DEXs in 2025: From Trading Tools to Liquidity Infrastructure

DEXs in 2025: From Trading Tools to Liquidity Infrastructure
Over 24% of crypto spot trading volume flows through DEXs, with no sign-ups, no custodians, and no central authorities in sight.
This isn’t just a technological upgrade. It’s a complete redesign of how financial markets operate in a trustless, programmable economy.
Decentralised exchanges (DEXs) have evolved far beyond simple token-swapping tools. They’re becoming programmable infrastructure layers for liquidity, risk, and capital coordination across Web3.
With a monthly volume of $412 billion, DEXs aren’t just changing how assets are exchanged, but they’re redefining who can access financial markets, and on what terms.
In this blog, we’ll break down how DEXs work, what makes them different, and why they’re emerging as critical infrastructure in the on-chain economy.
Let’s get started.

What Is a DEX?

A Decentralised Exchange (DEX) is a blockchain-based platform that allows users to trade digital assets directly with one another, without relying on a central intermediary to hold funds or process transactions.
Instead of using an account on a centralised platform, users connect their wallets with MetaMask or Rabby and interact with smart contracts that handle everything from order execution to settlement.
DEX enables:
  • Peer-to-peer trading of tokens using open protocols
  • Non-custodial access, meaning you never give up control of your assets
  • Global and permissionless participation, requiring no KYC or approvals
  • 24/7 market availability, with no downtime or maintenance windows
This design radically shifts the power dynamic in trading. Since users retain control of their assets at all times, no exchange can freeze funds or block withdrawals.
Trading is governed by open smart contracts, meaning no single entity decides who can participate in it and when.
Since every transaction is recorded on a public blockchain, the entire process is transparent, auditable, and resistant to manipulation.
To understand what makes DEXs truly decentralised and how they operate without intermediaries, it’s essential to examine how DEXs function.

How DEXs Work: Core Mechanics

Every DEX operates on smart contracts that autonomously handle trading logic, eliminating the need for a central authority.
These contracts manage everything from matching buyers and sellers to settling transactions, all while keeping users in control of their funds.
Instead of replicating centralised infrastructure, DEXs take a modular approach, with different components handling pricing, liquidity, routing, and execution.
Over time, this architecture has evolved into four major layers that define how DEXs operate today:

Automated Market Makers (AMMs)

Most DEXs today use Automated Market Makers rather than traditional order books.
In an AMM model, users trade against a pool of tokens provided by liquidity providers (LPs), rather than waiting for another trader to take the other side of the trade.
Prices are determined by an algorithm, most commonly the constant product formula used by Uniswap, which adjusts based on supply and demand within the pool.
This model enables:
  • Instant trades, regardless of counterparties
  • Passive income for liquidity providers via trading fees
  • Simpler UX for users and better scalability across L2s and appchains
Variants like concentrated liquidity (Uniswap v3+) and dynamic curves (Maverick, Algebra) optimise capital efficiency, letting LPs target specific price ranges or market conditions.

Order Books and Hybrids

Some DEXs, especially on high-speed chains like Solana or Layer 2s like Base and zkSync, are reintroducing on-chain order books or hybrid models.
These combine the flexibility of limit orders with the transparency of smart contract settlement.
Examples:
  • Jupiter on Solana: Liquidity aggregation across order books and AMMs
  • dYdX v4 on Cosmos: Fully on-chain order book for perpetual futures
  • Velodrome/Maverick: Hybrid routing engines that simulate order book-like behaviour via liquidity bands

Routing and Aggregation

Modern DEXs rarely operate in isolation.
Aggregators like CowSwap or MetaDEX route trades across multiple DEXs to find the best execution path, factoring in price impact, gas fees, and slippage.
Today, cross-rollup routers and intent-based execution models are beginning to take this a step further.
Instead of just submitting a trade, users can specify their intent, e.g., swap 1 ETH for the best available yield token, and the protocol handles the optimal execution path.

Wallet-Based Access and Non-Custodial Security

To use a DEX, users simply connect their self-custodial wallets. Trades are signed and confirmed directly on-chain, no logins, no centralised account management.
This design ensures that:
  • Funds remain in the user’s control until the transaction is executed
  • Every action is auditable and permissionless
  • Security is enforced by code, not by trust in third parties
These four components define how DEXs work, i.e. modular, transparent, and fully on-chain.
But understanding the mechanics is just the start. Now, DEXs have evolved into core infrastructure across every major chain.
Let’s look at where they stand today.

