A new economic era requires a DEX OS that is more interoperable, more responsive, and more powerful than ever. Not just to outcompete today, but to scale with the possibility of tomorrow.

That’s why we’re excited to announce MetaDEX03.

MetaDEX03 brings forward the best of MetaDEX02 and adds new and powerful features, along with an upgraded economic system that will make it the most advanced DEX OS on the market.

The most capital-efficient AMM is getting even better. Slipstream V3 will bring upgraded dynamic fees, institutional-grade features, like KYC verified pools and order flow payments, and a revolutionary new internal MEV auction.

Slipstream V3 will be the first AMM to directly integrate an internal MEV auction directly into the AMM, intercepting and capturing value that other exchanges typically leak to chain sequencers.

Each year, MEV (Maximum Extractable Value) activity generates hundreds of millions in fees, mostly paid to sequencers. When a bot spots an arbitrage opportunity, it will pay a priority fee to jump the line to ensure its swap is executed first. This generally results in a “bidding war” that ends in the maximum priority fee a bot is willing to pay and still make a profit on the trade.

In 2024, Paradigm published a paper that floated a novel solution to this issue.

MetaDEX03 will be the first exchange to implement its recommendations. Slipstream V3 will be able to detect MEV activity and live-adjust the swap fee in response to it. In effect, this will shift the lion’s share of the MEV value generated away from sequencers and to the MetaDEX. 

We project that this could generate millions in new revenue that will flow to MetaDEX Operators.

Order Flow Payments

Slipstream V3 will be the first AMM to support Robinhood + Citadel-style fee rebates and order flow payments onchain. This will allow Slipstream to give preferred rates to non-toxic flow from retail trading institutions like Coinbase, as well as support institutional global FX payments infrastructure to deliver the best rates for currency conversions and cross-border payments.

Upgraded Dynamic Fees

Slipstream V2’s dynamic fee module changed the game, adjusting fees with volatility to deliver more rewards and capture liquidity from competing DEXs. The effect was a surge pricing-like model, only possible with the MetaDEXs ability to reward LPs with a consistent stream of rewards.

In Slipstream V3, we’re making them even better, using adaptive algorithms that will smooth transitions and make them more responsive to changing market conditions.

KYC Verification

Slipstream V3 will be the first AMM designed to support the needs of institutions, adding support for institutional-grade KYC verification at the pool level. MetaDEX03 will be able to plug into any kind of ZK verification stack — from Coinbase Attestations to World ID Verifications — as well as the innovative VerifiedERC20 standard developed by Dromos Labs, Celo, and Self.xyz.

Metaswaps is a cross-chain bridge, liquidity aggregator, and swapping UI all in one — delivering an innovative and seamless cross-chain trading experience across the entire EVM. 

Using generic messages, every Slipstream pool connected to our router will be a pool connected and aggregated by all the MetaDEX routers. Quotes will be fetched in real time, and the execution speed will only be bound by the underlying stablecoin transport speed.

To keep the swaps private and secure, Metaswaps will ensure sensitive details are kept separate and sent interchain using the offchain relayer, providing seamless MEV protection to swaps.

Metaswaps will be the first cross-chain solution for swaps that doesn’t require dedicated liquidity or solvers network. And because gas fees will be automatically deducted from the stablecoin powering the swap, users won’t have to worry about having native gas.

Metaswaps will be built on a Typescript SDK making it simple to integrate for wallets, aggregators, and AI agents.

MetaDEX03 will come equipped with a powerful automation suite that makes managing liquidity and locked positions easier than ever.

For token operators with locked token positions, Autopilot will optimize weekly voting across all pools — claiming, compounding, and even converting rewards from any chain.

For Liquidity Providers: Autopilot will optimize concentrated liquidity deposits, automatically rebalancing in response to market changes. It will also support one-click zap in and even auto-compound rewards back into your position.

Metalane is the native interoperability layer built into MetaDEX03 that makes cross-chain swaps faster, cheaper, and easier than ever before. With Metalane, any Slipstream pool connected to a MetaDEX router will be connected to all Slipstream pools on any chain. Metalane will be completely vendor-neutral and will use generic messaging, a common way to deliver interchain communication and execution at the largest scale.

MetaDEX03 will also have Cockpit (enhanced analytics dashboard) and Open Pools (easy integration for launchers and projects), so more to come.

MetaDEX03 upgrades the economic engine of the system with two core innovations:

• REV Engine, which expands the MetaDEX’s ability to capture value

• AER Engine, which expands the MetaDEX’s ability to deploy value efficiently

Together, they will make the MetaDEX more sustainable, more competitive, and far more rewarding for liquidity providers and token operators.

The REV Engine takes the MetaDEX’s category-leading revenue generation and supercharges it, enabling entirely new revenue streams and token buybacks distributed to token operators. 

Today, the combined market for exchange-related services is ~$1.5 billion, including front-end fees, aggregator fees, crosschain fees, and other services that tap into the liquidity layer.

In MetaDEX03, the new REV Engine will make it possible to directly integrate these features into the core product, undercut competitors' fees, and direct the value captured to the token.

The REV Engine will use these new revenue streams to programmatically buy back the native exchange tokens off the market, providing constant, real-time buy pressure offsetting the selling of rewards by liquidity providers — and, in doing so, further enhance the ability of the MetaDEX to reward LPs at levels far above the rates of fee-only DEX models.

In short: REV Engine brings more fees in, internalizes more value, and applies continuous, programmatic buy pressure to the liquid token, all while boosting rewards for voters.

AER stands for Adaptive Emissions Rate, a system where liquidity rewards are not fixed or manually adjusted, but dynamically shaped by real onchain conditions.

It does two things: Optimize and Surge.

Optimize
AER Engine sets a dynamic emissions cap for every pool, calibrated to remain competitive while ensuring the system pays only what’s needed for healthy, growing liquidity.’

By linking each pool’s maximum rewards to the value of the fees it generates, AER keeps emissions grounded in real economic activity. The outcome:

• Reward levels stay competitive with fee-based DEXs

• No unnecessary overpayment, preserving efficiency

• Flexibility for strategic pools to grow

AER ensures the MetaDEX consistently supports deep, responsive markets, with emissions tuned to where they create the most value.

Surge

AER Engine can also boost rewards when trading activity spikes. AER responds in real time, briefly increasing token rewards so liquidity stays deep when traders need it most and helping increase trading fee rewards token operators capture weekly.

Once activity settles, emissions automatically return to normal.

The benefit:

• Liquidity stays competitive during high-volume moments

• LPs earn more exactly when their capital is most valuable

• The system remains efficient, adjusting only when justified

AER will give MetaDEX03 the flexibility to react to real conditions, without overspending.

Combined, these two powerful engines could massively improve token operator economics.

Based on even conservative estimates and backtesting, the REV engine could increase value captured by the protocol by 40% while AER engine is estimated to reduce emissions out by 25%. Put together, MetaDEX03 could create 2.8x more value for token operators than 02.

MetaDEX03 is the result of two years of research and development to make the world's most advanced DEXOS even more interoperable, more responsive, and more powerful. A DEX OS built not just to outcompete today. But to scale with the possibility of tomorrow.
