If Web3 solved the issue of “who can issue assets,” Exchange OS aims to address the question of “who can create markets.”

Thousands of years ago, the market was inherently peer-to-peer. Two individuals would meet at a marketplace, one with grain and the other with cloth, and they would trade by mutual agreement without needing any authority's approval. The market naturally formed, with pricing power resting in the hands of the transacting parties.

Later on, intermediaries emerged in the market, shifting power from every stall owner to a few large-scale trading venues. Stock exchanges, commodity exchanges, regulatory bodies, clearinghouses — they determined what could be traded, who could participate in the market, and who couldn't.

With the advent of blockchain, users could engage in peer-to-peer transactions, and assets could freely circulate on the chain without the need for central institutions to mediate. However, even on-chain, the question of "who can create a market" is still dictated by a few platforms and protocols. Want to launch a perpetual contract market? Either build an entire matching engine, margin system, and clearing logic from scratch, or submit your market to a platform for approval, relinquishing pricing power and users.

Exchange OS, unveiled today by OKX, aims to fundamentally change this: by returning the right to open markets to everyone.

How Exchange OS Revives the Market

Exchange OS is an open protocol infrastructure developed by OKX based on X Layer. Matchmaking, margin trading, clearing, settlement, unified accounts — these core capabilities of exchanges have all been transformed by Exchange OS from individual closed-platform products into protocol-layer services that anyone can access. In other words, it is not an exchange but an infrastructure that can be used to construct any exchange.

Let's use a more intuitive analogy to understand: Exchange OS plays in the financial market the role that HTTP plays in the internet world. HTTP opened up the communication protocol so that anyone could build websites and services based on it without needing to create their protocols, servers, or routers; Exchange OS similarly opens up the underlying layer, enabling anyone to open markets on top of it.

If you wish to create a market, you only need to stake X Layer core assets to deploy your market on Exchange OS, including spot, perpetual futures, and prediction markets. No applications to submit, no waiting for platform approval. The core exchange abilities like matching engines, margin systems, and clearing mechanisms are already integrated at the protocol layer, ready for you to use directly. The time and effort saved can then be focused on the market you want to create.

The market operator can be a quant team, an RWA institution, a new public chain project, or any individual user who has identified a trading need and wants to turn it into a real market.

Different deployers can deploy different forms of markets based on the Exchange OS. Some choose to embed the market in a CEX App, allowing users to enter with one click, providing an experience no different from traditional exchanges. Others choose to allow users to connect directly with their self-custody wallets, retaining full on-chain sovereignty. Behind these two forms lies the same protocol foundation, with consistent rules and infrastructure. Deployers can choose the deployment method based on their own judgment of users and compliance. OKX only provides infrastructure and does not presuppose or endorse any specific compliance model.

One Account Runs All Markets

For ordinary users, the most direct change brought by Exchange OS is a significant improvement in account experience.

Today, an active on-chain trader often has to operate in multiple places simultaneously: participating in prediction markets on Polymarket, trading perpetual contracts on a DEX, buying spot on an exchange. Accounts are separate, funds are separate, and margin cannot be used across platforms. Once a new market emerges, funds need to be reallocated to the new market and a new account.

This experience is a bit like social media platforms that are not interconnected: you have one set of followers on Weibo, another on Platform X, and you have to start over on Little Red Book—every time you switch platforms, you have to re-register, reset your profile, and rebuild your network. You are doing the same thing but have to put in several times the effort. Web3 social networks initially aimed to solve this problem: using the on-chain social graph to solidify identity and relationships, one identity, one set of followers, universally applicable on all platforms. You maintain it once, and it works everywhere.

Similar to Web3 social networks, Exchange OS is doing the "unified identity and funds" in the trading world. One account, one fund, can run spot, perpetual futures, and prediction markets, with funds being universally managed at the protocol level. You participate in multiple markets simultaneously without the need for transfers, managing multiple accounts, or re-depositing funds each time a new market launches. The effort you put into maintaining one account covers all markets.

For professional traders, this means a fundamental increase in capital efficiency. The same fund is no longer locked in different platform accounts but can simultaneously serve multiple markets and strategies. While participating in a prediction market, hedge with the same margin on the corresponding asset—this level of fund reuse was almost impossible to achieve before today but is natively supported on Exchange OS.

Any Verifiable Event Can Become a Market

For those looking to create a market, Exchange OS offers another possibility.