DEXs in 2025: Infrastructure, Adoption, and Why It Matters

Decentralised exchanges have moved beyond their original role as simple token-swapping interfaces.
Today, they represent a modular, programmable layer for liquidity coordination, risk management, and institutional-grade execution.
From individual traders to DAOs and institutional treasuries, a growing share of participants now rely on DEXs for execution, liquidity, and coordination.
This shift is visible across multiple dimensions in trading volumes, protocol design, and the strategic role DEXs now play in on-chain finance.
Let’s break that down:

A Growing Share of Market Structure

DEXs account for a significant portion of on-chain activity, often handling one-third or more of global crypto spot trading, depending on the ecosystem.
Their dominance is especially clear on Ethereum Layer 2s like Arbitrum, Base, and Optimism, where lower fees and native incentive programs make DEXs the preferred venue for both retail and institutional trades.
Rather than competing directly with centralised exchanges, DEXs are expanding into new territory and powering on-chain treasuries, executing structured DeFi strategies, and enabling permissionless access to novel asset classes.
DAO treasuries, on-chain funds, and structured DeFi products now rely on DEX infrastructure for:
  • Dynamic asset allocation
  • Automated yield routing
  • Treasury rebalancing
  • Market-neutral hedging via on-chain perps has transformed DEXs
These workflows were previously siloed to a centralised infrastructure. Today, they’re executed transparently on platforms like Uniswap v4, dYdX v4, and Maverick Protocol.

Protocol-Specific Innovation: Beyond the AMM

While AMMs defined the early era of DEXs, the market today demands far more than static swap curves.
Today, leading protocols are moving toward purpose-built execution environments, optimised for the type of liquidity, assets, and trading behaviours they’re designed to support.
This shift is driven by growing fragmentation, rising capital costs, and demand for programmable logic beyond price discovery.
Here’s a look at what’s shaping this new design landscape:

Uniswap v4

Uniswap v4 introduces hooks, which let developers embed custom logic directly into the swap lifecycle. Hooks can automate fee adjustments, perform on-chain accounting, or integrate with vault strategies, all without forking the DEX.
Hooks modularises the AMM, making it more like an execution sandbox. This unlocks advanced use cases like:
  • On-chain fee rebating for ve-token holders
  • Protocol-owned liquidity automation
  • LP vaults that reposition based on volatility
But hook execution order matters. Conflicts between multiple hooks or re-entrancy risks can break atomicity. This demands tighter review processes and standardisation across hook libraries.
If you're building on Uniswap v4, consider the hook sandboxing proposal and potential gas implications for deeply nested logic.

Maverick Protocol

Maverick abandons the traditional x*y=k model for dynamic liquidity placement, where LPs can concentrate their capital in directional ranges (e.g., only up, only down).
This unlocks much higher capital efficiency without requiring LPs to rebalance manually. For markets with trend bias like LSTs, perps, or stable-yield tokens, this reduces idle liquidity.
Trade-offs include:
  • Performance is heavily dependent on volatility assumptions
  • LPs require either predictive positioning or vault-level automation
  • Slippage protection becomes more complex in thin directional markets
Vault managers can use Maverick to simulate active LP behaviour without gas-intensive rebalancing. This is ideal for DAO treasuries or LST-focused funds.

Jupiter

Rather than hosting its own pools, Jupiter acts as the execution and routing layer across Solana’s fragmented liquidity landscape. It handles:
  • AMM routing
  • Order book matching
  • Fee comparison and slippage optimisation
In high-throughput environments like Solana, aggregation is the DEX. Jupiter's real-time pricing layer processes over 50% of Solana’s swap volume.
Trade-offs include:
  • Relies on accurate off-chain estimates for optimal routes
  • MEV and latency are harder to monitor across integrated venues
  • Security models vary by integrated pool or venue
Protocols integrating Jupiter should treat it as a coordination layer, not a passive router. You can structure vault strategies or swap-based flows using its SDK and APIs.

dYdX v4

Now fully on-chain via Cosmos, dYdX v4 delivers a CEX-grade experience with:
  • Off-chain matching
  • On-chain settlement
  • Decentralised sequencer validation
It reintroduces full control over order precision and leverage, while maintaining transparency and composability. It’s designed for institutional-grade perps, not token swaps.
Trade-offs include:
  • Latency is still higher than CEXs
  • Liquidity is segmented from other Cosmos-native DEXs
  • Not designed for DeFi-style LP provisioning
If you're building for traders, perps, or synthetic markets, dYdX offers the best on-chain performance-to-control ratio, but composability with broader DeFi is limited.
Each of these reflects a shift from general-purpose DEXs toward market structure verticalization: building purpose-specific execution environments within a decentralised framework.

