Proprietary AMMs use predictive value feeds to rival centralized alternate effectivity on-chain. Here is how they work and why they’re controversial.
Skilled market makers have discovered a approach to function on Solana (SOL) with near-Binance effectivity—and it is altering how DeFi liquidity truly works.
Proprietary Automated Market Makers, or PropAMMs, remedy an issue that is plagued decentralized exchanges since Uniswap launched in 2018: passive liquidity suppliers constantly lose cash to arbitrageurs. The repair entails pushing predictive value feeds on-chain and encoding subtle buying and selling logic into good contracts.
The Core Downside With Conventional AMMs
Market makers survive by continuously updating their quotes. When Bitcoin drops from $100,000 to $98,000, they cancel previous orders and put up new ones at present costs. Miss that replace, and knowledgeable merchants will choose you off—shopping for your stale $100,000 quote when the true value is $98,000.
On Binance, inserting and canceling orders prices nothing. On-chain, each transaction burns charges. Even Solana’s low cost gasoline provides up if you’re updating quotes a whole bunch of instances per second.
Uniswap’s x*y=okay method eradicated order administration fully, however created a distinct drawback: the AMM has no thought what the true market value is. If Uniswap quotes Bitcoin at $100,000 whereas each different alternate reveals $98,000, arbs drain the pool till costs converge. Liquidity suppliers eat the loss.
Uniswap v3’s concentrated liquidity helped capital effectivity however did not repair the basic concern. LPs nonetheless get picked off except they manually rebalance—which brings again the transaction charge drawback.
How PropAMMs Really Work
PropAMMs flip the mannequin. As an alternative of ready for trades to maneuver costs, they:
Preserve predictive value fashions off-chainPush minimal value updates on-chain (usually simply 8 bytes)Let good contract logic calculate quotes in real-time
When a dealer hits a PropAMM, the contract checks present market value, volatility, counterparty id, latest commerce historical past, and the way contemporary the final replace was. Then it quotes accordingly.
The effectivity acquire is substantial. Updating a single value variable prices a fraction of changing 10+ orders on an on-chain order e book. PropAMMs can replace a number of instances per Solana slot whereas remaining worthwhile.
The Centralization Commerce-off
Here is the place it will get controversial. As trade analysts famous in October 2025, PropAMMs “echo the identical buildings crypto as soon as sought to flee.”
In contrast to Uniswap swimming pools the place anybody can deposit, PropAMM liquidity comes primarily from the operators themselves. The good contracts are closed-source. Integration with aggregators like Jupiter requires permission. Customers cannot confirm they’re getting one of the best accessible value.
There’s additionally a validator drawback distinctive to Solana. Some block producers run their very own PropAMMs and should prioritize their very own value updates whereas delaying opponents’. Others extract MEV by together with updates as late as attainable to maximise stale-price arbitrage.
The Anza workforce is reportedly engaged on fixes (referenced as “MCP”), however for now, PropAMM efficiency varies relying on which validator is producing blocks.
What This Means for Merchants
PropAMMs at the moment deal with vital quantity on main Solana pairs, notably by means of Jupiter routing. For liquid property, they usually present tighter spreads than conventional AMMs.
However they will not work for the whole lot. The transaction charge flooring means long-tail tokens with skinny quantity cannot be profitably market-made this fashion. And the closed-source, permissioned nature means customers are trusting black bins operated by nameless groups.
The know-how works. Whether or not DeFi ought to embrace these trade-offs is a distinct query—one the Solana ecosystem is actively debating as PropAMMs seize extra market share from clear, permissionless options.
