In DeFi, most users are familiar with AMMs such as Uniswap-style pools. These pools let anyone provide liquidity and let traders swap against that liquidity automatically.
propAMMs are different.
They are still automated market makers, but the “prop” part stands for proprietary. That means the pricing model, risk controls and liquidity strategy are designed and operated by a professional market maker. The pool can update its pricing more actively instead of waiting for traders to move the price through swaps.
This makes propAMMs powerful. They can offer tight quotes, deep liquidity and efficient execution for certain pairs. But they also introduce new execution risks because the price shown at quote time may not always be the price users receive when the transaction settles.
What Is a propAMM?
A propAMM is an onchain trading venue that provides executable prices for token swaps using proprietary market-making logic.
In a traditional AMM, prices are usually determined by a fixed mathematical curve. For example, a constant product AMM adjusts prices based on the ratio of two token reserves in a pool. If someone buys ETH with USDC, the ETH reserve decreases, the USDC reserve increases and the price moves automatically.
A propAMM works more like an active market maker.
Instead of relying only on pool reserves, a propAMM can use an offchain pricing engine, oracle updates, inventory data and risk models to decide what price to offer onchain. Jump Crypto describes propAMMs as onchain programs that provide executable bids and offers while continuously repricing liquidity based on an offchain pricing model.
In simpler terms:
A normal AMM says, “Here is the price based on my pool curve.”
A propAMM says, “Here is the price my strategy is willing to offer right now.”
That difference matters because propAMMs can react faster to market changes. They can widen spreads when volatility rises, tighten spreads when flow is attractive or adjust pricing when inventory becomes unbalanced.
Why propAMMs Exist
Traditional AMMs made DeFi trading accessible, but they also introduced inefficiencies.
Passive liquidity providers often lose money when market prices move faster than the pool can adjust. If ETH trades at $3,000 across the broader market but a passive AMM still prices ETH at $2,980, arbitrageurs can trade against the pool until the price catches up. This helps update the pool price, but the profit often comes at the expense of passive LPs.
Concentrated liquidity improved capital efficiency, but it did not fully solve the problem. Liquidity still needs to be managed actively when market prices move.
propAMMs exist to make onchain liquidity more active.
Instead of leaving liquidity static, a professional market maker can update pricing more frequently and manage risk more intelligently. This can improve capital efficiency and sometimes deliver better quotes for traders.
How propAMMs Work
Most propAMMs can be understood as a two-part system.
The first part is the offchain pricing engine. This engine watches external markets, such as centralized exchanges, other DEXs and oracle feeds. It estimates the fair value of the asset and decides how the market maker wants to quote.
The second part is the onchain execution program. This program receives pricing updates and makes liquidity available for traders onchain. When a user submits a swap, the program executes based on the current pricing logic.
A simplified propAMM flow looks like this:
- The market maker monitors prices across different venues.
- The pricing model calculates a fair price and spread.
- The model updates the propAMM onchain.
- A trader routes a swap to the propAMM.
- The propAMM executes the trade if the pricing conditions are met.
This design lets propAMMs behave more like active liquidity engines than passive pools. They can adjust to volatility, inventory risk and market movement without relying only on arbitrage to update prices.
propAMM vs Traditional AMM vs PMM vs Order Book
| Model | How pricing works | Liquidity source | Main strength | Main tradeoff |
|---|---|---|---|---|
| Traditional AMM | Uses a public curve such as constant product | Usually public LPs | Simple, transparent and permissionless | Can be inefficient when prices move quickly |
| Concentrated liquidity AMM | LPs choose price ranges | Usually public LPs | Higher capital efficiency | Requires active liquidity management |
| PMM | Uses market-maker style pricing around reference prices | Protocol or professional liquidity | More flexible than basic AMMs | Depends on model design and liquidity depth |
| propAMM | Uses proprietary pricing logic and active market-making strategy | Professional market maker | Dynamic pricing, tight quotes and efficient liquidity | Pricing logic may be opaque and execution can change quickly |
| Order book | Uses bids and asks from market participants | Market makers and traders | Familiar market structure and clear price levels | More complex to maintain onchain |
A propAMM is closest to professional market-making infrastructure brought onchain. It still uses smart contracts for execution, but its pricing behavior is more dynamic than a passive AMM.
Why propAMMs Can Be Good for Traders
propAMMs can improve DeFi trading in several ways.
First, they can provide competitive quotes. Because professional market makers actively manage pricing and inventory, they may offer tighter spreads than passive AMM pools for certain pairs.
Second, they can improve liquidity for high-volume assets. For popular pairs such as ETH-USDC, BTC-related assets or stablecoin pairs, professional liquidity can make large trades more efficient.
Third, they can reduce the need for constant arbitrage. Instead of waiting for arbitrageurs to correct stale prices, propAMMs can update prices directly through their own pricing logic.
Fourth, they can make onchain markets more competitive. When aggregators can compare propAMMs alongside AMMs, PMMs and other liquidity venues, users can access more sources of potential output.
This is one reason propAMMs have become an important part of the broader liquidity landscape. The best swap route may not always come from a traditional AMM. Sometimes it may come from a propAMM. Sometimes it may come from a split route across several venues.
The Main Risks of propAMMs
The biggest tradeoff with propAMMs is that their behavior can be less transparent than traditional AMMs.
A normal AMM curve is public and predictable. Anyone can inspect the pool reserves and understand how the price changes after each trade.
A propAMM may expose executable liquidity onchain, but the strategy behind the quote can be proprietary. The market maker may adjust spreads, inventory limits or quoting behavior based on its own model.
