WEEX launches BBO Order(Best Bid Offer)
What is BBO?
BBO, also known as best bid offer, is a type of limit order. BBO allows traders to quickly set limit order prices that align with the current Queue 1, Queue 5, Counterparty 1, or Counterparty 5 prices, potentially facilitating faster order execution and better price matching. When a BBO order is placed, it is automatically adjusted to the best available price at the time of order placement.
How does BBO orders work?
When you place a BBO order, the price is determined by the BBO option you select:
Counterparty 1: For a buy order, this would be the lowest current ask price. For a sell order, it would be the highest bid price.
Queue 1: For a buy order, this would be the highest current bid price. For a sell order, it would be the lowest ask price.
Counterparty 5: For a buy order, this would be the 5th lowest current ask price. For a sell order, it would be the 5th highest bid price.
Queue 5: For a buy order, this would be the 5th highest current bid price. For a sell order, it would be the 5th highest ask price.
How is BBO different from other order types?
BBO orders automatically adjust to the best available price at the time of order placement, rather than at a specific price point that you input.
BBO orders:
Dynamic pricing: BBO orders dynamically adjust to the best-available bid or ask price at the time of order placement, such as Queue 1, Queue 5, Counterparty 1 or Counterparty 5.
Partial fulfillment and remaining quantity: If a BBO order is partially filled due to limited availability at the best price, the unfilled portion remains open in the order book at the matched price. This differentiates BBO orders from market orders, as they do not move to the next available price but stay at the initially matched price.
Non-BBO limit orders:
No automatic adjustment at order placement: Unlike BBO limit orders, these orders do not adjust to best bids or asks in the order book automatically when placing orders.
Market orders:
Instant execution at current price: Market orders execute immediately at the current market price, offering no control over the execution price.
Potential for slippage: They can experience slippage, filling at progressively worse prices until the entire order is completed.
How to use BBO?
How to place BBO orders:

Switch to Limit order In the limit order menu (between Limit and BBO), select BBO. Select your preferred option, such as Counterparty 1, Counterparty 5, Queue 1, or Queue 5 Click the Buy or Sell button and the system will place the order accordingly.
Note: BBO is not available if you set TP/SL or when placing any of the following order type:
- Post only
- IOC
- FOK

Mixin has launched USTD-margined perpetual contracts, bringing derivative trading into the chat scene.
The privacy-focused crypto wallet Mixin announced today the launch of its U-based perpetual contract (a derivative priced in USDT). Unlike traditional exchanges, Mixin has taken a new approach by "liberating" derivative trading from isolated matching engines and embedding it into the instant messaging environment.
Users can directly open positions within the app with leverage of up to 200x, while sharing positions, discussing strategies, and copy trading within private communities. Trading, social interaction, and asset management are integrated into the same interface.
Based on its non-custodial architecture, Mixin has eliminated friction from the traditional onboarding process, allowing users to participate in perpetual contract trading without identity verification.
The trading process has been streamlined into five steps:
· Choose the trading asset
· Select long or short
· Input position size and leverage
· Confirm order details
· Confirm and open the position
The interface provides real-time visualization of price, position, and profit and loss (PnL), allowing users to complete trades without switching between multiple modules.
Mixin has directly integrated social features into the derivative trading environment. Users can create private trading communities and interact around real-time positions:
· End-to-end encrypted private groups supporting up to 1024 members
· End-to-end encrypted voice communication
· One-click position sharing
· One-click trade copying
On the execution side, Mixin aggregates liquidity from multiple sources and accesses decentralized protocol and external market liquidity through a unified trading interface.
By combining social interaction with trade execution, Mixin enables users to collaborate, share, and execute trading strategies instantly within the same environment.
Mixin has also introduced a referral incentive system based on trading behavior:
· Users can join with an invite code
· Up to 60% of trading fees as referral rewards
· Incentive mechanism designed for long-term, sustainable earnings
This model aims to drive user-driven network expansion and organic growth.
Mixin's derivative transactions are built on top of its existing self-custody wallet infrastructure, with core features including:
· Separation of transaction account and asset storage
· User full control over assets
· Platform does not custody user funds
· Built-in privacy mechanisms to reduce data exposure
The system aims to strike a balance between transaction efficiency, asset security, and privacy protection.
Against the background of perpetual contracts becoming a mainstream trading tool, Mixin is exploring a different development direction by lowering barriers, enhancing social and privacy attributes.
The platform does not only view transactions as execution actions but positions them as a networked activity: transactions have social attributes, strategies can be shared, and relationships between individuals also become part of the financial system.
Mixin's design is based on a user-initiated, user-controlled model. The platform neither custodies assets nor executes transactions on behalf of users.
This model aligns with a statement issued by the U.S. Securities and Exchange Commission (SEC) on April 13, 2026, titled "Staff Statement on Whether Partial User Interface Used in Preparing Cryptocurrency Securities Transactions May Require Broker-Dealer Registration."
The statement indicates that, under the premise where transactions are entirely initiated and controlled by users, non-custodial service providers that offer neutral interfaces may not need to register as broker-dealers or exchanges.
Mixin is a decentralized, self-custodial privacy wallet designed to provide secure and efficient digital asset management services.
Its core capabilities include:
· Aggregation: integrating multi-chain assets and routing between different transaction paths to simplify user operations
· High liquidity access: connecting to various liquidity sources, including decentralized protocols and external markets
· Decentralization: achieving full user control over assets without relying on custodial intermediaries
· Privacy protection: safeguarding assets and data through MPC, CryptoNote, and end-to-end encrypted communication
Mixin has been in operation for over 8 years, supporting over 40 blockchains and more than 10,000 assets, with a global user base exceeding 10 million and an on-chain self-custodied asset scale of over $1 billion.
