dappOS launches spot trading functionality based on its intent infrastructure, delivering a CEX-grade trading experience
The core advantage of IntentEX lies in enabling ordinary users to directly access institutional-grade liquidity resources, with faster execution speed, lower fees, and a user experience close to that of centralized exchanges (CEX).
Navigating Web3 tides with focused insights
Introduction
dappOS is dedicated to building a complete Web3 intent layer, simplifying user operations while delivering institutional-grade execution efficiency. The three core components of the Web3 intent layer are actions, assets, and trading. Previously, dappOS launched IntentOS (the intent operating system) and Intent Assets, achieving intent-driven actions and assets. Building on these technological foundations, dappOS now introduces intentEX—a spot exchange built on intent infrastructure—further enabling intent-based trading and completing a critical piece of the dappOS intent ecosystem.
The key advantage of intentEX lies in allowing ordinary users direct access to institutional-grade liquidity resources, offering faster execution speeds, lower fees, and a user experience comparable to centralized exchanges (CEXs).
1. Background
The current market is experiencing a surge in new assets and meme coins, driving strong demand for on-chain trading. However, many existing on-chain exchanges struggle to provide sufficient liquidity, suffer from slow execution speeds, and charge high transaction fees—significantly degrading the user experience. The root cause of these issues is that an asset’s trading liquidity is often fragmented across multiple exchanges, preventing users from accessing full-market liquidity within a single platform.
intentEX, dappOS’s intent-based spot trading platform (intentEX), solves these challenges related to liquidity fragmentation, transaction costs, and execution efficiency, truly enabling intent-driven trading for users.
2. How intentEX Works
The core innovation behind intentEX is extending traditional order book mechanics by treating users’ limit orders as intent tasks delegated to nodes within the dappOS intent execution network, which can execute trades across any blockchain. This design leverages professional institutions' superior liquidity capabilities, giving tokens traded on intentEX effectively better liquidity than any single CEX or DEX. It also enables faster trade execution and lower fees for users.
2.1 Publishing an Intent Task
When a user places a limit order on intentEX, they are publishing an intent task into the dappOS intent execution network. Matching nodes within the network assign this task to the most competitive service node based on multiple factors such as stake amount, execution cost, speed, and willingness to accept orders at price deviations from the order book.
After the user signs the order, the selected service node commits to fulfilling a specific portion of the order. Thanks to dappOS’s OMS mechanism, once a service node signs and confirms exclusive fulfillment rights, failure to deliver results in liquidation. As a result, users can consider the committed portion of their order fulfilled immediately—even before on-chain confirmation. When user prices are close to the market spread, service nodes typically commit to fulfilling the entire order, enabling execution speeds faster than the underlying blockchain’s block time.
2.2 On-Chain Order Processing
After commitment, the service node processes the order on-chain in three sequential steps:
-
Internal Fill: If matching orders exist within the intentEX order book, they are immediately matched and executed. Any remaining unfulfilled portion proceeds to the next stage.
-
Node Exclusive Fill: For the remaining quantity, the service node gains temporary exclusive rights to fulfill the order. If the internal fill did not satisfy its committed volume, the node must source the remainder externally; otherwise, it faces penalties under the dappOS network rules. The node may also choose to fulfill more than its committed amount during this phase.
-
Open Order: Any unfilled portion after exclusive fill becomes publicly visible on the intentEX order book for other users to trade against.
If a service node performs slowly or consistently commits to small volumes, its competitiveness score decreases among matching nodes, reducing future task allocation. This incentivizes nodes to commit larger volumes and execute faster.
2.3 A Concrete Example
To illustrate, consider a scenario where the $A token on intentEX has 990U offered at 9.9U (best ask), and 1,010U offered at 10.1U (second ask).
A user then submits a limit buy order for 300 units at 10U. This order becomes an intent task broadcast across the dappOS intent execution network. A matching node assigns it to the most suitable service node.