This creates a key execution risk: the quote can look attractive before the transaction is submitted, but the final execution may be worse if the propAMM changes pricing before settlement.
This can happen for legitimate reasons. Markets move. Volatility changes. Inventory shifts. The propAMM may widen its spread to manage risk.
But it can also create a bad user experience if the route looked best at quote time but no longer delivers the best output at execution time.
This is where users need more than a good quote. They need better execution protection.
What Is propAMM Spoofing?
propAMM spoofing refers to a situation where a propAMM appears to offer an attractive quote during route discovery but does not deliver the same quality at execution time.
For example, a propAMM may show a tight quote that attracts aggregator order flow. But before the user’s transaction settles, the pool may widen its spread or adjust pricing. The result is that the route which looked best during quoting may become worse by the time the swap executes.
This does not mean every propAMM is bad. Many propAMMs can provide strong liquidity and competitive pricing.
The problem is the gap between quote time and execution time.
In DeFi, swaps do not execute instantly after a quote appears on the screen. Users still need to sign the transaction, submit it and wait for the transaction to be included onchain. During that window, market conditions can change.
For propAMMs, this window matters even more because pricing can be updated dynamically.
Why Aggregators Matter for propAMM Liquidity
A single DEX only sees its own liquidity. A DEX aggregator can compare many liquidity sources and find a better route across them.
This is especially important when propAMMs are part of the market.
A propAMM may be the best venue for one trade at one moment. A traditional AMM may be better seconds later. A split route across several venues may deliver the strongest final output for a larger trade.
KyberSwap Aggregator helps users access optimized swap routes across a wide liquidity network. It connects to 420+ liquidity sources across 17 chains and can split or reroute trades through capital-efficient sources to help users access better swap rates.
KyberSwap product data also highlights support for AMM, PMM and propAMM liquidity venues, alongside 420+ liquidity sources, #1 DEX Aggregator on EVM by volume and $150B+ all-time trading volume.
For users, the benefit is simple: you do not need to manually compare every pool. Aggregation helps search across liquidity venues so the swap can find a better route.
For developers, KyberSwap Aggregator API makes this infrastructure available inside wallets, dApps, trading tools, AI agents and DeFi platforms.
How Smart Settlement Helps With propAMM Execution Risk
Standard aggregation usually optimizes the route at quote time. That is useful, but it does not fully solve execution-time changes.
A route may look best when the quote is generated. But by the time the transaction settles, liquidity may shift, another user may trade first or a propAMM may widen its spread.
KyberSwap Smart Settlement helps address this by adding an execution-time decision layer to KyberSwap Aggregator.
When Smart Settlement is active, KyberSwap can prepare multiple candidate pools for a swap hop. During execution, the smart contract compares candidate pools onchain and selects the pool that gives the highest token output. This happens atomically in the same transaction with no extra user steps.
This matters for propAMMs because the best quote is not always the best final execution.
If a propAMM still provides the best output at execution, the swap can use it. If the propAMM no longer provides the best output, Smart Settlement can route through a better candidate instead.
That gives users a stronger path: not just better quote discovery, but better execution awareness.
propAMMs and the Future of DeFi Trading
propAMMs show that DeFi market structure is becoming more advanced.
The first generation of AMMs made trading permissionless. The next generation made liquidity more capital efficient. propAMMs push the market further by bringing professional market-making strategies into onchain execution.
This can be good for users because more liquidity venues can mean better competition and better output.
But it also means execution quality becomes more complex. Users need to consider not only the quoted price, but also whether that quote will still be strong when the transaction settles.
That is why the future of DeFi trading will likely depend on three layers working together:
- Deep liquidity across many venues
- Smart routing that finds the best available quote
- Execution-aware settlement that protects users when conditions change
KyberSwap is building toward this direction with KyberSwap Aggregator and Smart Settlement. The goal is not only to help users find strong quotes, but also to help them receive better outcomes when swaps actually settle onchain.
FAQ: propAMM
What does propAMM mean?
propAMM stands for proprietary automated market maker. It is an onchain liquidity venue operated by a professional market maker using proprietary pricing and risk-management logic.
How is a propAMM different from a normal AMM?
A normal AMM usually follows a public pricing formula based on token reserves. A propAMM uses active market-making logic that can adjust prices based on market conditions, inventory, volatility and external price feeds.
Are propAMMs good or bad?
propAMMs are neither automatically good nor bad. They can provide strong liquidity and competitive quotes, but they can also introduce execution risk if pricing changes between quote time and settlement.
Why do propAMMs use proprietary logic?
Market makers compete through pricing models, inventory management and risk controls. Keeping these strategies proprietary helps them protect their edge while still offering executable liquidity onchain.
What is propAMM spoofing?
propAMM spoofing is when a propAMM appears to offer a strong quote during route discovery but delivers worse pricing by the time the transaction executes. This can make the final output lower than expected.
How does KyberSwap help users trade across propAMMs?
KyberSwap Aggregator compares routes across many liquidity sources, including AMMs, PMMs and propAMMs. Smart Settlement adds an execution-time layer that can compare candidate pools onchain and select the one that gives the highest token output.
Should traders avoid propAMMs?
Not necessarily. propAMMs can be useful liquidity sources. The key is to use routing and settlement infrastructure that can compare them against other venues and protect users if the quote changes before execution.
Why are propAMMs important for DeFi?
propAMMs bring more active and professional liquidity into onchain markets. They can improve price competition, deepen liquidity and make DeFi trading more efficient, especially when paired with strong aggregation and execution-aware routing.