Imagine a few scenarios: a user focused on crypto technology, who believes that the question of whether a certain L1 can surpass Ethereum this year is worth pricing; an RWA institution that wants to tokenize shares of a private equity fund for on-chain tradability; a quant team that discovers arbitrage opportunities in a small-cap perpetual contract and wants to create a market for it.

How can they achieve this? They could either build a complete system from scratch, a massive undertaking that only top institutions can afford. Or they could collaborate with a platform, but platforms have their own listing criteria, onboarding timelines, and revenue sharing requirements, and they may not be willing to create a market for a niche asset. Despite the demand, the market remains elusive.

Exchange OS directly eliminates this barrier: users can turn hot events into prediction markets, communities can turn topics into tradable judgments, and institutions can turn assets into on-chain markets. Everyone focuses on what they do best, while Exchange OS takes care of the infrastructure.

In the past, platforms decided what could be traded. It was mostly those few hundred coins, with the occasional addition of a few derivatives, and niche demands often didn't make it to the platform. Now, as long as an event is verifiable, theoretically it can become a market on Exchange OS. For the first time, the boundaries of a market are not set by the platform, but by the boundaries of verifiable events in the real world.

The significance for the entire ecosystem is this: the number and variety of markets will no longer be limited by a platform's operational capacity and willingness but by real market demand. Where there are people willing to trade, there can be a market.

Entrusting Fund Security to Code

Any discussion of open markets cannot avoid one question: Is it secure? This question is particularly weighty in the crypto market. In recent years, many platforms have attracted users to deposit assets under the guise of "decentralization," only to disappear with the funds in various ways. Users have come to realize that a platform claiming to be secure and actually being secure are two completely different things.

Exchange OS's answer to this question is: user funds are locked in the protocol contract, preventing anyone from unilaterally accessing them, including the market deployer and OKX itself. This security is not guaranteed by trusting an institution but by code and protocol rules. The protocol is publicly transparent, and anyone can audit every line of logic.

The worst-case scenario is a situation where a deployer launches a low-quality market, as opposed to the platform exit scamming with your funds. These two risks are completely different in nature: the former is a market risk, while the latter is a trust risk. What Exchange OS eliminates is the latter.

At the same time, OKX's own market on Exchange OS and any market launched by an external deployer operate under the same set of protocol rules. OKX does not have a protocol-level backdoor, platform privilege, or the ability to circumvent the rules to give its own markets the green light.

Of course, the idea that "anyone can create a market" also means that a mechanism is needed to restrain malicious behavior. Exchange OS's approach is as follows: to launch a market, a deployer must stake X Layer core assets, which serves as the deployer's economic guarantee. If the deployer's actions harm user interests, the governance committee can impose penalties on this staked asset, with the severity of the penalty linked to the maliciousness of the behavior. Opening a market incurs a cost, and engaging in malicious behavior incurs a similar cost. This is the economic foundation on which the entire mechanism operates.

Exchange OS Historical Milestones

To understand the significance of Exchange OS, it needs to be viewed on a longer timeline.

Over the past decade in blockchain, there has been a transformative milestone every so often. Bitcoin enabled the transfer of value from peer to peer, allowing people to send money without going through a bank for the first time; Ethereum enabled anyone to issue assets, opening up the issuance of tokens, a task previously reserved for institutions, to everyone; the emergence of AMMs allowed anyone to create liquidity pools without the need for professional market makers; and prediction markets made "events" tradable for the first time, expanding the market's scope from asset prices to any verifiable judgment in human society. Each step has involved opening up power that was previously held by a few to more individuals.

What Exchange OS aims to do is take the next step in this online evolution: enabling anyone to create a full-fledged financial market. What used to be something only top exchanges had the ability to build and operate has now become a protocol-layer service available to anyone. This is the liberation of market creation rights. Drawing an analogy to the evolution of the internet: in the Web1 era, content was produced by a few websites and institutions, with regular individuals only able to browse; in the Web2 era, anyone could write articles, start channels, and the right to create content spread to everyone as technology became widespread; Web3 extends this openness to the asset layer—allowing anyone to issue tokens, create liquidity pools, and significantly lower the barrier to financial participation.

What Exchange OS aims to do is take the next step on this evolutionary path: turning the act of "opening a market" into something anyone can do. If Web3 addressed the issue of "who can issue assets," Exchange OS aims to tackle the problem of "who can create a market"—which is precisely the form the next generation of financial infrastructure should take.

Thousands of years ago, anyone could open a market. What Exchange OS has done is to bring this concept back to the blockchain.
