StableHub Trading Rules
I. Core Trading Features
1:1 No-Slippage Exchange
Within the applicable limits, StableHub supports strict 1:1 exchanges between supported stablecoins or between stablecoins and USD, with no price deviation or slippage.
Fee Policy
StableHub offers zero transaction fees for selected supported stablecoin trading pairs.
Exchange limit
All StableHub currencies are subject to 1:1 exchange limits, including individual exchange limits and total platform exchange limits.
Excess Volume Handling Mechanism
If the order volume exceeds the 1:1 exchange limit, please note that, there are two types of handling mechanism:
Type A - Exchange Suspension: For some specific trading pairs, the exchange will be temporarily suspended for the day and will only resume once the limit resets;
Type B - Execution at market price: For other trading pairs, the entire order will continue to be executed at market prices via Flash Trade. All exchange prices will be displayed on the StableHub trading interface, and if the quoted price does not meet expectations, the user may reject the quote, adjust the order volume, and request a new quote.
The applicable execution method for each specific trading pair is subject to the latest official announcement.
II. Limit Calculation and Usage Rules
1.Limit Rules
For trading pairs subject to 1:1 exchange limits, StableHub implements a dual-layer limit control system:
Global Pool Daily/Monthly limit: The total daily/monthly 1:1 exchange limit shared across the entire platform.
Individual Daily/Monthly limit: The maximum daily/monthly 1:1 exchange limit per user (as published by the platform).
The 1:1 exchange limit is calculated based on the net buy volume and net sell volume for each currency.
Net Buy Volume = Buy Volume - Sell Volume.
Net Sell Volume = Sell Volume - Buy Volume.
Therefore, the limit requirements are as follows:
Each user's daily/monthly net buy volume must be less than their individual daily/monthly net buy limit. The sum of all users' daily/monthly net buy volumes must be less than the Global Pool daily/monthly net buy limit.
Each user's daily/monthly net sell volume must be less than their individual daily/monthly net sell limit. The sum of all users' daily/monthly net sell volumes must be less than the Global Pool daily/monthly net sell limit.
If the order volume exceeds the 1:1 exchange limit, for type A trading pairs, the entire order will be canceled; for type B trading pairs, the entire order will be quoted at market prices, with the final price displayed on the trading page prevailing.
2.Limit Calculation Principles
- Buying the designated asset (e.g., buying USDC) → deducts from both the individual and the platform buy limit.
Selling the designated asset (e.g., selling USDC) → deducts from both the individual and the platform sell limit.
The quota is calculated on a net basis (buy minus sell or sell minus buy), and only the net amount will count towards the applicable limit.
For example, if a user buys 20,000 and sells 10,000, the net buy volume is 10,000, and only this net amount will be counted towards the limit.

5.Order Execution Logic
When a user places an order, StableHub will first check the platform limit and the user's individual limit:
If both the platform and the user's individual limit exceed the proposed order volume , the order will be executed at the 1:1 price.
If either limit is lower, for type A trading pairs, the entire order will be canceled; for type B trading pairs, the entire order will be quoted at market prices (as displayed on the StableHub page). The user may cancel the order, adjust the volume to fit within the limit, or proceed with the market price quote.
6.Limit Reset
Monthly Limits: Both Individual Limits and global limits will be automatically reset at 00:00 on the 1st day of each calendar month (UTC+8).
Daily Limits: Individual and global limits will be automatically reset daily at 00:00 (UTC+8).
Emergency Reset: In the event that a limit is reached, the platform may, at its sole discretion, perform an early limit reset based on user demand without prior notice.