DEXs as Liquidity Infrastructure

DEX's role has expanded from facilitating swaps to coordinating capital flows across protocols, vaults, treasuries, and automation systems.
Liquidity isn’t just supplied or traded, it’s referenced, routed, and repurposed across layers of programmable logic.
This evolution is being driven by three structural shifts:

Liquidity as a Shared Resource

In modern DeFi architecture, liquidity is the centre of automated workflows, not at the edge.
Vaults and structured products dynamically route user deposits into DEX pools based on:
  • Real-time yield signals
  • Risk scoring (via oracles or on-chain data)
  • Strategy modules (e.g., delta-neutral, yield-maximising, slippage-minimised)
For example, protocols like Sommelier let LP vaults reallocate capital across Uniswap, Balancer, or Maverick pools depending on real-time volatility, TVL shifts, and fee generation.
This turns DEXs into underlying infrastructure for passive yield products and active strategies alike.

Treasuries and DAOs Use DEXs as Execution Backends

DAOs today don’t just hold assets; they programmatically move them. Whether it’s rebalancing a treasury, bootstrapping a new pool, or swapping between stablecoins, DEXs are the backend for these actions.
Execution can be triggered by:
  • Onchain governance votes
  • Pre-set strategy contracts, e.g., vesting + auto LP
  • Oracle-based triggers, e.g., swap when price deviates >3%
Projects like Uniswap v4 and MetaDEX are building native support for DAO-first execution, with hooks that can encode governance conditions, dynamic fees, or automated treasury actions.
DEXs have become the middleware between treasury strategy and capital deployment.

Intent-Based Execution Makes Liquidity Modular

With intent-based protocols like CowSwap, the user's action isn’t a swap; it’s an intent.
That intent is interpreted by solvers who decide:
  • Which DEX to use
  • How to split routes across pools
  • Whether to execute directly or via meta-aggregators
This modular execution logic turns liquidity into a composable endpoint, rather than a fixed source.
For example: A user might declare, “Swap 1 ETH for the highest-yield stETH position.”
The intent engine might:
  • Source ETH liquidity from Maverick (lowest slippage)
  • Route through Curve for stETH
  • Auto-stake it in a Yearn vault
All while preserving optimal gas usage and MEV resistance.
But as liquidity flows grew and capital efficiency became critical, DEXs could no longer rely on one-size-fits-all designs.
Rising costs, diverse asset types, and advanced use cases demanded purpose-built environments tailored for specific trading behaviours.
And this shift has driven a wave of protocol-specific innovation, where new architectures focus not just on enabling swaps, but on optimising execution for distinct liquidity needs and market structures.

Strategic Relevance Beyond Swaps

The rise of DEXs has fundamentally changed not just how we trade, who gets to participate, how value is distributed, and what infrastructure governs liquidity.
Their strategic relevance today lies in two systemic shifts that are redefining the structure of Web3 finance:

User Ownership and Self-Custody

DEXs embed the principle of user ownership at the protocol level. Every trade, deposit, and liquidity action originates from the user’s own wallet and is executed by open-source contracts.
This model removes reliance on:
  • Exchange solvency or custody guarantees
  • Withdrawal policies and downtime risks
  • Platform-based access restrictions or censorship
In the context of growing regulatory pressure on CEXs and increased institutional interest in on-chain asset management, this custody model isn’t just a differentiator; it’s a compliance and trust layer.