Suppose a service node wins this task and commits to fulfilling at least 250 units. This number depends on the node’s strategy and real-time liquidity analysis across all markets. For instance, it might commit 250 because: (1) 100 units are immediately available on intentEX’s own order book, and (2) after scanning other DEXs and CEXs, it identifies 150 additional units available at effective costs below 10U when factoring in fees.
From the user’s perspective, 250 out of the 300 units are considered filled the moment the service node makes its commitment—this happens faster than blockchain block times. While in this example the order book depth is limited, in deeper markets, nodes often commit to filling all near-market orders entirely, giving users the impression of instant full execution.
The service node then executes according to the following process:
-
Internal Fill
Of the user’s 300-unit buy order at 10U, 100 units match with existing sell orders at 9.9U on intentEX and execute instantly at that price.
-
Node Exclusive Fill
Since the node committed to fulfilling at least 250 units, it must now ensure the remaining 150 units are filled; otherwise, it risks liquidation.
This highlights intentEX’s key advantage: instead of leaving residual orders exposed on the public book waiting for arbitrageurs, professional nodes in the intent execution network actively fulfill them. This gives users access to cross-market liquidity and accelerates execution speed.
3. Open Order
The final 50 units of the 10U limit buy order will appear on intentEX’s bid side if the assigned service node chooses not to fulfill them.
Situations like this only occur when the user’s price is far from the current market or when overall market liquidity for the token is scarce.
3. Core Advantages of intentEX
1. Institutional-Grade, Cross-Market Liquidity
Professional service nodes in dappOS continuously monitor and route orders across both centralized (CEX) and decentralized exchanges (DEX). As a result, trading on intentEX benefits from full-market liquidity.
Compared to purely on-chain routing solutions, intentEX combines on-chain and off-chain high-quality liquidity sources, delivering institutional-grade liquidity aggregation. Each user order quickly connects to optimal pricing sources, resulting in higher fill rates and faster execution—all while tapping into global market depth.
Unlike other intent architectures, dappOS’s unique OMS mechanism allows nodes to take on tasks without locking up capital (as long as they can guarantee completion). Capital can be reused across multiple services rather than being locked like LP stakes, reducing operational overhead and increasing system-wide efficiency.
2. Fast Execution Speed
By leveraging cross-platform liquidity and rapid price matching, intentEX offers significantly faster execution than standard on-chain trading. Powered by professional nodes in the dappOS intent execution network, intentEX typically completes signature verification within 500 milliseconds after user signing—faster than typical blockchain block intervals. This dramatically reduces waiting time and enables near-instant trade settlement.
Compared to other intent-based systems, this sub-block-time execution speed and seamless UX bring users closer to the convenience of centralized exchanges.
3. Low Transaction Fees
Backed by the dappOS professional node network, intentEX optimizes transaction costs down to just 0.1%—far below the typical fees charged by most on-chain exchanges. This makes intentEX a highly cost-effective choice for on-chain trading.
4. Decentralization and Transparency
All intentEX transactions are recorded transparently on-chain, ensuring auditability and trust. The decentralized architecture of the dappOS intent execution network guarantees reliable order execution—even if one service node fails, others seamlessly continue operations, ensuring uninterrupted trade fulfillment. This decentralized structure delivers a stable, resilient trading experience without reliance on any single point of failure.
4. intentEX and the dappOS Ecosystem
intentEX, the intent-based spot trading platform, is a vital component of the dappOS ecosystem. It follows earlier milestones in making actions and assets intent-driven, now extending intent capabilities to trading.
The detailed technical implementation of intentEX on the dappOS intent execution network has been explained above. For more information about how the dappOS intent execution network works, please refer to:

In addition, the USDT, BTC, and ETH used on intentEX are actually dappOS Intent Assets—specifically, intentUSD, intentBTC, and intentETH. This means users earn yield on these major assets even when not actively trading, without sacrificing immediate usability. For details on dappOS Intent Assets, see:
