a position?
Do you have enough time to react?
Can you clearly see how much protection time remains?
Are the risk rules easy to understand?
These details may seem small—but often, it’s precisely these small things that determine whether a perpetual futures product is truly usable.
So once you hear “15-minute liquidation protection,” you already know what to test:
Don’t rush to judge whether it’s useful.
Open a test position yourself and observe the full 15 minutes. You’ll quickly see whether this mechanism deserves your attention.