Permissionless Access and Innovation

DEXs operate without listing approvals, token gatekeeping, or off-chain bureaucracy.
Any asset pair, incentive structure, or liquidity mechanism can be deployed by anyone with the technical capacity and economic incentive.
This permissionless layer has enabled:
  • The memecoin explosion on Solana and Base
  • RWA-backed pools governed by DAOs
  • Exotic collateral models like slippage-insured pools, ve-token boosted pairs, and single-sided staking LPs
  • On-chain structured products that rebalance automatically based on liquidity signals or oracle data
Together, these elements make DEXs not just relevant but foundational to how Web3 coordinates value at scale.
But with scale comes friction, and DEXs aren’t immune to the trade-offs introduced by modular architecture and permissionless execution.
The same factors that make DEXs powerful, composability, openness, and flexibility, also create complexity, fragmentation, and risk. Let’s unpack the core challenges shaping their evolution.

Challenges and Limitations of DEXs

While decentralised exchanges have unlocked new market structures and governance models, they still face meaningful limitations.
These challenges are often structural, not just technical, and they shape the trade-offs that DEX users, builders, and liquidity providers must navigate.
Let’s break down the most pressing challenges facing DEXs in 2025.

Liquidity Fragmentation and Cross-Rollup Complexity

As ecosystems expand across rollups, appchains, and modular L1s, liquidity has become increasingly siloed.
Even within a single ecosystem like Ethereum, users must often bridge assets between Arbitrum, Base, Optimism, zkSync, or other chains to access specific DEXs or pairs.
This fragmentation leads to:
  • Reduced depth and increased slippage on smaller chains
  • Redundant incentive programs to attract liquidity to each instance
  • Complex routing logic, often requiring aggregators or intents to unify flows
Projects like MetaDEX and Socket’s Bungee aim to solve this with unified liquidity and settlement layers, but cross-rollup trading remains an evolving space.

Smart Contract Risks and Exploit Surface

DEXs are only as secure as their smart contracts. While audit culture has matured, on-chain exploits remain one of DeFi’s largest systemic risks.
Examples include:
  • Reentrancy vulnerabilities and price manipulation attacks
  • Oracle abuse, especially in low-liquidity pairs
  • Sandwich attacks or MEV extraction in high-volume AMMs
Teams are adopting formal verification, runtime audit agents, and AI-assisted static analysis, e.g. Sherlock, Code4rena, to identify vulnerabilities early, especially for complex hooks or intents.

UX, Onboarding, and Accessibility Gaps

Despite progress, DEXs still require a steep learning curve:
  • Users must manage self-custodial wallets, gas fees, slippage, and approvals
  • Newcomers often struggle with bridging, token standards, and failed transactions
  • Error handling and fallback mechanisms are still rudimentary across most frontends
Account abstraction and intent-based execution are improving these bottlenecks, but the average user experience remains behind centralised platforms in polish and intuitiveness.

Capital Inefficiency and Impermanent Loss

While innovations like concentrated liquidity and dynamic bands help, liquidity provision is still capital-inefficient in many DEXs:
  • LPs must over-provision assets to cover wide price ranges
  • Impermanent loss (IL) can erode returns, especially in volatile pairs
  • Single-sided or auto-hedged LPing is still underdeveloped and chain-specific
Protocols like Gamma, Algebra, and Arrakis offer active liquidity management, but most LPs remain exposed unless they automate rebalancing through vaults or yield managers.

Regulatory Uncertainty and Censorship Risk

DEXs operate globally, but the lack of jurisdictional boundaries makes them targets for evolving regulatory frameworks:
  • Frontends can be geo-fenced or taken down
  • Protocol teams face legal risks even for fully decentralised deployments
  • Compliance with AML/KYC frameworks remains unsolved for most DEXs
While DEXs have made significant progress, key challenges like fragmentation, UX friction, and capital inefficiency still shape how they operate today.
The ecosystem is actively building around these constraints, not just to fix them, but to reimagine what comes next.
Here’s a look at the trends already driving that evolution.
As the market moves toward rollup-centric architectures, solver networks, and stricter compliance expectations, DEXs are evolving into specialised systems, built not just to execute trades but to coordinate liquidity, enforce policy, and operate across chains by default.
In our blog - "Top DEX Trends in 2025", we've unpacked the recent trends that are shaping this shift:
  • Intent-Centric Trading & MEV-Safe Settlement
  • AI-Powered DEX Infrastructure
  • Adaptive Liquidity & Dynamic AMMs
  • Governance and Protocol-Owned Liquidity in DEXs
  • Compliance-Ready Analytics & On-Chain KYC
